Focus Stacking With The Camera’s Help

One of the functions that my new camera has built in is a focus stacking function. I know this is not unique to this camera but it is a first for me so I was keen to play with it. The mode, when enabled, allows you to set how many shots you want taken and set a scale for how close the focus points will be to each other. You then pick you initial focus point and set it off and it takes the sequence of shots incrementing the focus slightly between each one.

The resulting stack of images can then be processed in Photoshop to get the focus stacked output. This is so much nicer than making minor focus adjustments by hand between shots. The sequence gets created really quickly. I also was able to do reshoots easily. On one of the sequences, I had left it on auto ISO so it shot at a really high ISO level. I could reshoot with the ISO set low (tripod mounting means this was not a problem) in no time at all. (As an aside, the focus stacking algorithm actually seems to do a good job of reducing noise as well.)

I experimented with how fine a scale to use. Initially, I was taking way too many shots with very little movement through the image so I coarsened up the scale a bit. The nice thing was, if it didn’t go all through the range, I could just hit the shutter again and it would keep going. Photoshop chunked through the processing pretty well. I was shooting a few things but also experimented with some coins on my desk. Not the most original subject but one that shows the result well unlike the other things I was shooting. The software seemed to struggle a little on some of the coin edges so maybe a finer shoot next time or maybe I should just hand blend those bits.

Giving the R3 A Workout At Nellis

Leave a reply

I had given the R3 a couple of trips out before I headed to Nellis. I had shot it at BFI and at Juanita Bay. However, my trip to Nellis was the first time it was going to really be given a serious blast with constant shooting and varying conditions. How would it perform and could it be the camera for me for the next few years?

First, I should point out that I have not yet had a proper investigation of the various functions of the camera and how to configure it. Consequently, I was not using it in the best way I could but was instead experimenting with it as I went. So, given that limitation (of me, not necessarily the camera), how did it go? Overall, things were very impressive. Let’s start with the simple things.

Battery life was really good. I shot a little late on the first night, all of the second day and the beginning of the third on one battery. I had spares with me but the battery life, while maybe not as long as for the 1DXII, was still very good. It is also a nice thing that I can recharge with a USB-C charger if I need to which means not taking the large battery charger with me.

Autofocus was very impressive. When things are a long way off, it is still guessing at what to look at and that is something I need to investigate. However, it seemed to recognize planes very early on and then track them very effectively. The ability to let it track a target allowed me to worry about composition far more than I used to with center point focus. I could move planes to the edge of the frame to get a wingman in and still have focus working well.

Exposure was okay. I have the viewfinder set up to give me the exposure simulation which is handy for understanding what the camera is seeing. This helped me out once when I have managed to change the ISO to 800 by accident. Not sure how I did that but I was able to notice it quickly. However, I am not so sure about how quickly it adjusts as conditions change. Moving from a cloudy background to blue sky provides a rapid change that the camera needs to accommodate and it sometimes seemed a little slow to work it out. When shooting raw, your have some latitude to adjust afterwards, of course.

Handling was good. It felt good in the hands and I am wondering whether I will miss the hand grip I have used in the past. The controls are good. The smart controller is neat but it does get adjusted a lot without realizing. I also am so used to using center focus that I sometimes assume that I have to keep the subject in the same space to keep it in focus, not realizing that I can re-center things with the camera following things. I did struggle to work out how to chance the card that I was using. I found a way but it was not as simple as for the 1DXII.

Image stabilization is something that is causing me a lot of trouble. It isn’t the performance of the stabilization. That is really impressive. What I am struggling with is that the stabilization switches on and then stays on. I can put the camera down for a while and I can still hear the IS motors in the lens whirring away. Eventually they switch off but this seems like it is really chewing battery life. I have tweaked a few things to reduce it but, on the 1DXII, the IS would switch off after about 20 seconds. Why it this happening? Again, this may be my failing but I would like to understand why it happens and try to switch it off.

Frame rate is very impressive. I rarely switched it up to the 30fps setting. 15fps was blasting through the cards at a prodigious rate as it was so no need to make things any worse. I have the audio shutter turned on so I have something to remind me when I am taking too many shots and to hopefully keep things under control. However, while the frame rate may notionally be similar to the 1DXII, it consistently hits it which does result in a lot more photos than I was used to. More culling to come I guess.

Having the ability to connect to my iPad and phone is a real benefit. I used to just have this with the M6 and I really liked that. Being able to connect to the R3 gives me a lot of flexibility. I was able to send a few shots to a friend while out in the field. I will use this sporadically but it is definitely a good capability to have.

Overall, it was a great experience. I had two bodies with me but I focused on shooting with the one R3 and the other body, a 1DXII, stayed in the bag almost all of the time. I had it ready in case but didn’t end up using it. At no point during the time there did I think about reverting. I do still have a few tweaks to work out with how to set the camera up but it was a very positive experience. I think that this camera might be the one for me.

First Experience With The R3

Leave a reply

My 1DXII bodies have been doing sterling work for the last five or so years and continue to be reliable. In the interim, the camera world has made a shift from SLR technology to mirrorless. Canon was a slow starter in this space but has since got in to gear. I am not an early adopter and waited until something came along that really appealed to me. The R3 body was that thing. It combines the latest of the mirrorless technology with a body like the 1D series and the associated great battery life. It was enough to make me take the plunge.

Getting one was a different story. I ordered one in the fall of 2021. I wanted to get one first to work with it and make sure it was the thing for me before committing to a pair of them. Recently, I got the call that my body had finally come in. I was very excited to try it out. I then got a call from the store within an hour of the first saying that the second body was on. I had ordered this much later with the intent of knowing whether I was happy or not before it showed up. I decided to defer it and see how things went. I think the credit card was pleased with that decision too!

I have now had a week of playing with it having shot some aviation and some wildlife. I have not really had a chance to dig deep yet so this is just first impressions. Overall, it is really impressive. The ergonomics are familiar after years of shooting with 1D bodies. However, the controls are more complex and things are not identical so I am taking a while to get comfortable with where everything is. This will probably take me a while.

Battery life has been very good. I was expecting it to be worse than the 1DXII but it seems to have stood up to a lot of shooting with tons of life left. New batteries don’t hurt of course and we shall see how things play out. The small megapixel bump is fine but it really is barely noticeable compared to the 1DXII. 24Mp versus 20Mp might sound like a big increase but when you look at the linear pixel count it is only a small increase.

Autofocus is amazing and confusing. Its ability to pick up targets and then track them across any part of the image is fantastic. It seems to have very good accuracy and I am liking the shots I am getting. Eye detection on wildlife is spookily good. However, I don’t yet know how to control the autofocus properly. There are so many ways to customize things that I have yet to understand. For example, I haven’t yet worked out how to make it focus on a center spot only like my old setup. Most of the time, the clever stuff is more useful but there are odd times when you want it to do something simple. With small subjects or cluttered backgrounds, this can be important.

I also have to get used to pressing the button when I pick up the camera. I am used to looking through the viewfinder to sight a subject before pushing anything but the viewfinder shuts off after a while and needs to be woken up. It would be good if that could be done with some motion sensing (maybe it can and I haven’t found it yet).

I have tried the eye control a little. It seems to work pretty well. Calibration with my glasses was fine and the contract lenses were okay too but I have put that to one side for now while I leaned to understand a whole bunch of other functions of the camera. I have also connected it to my phone and iPad which has been a handy thing to do. I did briefly experience with the automatic focus stacking which seemed to work well and I shall try more of that in due course. I haven’t tried any video yet at all.

I have had to change my cards and card readers since both of the card types are new to me. That was a nuisance but not the end of the world. I actually bought them a while back so I wouldn’t have to worry about it now. I got the 24-105 lens in the RF mount. My old 24-105 was a bit beaten up and the image quality was not strong so a replacement seemed like a good idea. They had been as rare as rocking horse poo but fortunately were in stock when I went in so I got one. I also have the convertor for my other lenses and they seem to be working extremely well. The combination with in body stabilization has improved them too and I find some of the tracking of moving subjects in the viewfinder easier than it used to be – something which I attribute to the IBIS.

Overall, I am happy so far. Definitely some things to work on understanding. At the time of writing (versus publishing), I am about to go on a trip when I shall shoot a lot of planes. This will be a big test but the initial experience makes me think it should go well. The camera tracks the cockpit of planes like the eyes of a bird so I am feeling confident it will be good. I think the conversion to mirrorless is going to be complete for me based on what I have seen so far but within the next month, I should know whether it will work for me or not.

Going Mirrorless

Being late to the party is something that I make a habit of. You could also be more optimistic and say that I am not an early adopter. A number of friends and colleagues have added a mirrorless body to their collection of gear and I have followed suit. I am perfectly happy with the performance of my SLRs. This was to add something rather than replace something. The primary interest was in size and convenience. There are times when lugging the heavy bodies around is just inconvenient.

I went with an EOS M6. I did consider going with a different manufacturer but using other equipment I already have was one factor. Another was that this camera gave me an option I was quite keen on. It has a screen for use while shooting but it also has an optional viewfinder to slot into the hot shoe. This was discounted to only $11 when I bought the camera. I like a viewfinder hit am okay with a screen. Nancy, on the other hand, does not like screens so the viewfinder can be brought along if required and will make her happier to use the camera.

So far my experience with it has been very good. Image quality has been fine, the controls are good and let me make adjustments without needing to enter menus. The flippy screen is really handy and the kit lens fits plenty of needs. The app that works with it is also pretty handy which gives a few options I wish the SLR could match! The time lapse functionality is good too. I have not tested it fully with my range of lenses and will do so at some point. However, for what I bought it for, it is doing the trick nicely.

1DX Mk II First Impressions

Leave a reply

After a little bit of time shooting with the 1DX MkII, I have started to build my impressions of how it is working for me. This is definitely only a first impressions review since there will be a lot of time before I have got totally used to it and have worked out the details of its functionality. For reference, I have previously been shooting with the 1D MkIV so things have moved on a lot from that.

Focus is a good place to start. I didn’t have a particular problem with the MkIV but this one does seem to be a bit snappier when it comes to focus. I was recently shooting some subjects which had a lot of scope for the focus to get confused. However, it seemed to be reliably on target – certainly far more than I used to experience. There are a multitude of focus points and combinations. I haven’t even started to get into them yet. I tend to have simple requirements of the focus points, generally based around the center point but I will be trying more in due course.

Exposure has thrown up a couple of things of note so far. First is the amount of light you get with a full frame sensor. I have read a few things about the way camera manufacturers reference ISO and aperture combinations with crop bodies but I hadn’t had a chance to explore this. Using the same ISO and aperture as I used to, I am getting shutter speeds noticeably higher than before. I will now revisit what my settings are since I don’t need speeds that high. The other change is in the handling of backlight. I had got a good grip on what exposure compensation I needed for various sky conditions with the previous body. Starting with those resulted in overexposure. I find the body is better able to get it right itself so I have been tweaking the exposure comp down.

Video capabilities have been significantly expanded but I have yet to get too far into them. I started out with the default HD settings but I have changed to a larger file size format to get more latitude for editing. Having not done any detailed editing yet, I have not found out how much of a difference this makes. I have not played with 4K at all yet. The big thing in video is the dual pixel autofocus. Previously I had to fix focus before the shot started and any zooming would tend to move things out of focus. Now I can select by touch what I want to track and the camera seems to do a nice job of keeping that sharp during motion, panning or zooming. This is a nice addition to have when dealing with motion relatively close in.

The setup of the control buttons is an evolution of what I know. There are some additional buttons to work with and they are configurable. I haven’t tried reassigning anything yet since I want to find out what I need most often before I do so. They have made a switch in the stills to video control with that now having its own control. I am still getting used to it compared to the way I did it on the MkIV but I firmly believe the new configuration will be a big improvement. I just need to retrain myself to use it without thinking.

Preset configurations are a great addition. I moaned about this to a Canon rep many years ago. The 40D had preset configurations you could program and switch between quickly. When shooting props and jets, this is a nice thing to be able to do very quickly. Everything about the setup is programmed so it is a powerful addition. Finally I have it on a better body. There are three presets. I have one for jets, one for props and the third I have configured so I can give the camera to someone else to shoot without having to explain back button focus and center points. It is in a more user friendly configuration to hand off. I shall see whether that gets much use or not.

The card configuration is now CFast in one slot and Compact Flash in the other. The camera came with a 64Gb CFast card and I have put existing 64Gb CF in the other slot. So far I have not had to use the CF so I haven’t noticed the write speed. Buffer is huge so I doubt this will be an issue. The CFast is working fine. It does seem to download very quickly via the USB3 card reader that was also included. The card does also get noticeably warm when working a lot. No specific upside or downside so far. The CFast is required for 4K at 60fps but otherwise CF will work fine.

Now for one of the big surprises. Canon has upped the frame rate to 14fps. It was 12fps on the 1DX and 10fps on my old MkIV. I did not think that this would be a big deal. A small increase? I was wrong. This thing flies along. A quick squeeze of the shutter and suddenly I have three shots. It buzzes rather than has the sound of individual actuations. This means a slight variation of shooting technique for me. I used to shoot short bursts for each view. I could then pick my favorite of the burst during post processing. I can still do this but now it is a shorter hold of the button to get the same effect.

A small addition I like is the built in GPS. I have been using an app on my phone to create a gpx file tracklog during photo shoots. I can then import this in Lightroom and it matches with the shot times to tag the images. With a built in GPS, the shots are automatically tagged. This will help when flying which often meant I couldn’t get the tracklog to work in the old process. As a aside, the GPS allows the camera time to automatically update so no need to plug them in periodically to get the time synced up.

I can’t overlook the fact that the 1DX MkII is a full frame camera. I was a little concerned about losing the crop factor I had on the MkIV. Shooting aircraft sometimes makes the extra reach of the crop factor helpful. The pixel density is a little below what it was before so I don’t have the virtual crop to play with. However, so far I am finding that I am just shooting like normal based on what I see in the viewfinder. We shall see if I notice the difference as I get to do a variety of shoots.

File size is a step up as a result of the higher pixel count. This is resulting in a bit more effort for the computer when it is rendering the shots. I can see a noticeable difference in the speed with which the 1:1 renderings get completed. This is not yet causing a problem but I shall see whether a bottleneck develops. I will also see how this impacts my backups. I previously used to back up files in blocks of 1,000 per Blu-ray disc. If there were no video or large edit files, the disc would have spare capacity. Currently, it looks like I might still be able to do the same thing but with less margin. Another thing to watch as experience is gained.

Battery life is officially down on the previous camera. The increased processing power requires more juice from the batteries. I have been on a couple of big shoots on consecutive days with many thousands of shots over the days without having gone through one battery. If there is a reduction, it is certainly not causing me any operational concerns.

That summarizes everything I have identified so far. I have a long way to go in learning to make good use of the camera but I have to say I am very happy with it so far. It is a great piece of kit. I have much to still try. I have not even got in to the high ISO capabilities at this point. This is something I want to play with before too long. Longer days will make that a bit trickier but the opportunity will present itself. When I do, anticipate a post on that too! Overall, I love it. Anyone want to buy a MkIV?

Update on the 100-400

1 Reply

Nearly a year ago I got the new model of the Canon 100-400 EF lens. I had it on back order when it first came out and it arrived just before Christmas so became an impromptu gift to me! Almost everything about the lens I liked. However, if you read my initial thoughts on the lens which I covered here, you will have seen I had a concern about softness in one part of the image. I have used the lens extensively since then and, while I have not always had an issue, I have continued to be concerned about the output in one area – particularly when compared the the excellent sharpness the rest of the image was displaying.

I sent the lens to Canon earlier this year for a service. I explained my concerns and they took a look and told me it was functioning properly and returned it. I took it on another shoot and got more shots which did not look right. This time I emailed CPS and provided them with some sample shots. They suggested it didn’t look right and told me to send the lens back in with a description of everything to date along with more sample images on a card.

I now have the lens on its way back to me. Here is what they found.

Your product has been examined and it was found that the optical assembly was broken causing the auto focus to operate improperly from time to time. The 6th group lens and 2nd group lens were replaced. Product functions were confirmed.

It is nice to know that I wasn’t imagining things but a little disappointing it took this long to get to the bottom of things. Of course, I could have done some of this sooner if I had been more certain of the problem. In future, I will be a bit more willing to trust my instincts. Now to get the repaired lens in my hands and test it!

A New Body

Leave a reply

Not for me of course. A new camera body. A new one for me might be good but I have to stick with the one I have I guess! There has been a lot of information floating around the web for a while about what the next body might be from Canon. I have been paying particular attention to this as I have been considering getting another body for a while.

The reason for my interest is that I would like to replace one of my existing bodies. I have two broadly similar cameras but there are of different vintages. The more I have shot with them both, the more apparent the problems have become with switching from one to the other. There are little issues that become noticeable over time and there are capability differences that also have a bearing.

The little differences are surprisingly important. Canon changed the control arrangements between the release dates of these two designs and switching quickly between them can result in me using the wrong button combinations. I have back button focus set up on my cameras and they use different buttons for this. A small issue but one that is a nuisance when you are in a hurry. (They also have different batteries which is inconvenient although not the end of the world.)

The newer body has greater capability in low light, better frame rates and something that I never thought I would care about – video. It turns out I shoot more video clips than I ever expected. When you have two bodies set up with different lenses, it can be a pain to realize that you want to shoot a quick video but the appropriate lens is on the non-video body. Therefore, two identical bodies would be better.

Consequently, I nearly bought a second body earlier this year. Then the earthquake hit and they became a rare commodity. For ages they were unavailable. Then they would occasionally show up but by then, talk was of the next body coming out. I was in a quandary. Do I wait for the next evolution and risk having another pair of mismatched cameras or do I forgo whatever enhanced capability there may be and have identical bodies?

Today I got some clarity in that Canon announced the new body. As expected, it merged the two lines to create a full frame camera with high frame rate capability. This is very appealing as a full frame sensor was something I did want to get. Canon seem to have been clever and not gone crazy with the pixel count. At 18Mp, it is only slightly more than the current body (so no panic over replacing cards, computers and hard drives to cope with huge files) but this is with a full frame sensor so actual pixel density is slightly reduced. This is not something I am too concerned about.

However, I do have different sensor sizes between bodies. I would have video for both which is a plus. The button configuration has been tweaked again. However, it does seem to be that the key interfaces are still the same and some of the changes are things I have thought about myself. The battery is changed which would have annoyed me but it appears to be the case that the batteries are backwards and forwards compatible so that should be fine.

There is a stumbling block of course – price! Canon has been edging up the price of the APS-H cameras for a while getting them closer to the full frame version pricing. With the merger of the line, it appears that they have got to a price point closer to the full frame version. Have we been trained to accept this? Maybe. What will the street price be? We shall have to wait and see. Am I going to buy one or get a duplicate of the current model while it is still available? I don’t know. I have nearly six months before they become available so I guess I have plenty of time to think about it and get saving!
