Canon 100-400 Review

One of the longest running sagas in the world of camera equipment watchers was the replacement of the venerable 100-400 zoom lens. I have had the old version for about ten years and it has been a useful workhorse for me. However, it was becoming a little unreliable in recent years. A trip to Canon came back with a clean bill of health but I still found it a little trickier to get good results with. I had totally given up on the image stabilization as I found it often made things go strangely, particularly in the view finder.

Consequently, I have been keeping an eye out for when the new lens was due to come out. I planned to replace mine when the new one showed itself. As it was, I had been waiting of quite a while. Then, at the end of 2014, the new lens was released. There was not a glut of them available (and at the time of writing they are still pretty hard to come by) but I placed an early order and a couple of days before Christmas, it showed up on the doorstep.

First impressions had to wait as it was taken away to become a gift. However, once I did get it in my hands, I was quite impressed. For those that aren’t following these things (and if you are interested, you probably are following them), Canon have changed from the push-pull style of zoom to a ring operated zoom. This is like most other zoom lenses and it seems to work well. However, they have made the zoom ring the outer ring which is the opposite of my 70-200 so makes for a little adjustment. It does mean that the focus ring is where your hand might be when bracing the camera for steadiness. However, this has not been an issue for me yet.

I took the old and the new lenses out for a shoot to see how they compared. I shot with each in turn as well as doing some comparison shots to see how much they varied. It was interesting that, when I imported the images into Lightroom, I went through them to cull the poor shots and found the rejection rate would go up and down. This was when switching from one to the other. The newer lens seems to have a higher rate of keeping focus for moving subjects (surfers in this case). The bodies were the same so the lenses were the only variable.

I quickly adjusted to the new lens and find it easy to work with. It certainly feels solid and there isn’t the play I found with the old version. The image stabilization is a major improvement. It is great for static subjects with a major improvement in steadiness. It has three modes – static targets, panning targets and a third mode that only starts the stabilization when you fire the shutter. I have played with that but have not found it to be so reliable. I suspect it is a lack of understanding on my part. However, I think Mode 2 for panning will be where mine stays.

Aside from focus, how is the image quality? Pretty impressive. In the comparison shots things were a little sharper all over but more so at the edges. I will have a word of warning here though. I have had a series of shots where one side was noticeably blurred. What I have not been able to break down is whether that is a focus plane issue, a haze issue or a problem with the lens. I have tried a number of test shots to try and get to the bottom of this but everything seems to be solid. There is possibly an issue around the 300mm mark in some one test I ran which does coincide with what I have experienced in the field but it is far less than I had seen before. However, I have had plenty of good shots so I suspect the issue is not with the lens but with what I was shooting.

The new lens hood is one that leaves me with mixed feelings. Overall, it is good. The newer lens hoods on Canon lenses now include a button to lock it in place which stops them dropping off at odd moments. This one also includes a small “window” in the side of the hood to allow you to adjust polarizers without taking the hood off. This is a nice enough idea but the sliding panel over this window, while having a detent, is easily disturbed and I frequently find it is open. Not a huge problem but a bit of a compromise in the design.

My remaining issue is not with the lens but with Lightroom. Adobe have not created a lens profile yet (or rather not released one) which I suspect means it will be in the new version of Lightroom which is supposedly imminent. I have shot a lot of stuff wide open with the lens and there is some vignetting which is not a big problem but having a well worked out correction profile will be very helpful.

Overall, I am very happy with the lens. It seems to perform very well. Once I have convinced myself the minor problems I have seen are down to me rather than the lens, I shall relax into this being a regular part of my kit. It doesn’t have the low light capability of the 70-200 but it might find itself being used more for shoots when that lens was previously in the bag. We shall see.

Flying Out of The Bay Area

Leave a reply

I have been traveling a reasonable amount recently and on one of my trips we took off from Oakland and flew out over San Francisco Bay, past the city and the Golden Gate and up to the north. The first time, I had my camera with me but it was in my bag in the overhead locker. My phone was still to hand of course so I grabbed a few pictures with that. They were passable but nothing special. I also was fighting some reflections given the time of day and the position of the sun.

When I came to make the same trip again, I planned ahead and did two things. One was to have my camera with me rather than in the overhead and the other was to bring the Lens Skirt to try and cut down on the reflection issues. My methodology for having the camera to hand involves yet another camera bag but I shall leave the description of that to another post.

I should point out that on the first outing, I got interesting pictures both out and back. The second time, the weather was not so cooperative. On the outbound leg, the Golden Gate was shrouded in fog with the bridge just poking out of the top of the clouds. On the return leg, most of the bay was shrouded in cloud so the views of Oakland that I had got with my phone were obscured. Here is a selection of the shots. I will be making this trip again no doubt so will probably try and get a better selection. Shooting out of airplane windows is problematic and not usually the source of great images but airliners do get you in places that have views that are unusual and worth recording, even if they are not going to be published.

Cheap Macro

Leave a reply

While the idea of trying macro photography has always been of interest to me, I have never got around to actually doing it aside from an old lens I had in my pre-autofocus days that had a macro setting. The idea of renting a macro lens had occurred to me but the reason to do it hadn’t come up and I didn’t feel like renting the lens without having something to use it on.

Then I remembered reading about reversing a lens to use it for macro. I have a 50mm that I I hand held in reverse to see how well the macro effect would work. It seemed pretty good so I decided to get a mounting ring to reverse the lens on the camera. Amazon came up with a bunch of options and the one I got set me back the enormous total of $8!

The simple answer is that it works. It is a little inflexible to use compared to something designed for the task but it does work. The depth of field is extremely shallow and you get some odd distortion across the edges of the image. Obviously there is no focus or exposure control. I just set the camera to aperture priority mode and dial in the normal f/1.8 of the lens and the exposure seems to work out pretty well. Then it is a case of moving the camera around to get focus. Not something I am going to do a lot but, for $8, I don’t have to worry about getting a lot of use out of it!

Lightning Up the Mood

Leave a reply

A little night shooting today and a confession about my role in what was going on. We moved to Chicago eight years ago. When we first got here, we were amazed by the storms we got. There seemed to be lots of them and they were really pretty spectacular. When looking out of the window we would see lightning all the time. Sometimes the storms went on for so long it was hard to believe that it was a storm and not someone planting an emergency vehicle outside the window – a neat trick at the height of our place!

Strangely, for the last few years, we have had very few storms. They seem to miss the city and go either north or south of us. Some people are getting a lot of them but not us. This was a bit disappointing to me because I love storms! They are so dramatic and very cool. They are, of course, rather destructive but watching them is exciting. This week we got a good storm. The sky was alive and it was a lot of fun. It was also rather late and I needed to go to bed. Consequently, I cheated.

My 17-40mm lens is not enough to cover the full view south of us so I went with the fish-eye zoom instead. I set the camera up on the tripod, added the intervalometer and basically set it on its way. The gap between the shutter closing and the trigger for the next shot was just long enough to allow the file to write out. Then I went to bed. The result is a LOT of pictures with almost all of them of no use. However, it did capture a couple of shots that I really like. I even tried using the new lens correction facility in Photoshop CS6. Our view is a little less impressive since the Trump Tower blocked a big chunk of the skyline but it still gives a nice look to the storm. Hope you like them too.

Something Fishy

Leave a reply

Let’s get the statements of the obvious out of the way first. Yes, I am a bit of a “gear head”. I am quite partial to stuff! Does this mean that I sometimes get things that I don’t necessarily “need”? Yes, of course. Having got past that, let’s move on.

One thing I have been pondering for a while on the lens front was a fish-eye. Not something that is needed on a regular basis but something that has its moments. Canon had a couple of fishes that I was looking at. They had the 8mm fish and the 15mm fish, both of which had things that interested me. Which one was better for me? My two main bodies are 1.3 crops but I do have a couple of APS-C sensor cameras which have the 1.6 crop. All of this impacts the effect. Besides, when buying lenses, who knows whether I will have a full frame camera at some point.

The result of all of these variables was that I never bought a fish-eye at all. I just pondered what I should do at length and did nothing in the mean time. Imagine, then, my delight when Canon announced the introduction of the 8-15mm fish-eye zoom. Have they been bugging my thoughts to find out what I want? I guess so. That reminds me, I must start thinking more about other things I want them to develop!

Of course, the announcement of a new lens does not mean the availability of a new lens. Recently, it seems the announcement can be far ahead of the delivery. Obviously the issues in Japan resulting from the earthquake and tsunami have had a major impact but I suspect there is more to it than that. Anyway, the thing is finally in the wild. My friend Jim Koepnick was the first person I saw to have one. They would appear in stores and be gone almost as fast. No biggie since it wasn’t like I had been struggling without it. Once they were regularly in store I placed my order.

I have to say, I love the thing. It feels great in the hand and, despite what I have heard from some reviews, I have had no issues with the lens cap. It is also a chance for me to start learning what can be done with such a lens. There are the obvious effects you can get and the access to a lot of width in tight spaces. However, it can also create interesting effects by changing the angle at which you hold it.

I went out in the city to give some time to experimentation. I ended up in Millennium Park which is a slightly odd place to play with a fish since many of the features already have a slightly “fishy” look to them anyway. Of course, that does sometimes allow the subject to be more tolerant of some distorting effects. It was a fun place to shoot since it is always busy and getting close and using the fish provides some options as well as making surrounding people disappear into the background quite quickly.

I also played around with a couple of effects. There is a metal frame across the lawn at the Pritzker Pavilion. By tilting the camera down, I could really emphasise the curvature but by tilting it up, the frame became almost totally flat. Something to remember. I also played around with slightly rotating the camera. This made the edge of the frame level and the receding horizon appears to turn up dramatically. Not something to overdo but still a concept to remember for the future.

I am certainly happy that I have added the fish to the arsenal. Now I have to make sure I make good use of it without slipping over the edge into using it when I shouldn’t. Hopefully my friends will warn me if that is the case. That, and I have to remember to keep myself out of my own shots!
