Canon 5D Mark III First Impressions and Mini Review

I recently rented the Canon 5D Mark III for 10 days to take on a vacation and thought I’d share my experiences here. So many people have already reviewed the camera that I’m not going to put it through the same technical paces, so this review is generally regarding what I liked and didn’t like. I also provided the customizations of the camera that I made to it, in case anyone finds that useful.

If you read nothing else beyond this sentence, this one word sums up the camera: remarkable.  I’m comparing this to my current 7D to provide a frame of reference for those familiar with Canon’s current lineup (as of mid 2012).  My only regret with my shooting is not having an ultra wide angle lens that works with the 5D III; the widest EF lens I had along was 24mm. I would have liked to have the 16-35 f/2.8 II or the 14mm f/2.8L II.

The ISO range of this camera (usable up to 12,800 with three more sort-of usable stops above that) opens up a world of possibilities. Shooting at f/16 and getting crystal clear photos in less than ideal light is easily possible. Or, shooting a sunset hand held at f/1.4, ISO 12,800 is possible while still getting very usable image quality; I actually did that, and you can see the result here.  Generally, image quality is significantly better than the 7D once I get above ISO 400 or so. Even at ISO 100, there is an extra sense of sharpness and presence in photos taken with the 5D3 vs the 7D.  My primary complaint with the 7D is noise in the image; the 5D produces super smooth images at most ISOs.  Adobe Lightroom goes a long way to fixing noise with the 7D’s images, but that only can be taken so far.

One change that was made from the 7D that I’m not sure about is the position of the zoom button (the magnifying glass button right above the image playback button). While I like that it can be set to zoom to 100% on the focus point, its position takes some getting used to compared to the zoom button on the upper right side of the camera like the 7D.

When I got the camera, the following are the settings I changed to customize the camera to how I use it.

  • I set up My Menu to have the following items: ISO speed settings, Protect images, Erase images.  The ISO speed settings allows for setting a minimum shutter speed when in Av or P mode, which is great when I’m using a wider lens like a 24mm and want to catch action with it without using M mode.  This is an awesome feature, and I’m going to miss it on my 7D. My only complaint is that it maxes out at 1/250 sec. I wish it would go up to 1/1000 sec, but I understand that to be a feature they reserve for their 1D series. The sad part is it’s just a software setting, not a limitation of the camera, that Canon chooses to impose.
  • Image quality: I set it to RAW+L. The RAW files are almost mandatory for post-processing. During my vacation, I took some high contrast sunrise and sunset photos and so RAW was very useful for putting finishing touches on the images.
  • Beep: disable. I don’t like it when the camera beeps when it locks focus. Carrying a huge DSLR draws enough attention, let alone having it beep every time focus is locked.
  • Shooting mode: silent continuous.  Unless you need the higher 6fps or the minor reduction in shutter lag that the non-silent mode provides, the silent mode produces a shutter sound that’s very quiet (it’s not silent, despite the name that the marketing folks decided to put on the feature).  Interestingly enough, silent mode seems to agitate animals at the zoo; perhaps it’s a higher pitch sound that people can’t hear.  In any event, I love it and it makes shooting so much more discreet.
  • Orientation linked AF point: select separate AF points.  This allows me to set the focusing mode to three separate settings: horizontal, and two vertical modes. This makes it very convenient to switch between, say, a focus point in the lower right of the frame for a horizontal picture and a top slightly-left-of-center focus point for portrait shooting.
  • VF grid display: enable. I really have to concentrate to make sure my horizon lines are straight, and the gridlines help quite a bit with that.
  • Custom controls. I set the DoF preview button to switch between One shot and AI Servo.  The DoF preview button is on the right side of the camera and so I can hold it down with one hand to toggle between one shot and AI servo modes. The 7D that I own has this feature, but the DoF preview button is really tiny and is on the left side of the camera. The 5d3’s position is far more usable in my opinion.

Below is a noise comparison between the two cameras at ISO 100 for the 7D, ISO 125 for the 5D3. Click to enlarge the samples. These are 100% crops of the sky. Unfortunately, the 5D3 picture has more clouds in it than the 7D did, but check out the smoothness of the 5D3’s sky compared to the 7D. These are both crops of the camera-generated JPGs and have not been processed in any way other than to crop them. There are two separate pictures followed by a single photo with the two images side by side in a single file.

To wrap this up, I would like to get this camera as soon as possible, though I’m holding off because it sets off another tidal wave of lens purchasing for me: 85mm f/1.2L II, TS-E 17mm f/4 L, 8-15mm f/4 L USM Fisheye, 24-70 F/2.8L II USM, 24-105mm f/4 L IS USM, 14mm f/2.8L II, 16-35mm f/2.8L II. The main reasons I like the camera are: quiet shooting mode, full frame image quality, minimum shutter speed in Av mode, the remarkable 61-point autofocus system, the repositioned DoF preview button (which I reprogrammed to switch between one-shot and AI servo AF modes), dual memory card slots for instant backups, and the large, bright optical viewfinder. Compatibility with my 7D batteries is a nice plus, too.

I posted a picture I took with the 5D and the 70-300mm f/4-5.6L lens and a 100% crop of that same picture as a comment on an earlier post of mine comparing the 70-200 f/2.8L II to the 70-300 f/4-5.6L lens.

Any questions, please let me know, and I’ll try to answer them.

  1. Well, I would hope the 5d3 is better! I can get a 7d and 5d2 for the same price, so it better mow the lawn, too :-). Comparing Apples and Oranges. The 5d3 is marked higher than it needs to be and Canon knows it. Would be better to wait for a price drop. I’m sure it’s a great cam, but if I’m going crazy on spending, may as well get the 1dx. :-)

  2. Thanks for the reply.

    I’m seeing today that the 5D2 has a street price of about $500 more (33% more) than the 7D. The 5D3 is about 50% more expensive than the 5D2. The 1DX is about 85% more expensive than the 5D3, so the absolute dollars required to jump to each successive camera rise dramatically.

    I agree that the 7D and 5D2/5D3 are targeted at different uses, but it’s a very real choice to be made by many. Is the 5D3 worth the money? It depends on a person’s needs and budget. As one example, if the 9-point autofocus of the 5D2 is all a person needs, great; if the 19-point autofocus of the 7D is sufficient and the crop factor is not a concern, then the 7D might work; and if 61-point autofocus is needed, then the 5D3 may fit the needs more closely. Whether the 5D3 is worth the extra money is up to each individual to determine. Moving from the 5D3 to the 1DX is not all positives, either; there are some tradeoffs to consider, including increased size and weight, substantial extra cost (a person could buy a 5D2 camera as a backup to the 5D3 for less than the 1DX), and reduced megapixels (22 on the 5D3 vs 18 on the 1DX). Likewise, with the 7D and 5D2 or 5D3, the crop factor on the 7D could be a pro or a con, and some people need the faster shooting speed of the 7D that is outpaced only by the 1D4 or 1DX.
