As I have previously mentioned, the Canon EOS 7D looks like a pretty amazing camera. It has an impressive list of features and there are a few things that it brings to the table that have me really excited.

However, amazing as it is, the 7D is still missing several features from my ideal camera, and even more from my list of must-haves for my next camera. Here are a few of the main reasons why I don’t plan to buy the Canon 7D:

1. Autofocus at f/8: Most consumer cameras will only autofocus with lenses that have a maximum aperture of f/5.6 or larger (remember that the smaller the f-stop, the larger the aperture). This may not sound like a big deal since most professional lenses are f/2.8, and even consumer lenses typically range from f/3.5 to f/5.6. However, super zooms are often at f/4 or f/5.6, and if you add a teleconverter to the lens you will lose 1 or 2 stops further. My most used lens is the Canon 100-400mm f/4-5.6 L. It is a fantastic lens under most conditions but simply adding a 1.4x teleconverter takes it up to a maximum aperture of f/8 when fully racked out and so I lose autofocus with most cameras. (Sure, some will argue that this lens is not a good candidate for teleconverters anyway, but sometimes you need all the focal length you can get and the trade-off in image quality is worth the extra zoom). Professional cameras often extend the allowable autofocus range to f/8. If the 7D had this one feature it would be a very strong contender to be my next camera.
2. Integral Battery Grip: I don’t often need more than one battery, even for a full day of shooting, and I’m very happy to carry a spare battery in my pocket. But the really nice thing about having a battery grip on your camera is that it provides an extra set of shooting controls (including a shutter release, main dial, AE lock/FE lock and AF point selection) designed to make vertical shooting easier and more comfortable). You can buy add-on battery grips for most cameras however they are not always the perfect solution. Inadequate weather sealing is one potential drawback, and they also do not always have all of the controls that would be included on an integral grip. One feature in particular that I want in my battery grip is the inclusion of an AF-ON button, but add-on grips typically don’t include one. The 7D doesn’t have an integral grip, and the Canon BG-E7 battery grip designed for the 7D doesn’t include an AF-ON button.
3. Not Enough Megapixels: I already mentioned this in my previous article about the 7D, but it’s worth mentioning here too… Lately lots of people have been crying for the camera companies to stop chasing megapixels and focus more on reduced image noise. Not me. I want both! I shoot lots of birds and wildlife which can often be very small in the frame, and more megapixels would mean that I could crop my images tighter in post, yet still have a large file for multi-purpose use. I was expecting this camera to be at least 21 megapixels, which would be comparable to the Canon 5D Mark II. I really hope the next professional camera from Canon gets back to the winning ways of more and more megapixels.
4. Single Memory Card Slot: I’m a backup freak and the most vulnerable point in any photography storage system is at the time of capture. If a camera has only one memory card slot, then, by definition, at the time of capture there is only one copy of each image that has been created. The simple addition of a second card slot would ensure that there are always at least two copies of every image. This would be a relatively inexpensive feature to add and I’m extremely disappointed that Canon missed this one on the 7D.
5. Exposure Bracketing: Most Canon cameras provide a simple method to create a 3-stop auto-exposure bracket. In traditional film photography bracketing was used almost exclusively to ensure that you got the correct exposure. In digital that’s no longer really necessary because you can easily see the image on the LCD and decide whether you got it or not. Today bracketing is used more for HDR photography than anything else. For this reason it is often desirable to have (many) more than 3 images in the bracket. Personally I prefer 5 shots in one stop increments, so I have to shoot 2 brackets of 3 shots each in order to get all the exposures I need. Nikon cameras and Canon’s professional cameras allow much more control over bracketing. It is such a simple thing to provide (a software change only), so I’m stunned that Canon did not include this feature in the 7D. HDR photography is the hottest and most exciting thing in the photo world today (just do a quick search of HDR on Flickr to see what I mean) and Canon really missed the boat here.

I’m really excited by the possibilities that the Canon EOS 7D opens up, especially with the new autofocus system and with the built-in wireless flash controller. But Canon missed a few features that could have taken this camera from “exciting” to “damn near perfect”. I’m not saying that I will never buy this camera, but for now I’m planning to hold out for the next release in the 1D series (1D mark IV ??). Hopefully it comes sooner than later!!
