With the recently announced release of the Canon EOS 1D Mark IV many photographers, myself included, have a major dilemma ahead of us. It’s not that this won’t be a great camera; it appears to be a fantastic upgrade to its predecessor, the Canon EOS 1D Mark III, and it would be very hard not to love it.

The problem is that Canon really muddied the waters in the SLR market with the recently issued Canon EOS 7D.  Although these two cameras have different target markets, their feature sets overlap in many areas and a lot of photographers will find both to be very attractive.

The main difference between the 1D series cameras and the rest of the SLR’s in the canon family is that the 1D’s are designed to be much more rugged, much more weather proof, and built to much tighter tolerances.  These things definitely have value, but how much is going to be a personal opinion.  For the price of the 1D Mark IV you can pick up 3 of the 7D’s.  It will be very compelling for many people to buy a much cheaper camera that has most of the high end features of a more expensive model.  In fact many people will never even take advantage of all of the high end features found in the 7D, never mind the few extra offered by the Mark IV.

My personal dilemma is that what I really want is a  mix of the two cameras.  I’ve been looking forward to buying a new camera for almost year, but none of the available cameras fully met my needs, and I was happily and patiently waiting for the right camera to show up.  Now there are two cameras that get me most of the way there, but neither takes me all the way.  Unfortunately it appears that the less expensive model is missing a couple of the main features that were on my “must have” list:

• Autofocus that works with lenses (or combinations of lenses and teleconverters) having a maximum aperture as small as f/8
• Auto Exposure Bracketed (AEB) sequences of more than 3 images

The 7D also falls short of the Mark IV on my list of “high wants”:

• expanded usable ISO range
• integral battery grip
• only 1 memory card slot

The 7D does have a couple of features that I wish the Mark IV includes:

• built-in popup flash with wireless E-TTL Speedlite master flash transmitter
• dedicated Live View/Video mode start/stop button

While these features would be really nice to have, I can easily live without them.

Putting all of this together, I’ve decided that my next camera will be the Canon EOS 1D Mark IV.  The Canon EOS 7D looks to be a great contender, but for me it just doesn’t quite match up where it counts. 

What would you decide if you were in my position??

The recent release of the Canon EOS 7D has created quite a stir in the photography community. Initially people weren’t sure where this camera fit into the lineup of existing Canon cameras. From the naming convention it appears to fit somewhere between the 50D and the 5D Mark II; however, the feature set is so impressive that many assumed that it was intended to slot in above the 5D in the hierarchy. As the dust has settled it appears more and more that Canon has created a new product line designed to directly fight the Nikon D300s which is positioned in the market in a place where Canon had no comparable equipment.

Marketing aside, the 7D has a very impressive list of specifications and the image quality appears to be at least as good as the 50D (with increased resolution at 18 megapixels for the 7D vs. 15 megapixels for the 50D). It may not quite match the standard set by the full-frame 5D Mark II, but this is clearly one of the best SLR cameras ever produced.

Here are a few of the main reasons why I’m excited by this addition to the Canon family:

1. New Autofocus System: I’ve had the Canon 40D for almost 2 years (and 70,000 images) and in that time I’ve never really loved the autofocus system. It works well in some situations, poorly in others, and OK in most. But I’ve always felt that it could be faster and more accurate, and could do more to help me achieve critical focus. For the 7D Canon is boasting that the brand new “19-point, all cross-type AF system equipped with dual diagonal cross-type sensors in center at f/2.8 and f/5.6 and AF area selection modes to match various shooting situations” will be exactly what I’ve been asking for: faster and more accurate. I certainly hope they’re right.
2. Low Light / Low Noise Shooting: It seems that I can almost always use a little bit faster shutter speed and so higher ISO’s with lower noise levels are definitely exciting. I use ISO800 all the time with my 40D and the noise in those images is “acceptable” but often much uglier than I want it to be. In my opinion ISO1600 is not at all usable except in those extreme situations where getting any shot is better than getting nothing at all. I was able to test a 50D for an extended period and on that camera I find the images made at ISO1600 to be comparable to those at 800 on my camera, and the 7D is supposed to be even better yet. This is a very good thing and I’m excited at the possibility of having a camera where ISO3200 is a reality, not just a crazy dream!
3. Lots of Megapixels: 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 means that I can crop my images tighter and post yet still have a large file for multi purpose use. So while I’m happy that this camera is 18 megapixels, I’d be even happier with more. Canon, keep the pixels coming!
4. HD Video: This isn’t so much exciting for me as it is very interesting. I don’t shoot a lot of video, but I do want to be able to in a pinch. I’m used to always having a point and shoot nearby to use for the occasional video that I want to shoot, but it would be much nicer to have it built into my SLR. The fact that the 7D includes 1080p High Definition video, with the amazing control over depth of field that only comes with an SLR is really nice. Video has already become a de facto industry standard for SLR’s, but I’m glad that Canon is pushing the quality envelope with the video capabilities implemented in this camera.
5. Wireless Flash Control: I’m saving the best for last with this one… The 7D comes with built-in capability to control multiple external Speedlite flashes wirelessly using TTL metering. That means that the camera can control the output level of each flash where in the past an external flash with Speedlite Master capability, or a dedicated wireless Master controller, had to be mounted on the hotshoe of the camera. These units are heavy, bulky, and expensive! Canon has long been way behind Nikon in this one little detail as most (all?) Nikon SLR’s have been able to control slave flashes wirelessly for a long time. Anyone even remotely aware of the Strobist movement will immediately understand why this is a big deal. It’s not just big, it’s huge!

I don’t necessarily think that the Canon EOS 7D is the perfect camera. In fact it only adds one of the features that I really want in my next camera (AF Microadjustment, which has also already become a de facto industry standard feature). But it is a huge leap over the existing xxD cameras and in many ways an improvement over the much more recent 5D Mark II. The main thing for me is that it shows that Canon hasn’t been sitting on their laurels and that they have some fantastic new technology ready to roll. Upcoming releases in the 1D and 5D series could get very exciting!
