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??

For interest’s sake, here is a table I put together showing a comparison of the key specifications for both cameras:

Today Canon announced the upcoming release of the next camera in the professional EOS 1D series, the Canon EOS 1D Mark IV. Although this camera physically appears to be almost identical to it’s predecessor (the 1D Mark III), the new camera brings a host of new and upgraded features to the table.

The most notable new feature is the addition of high definition 1080p video and a jack for an external stereo microphone, while the biggest improvement over the previous release is the vastly expanded ISO sensitivity, which ranges all the way up to a whopping 102,400 in extended mode.

According to Vincent Laforet, on this camera “6400 ASA is the new 1600 ASA – maybe even the new 800 ASA”. Check out his video “Nocturne” which was shot using the 1D Mark IV locked at ISO 6400. The video is a bit cheesy but the image quality is amazing!

Here is a summary of some of the other specs for this camera:

• Sensor: APS-H (1.3x) Crop Factor
• Processor: dual DIGIC IV
• Resolution: 16.1 Megapixels
• ISO: 100-12,400 by default, 50-102,400 in extended mode
• Autofocus: 45 user selectable points (39 cross-type)
• Shutter: 10 fps max, shutter rated to 300,000 cycles
• Metering: 63-zone sensor, 0 to 20EV range
• Memory Cards: 2 card slots (1 each for CF and SD/SDHC)
• Battery: Canon LP-E4 (same as in the 1D Mark III)

The camera is due out in December of 2009 and will list at an MSRP of $4,999. Ouch.
