Vmo9: After using this camera for a while, I tried the Canon 5D Mark III and recently made the switch. Auto focus needs improvement, as does the weather proofing. After 30 plus years of being a Nikon fanatic and after the issues with this camera causing countless shipping for maintenance and water seepage I became frustrated and ended not using it as much. Resale value was fair but not what I had thought a camera such as this would bring.
It was not easy to switch from Nikon to Canon, especially since I owned every "fast" professional lens Nikon produces. From the fisheye to the 800mm and two 400mm f2.8 lenses, it was a very difficult choice financially and also to end my loyalty to Nikon after 30 years. Selling all of my used gear and basically starting over was an adventure in itself. What I can offer is that since I made the switch the customer service that I've received from Canon has been impressive, as I'm hard on my gear and push the limits. The recent firmware update for my 5D Mark III pushed the standards even higher. It's difficult after purchasing an expensive piece of hardware to give it a thumbs down, as know one wants to admit making a bad decision.
I'm glad Leica has ventured out of the box by producing this camera, yet the clarity doesn't appear to compair to main stream Leica's.

I have used the 5D Mark III for over a year and have just finished selling my Nikon gear (sad day after being a Nikon enthusiast for 30 plus years). From auto-focus to camera build to overall quality, this camera can do it all! Even with the slow burst rate, it works well for sports and nature shooting! I can't recommend this camera enough. I have found the auto-focus system to be quick enough for Equestrian events with long lenses, such as Canons 400mm f2.8 or new 200-560mm.
I owned this camera for a few months, then sold it. I was hoping for a higher burst rate, better time to write, and faster auto focus. Perhaps looking for the updated Canon 7D, which I now patiently wait for.
This lens is over-the-top in performance, quality and deliverability! You get what you pay for in this fine lens. If you can't afford one, I highly recommend renting it. When shooting Equestrian, Football, Lacrosse or Soccer (my main focus), you are not confined by the Prime Lens focal length. The f-stop is sufficient for low light, end of day shooting. When shooting Equestrian events, this lens shines and gives the photographer the ability to quickly change focal lengths and capture the action from 200mm to 560mm! This lens has given new life into what I've never been able to accomplish and when comparing to other pros, I've noticed they too are considering (or already have) purchasing or renting one. The 400mm f2.8 is used much less and only for particular reasons. I use a mono pod but have also shot hand held and still captured incredible shots with no signs of camera shake (using a 5D Mark III or 1 DX)!Without a doubt, this lens is my favorite for shooting sports, wildlife, etc.
Personally, I would choose the Cannon 5D MIII over the Nikon D800, as the electronics in both the Cannon lens' and camera's (when matched together) are currently a notch above Nikon. As for the light leak issue, shortly after this was discovered, Cannon produced a fix and subsequent serial numbers were immediately addressed (as would any reputable camera company fix the problem):
"Concerning the EOS 5D Mark III digital SLR camera, when the LCD panel illuminates in extremely dark environments, the displayed exposure value may change.
