              No flip out screens to break and impossible to properly weather seal. No built-in flash to eliminate a high quality pentaprism and create a new weather sealing point failure.


              You guys need to figure out how to properly compare cameras based on important things, not the specs you get off the side of the box?


              Shoot birds in flight, a night time football game, a candle lit wedding reception, etc. . . These reviews are pointless.

              Track a race car and shutter off 25 shots, how many are sharply in focus? Well I guess that would depend on how you set up the camera.


              Don't read this junk and pick a camera based on this sites comparisons, they are useless at telling you what you really need, what is going to deliver the best image quality for your typical shooting.


              Just because a camera can shoot at 100,000+ iso doesn't mean you should ever do this. Unless of course you plan to post grainy images of big foot running past your campsite at night.


              I would much, much rather shoot the 1d4 at a football game or birds in flight than the 5D3 (which i own now), as I know I will get a lot more quality, in focus, images. I would rather shoot the 5D3 at a wedding than the 1D4 (which I am looking to buy used). I would rather shoot my 50D than the 5D with a 500mm lens of birds in flight! I'd get better shots and an equal keeper rate (based on experience with my 50D and 5D3 with a 500 mm lens). But lost most photographers shooting birds, I like the advantage of the crop bodies and the 50D has very good focusing power and is faster than the 5D3.

              what is start up delay? Is this turning the camera on? My 5D3 takes several seconds to start up, go through its internal test and "clean" itself. Or do you mean when the camera goes to sleep and you depress the shutter button part way?

              Very well done! The only things you missed :1D - Looking Professional, stronger, more shutter clicks?, vertical shooting comfort, more stable?
