First the handling of well-placed power button on the top left to fall (as in the 7D). This is a matter of taste. I think that's good and practical. The new monitor of the Mark 3 is a blast. He is brilliant and sharp crack. A significant improvement to Mark 2. Just taken photos come color-fast over at the first assessment. Similar to a smaller package with my iMac monitor 27''nur. I can already vorbewerten pictures with stars with the shortcut key on the side. This makes the top of the monitor even more sense.
I shot most of the photos with a Canon 200mm f4 lens. The significantly enhanced autofocus is extremely fast and is seated perfectly accurate. One can, as with the 7D, preset and itself sets of focal areas in the camera menu. That may not carry much weight in portraits or other studio recordings. In nature scenes with sudden appearance of animal or sports photography This is vital if a technically excellent photo or just a good photo comes out. In this recording situations is significantly faster burst mode, which is only slightly below the recognized fast 7D, another crucial key to success. It is precisely at a high frame rate more likely to get even top photo at the right moment, for example, an animal in jump. Improvements have also been largely in black or white objects, eg cats etc .. A correct exposure succeed here often only in manual mode. The new metering appears (if you're not the object largely zooms into the picture box) a more balanced, much richer structure exposure of such extreme objects. If the exposure situation changes outside, one very highly detailed black and white areas can take pictures overexposed balanced even in automatic mode.
Even in twilight the very low noise Mark brought 3 significantly less noisy images or were significantly higher ISO values or short exposure times possible that are simply not possible with a Mark 2 and the not ideal here 7D so.
Who does not need this "Action", is still well served with the Mark 2. "Quiet" in studio environment I can make a signif. Picture quality growth does not really confirm. The new Ultra Resolution Camera rivals Nikon is really special. But with the very high resolution of the Canon 5D Mark 3 you save more than enough resolution and not the disadvantage huge image files and of course, having to process computationally intensive. The low noise at high ISO values decreases of course. This is physically not possible otherwise.
For movie quality I do not express myself as a filmmaker opportunity further. Others can do better. Very practical is now a marked red hot key for films on the back of bodysuits. The leveling of the sound in the Mark III menu is an important new feature.
Who wants to run Action, wildlife and sports photography at the highest level, wants top shoot images even in low light conditions, should have the Canon 5D Mark III. The operation (key assignment, raw conversion in the camera itself, etc.) is at the highest level. It goes without saying that one can ausreizen this camera only with top-quality lenses. These include in particular the 200mm telephoto Canon. Here come together quickly 5000-6000 Euro and more with such equipment. The just an Amatuer often not.
