^^ That moose shot is impressively clean for ISO 12800!
I have to say, after shooting a thousand frames or so, I am really enjoying my downgrade to the 6D so far. Of all the features they decided to omit, I do no miss a thing. Even the perfectly placed reprogrammable dof-preview button on the mk III which I really came to appreciate has its equivalent on the 6D, only now I have to use my left index finger instead of my right ring finger to push and hold it down for those occations where I need to quickly shift from One Shot to AI Servo. It is slightly more fiddly. I even gave birds in flight a go (gulls and ducks, more parallel to the camera than perpendicular), and AF was spot on using the 100L. I also have the 50L, the 40mm pancake and the 35L, all of which required a little higher AF adjust values than they did on the mk III, using the fully automatic feature in FoCal Plus, though no more than +10, which I find comforting. The centre AF point has been highly accurate and reliable so far, on par with the double cross point on the mk III I would say, at least for casual shooting. I haven't tried anything really fast paced like people running towards me, race cars or jet fighters, and to be honest I don't think I will anytime soon. GPS really does drain the battery, and it is not something I will leave activated just in case it comes in handy. The -3 EV ability is very useful, this camera is truly is a low light low weight monster. Coming from the mk III, the 50L almost feels unbalanced on the 6D. With the pancake attached it feels like the worlds most competent point-and-shoot.
Wifi is proving useful, and the app is looking promising, though it is still extremely unpolished and needs a heck of a lot of work. I tried Chainfires DSLR Controller app which is far more sophisticated than Canons app offer, but I ran into some trouble and had to give it up temporarily. Using Canons app, I can make images pop up on the tablet 1-2 seconds after the shutter has closed (mind you it is a very reduced size, about 2 megapixels probably). I miss some more advanced options like a well made bulb mode and the ability to export images full size, amongst other things.
