Also, got to shoot an event with the 6d today - dyngus day...there was dancing..
Thanks for the pics, but the most important information for me is to get real life impressions about how the 6d feels in real life, stress shooting conditions where different camera bodies do make a difference.
Some good or bad shots alone don't mean anything, you can get them out of any half-decent dlsr, though the keeper rate, constraints by limited fps/af system & the trust into the gear is much more important. But the 6d seems to do ok - and it should, in 2013 even @€1800 this is pretty damn expensive for what it is.
Marsu, here are some more thoughts on it. IT's really not a bad little camera. I did not find the limited AF to be much of an issue, at least in my situation (that's where my 5d3 shines). I don't think anybody would be able to look at my images and be able to say, oh that ones obviously from the 6d. Colors are good, detail is good. From an IQ standpoint, I see no red flags at all. It's in the little things that make me wonder what to do. If i buy one it will be a compromise.
Weight - the 6d with 16-35 lens attached weighs about as much as my gripped 5d3 with no lens attached. I can see that being a huge plus for full day wedding coverage
IQ - the images do look pretty damn good. I can't say too much on keeper rates because I was overshooting with it (not because I didn't trust it - but because it was a retal body and i wanted to view as many images as i possibly could)
AF - that center point is pretty damn accurate and I couldn't find many lighting situations where the 6d said no, can't do it (without a flash attached!)
ISO - Very impressed with how well the 6d did at high ISO's. Files are very usable in the even at 12,800-25,600
Wifi- this is quite a neat feature. it may or may not be useful (doing some final tests on it today before packaging it up - actually right now I am doing it - with the camera set to never power off, just making sure i can still access the camera after my phone goes to sleep mode - also going to try the remote triggers again with the live view off) PS - tests done - the wifi does seem to just shut right off and you need to access both camera and phone to get it back going - so that limits what can be done a bit ---- and - if you turn the liveview off on the the phone ap, you can trigger off cam lights...)
no sync port - this would be a deal breaker if it were to be my main body.
AF - once the light gets dim the outer points become useless, not a deal breaker though because the center is solid
sync speed - I do wish it could sync at 1/200, but, I don't forsee this being too much of an issue
max shutter of 1/4000 - There will be situations where this will limit options, but again, not enough of an issue to be a deal breaker (this is another one of those if i didn't have a 5d3 as a primary body this would be a bigger issue)
read/write speeds - SD is slow!!!!! This may be the back breaker for me with it. At the small wedding yesterday, it was in big greenhouse and the light was shifting a lot, roaming clouds so it would get real bright real quick and if i fired a burst of 3-4 shots and went to get a quick preview to make sure i compensated, it would hang on the 'busy' screen for longer than I'd like.
battery life - battery does drain quite fast when wifi is enabled (note, I have no use for gps so i never tried using that). Battery life is fine without using wifi, but, with that on be careful!
Other thoughts. given the choice for backup bodies, at regular prices I can't see shelling out 3k when the 6d performs as well as I have witnessed. If i can find a used or refurb 5d3 for around $2500, then the choice becomes harder. this also depends on what deals pop up for either camera. If I see another deal for a 6d at $1800, it will be hard to say no
Why would anyone buy a 6D when a refurb 5D3 is only a few bucks more?
My answer - if you are on a 5d2 and looking to upgrade, yeah, snag the 5d3. I see the 6d as filling two niches - those looking to upgrade from crop to FF and those who are on a 5d3 and are looking to upgrade their backup. I would recommend the 6d for those running the 5d3 5d2 combo - IQ is just as good as mk2 but its high ISO abilities make the 6d a much better backup than a 5d2.
As to whether the 6d is the right solution for you? It really depends on what you shoot. If your in lots of controlled light and shoot between ISO 100-800 mostly, then the 5d2 is probably the better value for you. If your shooting weddings though, the 6d performs really well at high ISO's, this beats out the 5d2 and then some. If you shoot sports, the 6d won't be what you need - FPS is not that high and the read/write speeds will leave you waiting more than shooting.
back to the question of, is the 6d the answer? I am still debating this myself. Not sure which way I will go. It will depend on a lot of things like how many more weddings will I book this year, what happens with deals and rebates, and what happens with the used/refurb market. If i were to see a 5d3 refurb for $2400 and actually had the $2400 in my account, then there I go! But, I have noticed that those refurbs tend to sell quickly. And used ones are still pricey - B&H had one up a few weeks back for $2800. I will say this though, after a hands on with the 6d, it does make my decision harder because it is quite a capable little body.
