If all you shoot is your family and it's still portraiture, the 6D will be SUPERIOR to the 5D3 for most scenarios. Not all, but most.
Oh my, I won't get into an argument with you, but this is sooooo unreasonable - with a faster lens like f2.8 which you'll often use for portraiture, the 6d's center point is non-cross, meaning you carefully have to focus on an appropriate contrast part or you'll get af (micro)-misses. The bit of 6d less noise (if any) certainly doesn't compensate for that.
Agreed. It is these kinds of comments, that the 6D is superior to the 5D III "for most scenarios", that is so wrong. The 6D is superior "technically, in a FEW areas", but in EVERY respect and in every scenario, the 5D III is the superior camera that will perform superiorly and produce better images.
Definitely agreed regarding actually making images. I loved my 5d3 for the fact that it made getting the shot easier for me. I am definitely getting more misses and need to be much more mindful of the AF. Did a 4 hour shoot on Friday that would have definitely been easier with the 5D.
Results based on glass used:
24II was off a lot. Not completely. But definitely was not focusing critically most of the time. Yes, it has been run through FoCal with the new body.
24-70II was having a hard time capturing focus at all but was decent when it finally hit.
70-200II worked perfectly. But it was also solely used in the outdoor portion of the event
50L was performed on par with how it was on the 5D just based on memory (surprisingly).
8-15 fine as expected just due to the type of lens
The 5D? You mean the 5D classic? I find that difficult to believe.
My apologies for the ambiguity. I'm referring to the 5d3. For all future conversations, I will never be referring to prior iterations of the 5D unless specifically stated.
Ok just refer to it as the 5D3.
I'm not saying there won't be more misses with the 6D in good light vs. the 5D3, especially with certain lenses such as the 70-200 f/2.8 ii. But that's why the 5D3 costs more, because it is faster processing/shooting, has a superior AF system in good light, and that system is tuned for, and meant specifically to get the most focus accuracy for three of Canon's newest (and fastest AF'ing) lenses...the 24-70 f/2.8 ii, the 70-200 f/2.8 ii, and the 300mm f/2.8 ii (as well as the other series 2 big whites). However, for all other lenses, the precision advantage will be less so. Still there, but less so. And that's in good light. I admit most professional application events are in good light.
However, most low light wildlife shooting, low light people shooting, and of course landscape, are vastly better served by the 6D's center point, and its IQ specifically in the ISO range that these shots would employ.
So I state categorically NO, the 5D3 is NOT better in "every scenario"
than the 6D. Anyone who says otherwise is a biased 5D3 fanboy, in my book.
