I'm still on a 5DII and need a reason to upgrade
Ok seriously no, I do want a 5D3, I've missed many worthy shots with the AF, and I shoot too many indoor events/low light subjects and weddings to keep risking more with it. Cool thing is though, I bought my 5D used, and I've found the used value here hasn't dropped, and I will be able to sell it for next to no loss if I do it right~
The 6D can out perform the 5D3 in low light.
Generally a horribly generalized statement. But I will say it does perform better in low light if you are only using the center point. That being said, every other aspect of the AF system is significantly weaker than the 5D3.
I think you've nailed it here. There are two factors that do support the general statement, but others that don't. The two factors that support the statement are:
- Center point on the 6D has the highest sensitivity of any Canon body (to -3EV).
6D has slightly better high ISO performance and is slightly cleaner in the shadow areas.
But there the 6D's advantages end. If you are tracking moving subjects in low light, the far more robust AF of the 5DIII is going to produce a higher keeper rate.
My article on why I chose a 6D over a 5DIII has been the most popular I have ever written and has been viewed many tens of thousands of times. There is plenty of anecdotal evidence in this thread to support many of my conclusions, but my purpose is not to put down the 5DIII. It is, perhaps, the best all around camera that Canon has ever produced. But Canon made a curious decision when producing the 6D. There are areas where it is clearly the "lower rent" version of its big brother, and yet there are also areas where it excels and even surpasses the 5D3. Canon has not created a perfectly clear hierarchy of "good, better, best", but has rather produced camera options that are really more about WHAT you shoot or your style of shooting.
For some the 6D is a fabulous choice. For others the 5DIII is the only choice (unless you are willing to go into 1DX territory). It's all about your needs.
