According to my interpretation of DXO's lens tests and The Digital Pictures lens tests http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=355&Camera=453&Sample=0&FLI=5&API=2&LensComp=675&CameraComp=474&SampleComp=0&FLIComp=5&APIComp=1, a FF camera with a 24-105mm lens should have much sharper IQ than a crop with a 15-85mm. Is this the case?

I'm still undecided about getting a 6d for landscapes. I'd keep my 7d for action and reach. If the 24-105mm is much better on a FF than the 15-85mm is on a crop, it make the decision easy for me.

Thank you!

there is something to be said about about what dxo are showing when a 24-105 IS loses 9 mpxl on a 5dii and goes to 12 MPix.  I'll assume that L zoom lens performs similarly on 5d3.  That lens GOT CRUSHED according to their tests.  Instead, I'll use $1800 worth of glass -- the 100L plus sigma 35 f1.4 on a 12.8 MPXL 5dc -  and I'll get about the same 12 MPix Solution -  for about the same dollars  - but access to much more powerful f1.4 and f2.8.

Look at the new 24-70 F4 L IS for $1500 at dxo.  It only gets 13 MPix on 5dii.

Before I was saying -- $800 or less F4 zooms are Meh on FF

Now I'm saying $1500 or less F4 zooms are Meh on FF.  As I've been saying -- Go with great primes on FF to see advantage.
