Guy,
I just reviewed your big bronco crops. Thanks for doing this.
Very similar results to what we saw with the infinity tests (first page). Basically, the FE 24-70GM performed best at the wider range (24-40mm). From 50-70mm is still very good but there is a slight resolution penalty.
70mm seems to be its achilles heel and needs f/3.2 or f/4 for match the excellent wide range performance in the center and f/8 for the very corners.
From my tests, lensrentals and yours, I think the 24-70GM is a very strong performer wide open to the very corners (with the exception of 70mm) but the sweet spot for optimum center micro contrast and very good corners is f/5.6. At f/8 it\'s almost as good as the best primes I\'ve tested.
The lens rendering and bokeh quality is very special and something I\'ve never seen from a mid-range zoom. Heck, it draws better than many native primes.
Agree Fred between the 3 of us we put the pieces to this puzzle together nicely. I\'m astonished at the 24mm setting you could almost shoot this wide open across the field. That\'s amazing for a zoom and the 28 and 35 are just so strong. 50 is very good as well but again I think I would prefer the Loxia 50 but I don\'t want anyone to get that comment wrong this is just me being very anal about this stuff and Fred seems the same way . 50 is very good on this zoom. On center this lens is killer at every focal length. I also agree on the 70 as it really jumped big time from 2.8 to F4 in center and corners need to be stopped down. Even though it very good at these setting its the weaker focal length. For me I would be reaching for my GM 85 here anyway. Interesting the shot at 70mm at 4.5 of the overlook of that mansion. 1200 square feet on sale for 2.2 million which is pretty good for Sedona anyway that image is very crisp on building and the mountains look dang sharp to in the background.
But the lens rendering really makes this lens very special. Totally agree I never seen anything like this in a zoom for that alone it\'s worth every cent we pay for it. Some primes are really going to have a hard time keeping up with this zoom. I do want my Loxia 50 back and not sure I need anything else, unless I could find cheap Leica 28 R version II . Anyway great job Fred on your end I do love how you do the infinity postings and I find that very useful to me. Next up GM 85 and I will be starting that soon. I do hope all of this data dump has helped some folks make some smart but decisions either way.
