100% crops here: http://blog.kurtlawson.com/  Here's a full size pic at 16mm. How does this compare to other copies out there? http://kurtlawson.com/ars/111209/IMG_0073.jpg 1/500, f/8 ISO 100 -K • http://www.kurtlawson.com

Center sharpness peaks somewhere between f/5.6 and f/8 depending on focal length.

I hope this can be corrected with DPP, another way you can't crop this picture at all.. I could only try the 24-105 a few shots and this zoom had also significant CA. Marc

If you want to see bad CA try the 85f1.2 the 16-35 blows that away,There is not a lot of CA in those images.

I am just talking about wide angles lens at about same price, not 85mm or anything else .. Impossible to crop this picture, even near the center of his picture, you get this at F/8  .... full blue on the left and full red on the right of the tree...Anyway, I don't know anything with zooms, so maybe this is completly normal  I only have a 70-300DO which doesn't have any CA, but I almost never use it ... sorry to have disturb this subject  ...Marc

Neither can do what the other can do (well, the zoom can do 21mm, but not as sharp.) I would consider the 24mm f/1.4 II complementary as well. The OP would have to get quite a few primes to cover that range. I hear the 24 TS-E II is quite the amazing lens too.
