Can we get a 24-70 1.8 please!! That would be amazeballs!! 35 doesn't have enough reach sometimes but 100 seems way more than I would ever use for video.

I finally got around to looking at the Sigma Global site for all the nitty gritty details.

Just reading this gets me excited.
The diameter of the diaphragm is the second-largest in the SIGMA lens lineup after that of the SIGMA 200-500mm F2.8 /400-1000mm F5.6 EX DG

Definitely tuned for IQ at the long end. And it looks pretty good.

18-35A for comparison

So I assume those MTF charts show the 50-100 actually better than the 18-35? That would be pretty incredible since the 18-35 is one of the sharpest APS-C zooms ever made.

Seem to be pretty similar in the long end. However, the wide end of the 50-100 appears to be a bit softer than the 18-35 (which is remarkably consistent in its sharpness).
