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.

What's your thoughts on this (assuming that it's everything and more) vs. the Canon 85 1.8?

Totally different tool. The 85 is positively tiny compared to this 1,5 kg beast. Plus of course it's three to four times cheaper.

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).
