Have to agree, the Sigma 24-35 f/2 is about as close as you'll get. Honestly, I think its as sharp if not sharper than my Sigma 18-35mm.

How is a 24-35mm close to the field of view you get from an 18-35 on APS-C of 27-53mm? Have you ever looked through a lens and seen the difference between 24 and 28mm settings on a zoom? It's quite a big difference.

Added to that, with the small APS-C sensor the f1.8 looks like f2.8 on full frame, a full stop away from f2.

In other words, 24-35 on FF has little in common with a Sigma 18-35 f1.8 , except for people who only see numbers but don't think.

If you don't understand all this, why not post a question about equivalence on Open Talk. They love equivalence there, there are people who will write 1000 words to this question.

Some people think to much and dont see the numbers......

The OP was after a fast sharp lens, this is the Sigma 24-35mm f/2, no?????

As for this focal length not being close - To me 27-53 is close enough to 24-35mm.... For someone who only sees numbers aparently, id seem crazy,.....least I can think.....
