Should I get the 17-55mm IS USM lens?

I wouldn't. That Canon lens is an aging lens, good five years ago when the options were fewer and sensors less dense. If you can live with the risk of focus inconsistency associated with Sigma and the absence of IS, I'd steer you to the Sigma 18-35/f1.8. Sharper at f/1.8 than the Canon lens at f/2.8. Mine suffers from focus inconsistency on 6x0D bodies, but I keep it because the optics are so exceptional. I'd then round off the top end with the new, $125 50/1.8 STM lens.

Alternatively, you can consider the 18-55STM kit lens, backed up by two fast primes, the 50 STM and the 35IS.

The 17-55 is certainly not a dated lens and is quite sharp enough for the 7d2, and certainly the 60d. The lack of IS on an all-purpose zoom, such as the Sigma, is a nonstarter. Moreover, while I am still considering the very sharp Sigma 18-35, the posts here indicate focus issues that can be a pain in the neck to address. No such problems with the 17-55. The 18-35 seems like a specialty lens to me, rather than a general purpose standard zoom.

Fine, go ahead and buy it. I'd hate to see what it looks like on those new 24MP APSC sensors. Say what you want about the Sigma. One thing is clear: optically it shreds the Canon. I, myself, mount it on the M, and poof! all focus issues vanish. Ciao.

Well, of course, I already own a 17-55 and have for years. By the way, asiide from the size and weight disparity, ithe 17-55 performs quite well on the Sony A6000 (with adapter), which is a 24 megapixel sensor. As far as Canon APSC bodies are concerned, the recently introduced top-of-the-line 7d mark ii is only 20 megapixels. So I don't see Canon jumping to a 24 megapixel APSC sensor anytime soon, not that such a move would in any way obsolete the 17-55. It is a good all-around standard zoom.

Really? You don't see 24MP APS-C sensors on Canon cameras any time soon?
