Will Sigma ever release the 18-50mm F2.8 zoom for EF-M?

Re: Yes, but perhaps no. Your guess is as good as mine.

Heh. So Canon can do corrections for Sigma lenses after all. Come on Sigma, give us the F2.8 zoom!

It's not Canon doing corrections for Sigma lenses - that would imply that Canon had studied them, worked out the aberration, colour and distortion corrections they required and were encouraging people to use Sigma rather than Canon lenses. Sigma have reverse engineered their latest lenses to give the required data to Canon's in-camera correction engine. Not surprising when you remember the reputation they used to get for strange concentric dark and light circles with peripheral illumination correction enabled in camera.

I should have said Canon will accept and use the correction info coming from the lens after all.

There was earlier speculation that Canon blocked correction info from 3rd party lenses and that could be the reason Sigma hadn't released the 18-50 F2.8 for EF-M, since it needs more correction than the primes.

Maybe if enough of us pestered Sigma, they might decide there's sufficient demand to make it worth their while.

Unless they've prototyped it and found there are issues which can't be resolved on Canon's correction engine...

Or decided it will hit the sale of the primes too much (the most likely answer IMO, although two of them are just outside the range of the zoom).
