I'm currently reviewing two EF-M mount lenses from third party manufacturers: Tamron 18-200 VC and Rokinon 12mm f/2. They are both very good lenses: the Tamron does a little bit of everything quite well. But the little Rokinon (manual everything) is a true treat. It is basically a better version of the 14mm f/2.8: less distortion, similar sharpness, and can use traditional filters. I LOVE it! The only thing holding it back is the basic limitations of a crop sensor (as compared to a FF sensor).
My full reviews will be live in the next couple of weeks.
I'm glad to hear of further development for the M. It definitely has limitations, but it produces surprisingly good images. I actually used a 60D for a recent review of a crop sensor lens and was surprised by how much less "clean" the images were compared to the EOS M images. I haven't used a 70D/7DII yet, but I suspect the images from the M will be closer to the 70D than the 60D (I do anticipate the 70D/7DII having the best IQ of the three).
good to hear!
you are probably gonna make me spend money aren't you?
with these reviews
but what i really want to see canon bring out is an EF-M 15-85 IS that will be killer without all the compromise of a super zoom especially if it is as good as the 11-22 then the 12mm rokinon would fill in the wider end quite nicely.
