Spending a day with this lens and A7r, shooting in relatively dark and bad light location, mostly iso6400 and f2.8.

Nice concert photos. Though it is not abundantly clear that the tilt function was a factor (I am not an expert on tilt lenses though!)

Seems to work very well with A7r.
I have the M 85 f2 and the M 120 2.8 with an A7. I lke them especially the 85 . They have unfortunately some CA . Is it the same with this 100 f2.8 ?

CA is very little, mostly unnoticeable, but depends on the scene.

M85/2 and M120/2.8 is also good, and I think M85/2 has more CA than the M100.

My choice of M100 is also size, reach and weight.
With a tilt adapter, it covers also DOF in diagonal compositions.
