The 28mm f2.8 Distagon and the 50 1.4 Planar in C/Y mount provide wonderful IQ on A7/r, but I wonder about the 35-70 zoom – is anybody using it?
I've been thinking it would be handy to have a zoom for when I want to carry only one lens, and the old reviews say this zoom's IQ was almost the same as the primes. But I also read that the unusual one-ring adjustment feature might create a vacuum and drag dust into the camera/lens chamber?
So how about IQ and dust? Any experience? I know it's a big one – does it feel clumsy, or does it handle pretty well?
PS, images from the C/Y Zeiss 28 and 50 are impressive in their almost 3D quality and their fine tonal gradations – and they aren't as super-contrasty the new Sony Zeiss lenses. I'll try to find time for a longer post about them….
