p.hawksIf it is for an a7, check out the voigtlander 40mm f1.4. I believe you want the multicoated version as the single coated is supposed to be better for B&W photography. I really like the 40mm focal length on my 5d, so I have been looking at this lens (and will buy it when I sell my 5d). If you want AF, the zeiss 35mm f2.8 appears to be pretty popular and not too expensive.
I dont have an adapter, so I was looking at mainly sticking to rokinon. The zeiss caught my interest though.
Would you happen to have any videos of those lenses in action? Preferably sports?
