It's a Zeiss lens and at f/2.8, it should be very sharp at that aperture, if not please dun even put the Zeiss blue logo on the lens ya? Most of us go legacy as we need shallower DOF and wider aperture than the f/2.8. It's quite limited what we can achieve on the FE35/2.8.
The FE 55/1.8 is another matter, seriously worth getting if U do not already own a great 50mm legacy lens.
Yeah, its a expensive for a 35mm, but being a Zeiss, its in a class of its own. It is still a great lens, although we are spoilt by the legacy lens, Lol.

Anyway, I'm still deciding whether to keep this lens once I got the CV 35/1.4 or ZM 35/2.
