I think the Voigts are lovely lenses with a signature look at wide apertures. Not ultra-crisp but crisper than, say, an f/1 Noctilux and at least as crisp as anyone's 50/1.2 or 85/1.2–1.4. Stopped down past f/2 they're also very sharp. They balance well on the Olympus E-M1, less so on other (smaller) m43 bodies. (I'd post some pics but I just did a file cleanup on my iPad in prep for an upgrade.)

Daves right about the signature look.
If you have to explain why you like the look of a voight you probably shouldn't buy one.
There not pixel peeping sharp but they just look . . . historic.
I bought the 35 and 50 for my M8 and never used them, or used them very little, but on the m43 cameras they come to life. It's just different and kind of grainy looking, kind of flat field, but pretty glow.
I'm still on the fence on buying the .95s Might get the 17.5, and 25 mostly for video, but since I have a 35 and 50 in m mount, I'll stop there. I love glass, really distinctive glass and it's hard to find lenses that aren't over sharp mechanical looking.
I have a few lenses that stand out and are unique. The old Harblei tilt shifts in Contax 645 and Canon mount. They work great on the 645, less so on a Canon but I'm going to convert the canon to mfthirds and see what shakes loose.
I also love the voights and the the really nicest lens for mfthirds is that slow Pansonic 100 to 300 4 to 5.6. It's just too slow for a lot of work, especially at night, but has the prettiest fall off of any lens for this system and really interesting compression.
IMO
