Personally I dig this weird little fella
It’s an old Soviet 16mm film projector lens adapted to a different vintage lens’s helicoid then adapted to Micro 4/3.
It’s a 50mm f/1.2 lens and it takes some weird photos. It’s not perfect (especially if the area is well lit) but it takes some interesting photos with a little practice.
Edit: And being a lens made for 16mm film it takes pictures just like a normal micro 4/3 50mm lens would.
the Sony Zeiss 55mm f/1.8, (that one with the concave front element), is my one desert-island lens, for sure. Me developing my own style went hand-in-hand with getting to know it better for a few years.
I used to love using “weird” and specialist lenses, but it’s so versatile, it killed my trying all kinds of cheap/vintage glass- since getting the Zeiss, everything else just stays in the bag.
