As I get older I get a bit more conservative... The result is I really don't ever use our Arri/zeiss UltraPrime 12mm.
If there is anyone with an Ultra Prime 14mm who would like to go wider ....maybe a swap with a bit of cash? Or if you have a 20,28,40 we could perhaps do something as well.
Details: good condition rarely used (never lived with a hire company) imperial scale and UK based.. and I have a nice case for it.
