My late father was a photography enthusiast throughout his life, and I came across his camera gear today which includes some old soviet lenses (Jupiter-37A, Mir-10B). I'm still getting my feet wet again with photography - have a X-T5 body, and I've got an m42 to x-mount adapter on the way. Do I also need a speed booster to get the full value of these lenses, and if so, any reccs?
