Well, it's been over 10 years since I last used a 45 camera. Now I am going to get my hands on a new toy, a handheld 45 camera, in a few weeks. I have to choose a lens for it and I will use the camera mostly for portrait in natural light. The factory recommeds that my lens choice should be in 120mm-150mm range with f/5.6 for easy focusing and the lens should not be super heavy.
So I would like to have some ideas as I have no experiences in handheld 45 cameras.
