I have this lens and like it. As others have posted , it is either too long or too short.
The question is where did the 135 mm come from. It is a holdover from the RF days.
The rangefinder on the Leicas, Canons, and Zeiss would only go to 135 . Anything longer required some sort of reflex system, Leitz Visoflex for example.
Sorry if this post is so basic but I see lots of people on this site who have to get their knowledge here instead of in a Camera store due to the dxxxxxx takeover.
