Have you ever wondered why we have the 135mm focal length at all?
It’s not a nice round number like 50 or 200. In function, you could say it’s a bit long to be an all-rounder for portraiture where 75mm to 90mm is more comfortable. At the same time, you might complain that it’s a little short as a telephoto for travel, where 180mm to 210mm is more useful. So why do we have it?
First, the fact is that 135mm is standard repertoire. You will find it in every 35mm camera system since its introduction in 1960. The reason is simple: it’s extremely versatile. It works fine for portraits, it works very well for photojournalism and it’s excellent for travel and scenery.
