So why do we use 50mm as a standard? Well, it doesn’t really matter, but the maths does explain why Tamron is touting this unusual focal length as a standard for full-frame users. The company isn’t the first, either, as Pentax offers a rather nice 43mm f/1.9, and has done for some time. What makes the Tamron example special, in my eyes at least, is that it’s a bit faster than the Pentax and, more importantly, it’s a fixed-focal-length lens from a company that has been obsessed with producing zooms for as long as I can remember.
