There are issues about how we talk about the focal length of lenses that often lead to confusion - see this question for example. I recently read, and agree with “35mm Equivalents”: A Plea For Clarity which suggests a way forward:
Basically when talking about lenses for cropped sensor cameras, you give 2 numbers - the actual focal length and the 35mm equivalent focal length. But you can shrink it to, for example (using APS-C), 50mm (80e) - the "e" is short for "equivalent". Which, to me, is nice and succinct.
Obviously there are times where using this would be more confusing than not - say discussing Canon EF lenses without a particular body in mind - but a lot of the time there would be only one crop factor to think about - Canon EF-S lenses, Nikon DX lenses, any 4/3 or u4/3 lens ...
I'm not suggesting we should enforce the use of this shorthand, but if quite a few of us started to use it, it could become a de facto standard on this site at least. We could set up a question to explain the term (whether on photo.SE or meta.photo.SE) and link to the question when we use the shorthand - eg. 50mm (80e).
So do you think this is an idea we should try and encourage? Or is it just going to be too confusing?
