Just because "popular usage" may not appear in a particular dictionary
does not constitute "misuse".

If you speak of a prime lens to photographers, they know what you're
talking about.

The problem is, they may not. I do sometimes have occasion to mention "prime
lens" and I assure you I use it correctly. People who think it means fixed
focal length will, therefore, not understand what I am saying.
