> I don’t understand people’s obsession with plastic vs metal lenses. It's an issue with perceived quality. So much of the inner workings of things have been replaced with plastic, usually not for the better. When you spend as much money on lenses these days, you don't expect them to cheap out on a small ring. Also, not all plastic is made equal. I have two lenses made in the last 20 years that have plastic that is starting to deteriorate and become sticky. It's a real shame as those lenses still work and do their job.
