Enjoying the 24mm then? Heh he heh :-)
I'll say one thing for Sigma and Tamron caps: They're annoying, but
they lock up damn well. I've bought 3rd party rear caps that won't
latch on to Sigma lenses (but work OK on Pentax branded ones), so
there's a 1/4mm difference in there somewhere that annoys the hell out
of me. In the end, I just use Sigma caps for my Sigma lenses and curse
while putting them on.
