what is the inner diameter of this cap? can it fit on Leica 50mm f1.4 Summilux 1st version? thanks
I was interested in this cap but there's quite a size discrepancy between the advertised size and your 8.3 cm. The ad shows that it is 5 inches, which is 12.75 cm. Assuming that 12.75 cm is the overall size, that would make the material just over 2 cm thick (7/8"). I hope Helen sees this and can clear this up.
