Originally posted by SSGGeezer I just found 20 for 14.99 on E bay, they look like they may be OK. If I go for it do you want a few? Generic and probably just pop on, not rotate. Let me know and it may encourage me to buy them.
Nah, thanks. I saw those. I want twist on. I also find that the genuine Pentax caps work the best for staying on, at least on the M42 to PK adapters. All my Sigma lenses have genuine Sigma caps, which work the best on them. I have one Tamron lens, with a genuine Tamron cap, and it works perfectly on it. Like someone else mentioned, even though the PK mount is ubiquitous, the caps seem to work best on each brand of lens, and not sow well on other brands.
And I don't see myself buying that many lenses over the next 10 or 20 years. Although LBA is incurable, one reaches a point where all the focal lengths are covered, for the type of shooting one does, so I doubt I will be acquiring many more.
