There are some metal caps for M42 lens. I am curious if these metal caps will provide a better protection than the plastic lens caps. Anyone has experince? _________________ https://www.instagram.com/_lens_fever/

If you have a habit of dropping your lenses on spikes or hitting them with sharp objects that would penetrate plastic caps, then certainly metal is better for protection. On the other hand plastic caps may be able to absorb shocks better (possibly breaking the cap in the process) while metal caps, especially screw-on ones, will transmit the impact to the lens.
But in my opinion if the safety of your lens comes down to the material of the lens cap, you might be better off considering a different way to handle the lenses. =)
(For lenses actually in use, a lens hood is good protection. Actually the same thing kind of applies there for rubber/plastic vs metal, but I prefer metal hoods for looks.) |

+1 I have a few metal caps, third party and genuine one. I like plastic better, actually current Chinese made ones what is widely available on Ebay I think best ones from all. _________________ -------------------------------

A stiff rubber hood (NOT the collapsible type!) is definitely the way to go if you want impact protection for a lens.
Plastic types are a close second, but you have to replace them after they have taken a hit. Thin metal hoods would come in third, as they would still help you out in diagonal impacts, just not as much for straight-on hits.
Metal lens caps may protect the glass the best, but they will transfer the full impact forces into the lens body. Some lenses may be tough enough to handle this, but not all of them are. Plastic lens caps may be a bit better than metal in this regard, but in any sort of diagonal impact, a plastic lens cap will just snap off, leaving the edge of your filter threads to absorb the impact instead. _________________ Sigma DP1, Nikon D40 (hers ), Polaroid x530, Pentax P30t, Pentax P50, (P30t/P50 K-A to Nikon F body mount conversion)

I am using old leather case for each lenses and caps , nothing to worry about just simple throw all things into my bag pack . Old lens cases made by Japanese or Germans best lens protectors what I known in transfer. In storage I use cheap or used filters to protect lenses. _________________ -------------------------------

The only metal caps I have are 72mm screw-in Nikon caps, they fit some of the wide-angles.

Thanks all. I have some collapsible rubber but I am not satisfy with their quality. I will try stiff rubber hood if I can find one. _________________ https://www.instagram.com/_lens_fever/
