Sigma rear lens caps...


Well-Known Member
Hi colleagues,

I've been looking for rear lens caps for my SIGMA lenses and adapters but without any success.

Does anybody know any place where to buy them?.

Thanks in advance.

I would look on ebay...there is always a hong kong based company that can manufacture these items for about $4.00....also you can look for the clear white slip on covers on ebay...sort-of a one size fits many...

Thanks Tony!.

After Uwe's advice, I ordered a bunch of Pentax-K caps, they will doble as SIGMAs, I've got a lot of K lenses without rear cap.

(I didn't find any Sigma)



Some Pentax lens cap do not work as well

I tried some Pentax caps and they fit, but do not secure (loose to the extent that they turn and fall off). I ended up buying mine direct from Sigma (and ordered the newer, center pinch front caps as well). Got the caps in less than a week - very fast delivery.


PS My order was with Sigma USA



it all depends of the manufacturer. I have Pentax rear caps from different sellers and some fit perfectly, some loosen over the time.

But to be sure, I agree. Buy the Sigma originals - or if they are too expensive, buy a broken Sigma lens at ebay and you get front and rear cap with it.

To save mailing costs, you can even tell the seller just to send the caps :z04_9856:
