+1 for the Op Tech rear caps--the dual ones are really handy for small lenses. Cheap ebay ones have been a mixed bag for me; I figured in the long run I'm better off spending a bit extra for something decent--or else I'll need to start buying crappy lenses to match the caps.

These lens/body caps are great, cheap, and they lock together. Just bought a couple of sets and I'm really happy with them. Lens caps have proven to be a bit of a disposable commodity for me.

Yup, thanks!

**hjoseph7** · 01-28-2015, 05:23 PM

I only buy the manufacturer's original lens cap at B&H or on eBay if I can find it.

The rear cap with the Oreo Cookie design on it is from Fotodiox. They are my favorite non-Pentax caps.

**forest_bear59** · 01-29-2015, 04:35 AM

From Amazon in Germany they want a shameless 8,90€ for each

.

Ok, maybe Ebay could help ....

thank you - glad I am not the only one thinking that the design looked like an Oreo.....

Oreo was my first though too, but improved with an 'open' arrow showing you how to access the white filling. It's maybe worth ordering several backups for when you absent-mindedly take bites out of them.

I ordered a package of 10 rear lens caps from this company on January 27th. I was somewhat skeptical, mostly because it was from an off-shore company. (China) They arrived today, 8 days after I placed the order! They are SUPERB! Twist-on caps with a flange that lock in place nice and firm, exactly as I wanted them to do. Marked "Pentax," and for all I know, they are indeed OEM. They look like it.

A grand total of $9.72, including shipping! I'm going to order 10 more. What a pleasure to circular file those, old, loose-fitting POS caps I've been dealing with for far too long!

**jatrax** · 02-04-2015, 06:44 PM

I ordered some as well, but I got mine through Amazon they arrived yesterday. Tested all 15 I ordered and every one works perfectly.

Took great pleasure in dumping some old caps in the trash.

They even have a nice arrow and the word "open" on them for us old guys that forget how

When I got my K-x some years ago, the DAL 18-55 kit lens that came with it came with a soft plastic rear cap that simply pushed on/pulled off. It actually does work, but seemed awfully cheap. I found a very good use for it, though. I have a few M42 lenses but only one M42>K adapter. I put the soft plastic rear cap on my lens with the adapter, and I can squeeze it just enough to easily unscrew the adapter when I want it for another lens. (Can't do that with the rigid plastic end caps.)

I bought those from the same seller in 2012. There are very minor differences between those and the OEM Pentax caps - the textured areas are different, the mold release marks aren't the same and the lettering is quite as "sharp". Most likely casts and molds were made from the originals. The counterfeit caps are much more snug - I can't remove them easily single handed (which is what you wanted).

They do the job and are practically indistinguishable from the "real" thing. A great value for the money.

I only use Pentax branded rear caps on all my lenses - Pentax, Sigma, Tamron. Easy to swap from one lens to another without thought. Always a snug, tight fit on the lens bayonet, unlike Tamron and Sigma rear caps. The original Sigma and Tamron caps go in the len box in case I decide to sell the lens sometime. IMO Pentax rear caps are worth the extra money.

Another use for those - if you're doing extreme macro using reversed lenses, you can cut the end off and turn it into a "hood" for the exposed base of the reversed lens.

Op Tech rear caps are a bit expensive @ $16 from B&H, however they have a rubber seal that presses against the mount to keep out dust, and it also holds the cap on gently but securely. They aren't as convenient as genuine Pentax rear covers because the latter can be put on without aligning the cap with the red-dot on the lens, whereas the Op Tech there's a ridge (mark it with a little white paint) that must be lined up with the lens' red-dot.

These seem like a really good idea to me, at least for WR lenses. My thinking is that if you're packing light for some kind of wilderness adventure, and you have a WR lens in a soft lens pouch, having a rear cap that seals might save it if you end up getting
dunked or drenched. Without this, your WR lens is only WR while it's on your camera, or in a waterproof bag.

I'll probably pick up a couple of them eventually.
