DA 15mm Ltd. Alternative Lens Cap


I'm looking for a 49mm lens cap (specifically one made by Pentax) alternative to the screw-on one on my DA15 for ease of use, and I had a few questions about B&H's offerings. I found two different lens caps available:

1) a pinch-type cap: Pentax 49mm Snap-On Lens Cap 31526 B&H Photo Video

2) a standard snap-on cap: Pentax 49mm Snap-On Lens Cap 31491 B&H Photo Video

Firstly, I wanted to know if the pinch cap (which is the same type as the caps for my kit lenses) is as pictured. As far as I could tell from looking around the web, no one else offers this style of pinch cap from Pentax in the 49mm size (not even from the official Pentax web store), and I don't even know what lens from Pentax ships with one of these. So, if they really do make these types of caps in the 49mm size, then that's great.

The second thing I was wondering was whether the pinch cap would be better for the DA15 since the retracted hood still protrudes slightly on the top and bottom edge, or if the other standard snap-on cap is still just as easy to get on and off this specific lens. Also, I'm just slightly concerned about whether or not these two caps might scratch or touch the front element of the lens, so if you have any info on that, I would appreciate it.

Thanks for all the help!

I would suggest using the replacement cap for the 15mm lens and not risking trying an alternative. This Pentax Lens Cap is specifically designed for the smc PENTAX DA 15mm f/4 ED AL Limited Lens.

Since the lens accepts standard filters, a traditional cap may also work. I asked a Store Manager to call up the pinch cap and he said it looks as it does on our site.

Thanks for confirming that about the pinch cap.

I actually still have the original cap that came with the lens, so I don't need a replacement. Rather, I'm interested in finding a snap on cap to use since the screw on cap is sometimes a bit inconvenient. I've read about other people doing this on these forums (and I've done a similar thing with the small screw on cap on my DA 40). I'll continue to look in the rest of the forums to see what other people have said about this.

Thanks again for the help.
