Overview

Every working photographer knows the quiet anxiety of reaching into a bag and finding a lens cap has wandered off mid-shoot. The Pentax 31522 is the manufacturer's own answer for DA 18-55mm II owners — a properly-fitted 52mm front cap that protects your front element during transport, between setups, and through the rough handling that gear-intensive days demand. It's not a glamorous piece of kit, but a well-fitting lens cap is invisible when it works and painfully obvious when it doesn't.

Built to OEM tolerances, the cap seats with a definitive click onto the DA 18-55mm II's filter thread, meaning no accidental drops in a camera bag or jacket pocket. The center-pinch release keeps one hand free — practical when you're managing a camera strap, a reflector, and a client at the same time. Lightweight enough to forget you're carrying it, durable enough for daily use, it's the kind of essential accessory worth having a spare of in every bag you shoot with.

Frequently Asked Questions

This cap is Pentax's own OEM part (model 31522), machined to the exact tolerances of the DA 18-55mm II front element housing. Third-party 52mm caps will technically fit but may seat less securely — if you're swapping lenses quickly on a shoot, the factory fit is noticeably more positive.
The 31522 uses a center-pinch design, so you can remove it single-handed without removing your lens hood — a real convenience during run-and-gun shooting when you're pulling the camera up fast.
Pentax lists the primary compatibility as the DA 18-55mm II. The filter thread diameter is the same 52mm on the WR variant, so it will physically fit, but confirm your specific lens before ordering if exact OEM fitment matters to you.
The cap is lightweight ABS plastic — it's not going to crack easily, but it's also not intended for heavy-duty abuse. Treat it as a lens protector, not a punching bag, and it'll outlast the lens.
No — the center-pinch cap seats directly onto the filter thread rim. If you have a filter installed, you'd need a cap that fits over the filter's outer diameter, not this one.
