Promaster 4323 Pentax K 後蓋鏡頭蓋

It snapped perfectly onto my Pentax K lens, fitting snugly right out of the box. The hard plastic feels solid enough to keep the rear element safe from dust and scratches during storage.

Dropped my lens bag on the driveway and the rear cap still fit perfectly after the impact, so it’s definitely tougher than a standard plastic cap. The snug lock onto the K-mount is reassuring, and it keeps dust out even in my dusty camera bag.

The fit on my Pentax K-mount lens is snug and secure—no wobble at all when it's snapped on. It's a simple piece of plastic, but it does exactly what it's supposed to do and feels sturdy enough to protect the rear element during storage.
