k-50 lens cap

Hello everyone.
I have a question regarding lens caps for a k-50. I just lost the cap for my da l 18-55,50-200wr lens. How do I find out what replacement cap to purchase? Since I'm fairly new to the photography world I assumed the cap from my 18-55mm WR f3.5-5.6 would fit it but it does not.
Any advice would be appreciated.

The DA L 18-55mm (non WR) and the WR version actually have different caps and filter sizes. The WR version is smaller.

You'll want the O-LC52 (or any generic 52mm cap) for the 18-55mm, and O-LC49 (or any generic 49mm cap) for the 50-200mm WR.

If you want the official Pentax cap, Adam gave you the model number. But any generic cap will work as long as it is the proper size. Lens caps are sized by the filter thread of the lens. This is marked on the lens someplace usually with a little symbol that looks like a zero with a line through it.

Go to "Deal Extreme" and buy the caps with center pinch. IMHO, functionally, they are better than stock Pentax caps.

Since they are so inexpensive, buy some spares too.

Example: 52mm lens cap.
