Please help with Lens info....

Well, I'm having fun taking pics with these manual lenses but I'm having a heck of a time trying to find front caps for them. Unfortunately I'm missing one rear cap (not a big deal) and no caps for the M50 and M35. The online advice is to look for the 0 with a line through it, for correct sizing. However, these lenses don't have that marking on them. Therefore, I'm not sure what size to order. I am looking on camerafitters.com and I think they will carry what I need IF I can figure out the size.

Any ideas?

Ebay! They cost a couple of dollars including the postage I think.

Three ideas:

1. Look in the Lens database.Pentax Reviews - Pentax Lens Reviews & Pentax Lens Database

2. Measure it with a ruler.

3. My Alibinar Super Auto 135 is a 55mm filter thread. The Albinar 28/2.8 is supposed to be a 52mm thread. The 35/2.8 and 50/2.0 are 49mm threads.
