Tokina 80-300 SX-Z 4.5-5.6

Hi all!

Brand new here and very glad to see some very helpful and informative info on Pentax/Ricoh gear.

I'm awaiting delivery of a Tokina 80-300 SX-Z f1:4.5-5.6 lens (52 mm filter; read some very good reviews here before purchasing). I'll be using it with my trusty K20D. This will be my first non-DA lens.

The lens appears to have either a Ricoh brass pin or nub on the mount. I've read a bit about the possibility of that pin/nub becoming lodged in the AF slot of some cameras. That would not be good, so prior to mounting the lens on the K20D, should I remove it? I ask because in all the reviews here, I didn't see any mention of the pin issue.

Are you sure it's an 80-300? There is a SZ-X 60-300 with slightly different f-range, so I'm guessing you're getting the excellent little 80-200 SZ-X. (My review is here.) Yes, mine his the Ricoh pin, but it's the rounded nub type. I have not removed it, and I have not had problems. If you're concerned, you could remove it fairly easily.

Thanks mgvh. You are correct, it's the 80-200 SZ-X. I'll leave the pin as is and read up now on catch in focus with the K20D.
