Tokina sz-x 60-300mm mounting problem

Hi,
I'm a total noob who recently picked up a used Tokina sz-x 60-300mm f/4-5.6 lens in the clearance section ($50) at a local camera store but find that it won't mount on my K100D, but will on a Super Program. The thin blade on bottom of lens sorry, don't know the technical term) is too long side to side and wont clear the tab by the autofocus motor contacts. Would it be worth trying to modify this by cutting off and smoothing a chunk of the blade or should I just return it? Seems like a nice zoom range and I assume the quality is decent. Thanks for your advice.
Eric

Hi Eric - welcome to the forum.

There's been a few different posts about the "guard" preventing the lens from mounting - simply remove the "piece" from the lens, cut the offending part down to size (compare with another lens), hit it with some flat-black paint and re-mount on your lens. Ta-Da - works like a charm!! (Just make sure you remove the part from the lens before you cut on it so you don't get metal shavings in the lens. )

Thanks for advice

Thanks for the tip Chip, especially about removing the part first, I'll attempt that this weekend. Beats my idea of putting the lens in a vice and going to it with my hacksaw.

Can you take a picture of that guard? I'm curious to see how it compares to the lenses I have, including my recently acquired Tokina SZ-X 28-200.

Quick Photo

Here's a quick photo comparing the Tokina to Pentax-F 135mm F2.8, sorry about the poor quality.

That "guard" looks very different from mine.

The guard on the Tokina 28-200 I have looks similar to the guards on 4 of my other lenses, both manual and auto, and is similar to the one on the Pentax F 135.

I'm not sure how much cutting and dremeling you would be willing to do, but before you go there, you need to figure out what's sticking.

Mounted up

The surgery was successful and I ran a few test shots, it seems pretty sharp and constrasty stepped down but has some major PF going on, looks like I better save for the 55-300!
