Old K mount lens won't fit on my k-r body

I picked up a #00 Phillips at Menard's for $3 and was able to remove the mounting to grind off the offending flange. The dremel job (and the photo, sorry guys) aren't that pretty, but the lens works great now. :D Thanks for your help, everyone!

Thanks for the quick replies, everyone! I don't have the proper screw drivers to get the part off just yet, but at least now I know what I need to do and what I need to do it. :) I'll let you know how it goes!

Old K mount lens won't fit on my k-r body

I just recently purchased an Access P-MC 35-70mm f/2.5-3.5 lens to use with my Pentax k-r, and mistakenly thought that I could use the two together because the seller advertised it as a K mount lens. :( I just opened the package today and tried to fit the lens on the camera body, but with no luck. After several careful tries, it seems like the problem is that part of the lens mount is hitting prematurely with the inside of the body of my camera - if you look at the image below, the part that is interfering is the raised black ring that goes about 1/3 of the way around the inner black face of the lens. (It is the highest part of the lens when it is set face-down as in the photo, shown on the left half of the photo.) The length of this raised part seems very long compared to the rest of the lenses I own, as the comparable part on my kit lens only goes around ~1/8th the circumference of the lens, not 1/3rd.



After poking around the forums a bit, as well as some other off-site articles, I haven't found info on whether or not I need an adapter for this or if I can somehow modify the lens to fit on my k-r body. I did see some warnings about lenses with a Ricoh pin potentially being too long and needing to be removed before they can be used on Pentax DSLRs, but the lens I have has no pins visible whatsoever.

Sorry if my description of the problem seem simplistic - I'm new to this and haven't really developed a photography vocabulary yet. Any thoughts on how I can get this lens to fit on my camera? The simplest thing to do would seem to cut off the part that's sticking up too far, but I'm wondering if it can be solved in a more elegant way.

Edit: It looks like this person may have had a similar problem, but it seems as though the OP never returned to clarify the problem. Any advice on how to protect the glass parts if I have to take a dremel tool to this lens?...
