yes and no - you don't need an adapter for it, but that long aperture-lever-guard will have to be altered/removed for it to mount on your camera....

Quote:

Third Party Variants of the K-mount
Pentax made the original "K" mount available for other camera manufacturers to adopt. The goal was to create a universal standard bayonet mount much like the M42 screw mount had been. Ricoh, Chinon, and others produced cameras and lenses with the "K" mount. Unfortunately, with the introduction of the "KA" mount, Pentax reversed the decision with the result that the other manufacturers either abandoned the "K" mount or developed their own, somewhat incompatible, enhancements. Several third party lens manufacturers produce or has produced lenses with a K-mount. There are no issues with current third party lenses in K-mount, but for older lenses there are two traps to watch out for:

The infamous "Ricoh pin". . . .

The other trap is the shield that protects the aperture stop down lever. The image to the left shows what the shield should look like and does look like on a genuine Pentax lens. Some older third party lenses have a much larger shield which prevents mounting the lens on a Pentax DSLR. Current third party lenses (Sigma, Tamron, Rokinon, etc.) have correctly shaped shields (or no shields) and pose no problem . . .

Yes, the long aperture lever guard is the problem there. Don't try to force it on the camera, you'll break it. Remove the whole piece of metal and either leave it off (though that means dust can more easily get in, plus the aperture lever will have no protection) or cut the lever guard down and put it back on the lens.

I've cut down two of these on Vivitar lenses, it's not that hard.

I am pretty sure you meant trim the guard? It may not be clear to some that it is the extent of the guard and not the height of it or the length of lever that causes the problem.

Just for clarity, what do you mean by "old model"? Mark Roberts indicates zero compatibility issues for the first five versions of the six Series 1 70-210mm lenses. If there is an issue with the sixth, it was not noted in fwcetus' review of that lens on this site. I only own the quite compatible v2 (Tokina) and don't recall any reports of mounting issues with the other versions.

FWIW, the lens in the thread you referenced is not a Series 1 lens. It is the Viv 70-210/4.5.

I know it is not a Series 1 70-210 at the images i posted, but a good and visual example of the problem with a large guard.

I don't know the version number of the Series 1 70-210 who had the large guard, but i am absolutely certain there are versions of this lens with a larger guard. My brother owned one with the larger guard that wouldn't fit his Pentax camera without modifying, (i think he owned a K200 at that time)

It took some effort, but I did find a two reports for the v1 (Kiron), made from 1975 to 1981.

Other reviews for that version on KAF2 bodies have not mentioned a problem, so perhaps it is not that way on every copy of that version.

I came up hands empty for multiple other search strategies using Google.

Yes, thanks, I've amended that now.

I had some photos online to show before and after but those b*stards at photobucket are holding me to ransom to even see them

Never rely on some outsider to store your photos, do it yourself, and keep backup copies. With the price of USB storage so cheap, more than one backup is easy.
