Anybody got experience of this old manual lense (performance / weight etc)? Also would it go auto attached to a x1.7.

I've got one and tried it with the AFA .... very so-so. I think i've ditched the test shots, if I haven't I'll post a few but I've just had a clean out so can't guarantee they are still around.

It's very heavy lense - all metal construction of course. OK by itself but nothing to write home about. If I remember correctly even the 55-300 out-performs it.

I had one once. Image quality was OK, but it was a beast of a lens - heavy and with very stiff focusing.

Although the 400mm 1:5.6 is larger, and of a roughly similar vintage, I find I much prefer it.

If you are after a manual 300mm lens this one might interest you.

It looks a bit tatty, but the optics are clean. Both the M and A versions of this lens are held in very high regard within Pentax circles.

Yes - the M* and A* lenses are excellent and surprisingly compact. Both are prone to some purple fringing (but can be processed out) and the only other downside (apart from MF) is that they do not focus terribly close. Other than that, highly regarded and often priced to reflect that!

With a 1.7x converter would you get any autofocus?

I think you probably would, but I have never used that converter so others need to advise.

The A* works fine with the 1.7x and should AF although I've never tried it I always use MF.

You can focus a lot closer with a small 6-12mm extension tube.

Never any any PF problems on a K20D.

Algi - sorry to be picky but the one I have in mind is a M* - so does the same apply?

They look the same to me so it would apply. The only difference seems to be the A setting which you lose on the A* when using an extension tube anyway.

The 4m focus isn't usually a problem, you'd be lucky to get that close to a bird anyway.

This shot was taken with the lens in question (K300/f4)

The M* 300 works just fine with the x1.7 converter.
I remembered this thread where one of the forum users put his up for sale.

there are some example shots of the M* 300 & x1.7 converter.
