You can still visit you know - we will still talk to you!

Yes, I know that. I was broadening the response, just out of interest.

Anyway, there hasn't really been any shortage of lenses in the Pentax range over the years except for a patch where the old manufacture was starting to give way to the new. There seems to be a perception that there weren't many lenses.

As regards telephotos these might be rare anyway, as they were big, heavy and expensive lenses. This might well apply to all marques, although there will be a supply of very battered ex-professional-use Nikon lenses around.

The OP did actually mention alternative MF lenses, so I'm sure we can open the discussion a little. It's never stopped us anywhere else...

I'm pretty sure it would hurt, but I'd try!

The MX is a well designed and reliable camera, but some of them are now getting quite old. It might be a good idea to get any MX overhauled, especially as the shutter mechanism will slow down and start to "taper" -that is, the speed of travel varies over the run of the shutter, causing uneven exposure.

A mint MX fully working is a beautiful thing. I'd love to buy a boxed unused one, and there probably is one somewhere.

Indeed it is, but I don't see the point you are making?

You've missed out that I mentioned the 500mm. There are also many longer primes as well as zooms, but the two unique zooms are interesting.

Don't forget the manual focus ones that also iclude the 500mm, the 400-600mm zoom, the 250-600mm zoom....and so on. Lots of long lenses, some quite unique.

There are not many zoom lenses that are actually the same as the nominal value in the name. A 60-250mm could easily be a 63-240mm.

Don't forget that many lenses also change focal length as they are refocused, so try the lens at different distances to see if it varies. Close up focal lengths may well be shorter.

Please keep to the point - this thread is about some specific lenses for sale.
