That's fabulous, you really get to know your lenses, don't you John?

Could be a moderately interesting exercise when the weather's too lousy to partake of your favourite kind of photography. If only to satisfy curiosity.

[quote:3496ace15f="johnriley"]Generally a reasonable comment, but if you ever get the chance to use a CZJ 135/3.5 (the MC S version in particular) you'd very quickly change your mind. It could hold it's own against any similar lens made before or since. Bar none.

Don't even get me started on the Flektogon, Mir 1, etc

Interesting, but I've never owned both concurrently so couldn't say. Anyone got both?

Then presumably they'd be the New Assistant at a different shop by the weekend

Phew, just got mine in time then I got the Pentax-M version, but the A version is definitely more useful on a K digital.

The 1.7s are fetching well over their value on fleabay, IMHO. Either way, really happy with my f2, really sharp

Yep, I think Pentax needs to feature somewhere in the photo, either camera or lens. It is a Pentax User forum at the end of the day. That said, if a member also has a pocket camera (for example) of another make, it's not unreasonable that if they captured a really great shot that they wanted to share that they can post it up.

Just my tuppence worth

Did anyone say "kleptomania"

I think non-Pentax equipment is essential, as it acts as an excellent comparison. Most of my lenses are non-Pentax, and to be honest I'd not have it any other way. Wild horses and a crow bar wouldn't part me from the couple of bits of Zeiss glass I have, and similarly for the Russian Zeiss clones. I won't even mention my home-made accessories I think that while most people (especially on here) will sing the praises of Pentax quality, they understand that Petax aren't only manufacturer of high quality cameras and optics that ever graced our hobby. Some lenses from other manufacturers will suit a particular photographic aim better than a Pentax optic, and vice versa.

In summary, I'm all in favour of a healthy mix

You should probably get it done then. Pristine ones are fetching stupid money on Fleabay. Prepare yourself for it being a hundred quid or more though, but what price an old friend?
