'best' non-Pentax MF K mount prime lenses

Fellow Pentaxians,

Just a conversation starter ... what is your 'best' non-Pentax manual focus K mount prime lens? I've put 'best' between quotes to indicate that it is a highly subjective ranking. I am curious to know your personal favorite. Let MTF charts and all other technical fluff for it is. What is your personal precious gem?

I'll kick off by stating that I really liked the Vivitar 28mm 2.0 close focus lens. I used to have one for Olympus OM mount. If I ever come across a reasonable priced K mount one, I'll grab it. Another one I really like it the Flektogon 35mm 2.4 lens. Mine is permanently converted to K mount. A fine conversion, but nevertheless stop down metering only. And that is a bit of a pain in the butt.

Finally, I do own a Revuenon 50mm 1.4 lens. Wow, that thing is sharp and contrasty! Never done any serious testing, but from it results I get it looks like this lens is way better than the Pentax-M 1.4 version and the Pentax-FA version.

Never tried a Vivitar Series I 90mm macro or the Tamron 52B or 52BB 90mm 2.5 macro lens, but I would love to try one out.

So there you have it. My 3 personal favorites and 1 (or 2) could-be favorites. What is, or what are, your favorite non-Pentax K mount prime lens?

Thank you very much for all the advice given.

A friend offered me his K10. With a new-to-me fully functional K10 in my hands I bit the bullet and tried the isopropyl alcohol trick. And guess what ... it worked! I now have two working K10's.

Thank you for your advice, and a very big thank you to RoseyD for the offer. Highly appreciated, hopefully the camera will find its way to another home.

No first hand experience with PMK Pyro and Fomapan 100, but according to various posts I've read that should work great. Rate as 50 ASA and develop 1 + 2 + 50 for 11 mins. Good luck!

LS lens on 645N

That should not be the case. If you haven't cocked the lens shutter and you're using the lens in leaf shutter mode (that is you've selected a shutter speed on the lens barrel) you should have a blocked / black viewfinder until you cock the lens shutter.

It is not completely clear to my whether or not the Sigma flash fires. Your claim that is works in focal plane mode gives me the impression that it does not fire in leaf shutter mode.

Have a look at the section 'Using in Leaf Shutter Mode' of the LS lens manual. Using the lens on an original Pentax 645 I can vouch that the procedure how to use the lens is exactly as described. I also used this lens on a P645N and I am not sure if the camera switches to 1/8s shutter automatically. Have to check that.

I would recommend to check out the manual and make sure you'll notice the view finder blockage when you've tripped the leaf shutter. If you do not see the blockage, your lens in malfunctioning hence no flash output.

On a side note. You should be able to test drive this setup without film. Unlike the 645 the 645N fires when no film is loaded.

Good luck!

From a non-rational point of view ... support Pentax, not the company that ditched them
