Pentax-m 20mm F1.4?

I stumbled across this website in Italian describing a hitherto unknown Pentax lens to me. It's not in the database either like some other unicorn lenses.

Google Translate

Anybody ever heard of it?

Looks more like a K than an M - but no matter, never heard of it.

I know. The writer calls it an M. But K seems more likely to me too. Pentax was really developing a lot of wide lenses at that time.

The picture is certainly of a K series lens.
There was a brief discussion in DPR in 2007 about 1976 prototype K20/1.4
Absolutely nothing concrete.

There was a similarly elusive M series 35/1.4 of course. I don't know anyone who has seen one of them in the wild either.

Is it too late to put it into production?

Bojidar Dimitrov (the original creator of the K-mount page) claimed to have handled the dedicated lens hood for the M 35 1.4 complete with packaging, and did believe a few copies had been sold. I am not so sure myself, otherwise some images would have appeared over the intervening 40 years surely?

I was thinking the same thing, but I bet there were reasons back then it didnít go anywhere...

But something like this would be a really cool Limited...

A "Limited" with a 77mm filter diameter? I don't think so

And it weighs half of a DFA*50, so thatís a good point

Oh, that old thing? Several years ago I picked up three of these lenses at a garage sale, BNIB, never used. The (original) owner said he picked them up on a business trip to Japan but never used them because he never shot wide angle. Just clearing out the junk.


I forgot I had them -- they've been stored in a dry box in my basement. I'll have to get one out and try it.









(JK. Looks like an interesting lens...)

Sometimes these prototype lenses do surface and here is an example:

Pentax K8.4/2.8 Fish-Eye
