Re-bonjour,

Here are two f1.4 "Franken-lens" modifications of mine ... I have been looking for a Canon FD 1.4 because I have a de-glassed FD/PK adapter to use as an extension tube, but also want to modify ... ... yes, I am a very sick person on many medications J

Thank you both for nice comments.
The lens is great for sure. Much better then my photography "skills".

The conversion is sort of complex but it turns the lens into a K or M lens so that you can use the green button for stop down messure.
Very nice being able to focus at 1,4 and the camera then stops down just as any old Pentax lens. It is also reaching infinity and even slightly beyond if needed.

I am working on a modification kit that Im planning on selling.
It is fully reversable and non destructive. Right now Im working with a machineshop and we are programming the cad apps he uses so that we can produce the different parts. I will start making this 50/1,4 lens and when I get that working I will make more kits for other Canon FD lenses. I have a lot of them already converted.
The only lens in my camerabag that isnt a FD lens is my Sigma 20/1,8 but yesterday I tried an FD 20mmF2.8 lens on my K5 and wow. That one is supersharp with nice rendering. Will convert that one too asap but Im short on time and the 50/1,4 is priority 1.
Btw. Still dreaming of a FF Pentax so that I can use these old FD lenses the way they were ment to be used.

When I have my first FDn 50/1,4 kit ready I will start a thread to explain what I have done and what I will do if I can sell a few.
I was thinking about, perhaps selling a few copies at a discount to a few selected to get some real life testing and hopefully constructive reviews as well.

Anyways. Sorry for not telling more about the conversion itself but Im hoping to make a small income on this some day.
That is if it all works out the way I hope.

Will do.
It still needs work and at the moment Im in a different part of the country from were the machineshop is so progress is a bit on hold. Going back late november. Not sure if I have a product by then. I have to adapt after my machineguys schedule. We still need to sit together and program the rest of the parts and then actually make and test to fix any obvious problems. After that I will go into next phase. Ill bump you then.

Thanks ... here's my de-glassed FD/PK adapter with a FD 50/1.8 on it ... and a very low light (bedside table lamp) wide open SOOC shot that I just made, because I could not find the other previous test shots ... I want to try this adapter with the f1.4 (that I hopefully will receive some day) and would like to convert a 1.4 to a straight PK as well ... thanks again, J

I used to use Canon FD for all my photos till I went Pentax digital. I sold quite a few of that lens collection but still have a nice array to go with my T-90 body. I think one of those is the 50 f1.4 which I bought for low light and was always pleased with its results. I also have the standard kit 50 f1.8 and some other short primes. I think it is about time for me to part with all that gear. I know it is not worth very much so much of it I could just give away for the cost of shipping or mailing.

I am interested in those too. Can you please let me know as well. I was looking to convert my FDn 50mm 1.4 to P-K for long time. Thanks!

Will do!

As an update.
I have created the screws needed for the conversion. It took some time but finally the biggest obsticle is conquered.
In late Jan and Feb I will hopefully get the last pieces ready for show and test.
It is very exciting and great fun to be able to take this project further and further.

More news soon.
