Use Canon FD/FL lenses on your Pentax.

Got any old Canon FD/FL lenses laying around going unused? Something I've never seen before. I just found these on ebay if anyone is interested.

Use Canon FD/FL lenses on your Pentax SLR camera

Product Features

  • Allow Canon FD manual focus lenses to be mounted on Pentax film and digital SLR cameras

  • Focus to infinity

  • FD lens lock, Multi Coated Optical Glass correction lens

Just do a search for "FD PK" at ebay.

Cheers.

Re: Use Canon FD/FL lenses on your Pentax.

Thanks Ron! Would be nice to be able to use my Canon FD 85mm F1.2 S.S.C. Aspherical again, but I'm not to keen on glass adapters...

So, what are you using that Canon FD 85mm F1.2 for now, a paperweight?

EDIT: The registration distance of FD is 42mm and PK is 45.46 so if the glass in the adapter is removed it would be like putting on 3.56mm extension tube. Hmmmm....I wonder how far that FD 85mm would focus then. I wish I had an old FD lens to try out myself. It would be an interesting experiment.

Cheers.

It's hard to argue about that... Of course you are completely right!

Actually with the 85mm it would still be good at portrait distances (headshots). I have tried this by holding the lens to the bayonet of my Pentax. Maybe I shouild buy two adapters and remove the glass from one of them.

Or just buy one and try it with the glass to see how it works. Then remove the glass to try without. You can always buy a second one later if it looks like the one with glass will work OK. That's what I would do.

EDIT: Did you see where I have been testing a Nikon-PK adapter (has glass correction) using a Nikon 400mm f2.8 on my Pentax DSLR?

Yes, Ron, I saw that topic (of course!). But I'm not a fan of adding glass to already good glass. You will not even see me mounting a filter on any of my lenses. I want uncompromised IQ which I feel cannot be achieved by using teleconverters or filters.

But I will buy one such adapter and show my findings here. Thanks again for bringing the adapter to my attention!

Ron I have a 20mm Cosina in FD mount and a 50mm f1.8 I could bring tomorrow? Interested?

Re: Use Canon FD/FL lenses on your Pentax.

Hi Ron!

EDIT: The registration distance of FD is 42mm and PK is 45.46 so if the glass in the adapter is removed it would be like putting on 3.56mm extension tube.

That would only be the case if the adapter sat flush on the PK surface. By looking at the auction pics, I'd guesstimate the additional distance at around 5mm, together with the 3.5 you mentioned, that's a rather hefty 8.5mm.

I've bought a cheap FD lens to see whether I could swap the mounts, but it's harder than feared, even after having read other descriptions...

FD's time will come again when there is a full-frame EViL...

...until then I guess APS-C and µ4/3 EViLs are the other solutions for those who do not want adapters with lenses.

Cheers
Jens

You're right Jens. This old brain is just not thinking like it used to.

Since I don't have, need, or want any FD lenses i think it is time to put this idea to rest......for me at least. However, I will keep my eye out to see if anyone in the forum gives these things a try. It would be interesting to see the results just for the sake of curiosity.

Cheers.

Re: Use Canon FD/FL lenses on your Pentax.

I bought one of those "scoptic" brands to try. I wanted it for my Vivitar S1 90-180 flat field and Canon 400/4.5.

Here is a test from the 90-180:
90mm wide open:

180mm wide open:

180mm f8:

If anybody wants, I'll upload the test shots from the 400/4.5.

Those shots from the Vivitar 90-180mm look pretty good to me.

I would like to see some shots from the Canon 400mm f4.5

Cheers.

Re: Use Canon FD/FL lenses on your Pentax.

I cannot understand why folks make a difficulties for them self and then try to find way how to resolve problem.

If someone has nice Canon lens(s) why he/she try to attach Canon to Pentax with some degree of degradation and limitations.
Just buy used Canon for $200-300 and be happy. Or this is kind of sport?

Why climb Mount Everest? or for that matter why bother trying to achieve anything? Or improve ones self and ones options?

Thanks Ron

I do think it would be too much of a compromise for the FD lenses I have looked at over the last few years......have been looking at a few as I had a feeling they would be useful again and cheap....maybe i will get one just in case.

FD (good) lenses USED to be cheap.....I fear I have missed the boat (just as with some nice Pentax lenses and the Nikon manual focus 200 f2).

Lenses from FD that I would not mind but are out of my reach and just the sort of lens you would not want to use with a glass adapter but if ever cheap enough (or I was rich enough) would get just on spec to play with

The concave 35 f2 (this one could be in reach)

50 1.2 aspherical L (one of these will come my way at some point....should have got one a year or two ago when I didnt want to pay maybe $100 more...now it is several hundred more mostly)

55mm 1.2 aspherical (the prices of these are nuts)

85 1.2 L (like the 50 1.2 these were in reach only two years ago).

24 1.4 aspherical L ( I am dreamin')

200 1.8 L I actually came within days of getting a UGLY one on KEH (I think it was two years ago for still over $1000, it is the same lens as the 200 1.8 EF mount with just the mount changed and that is supposed to be the sharpest lens pretty much ever....that is too much money now plus the prices have gone up a lot with good fd lenses.

300 2.8 fluorite (Surely Ron you have one already?)

There are a couple of zooms that may well be in reach...a short range 24-35 L zoom and a cheapish L 100-300 5.6 zoom.

I keep buying other things instead of things like these that really are investments.

Re: Use Canon FD/FL lenses on your Pentax.

I have a few FD lenses stashed away somewhere. Canon 50mm 1.8 and I think a 200mm non-Canon but still FD. They came with Canon AE1-Program kit that I bought, aahh, in 1983.

It turns out that I could use the filters that I had with it - 52mm, fit the WR lens.

Would be interested in finding if using as adapter would be worth it. I mean if the adapter is inexpensive enough

Cheerious!

Canon FD isn't Canon EF ("EOS" = Canon AF).

Some Canon FD glass is still among the very best - optically, many EF primes are virtually identical to their FD counterparts.

But there is no dSLR that natively supports FD lenses. Because of the FD's short register distance (and the peculiar bayonet), no current SLR mount can mount them without an optical adapter (EVIL cameras excluded). So FD lenses are a good bit cheaper than comparable lenses, although prices are going up due to new demand.
Being able to utilise them more fully is a rather understandable wish, I think.

Adapters are US $20 to $35 on ebay.
