Conversion to PK of LensBaby optics

cyberjunkie · 06-04-2018, 09:03 AM

Recently I found a few interesting LensBaby optics on eBay.
Unfortunately it seems that those in Pentax mount are not so common.
Did they ever made any LensBaby objective with interchangeable mount?
Is it easy to convert those in Nikon mount?
I have no idea how they are made. From the pictures it's unclear.
If they made the lenses in T-mount it would have been so simple...

Any information is welcome

cheers

Old lens babies were for one mount only. AFAIK, the new series has interchangeable optics within a "composer" unit, so that you can swap mounts pretty easily as long as you have multiple composers.

A possible way to handle a Nikon one would be to replace the nikon mount with a flanged m42 and an m42 to k adapter. It might just work. It has for some in the past.

Won't a F-mount LensBaby just mount upside down on a K-mount camera? They don't have any electrical contacts...

Yes that too should work. I have mounted pre-ai 50mm lenses on my K mount - but it isn't as secure as replacing the mount. With the lens baby that's probably not a big deal.

the Composer Pro II comes in K Mount - can't the optics be swapped out in those?

Yes, I have a Composer Pro with a Sweet 35 Optic, that is a Nikon mount and use a Fotodiox Nikon to Pentax adapter. It works just fine.
