Using M42 lenses on PL cameras | Comparability List


Once in a while I get asked about vintage lenses adaptable to PL mount cameras like Red Epic or Blackmagic URSA Mini (which can be bought with a native PL mount).

Unfortunately the options are limited to Arri Standard/Bayonet and LOMO OCT18 mount lenses with not much else to choose from, at least not without a professional conversion.

If we look at the cheap vintage photo lenses, then there is even less to choose from.

RAFcamera makes the M42 to PL mount/adapter which looks more or less like the ARRI B/S to PL ones, so in theory M42 lenses can be used with it, but unfortunately the options are limited to the lenses with the rear part no wider than 51mm, in particular the last the 8.54mm of it (see below).

June 2016 update: RAF camera has released an improved version of the adapter with the 53mm opening allowing, adding 2mm that can make a massive difference to some lenses that previously were close to being compatible, but didn’t quite screw all the way in. After testing the lenses that were close to being compatible with the old adapter again, this time using the new one, I’m glad to say I was able to add 2 more lenses to the comparability list below.

What’s more, the improved version of the adapter now has a set screw in the m42 flange. It allows one to secure the lens inside the PL mount, ensuring no there is accidental unscrewing of the whole lens, which is common with M42 mount lenses, especially those with tighter focus rings.

I’ve been testing this adapter will all my M42 lenses (compatibility list at the bottom). I should say right away, that there aren’t many M42 lenses compatible with this adapter, because most lenses are wider than 53mm at the back (it’s very easy to tell when lenses will not be compatible). The lenses that have a chance are the ones that have a long mounting section like the Helios 44-2, have a cone shaped back as found on MIR-1 and Pentacon 135mm (15 blade version) lenses, unfortunately the size and positioning of the focusing ring on MIR-1 means that it’s falls short of being compatible compatible, but some sort of modification might be possible.

I was glad to find out that Helios 44-2 58mm F2.0 works with this adapter, because it’s not only my favorite lens, but also one of those lenses that even high end users are happy to to play with; however positioning of the focus ring on this lens makes focusing pretty difficult unless you add a follow focus gear, like I did below.

Alternatively you can get one of these rehoused babies, but it will cost you much more that building one 🙂

Another lens that worked with this adapter is the Industar 50-2 50mm F3.5 (below), which is a tiny, fun lens (my review) and I must say I love how it looks inside a PL mount! Smallest PL mount lens anyone? 😀 You can use it as camera port cap with an added benefit of lens functionality 😉

And finally we come to the Comparability List.

  1. I bought two M42 lens and come very researching about it, like the content, but it’s a shame I did not use PL mount, currently use Nikon F and also find little information about it.
    The M42 lenses seem to have full compatibility with the sensor and the majority operate at greater focal length than 2 meters.

    sorry my english do not have much experience in grammar.
