  1. I have the Takumar/Pentax 28mm f/3.5 in several flavors: Super-Takumar: Super-Multi-Coated Takumar: SMC Pentax-M: and I like them all. The Pentax-M 28mm f/2.8 is nice, too, but doesn't seem as sharp, especially at wide apertures:
  2. Why would anyone saw off the auto iris pin? That would make the lens fully auto at full-width aperture with no way to control the aperture manually. The best way to make an auto M42 lens manual is to put a short length of plastic tubing around the aperture pin inside the back of the lens. That holds the pin depressed so the lens aperture can be controlled manually. Please don't glue the pin down with superglue. That not only ruins it for vintage M42 camera shooters (like me), but the cyanoacrylate fumes put off by the glue can cloud the glass.
  3. Don't worry about the radioactivity in those low-cost lenses. It's not enough to affect you, even if you use the lenses every day for a lifetime. All the lenses you listed are safe and excellent--as is the Olympus M. Zuiko OM 50mm 1.8 and the Super-Takumar 50mm 1.4 (8-element version if you can't stand the thought of radiation). The Takumar 55/2 also comes in a 1.8 version. You can't go wrong with any of them. I'd recommend the Super- or Super-Multi-Coated Takumars over the Auto-Taks, though--better flare control (although I have an Auto-Tak 55/2.2 that I love if I shoot with a hood).

  5. Here's one with an unusual M42 lens, the A. Schacht Ulm Travegar R 100mm f/3.3, a Cooke triplet design.
  6. Forgot to say, most of my adapters are K&F, although I have one Kiwi for Nikon F and one generic for LTM. I'm very happy with the K&F adapters, but I haven't used the Kiwi enough to make a final judgment.
  7. Being a long-time Pentax shooter, I have quite a few Pentax K-mount and M42 lenses as well as several M42-to-K adapter rings. So when I got my a6000 I got only the K-to-E adapter, and I attach the M42 lenses to it using the adapter rings. That way only one lens adapter is needed for both K and M42 lenses. If you want to do that I recommend getting the genuine Pentax adapter rings. They're more expensive ($35-40), but they fit the K mount better and have less chance of getting hung up in the K adapter than the knockoff brands do.

  11. M42 adapters to Sony E-mount are commonly available. A popular one is https://fotodioxpro.com/collections/lens-mount-adapters/products/m42-snye.
