Accura Diamatic 70-230mm f22-4.5 M42 mount???

MD Optofonik · 06-19-2014, 05:08 PM

Anyone seen one of these? It's a monster. Got it with a lot of three "as is" for $23.00. I thought I was bidding on something else but that's another story.

The other two lenses are a also m42 mounts; a Vivitar Auto (#28xxxxxx) 135mm f 2.8 Auto Telephoto that has a slippery rubber focus grip (a light squeeze and it turns) , and a Mamiya / Sekor SX 135mm f2.8 (It's pretty much junk. The focus ring feels like it's teeth have been worn down to nothing; gotta squeeze it hard for it to actually move the elements).

I already have a Takumar (Bayonet) 135mm f2.5 but I thought I might put my Pentax m42 adapter on the Vivitar and take it out for a spin with my MX since it's actually rated slightly higher than the Takumar. Will it focus to infinity with the Pentax adapter? Don't know about taking the Accura out though; it's a bludgeon.

Looks very similar to my Soligor 90-230 f/4.5. Same cosmetics, same size. Probably came from the same factory. I wish I could tell you what it's like quality wise, but I haven't mounted it on a camera in decades. I might turn it into a fish tank. Or a baseball bat.

Too heavy for a baseball bat.

No, really, it's heavier than the average baseball bat.
