Sears 28mm f 2.8 made in Japan, any good ?

Bought this from a friend last night for $15.00 . anyone know the maker and what year it may be ? I took a few close up shots this morning with my K50 , I'm no pro but they look pretty good to me.

The two sample shots makes me think it's a decent buy, especially at $15. Don't know anything about that specific lens, sorry. Shoot around and find out?

It works, and you seem pleased with the results. You got a good deal. Enjoy!

More to the point, though, this may have been made by Cosina. Reference this web page: Sears Auto f2.8 28mm M42 - Matt's Classic Cameras

Regardless, if you are happy with it, it is good. Especially for $15 !

The build and the name are clues. "Auto" in the name was common before the mid-1970s. From the late 1960s through to that time, Sears rebranded Ricoh and Mamiya/Sekor product for their M42 offerings, so it is likely that your lens has a "twin" with one of those two brandings. Mamiya had their own lens works and Rikenons of the era are thought to have been made by Tomioka. Whatever the case, your lens appears to be a winner at a very good price. Congratuations!

Found its Rikenon "twin"...

Looks good so far!

If you take a few more shots of stuff like brick walls, buildings, backlit subjects, the night sky, out-of-focus distant lights, etc., then you'll get a great idea of what this lens can do.

You'll will soon be the expert on this lens.

Have fun!

I wonder if stopping down a bit with the 135mm would give better sharpness and contrast. Which camera did he buy? I assume a Sears branded unit as well?
