Vintage SMC Pentax-M 135mm F3.5 Lens on NX1

SMC Pentax-M 135mm F3.5

I started looking into Pentax lenses after purchasing an early 1980's Pentax K1000 SLR film camera. I picked up this 135mm lens on ebay for less than $50.  The K-Mount has been the standard for Pentax for over 3-decades. Besides for use on the K1000 film camera, I knew I could easily locate an adapter for my Samsung NX1.
This lens was manufactured in Japan either from the late 70's or early 80's.

This link leads to the Pentax Forum where specs on the lens and a member discussion and photos can be found.

For a definitive information website on Pentax lenses, see link here:

Looks nice on the Samsung NX1...

The photos below were street photography taken beginning about 1-hour before sunset, downtown Phoenix, Arizona.  All photos are shown as they came out of the camera.  All shots were handheld (difficult to steady at 135mm or 202.5mm - 35mm Equivalent for APS-C Sensors)

COMMENTS ON THE LENS: I'm really happy with these initial photos using the SMC Pentax-M 135mm F3.5.  The photos appear sufficiently sharp and nicely textured with natural color. Sweet!

    1. Thanks Jorge for your interest - If there is some additional info you would like to obtain, just let me know. I'm going to post in the next few days some 'test' photos from a vintage "Kalimar" 50mm f1.7 lens I picked-up at a pawn shop for $15. I was impressed with the Kalimar lens - The photos were gorgeous!
