Made by Samyang. Other than that?

Great Vivitar 28mm Bestiary: Details

It will be fully compatible with the K5 IIs. Just manual focus only...It will have a 'Ricoh' pin, probably a wide nub and not the dangerous kind.

Yes, you can use it with your K-5sii. Enable use of aperture ring in the settings menu. Enter the focal length when you turn on the camera. Put the lens in "A" and away you go. Metering and exposure modes should be the same as a DA, D-FA lens - only you have to manually focus and the focus point is locked on the center.

I have one of these lenses that I picked up on eBay a few weeks ago for $17 ($10 + $7 shipping). Mine's made by Cosina, as indicated by the serial number (96111040) and it has a 49mm filter diameter instead of 52mm. It's an interesting lens with a surprisingly nice bokeh. I didn't like it at first but It's started to grow on me. The Ricoh pin on mine is pretty tiny and doesn't pose a problem. No pinectomy surgery necessary, although I do make a point of moving the focus switch on the camera to the manual position before I mount the lens. I've used it on my K10D, Samsung GX-20 (K20D clone) and my K30 with no problems. I've also got a Pentax 50mm f/2 manual focus lens with the KA mount. Both lenses tend to lend themselves to more creative applications. Enjoy the lens and post some shots.

Does the ad show the mount end of the lens? One or two ebay sellers occasionally list K/AR lenses as Pentax KA mount lenses, when they are Konica AR-mount, which is not compatible with Pentax though it looks slightly similar. That mount fits the Konica AutoReflex camera line. The letters can get confused with PKA/R where the R stands for the Ricoh variation of the Pentax KA mount.
