I got this lens in a package of used Ricoh xr-p body.
It is in Ricoh R/K mount that works in (P) programmed mode in Ricoh xr series of camera. It has the notorious Ricoh pin that can jam a digital Pentax bodies. Though the Ricoh pin is retractable, it does stick out too much and will jam onto the AF/MF connector on the Pentax bodies. It will work like a K mount lens on a non-AF Pentax film bodies.It is quite easy to remove the pin and the zoom lens will just work like a regular manual K mount lens. I use it in M mode
and do stop-down metering with the green button on K20D. In Pentax K-x body in M mode, (+/-) Av button acts like the green button with a easier access location.The lens looks almost identical to the Vivitar Series 1 70-210mm f/3.5 by Tokina, the version 2 in the first three versions recommended by Mark Roberts. The filter size 62mm, the lens barrel, and the weight looks like the same lens to me
I test it out with Pentax K-x and performance closely resembles what I like about the Tokina Series 1 zoom.
Impressions & Notes
- It is quite good in sharpness
- Constant f/3.5 throughout the zoom
- Contrast can be better if a hood is added
- Close up is about 1:4 but I have not confirmed
- No zoom creep, 1-touch zoom, 62mm filter size, zoom quite easy to handle, good for MF
- Lens is small and lightweight as compared to v1 and v3 of Vivitar Series 1 zooms made by Kiron and Komine
- Good control of CA/PF in short experience with the zoom
