Nonur, See this link for photo of Varimagni on Pentax. Graham.

Oh heck! I got it at a fair price, £40 British Pounds, in mint condition with its case in 2010 It is the "M" version designed for the M series Pentax film cameras, but works really well on my Pentax K-5 and the K20D Search "Angle finder pentax" on English language ebay sites. (NOTER that the Olympus OM varifinder angle viewer also works perfectly on Pentax digital.)

I got my finder from Ebay. Very useful for tripod work too.

Shows the strengths of those Helios lenses, cut my teeth on one of those in the 1970s.

I would have this on my wall.

Real people!

I like it, and I like the 'different stories' that I can imagine in the image.
