Scrounging around down in the basement, I came across something that made my day.
Lamenting selling off all my old glass before discovering the joys of video, including a mint Zenit with Helios 58mm f2, I consoled myself with a new found usefulness for my 1960’s 25mm half frame Pen lens.
In an old box of bits, not sure where or when I got it, I found among other things a nice condition Praktica camera with a screw mount Helios 58 f2. It is very old, like first series, but the aperture works, both with the clicky ring and the handy step-less one and it looks quite clear of haze.
$8.00 adapter ordered and away I go. Of course it is quite a long lens on M43 (120mm), but I have the shorter 25 and the character filled Oly 17 for wider again.
Bit of fun.
