Can anyone advise as to the quality of these two lenses please
similar to the Yashicas and could well be made by Tomioka.
Helios lenses do vary, but about 1 in 4 is usually very
good.

The Rikenon is rare in M42. It should be sharp, probably
similar to the Yashicas and could well be made by Tomioka.

does 'rare' equate to worth a lot? Please let it be true!!!

Probably not, unfortunately. It should be a nice lens, though. I've got a Chinon 55/1.4 that is also Tomioka-made and it's pretty good. The bokeh I get with it is different to the Pentax and Helios.
Definitely worth getting an M42 adapter to have a play, anyway.

Is £10 to £30 a lot



The Chinon 55mm f/1.4 is an awesome lens usually
goes for around £65 which is cheap for the super
bokeh that it has. I have the f/1.4 and f/1.2 versions.

i was sort of hoping that the Rikenon was worth somewhere in the region of £3, million. Y'know, a bit like that photo of the River Rhine that sold recently.
That said, I'm always happy to accept an offer in the millions for this lens. I'm sure its a work of art. I'll even go and get an adapter and lens covers and throw them in for free.
Just order an adapter, so i can have a play and do some comparisons. with my Pentax A and M 50mm f1.7s.

lenses have good bokeh wide open as well.
I doubt if you will notice much difference in sharpness.
The Pentax lenses should just edge it.
This is a good site for bokeh samples link
