Found this lens on ebay for real cheap. Asanuma brand, identical mechanically and presumably optically with the Mamiya/Sekor 2.8/28. The only differences I can see are very slight cosmetic ones like the colors use on the focus scale and the pattern of the focus grip.
Took a couple quick test shots to get an idea for what to expect from this lens, and it performs very well in my opinion.
Bokeh is sort of ugly wide open, but not the worst I've seen for a 28. Softens considerably when stopped down to f/5.6.
Crops: no sharpening or adjustments, hand held:
wide open
f/8
f/5.6
I'll have to get the tripod out to really see what it can do, and look forward to shooting it with some film. Not bad for a $9 lens, one of the better 28s I've had. Maybe even the best once I get to use it more. |

Is this an older lens ?
Metal focus grip, etc. ?
It may be a Tokina.
Many of the first generation Mamiya lenses are from this line, and Asanuma was a distributors brand that carried a lot of Tokina items.

I noticed that the lens looked similar to the Mamiya one, and when I got it I confirmed that it is indeed mechanically the same. I will get some pics of the lens. |

It looks a fair bit like the Tokina made Soligor and Vivitar, like the original T4 series.
Or perhaps not.
Of course the Tokina lenses are seen dressed up in all sorts of styles as they were sold under so many brands for many years.
Whats the filter diameter ? The Tokinas were 58mm.
A very similar lens that has fooled me before is from Sun.
Here is a post I did on the origins of this lens -

Yes, it has the 58mm filter ring. So Tokina it is I guess. |

Still impressed by a 28 that is this sharp wide open, although I've noticed that it tends to render colors very coolly, even here with the reds bumped up a bit in post, it's it's still biased towards cool colors. |

This is a good lens it seems.
