Soligor 105/2.8 M42

[hoanpham]

Is there anyone own this lens? How is it? Compare with other lenses?

I just got this lens, haven't shoot a single photo with it, but it is smaller than pentax M100/2.8 which i though was the smallest 100/2.8.
The lens has 8 blades, but i read some where and it said 10 blades. is there several version of the lens?

There are several versions of this lens. All appear to be good, although the early ones with Orange numbers vignettes quite a bit on full frame.

I used to have one of these but I can't remember how many blades it had, it was a black version serial No H43442.
I thought it was very good and only sold it because I never used it. Here are 100% crops from some test shots I made:

Looks ok from F4.

I did run a small simple test of the lens.
Wide open: a bit soft, but usable.
Between 1/3 stop down or 1/2 stop down, it seems to be sharp.
At f4 and smaller, it is just razor sharp.
So basically, I use it between f4 and f3.2 (1/3 stop down).

I like mine:


Which has an H serial number. I think the above was shot at F4
