Anyone know if it's a good lens? I just got it with some other Pentax stuff. It's pretty compact and feels very good. |

May be a tomioka lens. I saw a pair of tomioka chinon 2,8/100 in M42 mount.
Can be a very good lens.

Against all myths with Tomioka, Leica, Takumar.....its a good lens. [...]
I would say that the lens is made from the same manufacturer which built some lenses for Hanimex and Beroflex in the late 70s and early 80s because i had several lenses with very similar case design. [...]

And it's one of the best lenses sold by PORST btw....

Today I received my Pentor 100mm F2.8, which appears to be the very same lens as the Chinonflex and the Porst:
Any ideas about the maker? I don't think it's a Tomioka, as the Tomioka variant I have seen had a focusing helicoid that turned in the opposite direction.
It's a good lens; very sharp already wide open:

I've also seen this branded as Hanimex. Mine was sharp too but suffered lowish contrast. Had a nice blue coating!

Nope. Hoods are for wusses
I have Hanimex's older version of this lens...it's actually a 105/2.8 but with the same minimum focusing distance. This one is made by Tokina and has a serial begging with H.

Interestng! Don't laugh, but I made the product shots of the Pentor lens with a... Hanimar Tele-Lens 105mm F2.8. With a serial number beginning with... H! It's a T-mount lens by the way. But it's not the same lens; the differences are too big. The MFD is the same though.

Ahh. I'll let that idea go then  It will be interesting to see how your 100mm performs outdoors, please keep us posted

In the meantime here's an interesting photostream made with the Porst 100/2.8 (and I believe Praktinafan is a MFlenses member too):

I think PBFacts disputed this recently. Can't find the thread though!

I have one with Soligor badge. The focus ring turns into opposite direction and it has a build-in hood but still it seems to be the same lens. According to this forum common effort to identify the Soligor serial numbers it is Sun made lens. |

It's remarkable how sharp the Pentor is, wide open! No softness at all, but razor sharp in the plane of focus. No low contrast either. In the viewfinder, the subject just snaps into focus. I consider this a sleeper lens!

Wow very sharp! Never heard of Pentor though, at first I thought you made a spelling mistake for Pentax hehe
Time for me to hunt for one of those.

Awesome pics. I am curious about the petri. I have a few petri lenses and they shoot well. What is the story behind petri?
Also, these pics make me tempted to find a way to keep the Vivitar 100 mm f/2.8!!! Wish I could use it, but it is up for grabs. |
