I am looking for a reasonable priced Portrait lens in the 80-100 range .
I lean towards the 100mm Orestor. Is the Exakta one better than the M42 ?

No, they are same lenses.There is Pentacon 100mm f2.8 M42 which is think a bit better optically and lot more worst mechanically.

Both lenses share same optical design, they shall perform same. The older zebra Oreston has perfectly circular 14 blades aperture, whilst newer Pentacon version only six. Due to this the Orestor has smoother bokeh stopped-down.

I took a few very basic test shots a while ago with the Tamron 105/2.5, Fujinon 100/2.8, and Pentacon 100/2.8

My favourite is the Fujinon, I have the older non-EBC and recently got an EBC version too, but did not have time to use it yet.

100mm orestor is VERY sharp lens if you don't get a bad copy. If you prefer softer lenses for portraits, the 135mm orestor/pentacon would be the right choice.

How does it compare with the Rokkor 100 MC 3.5 ? (not the macro) or the Rolleinar 85mm?

Attila: I didn't know, that zebra auto version exists. The 14 blades aperture has this older version with aperture ring on the front.

I have the Orestor 100mm, it's very good, but I find myself using my Sankor made 105mm f/2.5 way more. Very Happy

It's sharp with lovely creamy bokeh, and very easy to operate.

Here is my thread if you wanna have a look.

It usually sells for +/- 50$ and comes under different names like Spiratone, Seriese, Lennon, Aetna etc. Wink

Hi,

What about an SMC Takumar 105/2.8, that can be found cheaper than the Meyer Orestor ?
