Rollei lens for MF projector

[luis_marco_de_sebastian]

Hi

I have just bought a rolleivision 66 (not AV version) with a AV

Xenotar 90mm 3.5 HFT lens and while it delivers good results i have

to set my screen too close to the projector which sometimes is a

problem.

So i am looking for a 150mm lens (the 120mm apogon is out of my

price range) and i have taken a look at these 3:

 

Heidosmat 2,8 / 150

S - Heidosmat 3,5 / 150 MC

Xenotar HFT 2,8 / 150

 

I already know about the Xenotar and i think that it is the best of

the 3 but would like to hear what do you think about these two

Heidosmat lenses.

 

What surprises me is that the S-Heidosmat is supposes to have better

resolution than the non S version according to the rolleiclub:

http://www.rolleiclub.com/rollei/projectors/index.htm

but they do not list the S-heidosmat 3,5 but the S-heidosmat 2,8

Can you guys help me with this? I do not think it is the cheap and

plastic made 150 3,5 that came with the p66 projector but i do not

know for sure.

 

thanks in advance.

It seems that the S - Heidosmat 3,5 / 150 MC is offered as a cheap alternative to the costly 120mm apogon for the 66 duap P. At least that is the way it lookks in the B&H site. (it will fit my rolleivision 66 too)

But what about the opptical quality of this lens compared with the 2,8 Heidosmat and the AV Xenotar?

Both Heidomats 150 2.8 I have are definitely better than the plastic 150 3,5 I have used.

<p>

The 3.5 showed quite severe colour fringing and of course they are darker as well.

Don't know though if there are S and non-S 3.5 heidosmats.

Hope this helps as a first piece of your puzzle.

I am in the market for the 90mm. I have a 3.5 150. I want to upgrade. If you are interested in selling the 90mm email me. edward12@on.aibn.com I am in Toronto Ontario Canada. I am not tring to fob the 150 off on you I am content to keep it for occasional use in larger rooms. I want the larger image of the 90 for my living room.
