Orestor 100/2,8 on Pentax KP

Hi everyone. Just today I received an Orestor 100 / 2.8, which I took deliberately for portraits and its bokeh. So of course I will use it at 90% at f / 2.8 ... but I noticed that it has a small button that, if I press it, closes the diaphragm to the chosen value, otherwise it remains always open. Well, I remember that on my helios 58 putting a piece of aluminum paper on the side of the contacts with the machine, he managed to close the diaphragm at the time of shooting. The same thing you think is possible also with the orestor?

Magnification in Live view

Hello everyone,

I'm trying with great satisfaction my new KP with an Helios 58mm f / 2 manual focus. I was wondering if there is a way, during focusing in live view, to zoom the image so as to see more clearly the focus peaking on the subject.
If I remember correctly on the K5 was possible through fn button (if I remember correctly).
Thanks

Yes, I've seen in third-parts lenses ... but I still have many doubts ... I really like the Russians, but I fear about chromatic aberrations. As sharpness I think they are on the same level. In the past I had a pentax (Bayonet) 3.5 and I remember suffering from a strong purple fringe ...

Thanks, but close-focusing for me isn't a problem, I prefere sharpness and best CA control

Hi guys,
I'm looking for a 135mm lens, very sharp and that does not suffer from chromatic aberration. Currently I already own a tamron AP 90 2.5 with PKA ring (the one with the diaphragm transmission, to be clear) but I do not know if the TAMRON BBAR MULTI C. 135 / 2.8 ADAPTALL 2 can be the solution to what I look for. My budget limit is around 100 euros (which is why I'm not looking for autofocus, otherwise AF would be the best). I heard good things about CZJ, Petri, Takumar etc ... but the Tamron fascinates me. Tips?

Hi to all
for months I used K3 (has a few months to live) and, at the same time, also my (as new) K5. I found K5 better for highlight exposure management, and high iso also.
I'm not enthusiastic about K3 and then I think to sell it for switch to K5IIs... or what other Pentax aps-c cuold be similar (or better?) to K5 as high iso management? I don't know all pentax aps-c...

Thanks a lot

Tamron 300/5,6 (54B): adaptall-2

Hi to all
recently bought a Tamron 300/5,6 (54B) after reading the very good reviews on this site.
I have adaptall-2 (simple) ring and adaptall-2 ring with electic contacts.
In you opinion is better to use adaptall-2 with electric contacts or is the same also with simple adaptall-2 ring?

As I can see lens group seems to be clear, no fungus, no haze... but on my K5, tamron 300 quality (with simple adaptall-2 ring) seem to be not great.

Thanks a lot

I think so... also! There is very significant exposure compensation with focusing screen different from K3 kit.. very very significant!

Hi to all,
recently I placed on my K3 an "Bresson" dual 45 split image focusing screen bought on ebay. Pressing green button to read correct exposure seems works fine, with M mode, from 1,2 to 2,8 on my manual lenses but in I use from 4 to 11 the images are really too too overexposed.
And then I placed again factory K3 screen and, whit the same test, it's all ok!
Is there a problem of my focusing screen or it's normal with any focusing screens? I'm thinking about to buy and Canon ee-s focusing screen but if the problem would then be the same I don't buy it.
Could anyone tell me his really experience and suggestions?
