Schneider Kreuznach 62,5mm/f2

I got this lens attached on anamorphic cinelux 2x. 

Very sharp wide open from closest focus to infinity.

All shots with Sony NEX5

optic scheme

 The lens produce nice flare  against direct strong light

35 КП-1.8/75

The lens was designed for 35mm film projector, it covers FF.

Not so sharp, infact it has some kind of soft but details still appear. 

Perfect for women portrait I guess.

How to attach ROW Visionar 77/1,6 on Sony NEX?

Some people asked me how to use

All you need are;

1. the lens ...Visionar 77/1,6
2. 52mm metal hood
3. 52-42 helicoid
4. thin 42-nex adapter

Yashinon 3,2cm/1,7

The Yashica half17 was a nice little camera, and deliver good results (samples with Fuji superia200 HERE ). unfortunately it was fallen, blades and shutter mechanism went error. So I decided to dissamble the lens then put it in use with NEX.
Yashinon 3,2cm/1,7 is an old lens, as long as not against strong light, it can deliver nice color/contrast. But even in strong backlight situation detail can be captured well, despite of poor contrast.
Is it sharp? Yes..fom wide open.

YASHICA HALF17 & Fuji Superia 200

Yashica half17 is a half frame film camera with fixed 32/1,7 Yashinon lens 

blades sometimes doesn't close correctly, which affect for wasting some frames. specially on 1,7 and bulb mode.

Selenium/light meter isn't working well, so I set in my mind the speed about 1/45-1/60, then light meter with Android based Beecam light meter on my old Hisense smartphone.

Fuji film I used was expired in 2013, process by lab, and I shot the film again using Sony NEX (sensor is dirty, it affect the results, looks like scratches, I leave it that way :D) and Kiron 105/2,8 lens, simple edit with Irfanview

PO-108-1A 50/1,2

The lens was designed for Russian 16mm projector

lens only

Sharp at center, at same class with big brand which made 50ish/1,2.
yet, sharp at center only, like common 16mm lens projector.
Color and contrast is good. No wonder I can see clearly it's coating, small CA appear (you can see when zoom to 100%)
However there's bluish flare against strong light

Konica Konishiriku Hexanon 50/1,8

Konica Konishiriku  has Konica F mount, which is shorter flange register than Konica AR mount.
I dont have the adapter yet, so I use helicoid adapter _ ring+glue gun like this

The results almost identical with Petri 50/1,7 mc

konishiriku

Petri 50/1.7 MC

The lens comes in Pentak K mount, appearance looks like Cosina Lenses. maybe Cosina made (?)
I read somewhere that some Petri lenses were made by other maker.
The results also looks similar to Cosinon 50/1,7
Nice lens by the way. sharp at wide open and good at stoped down at edges.
show some purple fringing but acceptable.
