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.

Playing with anamorphic lens

I have this lens attachment for projector lens for awhile,  Rathenower Rectimascope 48/2x. I dont have time to play with it. Because it has to be clamped on front of normal lens.

I have to stopped down at least f5,6-f8 to get sharp enough image.

I put it in Meyer Trioplan N 100/2,8 V handheld, because I dont have the right setup.

First sample the image strected horizontally, the 2nd one was vertically

anamorphic twisted wide, everything including the man looks fat LOL

anamorphic set, everything looks thinner

after edited to make it right

original with trioplan, without anamorphic

This one is with Minolta Rokkor 35-70/3,5 at 70mm, shorter than 70mm will add vignette

Pullin Pulkinar 75/1,6

very old projector lens, low contrast and vintage look results

Ernst Leitz GmbH Wetzlar Summicron 5cm/2 ltm

This lens has beautiful silver finish, quiet heavy for the size of RF lens. Too bad it has haze which affect to IQ (lack of contrast and ghosting/softness in some case)
MFD is 1 meter like common RF lens, so I put it in helicoid adapter for closer focus.

PZO Amar 105/4,5

It's been long time since I bought last enlarger lens. I got very tempting offer. I couldn't resist.
So here it is PZO Amar P105/4,5 with scratch on front coating.
All shots with Sony NEX5+Lens turbo, the combo is great, even on edges.
All wide open except the infinity shot at f8

The Flare

f8

Rodenstock c Heligon 50/2

Rodenstock C Heligon 50/2 was harvested from this Kodak Retina Reflex camera (earlier post about this HERE ) the advance lever got stuck, so I decided to opened it. It turned out like this LOL..

Camera lens mechanism is not easy to handle, very different with previous cameras I opened. The words Synchro-Compur really make chalenge, how to open and make aperture blade & shutter blade controlled. I haven't managed to.. So this is now all wide open.
Dof is so thin, and look at the smoothness..
dimension..

Taking picture of white flower often not easy, some lenses cannot show the detail of flower. This lens does the job nicely

final appearance for now

Petri Orikkor Kuribayashi AC 4,5cm/1,9

This one is from Petri range finder camera

I like this lens. sharpness, bokeh, 3D, colour, contrast...what else..?

Meyer Gorllitz Optik Trioplan 50/2,9 Welta camera

I have Welta Welti I range finder camera with fixed Meyer Gorllitz Optik  Trioplan 50/2,9 lens. It was in good condition. But when I tested with BW 35mm film, it's shutter stuck. I have some picture from the film though, but not satisfied, either because of the expired film or bad metering and missfocus. The only way to get shutter being fixed is disamble the lens.
I could not fixed the shutter blade yet, so it cannot be fully open now. the blade remain like this.
Now here it is the lens performance on digital cam.

sharp at center, soft at edge
