VEGA-12Б or 12B 2.8/90 P6 mount

My first attempt to feel medium format sensation is between CZ Biometar 80 or Volna 3. I was watching some listing on the bay of them. Then A friend offered me to relayed this lens from Eastern Europe, I have no information about it before. I just trust my good friend (thanks again Stefan). He said the lens is in nice condition. Yeah it's true.
Before lens arrived, I ordered adapter from chinese ebayer, P6-EOS. I combine it with EOS-NEX adapter in my little NEX.

• Closest focus is 0,6 meter. farthest before infinity 10 meter
• 6 'gold' blades
• filter ring is 58mm
• all metal body like other old Russian

This lens is awesome. sharp @ wide open.


great for sunset & silloute

not bad for birding


even my wife shot well

Schneider Kreuznach Xenar 50/2,8 Compur Retina

Still playing with famous German factory, same mount with my other Schneider this Xenar looks similar to Schneider Kreuznach Curtagon 35/2,8 Compur Retina 
Retina was brand of rangefinder camera made in Stutgart, Germany. Later they made also SLR.
I don't know whether this lens for rangefinder or SLR yet.
According to previous owner, this lens fits on Retina IIIs rangefinder.  It's a tiny 4 element lens (with a tessar formula I guess), Some fellow from mflenses said Xenar has same formula with Zeiss's Tessar



all wide open




Look at ring bokeh below, remind me to Meyer Trioplan 100/2,8


this isn't wideopen, damn sharp

Takumar 17/4 Fish eye M42

When I spot this lens on ebay, I never heard nor read about it before. But I'm interested of it small size, that will match in my NEX and Takumar is guarantee of good lenses. So I bid. only me, I won.

I used Panorama mode on Nex5

closest focus 0,2 meter to   only 2 meters. So beyond 2 meter is infinity, make it easy to take landscape.
Too bad There's no front cap.
It's not a lens for low light, very dark in viewfinder.
On daylight it takes advantage, it sharp!

heavy crop, macro with this lens

Video taken with this lens ad Sony NEX5

This  tiny lens is for Kodak Retina cam, not common lens in Indonesia. It can be attached in DSLR. I have the DKL-Canon EOS adapter for it.
Funny thing for me at first touch, there's no aperture ring on lens! I was confused. My friend told me that aperture controlled by the adapter.
this picture is the lens without adapter

Closest focus dustance is 0,9 meter

aus Jena Flektogon 35/2,8 M42 Black

I had my early Zeiss lens last year. It's CZ Jena Flektogon 35/2,8 silver/alu finish. It was sold.
Now I just received Black version branded with  aus Jena.

Comparison between Flektogon 35/2,4 & 35/2,8 ( this lens)
 Flekto          closest      farthest b4 Inf blades filter               coat    aperture
 35/2,8           0.18            4                  6        49mm            -       2.8-22
 35/2,4           0.2              5                  6        49mm            MC  2.4-22

From that table we can see that this lens has shorter close distance. It's effect on macro objects.
Multi coat on f 2,4 one is reallly make different. produce more rich color better contrast etc. Well... the price is double, sometimes more.
