This review shows the lens JUPITER-12 1: 2.8 F = 3.5cm P s external mount Contax-Kiev RFmanufactured at the Arsenal plant, Kiev, Ukraine, in a 'white' metal case with serial number 602031.
Radozhiv already has a review of such a lens, but in its other modification - JUPITER-12 2,8 / 35.
Lenses JUPITER-12 2,8 / 35 and JUPITER-12 1: 2.8 F = 3.5cm P differ only in trifles:
- different release times.
- different color of the frame of the body, different frame of the rear lens unit, different style of marking with the aperture values, different spelling of the lens name.
- different factories manufacturers. The lenses JUPITER-12 2,8 / 35 in a black case were produced at LZOS, JUPITER-12 1: 2.8 F = 3.5cm P lenses in a white case were produced at the Arsenal plant. There are many more different modifications of Jupiter-12, released in other factories, with different body frames and not in bayonet version.
- different optics enlightenment (see visual difference). This distinction is considered one of the most important. Later 'black' lenses have better color rendering and better contrast than 'white' ones. Despite the absence of the red letter 'P' at JUPITER-12 2,8 / 35Both lenses use simple chemical enlightenment.
On the copy from the review, the diaphragm ring rotates very tight, most likely due to its damage. But still I want to note that the assembly at the white JUPITER-12 1: 2.8 F = 3.5cm P of the Arsenal plant is better than the black JUPITER-12 2,8 / 35released at LZOS. At the same time, the image quality isblack'options are better.

The lens is very weak at F / 2.8 in terms of sharpness, especially at the corners and edges of the frame. The sharpness at the edges returns to normal only after a strong close of the diaphragm. There may be a loss in image quality, including sharpness at the edges and corners of the frame, due to color shift. Like 'black' version lens, JUPITER-12 1: 2.8 F = 3.5cm P is very afraid of flare.
Source files can download from this link (32 photos in the '.ARW' format, 728 Mb). All photos were shot on F / 4.0. On camera Sony a7 I used a lens with a homemade adapter without any problems. Part of the photo was taken in APS-C cropping mode.

Maybe someone will come in handy, on the Canon EOS M it gets up normally, it passes into the frame frame without problems. I myself have a U-12 under L39 / M39 (early LZOS 1961 white), but it seems that Kiev / Contax RF will also get up without problems.
That's it, I understand - I'm running after M-coy)))
And yet, yes)). On a digital camera, you probably shouldn't want good landscapes from him. But as a portrait shirik, quite a yes ...
Poison everything)
on open
And in general, yes, in Soviet times, wedding bombers appreciated this lens, though in the Kiev-4 application
And even if you screw in a hood at 40.5 (aliexpress / ebay to help) it will be very convenient to control the diaphragm
Are you from Vinnitsa? Tell me please, where can I get glass here?
