Yashica Auto Yashinon-DX 1: 1,7 f = 50mm is a very good fifty dollars. He has several brothers such as the Yashica Yashinon DS-M 50 mm f / 1.7 and the Yashica ML 50 mm f / 1.7. The optical design is very similar to the Planar.
В Promotions from Radozhiva №2 it was the Yashica 1,7 / 50 that was the intended lens, and many participants correctly expressed their opinions in the direction of the Planar 50mm F1.4-1.8. Interesting, but you can find information that Yashica collected some Carl Zeiss lenses.
The Yashica 1,7 / 50 focus ring rotates about 200 degrees, focusing is very smooth and light. Manual lenses usually have a tighter focus ring. The focus ring on the Yashica 1,7 / 50 can be rotated with one finger and at the same time it is well fixed and does not spontaneously spontaneously. When focusing, the trunk of the lens is extended by a centimeter.
The lens has a large enough aperture with aperture F / 1.7. This is 1.12 times larger than F / 1.8 and 1.47 times smaller than F / 1.4. When closing the diaphragm in the blur zone, you can get hexagons, since there are only 6 aperture blades. The lens has an aperture ring for switching the aperture control mode M \ A, which makes it possible to use it on modern central controllers without problems. Also, the lens has a depth of field and focusing distance.
Image quality
The lens gives a good contrast image. Sharp from F / 1.7. The drawing is 'soft and pliable'. The bokeh of the lens is slightly swirling, the so-called "cat's eye" (the discs of confusion are similar to lemons, the eyes of a cat). In general, you cannot complain about the quality.
How to use with modern cameras?
Lenses with mounting thread M42 (M42 X 1 / 45.5), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), for this it is enough to choose the right adapter (adapter). You do not need to carry out any additional steps to modify the lens.
The cheapest adapters can be found at Aliexpress.com... There are adapters (adapters) with a chip that provide more convenience during shooting, usually chips are used to confirm focus and / or metering exposure, and form the correct EXIF. The chip does not affect the image quality in any way.
For some SLR cameras (for example, with the Nikon F-mount), you need to use adapters with a corrective lens, which allows you to focus correctly at all focusing distances. For any mirrorless cameras, such a lens is not needed, and the adapter is a simple decorated hollow metal tube with an appropriate mount.

Personal experience
Yashica 1,7 / 50 is a good fifty dollars; it doesn't twist as much as Helios, it looks more like Carl Zeiss Planar, but for a more modest price. Focusing and working with the lens is very easy and enjoyable. By the way, Nikon owners do not need to think that the designation DX in this case, it somehow affects the work with FX, DX cameras. A prefix Cars it doesn’t mean the presence of autofocus, but only speaks for the ability to automatically control the iris.
Conclusions
Yashica Auto Yashinon-DX 1: 1,7 f = 50mm is an excellent fast prime with good image quality. Recommend.

People. Are contax / yashica and contax / rf mounts the same or different?
I want to buy Helios 103 with contax / kiev mount. Ali is full of cy / nex adapters. And I'm wondering if such an adapter is suitable for a sony a6000?
These are different mounts. C / Y SLR cameras, Rf rangefinder
Bought recently. Checked today. It’s still not very sharp on an open hole, but at 2 it’s already what you need, and the bokeh practically does not change from cover to 2. I also have Jupiter-8 2/50, and so the image from Yashiki with a hole of 1,7 is exactly like from Jupiter to 2.
Backlight kills the picture completely, I am attaching a photo, on the second I covered the lens with my hand
