In short
MINOLTA MD ROKKOR-X 50mm 1:1.7 is an old, fast, manual-focus fifty-fifty lens designed for film cameras, produced since 1977. Later replaced by a similar lens with more compact dimensions.
MINOLTA MD ROKKOR-X 50mm 1:1.7 is primarily interesting for its good work at F / 1.7. By the nature of the image, it is similar to many other similar fifty dollars built according to the 6/5 scheme. A very popular autofocus lens is also built on the same optical scheme. MINOLTA MAXXUM AF 50mm 1: 1.7 (22) AF LENS 50.
Versions marked 'ROKKOR-X' rarer and optically more perfect. But head-to-head comparisons indicate the identity of the optical characteristics of lenses with different markings. Lenses marked 'ROKKOR-X' were only shipped to select countries in North America, while regular 'ROKKOR' lenses were sold worldwide.

Classic spoiler for fifty dollars: The creative potential of such a fifty-kopeck piece (lens with a focal length of 50 mm) can hardly be overestimated. It is suitable for a wide range of photographic tasks. Amateur photographers often use it as a portrait lens. The fast prime is an excellent addition to any standard kit lens. Aperture F / 1.7 more than three steps wider f / 5.6 aperture, which is used in 'dark' kit lenses at the long end. In numerical terms, this means that Minolta AF 50 / 1.7 is approximately 11 times brighter whale mirror lens Sony DT 3.5-5.6 / 18-55 SAM or mirrorless Sony FE 3.5-5.6 / 28-70 OSSwhich use a maximum relative aperture of only 50: 1 over a 5.6 mm focal length. The calculation of the difference in the relative aperture (count the aperture) is performed elementarily: (5.6 * 5.6) / (1.7 * 1.7) = 10.85, which is rounded to the value '11'.

Assembly, control, focus
Lens body It is made qualitatively. The focus ring has an anti-slip insert made of hard rubber or similar material.
The diaphragm consists of six blades and forms a regular hexagonal opening.

MINOLTA MD ROKKOR-X 50mm 1:1.7 uses small filters with a diameter of 55 mm. On the body there is a focusing distance scale and a depth of field scale + a label for working in the infrared spectrum.
Focusing ring MINOLTA MD ROKKOR-X 50mm 1:1.7 rotates approximately 180 degrees (half a full turn). During focusing, the trunk of the lens travels forward, but the thread under the filters does not rotate. Focusing is performed by moving the entire lens block. The minimum focusing distance is 45 cm, which is the norm for such lenses.

How to use SR/MC/MD mount lenses
To use a MINOLTA SR, MC, MD mount lens on modern mirrorless cameras, you should use the appropriate adapter:
- Canon RF/RF-S: adapter SR/MD/MC -> RF/EOS R
- Canon EF-M: adapter SR/MD/MC -> EF-M/EOS M
- Sony NEX/ILCE/FE/E: adapter SR/MD/MC -> NEX/ILCE/FE/E
- Nikon Z: adapter SR/MD/MC -> Z
- Panasonic L / Sigma L / Leica L/T/TL: adapter SR/MD/MC -> L
- fujifilm x: adapter SR/MD/MC -> X/FX
- Samsung NX: adapter SR/MD/MC -> NX
- Micro 4 / 3: adapter SR/MD/MC -> M4/3
- Nikon 1: adapter SR/MD/MC -> N1
The adapters are compatible with SR, MC and MD mount lenses and these mounts are backwards compatible. But the use of lenses with a MINOLTA SR, MC, MD mount on SLR cameras is difficult due to the long working distance. In such cases, a corrective lens adapter must be used, which will degrade the image quality.

Good manual lens. Gives a clear picture. Easy to use)
great wide Arcadia and Natalia for their breathless work and wonderfully look around the objects.
There was such a lens, in general I liked the picture, but there was a fungus in the middle, so I took his friend for MINOLTA AF 50mm 1: 1.7 even a little cheaper at a flea market than this one 2 years ago. It seems so far that from the “new” photo it’s a little worse, although there is no fungus ..
I have this lens on a Minolta X-300 film camera, but I can’t put it on a Canon 5D. The adapter comes with an additional lens and there is a suspicion that this lens can spoil the picture. Does anyone have experience with the Minolta MD-Canon EF adapter?
The lens always spoils the picture
It turns out that you need to buy a mirrorless camera for the convenience of using old lenses?
Everything else is half measures - such a conclusion suggests itself from your reviews with Rodion.
Why? You can cut these lenses and use them with success.
I still bought a mirrorless camera, largely in order to use old optics with adapters. Thanks again for your reviews!
Peaceful sky.
“Does anyone have experience with the Minolta MD-Canon EF adapter?”
Hello,
quality is relative
I took a photo for you in the specified bundle, you can evaluate it yourself
Canon + MD-EF with lens + open rockcore (DPP4 conversion + resize up to 6mp)
Good luck
Yuri, hello!
An additional lens, essentially unnecessary and superfluous in the optical scheme, of course, will spoil the picture. But, there is one thing, but. Gregor_S correctly wrote that quality is a relative concept. Having photographed the test table, you will surely be horrified by what you see, and having photographed the plot in which the central place in the frame is the main thing, you will be pleasantly surprised by a completely unusual, pleasant picture in all respects. I have an adapter with such a lens in my arsenal, as well as several very worthy Minolta lenses. All fifty dollars of different luminosity and different years of production. But, alas, I haven’t used them for a long time, they are gathering dust on a shelf in boxes. I'm adding an old photo from ten years ago. Photo without processing, only resize. Canon 7D plus Minolta with adapter. But I don’t remember which Minolta, 1:1.7, 1:1.8 or 1:1.4.
And here's another one, I found Minolta with “mushrooms” in the archive! Sold it a long time ago at auction. Actually, Minolta and photos that were obtained with a lens and “mushrooms” :)
A photo…
beauty ... I'm talking about mushrooms)
Yes, the beauty is still the same :) But, I have had even more terrible mushroom seedlings on the lenses. I read somewhere on the Internet that the fungus on the lenses is not so difficult to get rid of. But, I did not bother and sold all the "mushroom" lenses. People bought, so the problem is solved.
hello
I heard that it all depends on where exactly he settled. If in gluing, then probably everything is quite difficult.
On the other hand, it probably adds its own unique pattern)
Getting rid of is not difficult, rather expensive if outsourced.
It takes a long time to explain what's what. Basically, if enlightenment does not move out, then on the islands.
In gluing, sticking usually happens)))
With a great desire to create and a lot of free time, objectively, this can also be eliminated. Balms are usually not very persistent.
Individually.
Just the price of a quality repair of an inexpensive lens turns its cost into the cost of a modern new analogue at least. Is it worth it?)))
The fungus is removed with hydrogen peroxide and some kind of soft cloth, without pressing, and slowly wipes off. But you need to know and feel this. I knew a specialist who bought a zoom lens (Zuiko 35-105, covered in fungi) for spare parts and washed it, you need to have patience. He then showed such sharpness that I brought him slides for reproduction (late 90s), so the photos were published in the magazine “Photomagazine”. Well, this is a good specialist, from the defense industry.
I had one too)
I also had one)
One more photo…
And the cups on the open ...
Nikolai, the glass was apparently beautiful)))
I’m just looking at the photo and I see my autofocus Minolta from the 86th)))
Minolta MC Rokkor-PF 50mm 1.7.
Using water peroxide will prevent fungus on the lenses. They're all Cossacks. Peroxide can be used to remove just a little bit of the lens from the effects of the fungus. After three or four years, it will continue to operate, and if the lens is kept in a dry place with occasional temperature changes, even faster. The fungus can be eliminated either by chemical means, more than “meat sponge”, or by ultraviolet treatment. Tse s vlasnogo dosvidu. In this case, mothers need to be aware that the fungus does not exist on the lens, but rather on the lenses, settling between the lens and the lens. This chemistry can change not only the results of the vitality of the mushroom itself, but also its enlightenment.
