Jupiter-3 1:1.5 F=5cm - a very expensive Soviet fifty dollars for rangefinder and mirrorless cameras. The lens from the review turned 2022 years old in 60.
You can endlessly admire the old technology, as well as the technologies with which it was produced. After all, the lenses of the middle, and even the beginning of the 20th century, can still be used for their intended purpose. Yes, convenience won out, in the end, and all these goodies in the form of manual control of the aperture, sharpness and manual focusing on it are now more likely to repel than push to purchase an old lens. Especially if at a price it is slightly more expensive than its autofocus counterparts in the low-cost segment. So, for example, you can take quite a good autofocus fifty dollars from Canon or Nikon, and if the price is important, then at all, Helios 44 series, and its open aperture will be quite working.

Jupiter-3 1:1.5 F=5cm review with photo examples

If we take specifically the consumer qualities of this glass, then I would say that the lens is not quite adequate on an open lens. Alas, I cannot yet compare him with my German parent, but discovered examples of photos it turned out that things were not so good there either. CZJ Sonnar 1.5/50 is a bit older, but Jupiter-3 is as close to it as possible. The scheme of this Sonnar in 2022 is 90 years old. It is worth adding right away that, focusing on the inoperability of the open aperture, I forgot to indicate that sharpness appears immediately, but only in the center, if the aperture ring is slightly moved so that its petals appear in the space visible to the eye inside the lens, and further, up to f / 2.8, sharpness increases.

Therefore, if I wanted the doubling of the image to disappear into oblivion, while the aperture remained around f / 1.5, I shifted the ring towards f / 2 by a millimeter and the image returned to normal. At f/8 the lens is as sharp as possible, but the bokeh is still interesting if you focus at medium and close distances. At a completely open aperture, the lens turns all glare and light sources into scales, very ugly. But some people might like it. On film, this is offset by the fact that the color transitions are more blurred, and this effect is not very noticeable. On black and white film, during which the Sonnar 1.5/50 was designed, this should not be visible at all, since it only shows grayscale.

On Sovietcams.com Jupiter-3 has 12 known modifications, which differ in the design of the frame, enlightenment and marking. The lens was originally produced with a Contax RF / Kyiv connector, and had a design characteristic of that mount. As you know, adapters with Contax RF can be made using the Kyiv mount and M39 adapter to mirrorless, if you don’t want to look for a ready-made adapter, which, moreover, will cost a lot of money, since the mount itself is very intricate. In this regard, the later threaded Leica M39 variations are not only easier to adapt, but their first releases are as authentic as possible. The lens has a deep blue enlightenment, inherent in all interchangeable optics of the USSR of the 50-60s of the last century, marked in the German manner (Jupiter-3 1: 1.5 F = 5cm - this is just in the German manner, even the red "P" - Enlightened, this is an analogue of "T" - Transparenz). Later ones will be marked as "Jupiter-3 1.5 / 50" and the deep blue color will disappear, leaving a slight reminder of itself.

Jupiter-3 1:1.5 F=5cm review with photo examples

Jupiter-3 can be found produced by factories Jupiter Valdai, KMZ, and the Zagorsk Optical Plant (the hero of the review). It is possible that the quality of workmanship may vary from factory to factory, but I have not seen such information. In terms of ergonomics, there are no complaints about this instance. The lubricant retained its properties, all rings rotate smoothly, and even on the street at minus 10, only a slight increase in the resistance of the rings was noticeable. There are slight traces of disassembly on the focus ring - most likely, the lubricant changed during operation. Aperture values ​​are set steplessly. It must be borne in mind that the settings in this situation are very easy to knock down.

Jupiter-3 taken from a rangefinder camera FED-5V, which is not typical for such cameras. They usually come across with Industar-61 L / D, or other, more mass models. Perhaps the lens was purchased separately, or the camera was replaced with a more modern one. The case is well preserved, the optics are also in excellent condition. Even the coating of the front and rear lenses is not worn, as it happens on fairly used lenses.

Jupiter-3 has 13 aperture blades, and draws circles in bokeh, not nuts, as happens on most mass-segment lenses. However, Jupiter-3 is at one time far from being a mass segment. Based on camera FED and the Jupiter-3 lens, I assembled a low-cost version of the legend - FED-General. Sounds funny, but looks interesting. Expensive-rich looks, pleases the eye.

Jupiter-3 1,5/50 lens diagram

The lens scheme in the GOI Catalog from 1963 is as close as possible to the Sonnar 1.5 / 50 scheme found on the network. The lens used big flints, having a high refractive index, characterized by small (less than 50) values ​​of the average dispersion coefficient.

Jupiter-3 1,5/50 MTF

According to the MTF chart, Jupiter-3 does not have very good resolution. In the center, these are 27 lines per millimeter, along the edge of the frame in the region of 18. At the same time, according to the specifications, it should be 30/14. In practice, the lens has sufficient sharpness, microcontrast, and even when the image is enlarged, at apertures from f / 2 and higher, the details are distinguishable so much that you don’t really believe the graphics. Of course, the sharpness is not razor sharp, but let's look at the marking ring. This is a 1962 release. And the copy tested for plotting the MTF chart was generally released in 1949, or earlier.

Thanks to its maximum aperture of f/1.5, the Jupiter-3 is ultra-fast. At the same time, it has a very low weight. The lenses, unlike Jupiter-8, are actually about one and a half times larger. Particularly the front. Jupiter-3 and Jupiter 8 differ in the optics scheme, but have a common root - a body kit in the form of additional elements is assembled around a generalized triplet. The generalized triplet first appeared in 1916, and Ludwig Bertele's development of the Sonnar circuit was an improvement on the Ernostar lens circuit. Ernostar pioneered the f/1.8 aperture, which allowed shooting in places where flash could not be used. In the future, the main drawback of Ernostar was corrected in Sonnar. These lenses have more contrast and better image quality than their predecessor.

Jupiter-3 example photo

Developed in Capture One, shot on Sony A7. The color of the lens on a digital camera is interesting. Jupiter-3 tones images, and if you do not edit the color in the editor when developing RAW, the white color will have a slight yellow-green bloom. I don’t really like this tinting, so you won’t see this effect in most examples of photos.


Jupiter-3 is a very interesting old lens. It could be recommended for those who love elegance, lightness and aperture, if not for one thing - Jupiter-3 costs quite a lot of money for a mass-produced USSR lens.
