Review

The RUSSARs on the market other than the LOMO brand are available in black and silver, but most of them are noticeably tired on the exterior due to age-related deterioration. The lens barrel of this lens appears to have been rebuilt and is a beautiful shiny silver color.
The lens is old and dark, starting at f/5.6. The filter diameter is 49mm, and although it is desirable to attach a filter to protect the impressive convex front element, attaching a filter has the disadvantage of not allowing the aperture to be moved.
The minimum focusing distance is 0.5m, unchanged from the previous version, which is regrettable.
It is nice that the symmetrical lens has no distortion, but when shooting with a digital camera, a large color cast may occur as with the HOLOGON 16mm, Super Angulon-M, and BIogon-G 21mm lenses.
Color cast is more noticeable in blue sky and dimly lit scenes. It is not noticeable when converted to monochrome, so when shooting with a digital camera, I use it on the assumption that it will later be processed in monochrome.
The actual images are intentionally put up as color casts, and we hope you can see how it looks like this.

Of course, if you use the smaller sensor size M4/3 (Micro Four Thirds) or APS-C sensor, the color cast problem will no longer be an issue. Since the lens is compact, it looks like an old compact camera when attached to a small camera body, making it a great snapshot camera.

The gallery posted the shooting results of Micro Four Thirds and HASSELBALD X2D.
The large sensor size of HASSELBLAD This seems to be due to the new sensor. This is a happy event that will increase the frequency of lens usage.
With a wide angle of 20mm and a maximum aperture of F5.6, it is almost a pan-focus lens, but the problem is that it is difficult to clearly judge the focus position even when magnified with the EVF.
