JUPITER-8M 2/53 is a modification of the previous version of the lens 'JUPITER-8' - JUPITER-8M 2/50.
JUPITER-8M 2/53 and JUPITER-8M 2/50 do not differ in anything special. The new version only has a slightly modified case frame. The real focal length of the JUPITER-8 / 8M series lenses is about 52,5 mm, therefore the new version in its designation has the parameters '2/53', similar to the '1.8 / 53' HELIOS-103 1.8 / 53. JUPITER-8M 2/53 refers to one of the most recent modifications of this lens.
JUPITER-8M 2/53 looks like this:
Image quality differences between JUPITER-8M 2/50 and I did not find JUPITER-8M 2/53.
On camera Nikon D80 I used the lens with an adapter ring M42 - Nikon F (aka KP-42 / N) and an extension tube for M42, 1 cm thick. The lens is 'recessed' in the extension tube and fixed with tape. The ring is screwed into the M42 - Nikon F adapter, after which everything is installed on the camera :). In this state, the focusing distance is about 20 cm.
Instead of a conclusion:
More than half a dozen JUPITER-8 / 8M lenses have visited my review. If there is a choice which lens to take, then I would focus on the early versions of Jupiter-8, that's why:
- The original Yu-8s have smooth aperture adjustment, which is useful for shooting movies.
- The diaphragm ring in the old Yu-8 rotates quite easily, it can be moved with one hand. In the Yu-8M, the ring rotates tight, for this you have to hold the lens with one hand, and change the aperture value with the second. Because of this inconvenience with the Yu-8M, it’s easier to bring down the focus.
- The diaphragm blades of the Ju-8 form a more regular opening than that of the Ju-8M, which has 'circular saws' at half the values. In addition, the aperture blades of the Yu-8 are more opaque than those of the Yu-8M.
- Yu-8 has an optical design closer to the original Sonnar 1: 2 f = 5cm Carl Zeiss Jena. Yu-8M were made according to the same optical scheme, but with a different element base (the difference is shown in the review JUPITER-8M 1: 2 F = 5cm P).
The advantages of the U-8M can be attributed to improved clarity, slightly higher contrast in the images and a little less yellow-green tint. In addition, the Yu-8M is a newer lens, which theoretically makes it possible to find it in a more 'alive' state.
