K-8x
52mm red lens filter
LZOS, USSR
with box

Excellent condition. There are no scratches, cleavages, fungus. Box is original.

I took test photo with this filter set on "Jupiter-37A" lens and DSLR "Sony A-100". Test images are #4 (with filter) and #5 (without filter).

Lens "jupiter-37A" is not included.

This filter has 52x0.75 mount and is designed for popular USSR lenses: Jupiter-37A, (MC) Helios-44M-4, 44M-5, 44M-6, 44M-7 and others.

This is a classic red filter with very strong power. When taking photo of landscapes this filter will eliminate haze at long distance. When taking pictures of flowers at black&white film this filter will intensify the contrast between green foliage and flowers.

Inside the box there is an inscription in Russian: "When using filter K-8x aperture must be changed to minus 3 steps".

Also this filter can be used to simulate the usage of infra-red film. Pictures taken at daylight will look like in the night.
