How good are Russian Filters?

[chip j]

I've bought a couple on ebay & they seem to be fine, but I haven't used them yet.

 

[Helios 1984]

I have a few of these in 52mm size, LZOS if I remember well. I use them with my Helios 58mm & EF 50mm f/1.8, I haven't had any problems so far.

Well, should they be less than their lenses?

 

[faberryman]

They are colored glass so should work fine.

The KMZ ones I got are not coated (if I remember right), but 90% of all my non soviet filters are not coated either.

I thought ALL filters of the modern era, except old Vivitars, were at least single-coated.

 

[AgX]

Do you consider me modern...?
I buy my filters out of the rummage box.

But yes, my filters are from a period when lenses had been coated already for decades

No filter on left, soviet filter on the right.

HOLY SHIT!!

I wonder if the old Arsenal filters are that awful??

Puzzling. But a incidental result does not make a test.

(The author uses a per definition not spectrally neutral filter and is surprised by a color cast.)

 

[faberryman]

HOLY SHIT!!

A great reason not to use a UV, Skylight, or other filter unless you have a specific purpose for doing so.

I have never had a Russian that I needed to filter.

Here is an excellent, scientifically conducted, test of UV filters by various manufacturers.

For that you’d need a “Russian minus” filter. Unless you want him/her to look brighter.
