What size filter thread for I-50, I-22

[iggers]

What size filter does the fixed Industar-50 take? What about the collapsible I-22? Where can I buy inexpensive hoods for these lenses?

Same as the Elmar it was copied from. It's a A36, 36mm push-on filter. You're best off doing a DIY hood from a plastic bottle.

Thanks. Are there particular plastic bottle types / brands that you recommend - such and such brand juice, that sort of thing?

The cup of Tmax developer is almost perfect. Cut its bottom carefully and at minimum, and from there reduce it slow slow so that it will attach to the lens with maximum strenght.
