uncoated 35mm lens?

[daniel buck]

You might find the Leitz 2.8cm f6.3 Hektor (pre-war) uncoated would meet your requirements.Most of the lenses were uncoated.The coated Post-war examples are rare and expensive.

Thanks for the suggestion! I see a few on auction, but not at prices I want to pay for such a lens. I'll keep my eye out for one at a better price/worse condition.
