Prewar Carl Zeiss Jena Sonnar 50mm 1.5 - better coated alternatives?
I have a beautiful Carl Zeiss Jena 50mm 1.5 lens for Contax RF (non "T") that I use on a Sony A7 II. I love the lens, I love the way it renders, It's a very nice copy.
However, the one thing that makes me worry about this lens is flare. As this is an uncoated lens, it flares a lot. Not only classical sun flares, but practically every shot wide open has some nasty blueish flare across the frame.
There are coated variants of this Sonnar lens: the later coated war and post-war Carl Zeiss Jena Sonnar "T" and the Zeiss Opton Sonnar "T". In theory, because of the cemented triplets in the CZJ Sonnar, there shouldn't be much of a difference with coatings.
Does anybody of you have a coated copy of this lens and could make a comparison with an uncoated copy?
Are there similar lenses that cope better with flare that you can recommend?
