RE Topcor 5,8cm/1,8 Tokyo kogaku

First of all, the lens has some fungus. I haven't time to clean it. It's quiet prone to strong light, cannot tell if this is because of fungus or not, until it's being cleaned.

Using Lens turbo on NEX5, the flare is present without lens turbo too. over all sharpness is improved using lens turbo.
