Meyer Optic Trioplan N 100/2,8

Some fungus inside, let it be...

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.

Images below were taken with this lens and Sony NEX5

You won't get bokeh thing with this lens, it has 0,3m MFD, Flektogon 20/4 has closer. but this lens sharper I think.

Tokyo Kogaku Topcor RE GN M 50/1,4

I had 135/3,5 of this brand, it's great lens. Curious of famous brand Topcon, I was lucky to get this lens in reasonable price. it has fungus and not mint condition, but I'm happy with it. ebay price is very high of this rare radioactive lens.

I heard this lens was the latest product of real Topcon before Cosina rebranded.

Tokyo Kogaku Japan made great lenses. price of their lenses increase everyday.
