Vivitar 28mm f2.8 - a photo on Flickriver

Vivitar 28mm f2.8

Another eBay bargain. A manual Vivitar 28mm f2.8 K mount. Including a Vivitar x2 converter for £18.

According to the Great Vivitar 28mm Bestiary this is a Komine made variant - K03.

Came infested with fungus. Fortunately it disassembled very easily and cleaned up beautifully. Cold cream really does clean lens fungus.

Finally I got around to trying it out. It took a while to re-learn old skills of manually focusing and aperture setting - I've not done this for over 20 years since the days of Olympus OM-2.

A bit soft at f2.8 but sharpens considerably at over f4. No CA to speak of and hardly any barrel distortion. Colour is a bit on the blue side, easily fixed in post-processing.
