This is for those interrested in mounting arcane, non-FT/autofocus lenses on their cameras.

It's a free ebook from 2005 I think with his subjective rating. I came across it when looking at the Voigtlander Nokton 40mm f 1.4 that some people seem to enjoy mounting on their mFT camera... It's a performer and is smaller than any other lens.

Note: That 40mm lens has an interresting bokeh but most importantly il looks pretty sharp and results are very nice: example, example.
