Anyone ever used a M42 to M43 focal reducer with the LS300?
Do you know if there's a problem with flange protrusion?

Thanks

I was going go order one for my Minolta lenses off Ebay. There is a Chinese supplier making them for $70 or so, way less than the Metabones, but they said it would hit the sensor since it is so close.

Too bad.

Not sure about any of the others, though.
