Review: K&F Quality - Quite the decent price and quite the solid build, has a minor amount of play with my Helios lens but seems minimal and allows me to use all of my M42 lenses without trouble. Well packaged, nice and shiny! P.s the colour match of the orange to the sony flange is also very close and matches well.
Review: New life for old lenses - If like me you have some old M42 mount lenses gathering dust then this adapter can give them a new lease of life. It is as solid as a brick feels like quality.
