I have recently bought a vintage lens 135mm f2.8 from Auto Revenon, with m42 bajonet. And to mount it on my nikon d7000 I need to install an adapter with correction lens. Otherwise the focus range will be to short and it can't reach infinity. I have read that is because of the distance from the lens to the sensor.
And I would like to know if I also need correction lens for other vintage lenses, especially for minolta md?
