I purchased another Rainbow Imaging Minolta to NEX adapter, to use with my old Minolta Celtic 135mm f/2.8 MC lens. Using that combination on my NEX-7 gives me a 202mm f/2.8 lens, which will be VERY useful. This was just a quick, hand-held test shot, to make sure everything was working correctly. Manual focus was very easy, using the camera's focus "peaking" feature. Aperture priority, with a +1/3 manual exposure compensation. Standard color. Automatic white balance.
