1966 The Ruby 1 was adapted for the M42...there are scuffs, scratches and transparent spots on the front glass, there is a chip on the side of the inner glass on the photo tests, I did not see any defects...there may be vignetting around the edges in the full frame...on a standard adapter, the labels will be at the bottom (see the example on a modern camera) you need to adjust your adapter if it is adjustable, then you can put the labels in the center ...!! Attention, the Zenit 6 camera is a bonus - you need to adjust the shutter speeds in the camera, it does not work correctly with a bonus...the set includes two filters and a unique adapter made in one copy and an adapter for the adapter in the photo, without caps...added examples: a photo with a boat on a crop, red leaves on a full frame...I recommend covering the aperture on the lens first, then focusing so that more photos are obtained
