Basic instructions for a handful of camera models would be a big help

Since there are no optical elements inside of this adapter image quality is not affected

I have a few nitpicks none of which reduce the overall rating from 5 stars though1

This adapter does not trigger the little pin for the automatic diaphragm feature on m42 lenses with this feature

This is likely by design and not a defect but just something you should be aware of in case you wondered why that switch doesnt appear to do anything

There are no physical nor electronic connections of any kind and therefore the adapter works best with older lenses that have fully mechanical aperture focus and if applicable zoom ring as opposed to the fly by wire linkage common on modern lenses
