In Photo 4, vignetting occurred as the zoom lens was driven beyond the focal length of 80mm; the telephotographic end of CP8400 is 85mm in focal length. In 4, the focal length is at 81mm.

The optical quality of CP8400 at the middle of its zoom lens range is excellent. In this, probably DCs of other makes suitable for the purpose of digiscoping can't come any closer.
