I do have an UV/IR cut filter, but did not use it for this shot. Though the image shot by M8
has colour shifts at the corners even using some of 6-bit codings, so I might have to make
a CornerFix template file or a correction profile for Capture-One program. No time for this.
(with M8 lens' EFoV is equivalent to 24mm's, can use Zeiss 25/28mm view finder)
