Neat pen Dave,small problems can be overcome one of them being photography. Pictures are determined not by the quality or cost of what you use to achieve them. The rules of sharpness and light to capture the image require a little forethought and mechanical application. It pays to have a means of holding the camera steady,the pen adequately lit,well worth the time spent. If it worries you it then worries us. Using a plain background helps avoid distraction and competition in focussing.
Kind regards Peter.
