The new camera is a great improvement. Looking closely at the lower portion of the pen as photographed, I think I am seeing a white cast coming from the reflected light off the background. If you could elevate the pen above the background then this reflected light should be reduced. It may just be me seeing things. If you do not see it then please disregard this post.
The focus and wb is greatly improved in the new photo. the two new pens look very good, the focus is spot on, the lighting is very even and the exposure is right. Congratulations.
