Hello,
After saving up for two years, I have finally taken the plunge and bought a used MP-E 65mm to get into really close up Macro photography. I bought the lens from a very reputable UK dealer with a good warranty and returns policy, and have spent the last few days testing it. Before this I used mainly the canon 100mm 2/8 USM, which I have been really pleased with.
As most of you probably know, it's quite a leap getting used to the focusing DOF etc that this lens requires. I tested the lens on various objects, the last of which was a dark blue structure against a white/yellow background. Looking at the live view screen, I could see some really weird 'ghosting' effect going on - almost as if there was a shadowy copy of my object following it around
I took some test shots (handheld) at F5.6 ISO 800 1/100, this one at an approximate magnification of 3.5. The effect is only slightly visible on these images, as a sort of wide shadowy border in some places. Now I am unsure of what to make of it. The lens was in a very good condition, with little use and only one tiny cleaning scratch to the front element as well as a tiny amount of dust inside. It has not obvious scuffs, scratches or other faults, everything moves smoothly and has not been tampered with.
Obviously my focusing is still nascent, I am getting some good shots, but not great and my usual methods for evaluating a new lens won't work in this scenario. My question is now: Is this fringe Chromatic Aberration? My incompetence? Some other optical phenomenon I am unaware of? A result of the tiny front element scratch? Other internal (not immediately visible) damage to the lens? Should I send it back and save up for a new copy instead? Help!!!
