I need some help with this. I sold my Olympus 9-18mm here on the forum. The buyer sent me several PM's today and insists the lens has serious flaws. He says he got another 9-18mm lens from a friend and it performs much better. So, below are his own comparison shots that he labeled Lens "A" and Lens "B". Without any of you being biased in any way by knowing what his complaint is or which lens is which, does anything stand out to you that says one lens is behaving far worse than the other? I'm honestly trying to figure out if I completely missed something here or if the lens got damaged in shipping, but I'm just not seeing it. Please note, exif info is correct and there is one more piece of information I'll share about it after I get some feedback. Lens A Camera: E-PL5 9mm 1/320sec f8.0 iso200 0 EV Lens B Camera: E-PL5 18mm 1/500sec f11 iso200 0 EV Lens A Camera: E-PL5 10mm 1/1600sec f4.3 iso200 -0.3 EV Lens B Camera: E-PL5 9mm 1/160sec f7.1 iso200 0 EV So, do you think one of these is bad or is this guy acting strange.
