I would like to improve the image quality of my photos. I presently have a E-PM1, how much difference in image quality is there between the E-PM1 and the 16 megapixel sensor of the E-PL5. I've also debated getting a new lens but I suspect that it's better to buy a refurbished E-PL5 and sell my Pen Mini. The problem I have is no one sells these cameras here so I can't try them out. I have three native lenses the 45mm, the kit zoom and the 40-150mm telephoto zoom. I also have a 50mm Minolta f3.5 MD Macro and a Vivitar 75-205mm zoom. Any advice out there.
