I shot some photos of my turntable rig with my E-M10 and 12-40. There were a few questions lingering in my mind regarding resolution at smaller f stops and ultimate enlargeability of the M43 format. The various comments on this and other forums about the significant loss of resolution at smaller apertures than f8.0 and inability to produce really big images without pixilization ruining them was to be personally tested with these photos. The first photo is the whole frame converted directly to resized JPEG from RAW with no post processing. Exposure was 2.5 sec. at f16, ISO 100, -1.0 EV exposure correction in camera. Focal length was 40mm. The second photo is the area of focus cropped but not resized. I defy anyone to complain about M43 resolution in general or small aperture capability of the format specifically. Diffraction be damned!
