Here is a dead bee/fly up close (with some fancy macro lens and equally fancy lighting set up). The NEX sensor was on a tripod and I used the 10s timer mode. Only after stopping down the lens to see diffraction effects (as indicated by the dust on the sensor), there is some details starting to show up. This image is after turning off all the destructive things like noise control (which was set to minimum), DRO and the like. Snapped at ISO200 and it is the entire frame.
