These examples explore the world-class optical performance of the Leica 75mm f/2 APO-Summicron-SL ASPH when used on the Panasonic S1R in Multi-Shot High-Res mode. I wanted to see if I could obtain high sharpness images near dusk, and just how much detail could be captured in subjects that have more detail than the camera can normally faithfully record.
Images at up to 141 megapixels. Prepare to be impressed.
