In Guide to Leica I have added eight lens rendering aperture series for the 24/1.4 Summilux, designed to show the sharpness, bokeh, optical behavior and so on. Starting wide open at f/1.4 and running through f/16 for each aperture. See also the 24/1.4 Summilux vs 24/3.8 Elmar comparison.
Each of this series is presented in standard resolution, HD and ultra-HD* sizes for viewing pleasure (the ultra-HD size is best used only a very large displays, such as a 30" monitor or MacBook Pro with Retina display). The Ultra-HD size is useful with scrolling for evaluating image quality as a whole at a size very close to actual pixels).
For the Leica M Typ 240, the Ultra-HD size is 64.4% of actual pixels (linear), so it is a terrific way to evaluate the total imaging style gestalt of the lens and camera.
* Ultra-HD = 3852 pixels wide X ~2568 pixels high on this site. The 4K display standard is coming in 2014. As per my high quality standards, I want this site to be at the forefront, just as it was the first site on the web to embrace retina grade images and still remains the only site to do it properly.
