Aperture Series: Sidelit Barn at DeChambeau Ranch (M240)
This example shows the superb contrast possible with the 18/3.8 Super-Elmar-M ASPH and also allows an evaluation of the sharpness gradient (field curvature) by dint of the near-to-far grassy areas. In a related vein, the slight “swing” (view camera term) as noted in other series is actually a plus for this particular subject because it biases sharpness to the distance on the left side, at the cost of less-good sharpness on the right side.
Interesting diffraction effects are observed on the metal roof siding; see crops. Also, color aliasing is in abundance (a Bayer matrix sensor behavior and not a plus).
This series includes crops at f/6.8 and f/9.5 and f/13 in part to evaluate quality in the more stopped-down ranges of apertures, the concern being micro contrast loss from diffraction at f/9.5 and f/13 in particular.

Diglloyd Guide to LEICA contains in-depth coverage of Leica M system cameras and lenses, with additional coverage of Leica M Monochrom, Leica Q.
Special emphasis is placed on Leica M lenses and certain Zeiss ZM lenses.
- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly the Summilux/Summicron/Elmarit choice and/or Zeiss ZM.
- Make better images, a sort of “cheat sheet” saving yourself months or years of ad-hoc learning. Processing parameters are discussed and shown.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
