MTF: 24mm f/3.8 Elmar-M ASPH
MTF of the Leica 24mm f/3.8 Elmar-M ASPH is outstanding even wide open, but this is a computed (not measured value) fantasy MTF value that is neither a real measurement rom a real lens, but worse, does not take into account the sensor cover glass of a digital camera. So the chart is at best misleading for a real camera, particularly the 40MP Leica M10-R. Edge performance in real images is notably inferior to what the MTF chart claims.
Stopping down to f/5.6 produces results that are better than either of its two slower siblings. This lens shows only very mild field curvature*, and thus should be preferred for any planar (flat) subject matter. See the comparison against the Leica 24/2.8 Elmarit-M ASPH.

- 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.
