These examples were taken with Leica 24mm f/1.4 Summilux-M ASPH.
If you’d like to visit the areas shown here, consider one of my photo tours for a personalized small-group experience.
My evaluation sample had a backfocus problem even worse than with the 21/1.4 Summilux-M ASPH, enough to ruin the comparisons I had shot (I had no time to test before leaving for a trip). Accordingly, sharpness tends to be biased slightly to the rear in these examples, with a slight loss of crispness in areas closer to the camera, contrary to my intentions. The effect is modest, and probably would go unnoticed to most observers, and the forward field curvature mitigates this issue for certain images. Remember, it’s matter of centering the zone of focus where desired, and with 3D subjects at f/8 one can get away with a lot, since the zone is fairly deep once one gets a bit distant from the camera. Had I known in advance, I would have biased focus slightly forward.

- 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.
