Leica Q Focusing Issues

Autofocus coverage

Autofocus sensor coverage is excellent, offering focus points right out to all four corners. Unfortunately those focusing points are rather large (did I miss something?!), and far too large an area for selective focus (for example, encouraging the camera to focus on the iris of the eye).

Because the focus area is so large, it’s impossible be pinpoint the desired portion of the subject. Testing this theory repeatedly revealed that the Q can be shown to focus on the subject or the background depending on where focus starts, even with a near object largely dominating 90% of the focus spot area. This can be a problem in 3D scenes where there maybe a branch or similar object upon which one wants to focus. All cameras suffer from such behaviors, but an overly large focusing spot is problematic.

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.
