90/2 APO vs 100/2.8 APO-Macro: Barcroft Blue Building (M240)
Shot on the 24-megapixel Leica M Typ 240.
The goal is to get some idea of the relative merit of the 90/2 APO ASPH versus the 100/2.8 APO macro for distance shooting.
An attempt was made here to match reproduction size of the 90mm and 100mm focal lengths by moving back, so as to yield a basis for comparing the relative optical performance. Regrettably, camera leveling was off (the M240 was not very helpful here), but working with a small tripod is always problematic in matching such things (hey, at 13,000' cycling up, the big heavy one isn’t going along!). However, the value remains in the comparison nonetheless.

- 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.
