More focus shift: 35mm, 100mm, 135mm, more

I’ve now completed my first pass at focus shift (see the free introductory article Introduction to Focus Shift). DAP now includes several additional lenses in the 50mm range, as well as ~35mm, ~100mm and 135mm lenses. Canon, Nikon, Voigtlander, Zeiss and Sony Alpha now have coverage.

The “10” mark should be sharp!

The ~50mm focal length is most problematic in general. Why this should be is unclear. Read the full report in DAP for details.

Focus accuracy and diopter adjustment are additional issues that are independent of focus shift.
