Studying Old Lenses on the Sony A7R II: Voigtlander 90mm f/3.5 APO-Lanthar and Voigtlander 180mm f/4 APO-Lanthar

I’ve added to my review of Voigtlander DSLR lenses* by studying two of the best on the Sony A7R II (as a convenient platform**, since could be done as well on Canon 5DS R). I’m pondering whether to expand that study to the Canon 5DS R (that depends on interest as these are specialty lenses).

The Voigtlander 180mm f/4 APO-Lanthar is one of the best corrected APO lenses around—not even Leica APO lenses approach its level of correction. The Voigtlander 90mm f/3.5 APO-Lanthar also has a high level of color correction. So I thought it would be interesting to study these two and then a few other lenses.

Voigtlander 90mm f/3.5 APO-Lanthar aperture series: Shimano Drive Train (Sony A7R II)

Voigtlander 180mm f/4 APO-Lanthar aperture series: Shimano Drive Train (Sony A7R II)

These are technical studies to assess lens performance, namely sharpness and color correction.

* As per longstanding policy to keep publications cohesive, lens tests regardless of camera body used always go into their native-platform guides, e.g. Nikon DSLR lenses go into DAP. See Which Content is in WHICH PUBLICATION?.

** Dang I love that 12.5X EVF.... when are NiCanon going to get a clue?
