Leica BEOON Rodagon APO versus Componon-S

Head-to-head the APO Rodagon bests the Componon-S. At least the two versions I tested, so sample variations could be in play. I may have a great Rodagon and and so-so Componon-S (SN 14440752). This version is not the copy with the green circle. See the image of the lens below. My Rodagon is not the later “N” version.

One other factor is actual focal length. The Rodagon is perfect to fill the frame of a B&W negative. The Componon must be a tad longer than 50mm as I cannot capture the entire frame with the Componon. Comparing the Bebe images below show the image loss with the Componon.

The first image below is from a Kodachrome 64 image showing the lower-left corner at 100%. Click the B&W images for a larger downloadable version. The extreme corners are better with the Rodagon.
