H-PETZ 57mm F2 Photo example (Photographed by Leica M-P Typ240)
Impression
Since Petzval-type lenses are long focal length lenses and it is difficult to widen the angle of view, 57mm was chosen as a compromise between image quality and the standard focal range for 35mm film size.
The subtle focal length of this lens is not considered a problem when used with an EVF, but when used with a Leica rangefinder, the photographer should be aware that the image will be slightly inside the 50mm frame.
Lens specification
The third lens in MS-Optics’ (Miyazaki Kogaku) historical series, the Petzval Homage lens.
Mr. Miyazaki told me, “It turned out to be a more ordinary lens than I expected.” and based on this reflection, Vario-Petz was developed.
