SONNETAR 73mm F1.5 photo example (with LEICA M-P / LEICA M10)

Among Miyazaki’s lenses, this lens and the APORIS 135mm are the only lenses that exceed a focal length of 60mm.
Mr. Miyazaki says that his choice of 73mm focal length was made with the “Leica Hector 73mm” in mind, and although I would like to see him challenge the 75mm Summilux, I think it is a choice that is typical of Mr. Miyazaki, who loves old lenses.
This lens is very compact, with a barrel about the same size as a large 50mm standard lens, and it fits in a camera bag better than Voigtlander and Leica 75mm class lenses, so it is very useful to have it.
The exterior of the lens is well finished, with a design similar to that of the ELNOMAXIM, but the direction of rotation of the aperture is the opposite of that of the ELNOMAXIM, which is curious.
The rangefinder is a bit difficult to use for focusing when the aperture is wide open, so using the EVF is probably the safest option when considering focusing accuracy.
Used with HASSELBLAD X2D, it covers about 40.5 x27mm (when trimmed 3:2) out of 44 x33mm.

Lens specification
The first bright medium telephoto lens with a focal length of 73mm from MS-Optics (Miyazaki Kogaku).
The lens boasts an astonishingly compact size for a lens with a focal length of 73mm / F1.5, thanks to an ingenious method of mounting the front element, which is the largest in diameter.
