Review

H PETZ 57mm is the third installment of MS-Optics’ (Miyazaki Optical) historical series and is a lens that pays homage to the Petzval lens.
The four elements in four groups are the same as the original Petzval, but since Petzval type lenses are long focal length lenses and it is difficult to shorten the focal length, the lens configuration was revised.
The 35mm film size is 57mm, which has a slightly longer focal length than the standard 50mm.

This lens has a delicate focal length and a low usage rate because it is difficult to have a clear motivation to use it. Since he has the successor Vario Petz, he rarely appears.

Regarding this lens, I heard from Mr. Miyazaki that If the focal length is shortened any further, the performance cannot be guaranteed.'' In addition, after hearing from users of this lens thatWhen I used it, it was just an ordinary lens,” the Vario Petz was developed to allow more flexible adjustment of aberrations.

The delicate focal length of this lens is not a problem when using it with an EVF, but when using it with a Leica rangefinder, be aware that it will capture a little bit inside the 50mm frame.
