1．Overview
The H-Pez 57mm and Vario-Pez 57mm are the third installment in the MS-Optics (Miyazaki Optical) history series, and are lenses that pay homage to the Petzval format.
The lens configuration of 4 elements in 4 groups is the same as the original Petzval, but Petzval-type lenses are long-focus lenses and are not suitable for Leica M mounts as is. Therefore, in order to make the focal length more generally usable, Miyazaki reconsidered the lens configuration with his own interpretation and adopted a focal length of 57mm.
The minimum shooting distance is 0.7m, and it is linked to the rangefinder of Leica M cameras up to 0.8m.
2．Usage
This lens has a subtle focal length and it is difficult to find a clear motivation to use it, so it is used very little. Since I have the successor, Vario Petz, I rarely use it.
The subtle focal length of this lens does not cause any problems when used with the EVF of a mirrorless camera, but when used with an M-type Leica rangefinder, there is no problem if you keep in mind that the image will be captured slightly inside the 50mm frame.
When I asked designer Miyazaki about the focal length of 57mm, he said that with this lens configuration, it would be difficult to maintain the lens performance that the designers wanted by increasing the focal length from the current focal length, so 57mm was the limit. In addition, we received feedback from users of this lens that “When I used it, it was a more normal lens than I imagined,” so it will be released as an additional Vario Petz, which allows photographers to adjust the image more flexibly.
3．Vario version
The Vario-Pez has the same lens structure and shooting functions as the H-Pez, but a movement index is provided on the rear lens, and by moving the rear lens, it is possible to control spherical aberration (SA).
This mechanism is the same as the function implemented in the APORIS 135mm released in 2017, which has a large lens barrel size. The Vario-Pez incorporates this into a smaller standard focal length lens, and was completed in 2019 with the Vario-Pez. Although it is an unofficial function, there are other Ms-optics lenses that allow you to adjust the infinity position and control aberration by moving the rear lens group.
It is recommended to use it with a mirrorless camera because there are abnormalities in the linkage with the rangefinder camera’s rangefinder when it is not in the center position. The specific effects of changing the position are described in detail in the Vario-Pez instruction manual and in my book “Ms-optics Lens 2: The World of Miyazaki Lenses 2”.
