SONNETAR 50mm F1.3 Photo example (with Leica M-P)
I tried the new 50mm/F1.3. It has the same characteristics as the previous lens, which is soft at maximum aperture and becomes high-resolution when stopped down, but the sharpness when stopped down is even better. The lens construction is the same, but the design has been brushed up. I would like to compare the results in the near future under the same conditions.
In terms of shooting functions, we are also pleased that the minimum focusing distance has been shortened from 1m to 0.7m.
The aperture is the familiar clickless aperture of Ms-optics, and while I have no complaints about the aperture position, the one I own has an overly smooth aperture feel and sometimes changes unnecessarily. A little more weight would be better.
Here are the old and new 50mm / F1.3 side by side.
The new model on the right uses a special lens barrel and has a refined appearance. The old model on the left was released in 2009 (13 years ago). The lens and mount can be separated, and the mount part is provided in two types, L39 and S-mount, and is made to be interchangeable. The ready-made MS-51.6 is used.
The old 50mm / F1.3 will be introduced again in a separate article.
The first lens released by Ms-optics (Miyazaki Kogaku), MS-mode-S, is a Sonar-type 50mm lens redesigned with current technology.
It has a Coma correction function on the rear lens element. The standard position of the lens is at 3m, and at this position, the lens can be linked to the rangefinder of Leica rangefinders. (Indicators are set at 0.75, 1, 1.5, 3, and ∞.)
The company plans to release the product in silver and black, and color variations are currently unknown.
