This lens follows the compact, large-aperture concept common to all Miyazaki Optics lenses.
The lens model and focal length are slightly different, but the weight and lens diameter are about 2/3 of the CANON 50mm/F1.2.
In order to make the lens compact, there is almost no gap between the front element and the lens barrel.
I like the good image quality obtained from the simple 4-elements-in-4-group lens construction and the unique blurring at the edges.

F1.2(Max aperture)


The lens I own has a moderately heavy aperture and the aperture does not change unintentionally when focusing, which is a problem with some Ms-optics lenses.
This lens would be one of the historical series, but is not mentioned in the description.

Lens specification
Large aperture standard lens, lens format is Ernostar type.
The lens features very high resolution in the center, but peripheral areas show little improvement even when the aperture is closed.
The focal length of 55mm was chosen because Miyazaki said that he wanted to create a lens with a focal length close to that of a large aperture standard lens (50mm) in the Ernostar type, and that 55mm was adopted as a compromise to reduce that negative in the Ernostar type, which tends to have poor peripheral areas.
As stated in the manual, this lens is designed for portraits with a very good center.
Black, silver, and gold were identified as color variations.
