The new benchmark of domestic Yashen Mingjiang M50mm f/0.95 trial experience
This article comes from Jiayou Online
F0.95 is indeed a very challenging aperture value. The news of Mingjiang 50/0.95 research and development actually started last year. The most noteworthy thing is that the raw materials and grinding of the large-diameter aspheric lens are all done in China. Such operations involve certain risks. I remember Mr. Li, who had interviewed Mingjiang about this issue, his answer was this. If this lens was assembled with all foreign parts, it would lose his meaning.
The 67-caliber TTArtisan M50mm F0.95 still uses Mingjiang Consistent packaging style, white cardboard box plus an inner packaging similar to the structure of a watch box. There is indeed a sense of luxury when opened. The outline of the lens is outlined on the cardboard box.
Open the front of the inner package box that wraps the lens inside the cardboard box The lens specifications of this lens and the optical structure of this lens are printed.
In addition to the lens itself, different cameras are considered in the package The flange distance difference is equipped with a focusing screwdriver and a focusing jam. But the lens in my hand does not have a focus problem, and it is ready to use.
Its implementation now uses LCD screens in addition to Leica macula users Or there are more and more users of EVF viewfinder with peak focus. Changes in photography habits have made the past focus estimation shooting methods become niche, and even blind shooting of many people is done by using mobile phone viewfinder. However, for Mingjiang itself, the consideration of more than one is necessary to meet more users with different needs.
M50mm F0.95 uses 11 elements and 8 groups of optics The structure, and this includes a previously mentioned large-size aspheric lens which is entirely made from domestic materials and ground domestically. This is the biggest development difficulty of this lens, and of course it is also the key to this lens. In addition, there are 8 high-refractive-index lenses. These lenses ensure the good sharpness of this lens when the aperture is fully opened. The later tests have indeed proved the sharpness of this lens. The sharp imaging under large aperture is indeed the advantage of this lens.
The diameter of M50mm F0.95 is 67mm compared to the original factory 60mm is a larger circle, with a length of 74mm and a width of 72mm. The volume is similar to the value of the original Leica lens. It weighs 673g, and it does feel like a small grenade in your hand. From the appearance, the lens is indeed quite similar to the original lens. It can be regarded as a tribute to the original factory.
Compared with the original lens, this lens has a The advantage that must be mentioned is the focusing distance of this lens. The closest focusing distance of this lens is 0.7m, while the closest focusing distance of the original 50/0.95 is 1m. The 30cm gap is really a key point that is difficult to ignore for many Leica users.
This lens is currently only available in black, but it is quite interesting This lens has a brass design deliberately used on the mount. This lens, which should have been the main tone and low-key, added a sense of boredom. I think this should be the same as the deliberate use of the yellow font at the aperture value of F0.95, which is a manifestation of the designer’s deliberate bright show.
In terms of workmanship, the previous lenses of Mingjiang It has embodied the texture he pursued, and this lens also gives people such a feeling, the aperture ring has a clear transition, and the damping of the focus ring is also very appropriate, and it is also quite smooth when adjusting the focus.
For the lens, the sharpness drop at a large aperture would be A relatively common phenomenon. But this lens is surprising at this point. Even at a large aperture, considerable sharpness and resolution are guaranteed. There will be relatively obvious feelings in the actual shooting and sample shooting.

In terms of vignetting, this lens has relatively obvious vignetting under the full aperture, and the vignetting is gradually improved as the aperture shrinks step by step. This lens does not perform very well in distortion control, and there is relatively obvious distortion.
The maximum aperture of this lens is F0.95, and its blurring effect is the reason why many people pursue this lens. From the actual test, the blur effect of the lens is relatively good. And it can also show a satisfactory starburst effect under the smallest aperture. In addition to portrait shooting, it is also a relatively good choice as a night shot lens.
TTArtisan M50mm F0.95 is currently less than 5,000 yuan. This price naturally does not need to compare with the original Leica lens of 100,000 yuan after all. However, the actual experience this lens gives users is completely value for money. The sharpness and blur effect are actually very satisfying. And its closest focusing distance of 0.7m gives users the possibility of shooting at close range. In fact, from my personal understanding, this lens is not only for Leica users, it is more for micro-single users, especially Sony, which can achieve Leica mount lens autofocus under the Tiangong adapter ring. user. For such users, this lens is undoubtedly a great value lens that combines portrait and humanity. And as a domestic lens, the emphasis on high-precision craftsmanship is also a commendable highlight.
