GFX system maximum aperture portrait mirror Huang Fuji GF55mm F1.7 R WR evaluation

It has been more than 7 years since Fuji GFX's medium frame system was released today. Although the GF lens camp has grown year by year, it has always lacked a big light to focus for professional portrait shooting. Fortunately, the release of Fuji GF55mm F1.7 R WR lens last autumn finally filled this gap and became a very important member of the GF lens camp. As the largest fixed focus lens in Fuji GFX system, GF55mm F1.7 R WR has an equivalent full frame focal length of 44mm, which can be regarded as a "beacon" that conforms to the visual angle of the human eye. For professional photographers and enthusiasts, it is the most suitable fixed focal head for hanging on the camera and having extremely high frequency of use in all lenses. In combination with the middle frame sensor and the large aperture of F1.7, whether it is portrait shooting, food still life, cultural street sweeping or landscape creation, They can show excellent picture quality and expressiveness.

A major advantage of Fuji GF55mm F1.7 R WR is that it can make the medium frame fixed focus head with a large aperture more compact and lighter, while maintaining an ultra-high level of optical quality. The lens adopts 10 groups of 14 optical structures, including 2 ED lenses and 2 aspherical lenses, 11 circular diaphragm blades, providing a minimum focusing distance of 50cm; The luxurious and solid materials with the largest aperture of F1.7 also make this GF55mm F1.7 R WR lens provide advanced image resolution and color difference control, and can better create a beautiful shallow depth of field effect.

In today's Fuji GFX, under the trend of more and more compact frame free fuselage design, it is also very delicate Fuji The GF55mm F1.7 R WR mirror head with the GFX100S body looks very harmonious overall, without the feeling of being top heavy. It is suitable as the hanging head of the medium frame camera.

Sharpness:

     Fuji GF55mm F1.7 R WR The lens has 10 groups of 14 pieces, including 1 aspherical lens and 2 ED lenses. In terms of configuration, it should be said that it costs nothing. In combination with short flange distance, large diameter G bayonet, and large aperture, its optical quality performance is very worthy of our expectation. In order to reflect the best performance of the lens, we choose to match the body of about 12 million effective Pixel sensor Fuji GFX100S medium frame no reflection camera. First of all, let's take a look at the performance of the center and edge of the lens under different apertures.

The aperture range of this lens is F1.7-F22. From the above screenshot, in the case of matching the Fuji GFX100S fuselage, the F1.7 full aperture has good central image quality performance, but the edge image quality is slightly fleshy; After the aperture is reduced to F2.8, the sharpness of different positions of the picture also remains relatively high, especially the central picture quality has been significantly improved. After F5.6-F11 aperture, enter the best sharpness range of this lens, the picture is obviously more sharp, and the analytical power of both the center and the edge is very high.

Of course, for a large aperture portrait lens, the key is whether the image quality of the focusing position is clear and solid when the aperture is fully open. From the above live portrait samples and enlarged screenshots, it can be clearly seen that the Fuji GF55mm F1.7 R WR lens is still very sharp in focus. When the F1.7 aperture is fully open, it can clearly show the hair details and skin texture of the characters' eyes, and its analytical power is really impressive. At the same time, the background illusion effect of the lens is also very soft and natural, and the transition between the focus and the background is very smooth.

It is also worth mentioning that Fuji GF55mm F1.7 R WR has the closest focusing distance of 50cm, so it is convenient to take a close-up of a person's face at a relatively close distance when shooting a portrait; Moreover, from the actual shooting experience, this lens can focus very fast even when shooting shallow depth of field photos with F1.7 large aperture. Combined with the camera's eye recognition function, it is very easy to take portraits with clear focus and great sense of space.

Dark corner:

As a large light circle focusing head, Fuji GF55mm F1.7 R WR adjusts the surrounding light loss quite well. Even at the maximum aperture of F1.7, there is only slight dark angle that is not obvious. When it shrinks to F2.8, it is almost difficult to observe the dark angle.

Distortion:

Generally speaking, the standard focal length lens rarely suffers from distortion. From the above live photos, Fuji GF55mm F1.7 R WR lens does not have any obvious distortion, which is almost invisible to the naked eye, so it can be ignored.

Dispersion:

The quality of dispersion and chromatic aberration suppression of lens is also the basic condition to test whether the optical quality of a lens is excellent. In particular, large aperture lenses are prone to dispersion when shooting scenes with high contrast, which is mainly reflected in the blue/green/purple edge phenomenon at the edge of objects in high contrast light. Next, let's test the anti dispersion performance of Fuji GF55mm F1.7 R WR through live shooting.

It can be seen that the Fuji GF55mm F1.7 R WR lens has a very good effect on dispersion suppression. Whether the aperture is wide open or small, there is no obvious dispersion phenomenon such as "purple edge" or "blue green edge" at the light dark junction of the focus position of the picture.

The excellent dispersion suppression at the focus position is expected, but the Fuji GF55mm F1.7 R WR lens also plays an extremely high chromatic aberration control ability outside the focus at the edge of the picture, which is very surprising. It seems that the use of two ED lenses with high refractive index and low dispersion, as well as the optimized lens set design, has really made this lens hair show the strength that a top focusing head should have.

Due to the refraction and reflection of light, the purple edge may be more obvious when shooting objects with reflective surfaces such as glasses at close range. However, as can be seen from the above screenshot of the live shot sample, Fuji GF55mm F1.7 R WR lens has no color difference such as purple edge in the focus and out of the focus of the glass under the large aperture of F1.7, which is really a top performance as a large aperture lens.

Out of focus depth of field:

With the large aperture of F1.7 and the larger size of the medium frame CMOS sensor, Fuji GF55mmF1.7 R WR has a very soft and beautiful out of focus virtual effect at the maximum aperture. The out of focus transition is very natural, truly realizing "creamy opening". The overall picture looks very natural and comfortable, which is a good choice for taking portraits and still life close-up.
