First of all, thanks to the appearance of @-Tokisaki_Kurumi-, thanks to the @Sony Store, and @Starbucks China's very good looking shops. The photos in the text were all taken by myself. Some of the photos were reproduced and they were not processed. (In order to highlight 1.4, it is good to use 1.4 in shooting. Please do not study, please do not learn, especially back light.)
The 50mm focal length lens, also called the header, is a relatively classic focal length.
The title of the header is derived from the father of Leica - Oscar Barnack created the film size of 36X24MM. For the 135 camera, due to the distance between the lens mount and the imaging plane and the size of the film image field, the angle of view and the imaging perspective of the lens with a viewing angle between 57° and 40° are closer to the human eye. At the same time, the focal length between 40mm and 60mm is equivalent to the diagonal length of the 35mm film, so this focal length lens is called a standard lens and can reproduce the most natural visual effects with a close to real liveness.
The header has always been a place where manufacturers have shown their talents. Forenda, Zeiss, Leica and others have contributed classic shots one after another. The rising Sony micro single can certainly not miss this classic focal length and has released two lenses of 55 F1.8 and 50 F1.8. However, many movie friends are looking forward to the appearance of the F1.4 lens. After the release of the GM master lens, the rumors about the 50 F1.4 continue to prove that the film's friends are looking forward to this lens.
Finally, in July 2016, Sony E bayonet 50mmF1.4 lens to meet with you.
Planar T FE 50mm F1.4 ZA (hereinafter referred to as 50za) is a standard fixed-focus lens designed for professional photographers and high-end photographers seeking outstanding resolution and contrast. The lens adopts 9 groups of 12 double-Gaussian structures, built-in two aspherical lenses and one ED (low dispersion) lens. At the same time, Zeiss T coating is used, making the anti-glare ability even better, in the case of backlighting or side backlighting. Shooting can also obtain high-definition, high-contrast images, effectively reducing the appearance of ghosts.
The F1.4's large aperture brings the advantage of light into the shot. 11 round aperture design, get a more soft blur effect. Focused on the use of SSM ring ultrasonic motor, let the focus more quiet and rapid. In addition, the electrodeless aperture design enhances the ability of video shooting.
Judging from the parameters, the 50za is heavier, similar to the 85GM, and the weights of the two are similar when installed. However, the shooting feel is very suitable. Even if it is taken for a long time, it does not feel uncomfortable.
It is not difficult to see that the lens is very solid workmanship, using a dust-proof and splash-proof design, and can be competent for shooting work in more occasions.
Like the 35 1.4, the aperture ring is set, and the aperture adjustment is provided to enhance the ability of video shooting.
The A7 and 50za are used in the video. The center point focus is used to perform far and near transform focusing and multiple focusing on the same object.
50za uses SSM ring ultrasonic motor, compared with 50 F1.8, 55 F1.8, more accurate and faster focusing. In the far and near transformations, it is also possible to focus quickly, and it will be faster to coordinate with A7R2 and other machines.

The sharpness of the coke. We magnify 100% of the focus position, and the lines of the fingers are clearly visible. The shallow depth of field of 1.4 is also very obvious.
In the case of a hyperfocal distance, a 1.4-inch aperture is still used for shooting, and the sharpness is excellent. The details of the human face are clearly visible. If you wish, you can count your hair.
Circular aperture
The 50za uses 11 circular aperture designs to achieve a softer blur effect. The definition of a circular aperture is that after the maximum aperture shrinks by 1-2 stops, the aperture still remains circular. On the one hand, the difference between the actual aperture and the nominal aperture is reduced. On the other hand, the out-of-focus imaging is also improved.
The above figures are the focal spot shapes of F1.4 and F2.5, respectively. Both figures have obvious circular spots. In the case of F2.5, the shape of the spot on the edge is more rounded.
The second map also shows the transition from focus to focus. From spectacles to tables to glass farther away, the blur transition is excellent, and the out-of-focus imaging is very soft.
Large aperture lens in the case of strong light, the basic will appear purple edge, green edge and other issues, this does not mean that the quality of the lens is not good, can only say that the optical limit it. 50za did not get rid of this shackles.
The sun shines on the text on the clothes outside the window, and there is a clear green edge. This is not a problem. It can be easily eliminated in the later period. However, in some circumstances, yellow edges may appear.
In the case of F1.4, the vignetting performance is still quite obvious. Contraction to the F4 almost disappeared. In terms of distortion, some pictures in the later adjustments used distortion adjustments of -3. It can be said that the control is still good.
to sum upThe 50mm focal length lens is the lens closest to nature and close to reality. It is naturally a lens that professional photographers cannot miss. The appearance of 50za also made up for the lack of 50mm focal length for Sony Micro. The 50za continues the high-resolution, high-contrast imaging features of the Zeiss lens, supplemented by fast and accurate focusing, infinite aperture adjustment, and the ability to shoot in a variety of scenes. It is indeed another masterpiece of the Sony Micro Single lens.
