With the development of film and television technology, the picture ratios we see daily are also gradually changing, from the earliest 4:3, to 16:9, and then to 21: 9. From the beginning of the movie, we can see that the frame ratio has become wider and wider. However, it is not easy to make a wide screen picture. You must know that the mainstream CMOS size of the camera we use daily is still 3:2 or 4:3. If you want to shoot 16:9 pictures, you need to cut the upper and lower parts. If you want to take a wider picture, the entire CMOS area will be smaller. Therefore, the wide-screen anamorphic lens came into being: The 50mm f1.8 wide-screen anamorphic lens we tried today is through a special optical design. In the early shooting, the wide-screen picture information fills the entire CMOS. Later, the screen ratio was adjusted to obtain a 2.4:1 widescreen effect. Compared with ordinary lenses that require large-scale cropping, wide-screen anamorphic lenses can maximize the use of CMOS sensor area to obtain better picture quality. Let’s take a look at such an interesting product.
Design and workmanship comments

Like this kind of big backlight scene, 1. In fact, it tests the anti-dispersion ability of the lens, but from the actual performance, this lens has withstood the test, and the purple fringing is not obvious.
In addition, this lens has a large aperture of F1.8, You can easily achieve the charming bokeh effect. Because of its deformation characteristics, the out-of-focus light spot presents a slender oval shape, which makes it easier to highlight the subject and create a movie texture.
Take a closer look at the out-of-focus performance of this lens, no Onion rings, bilinearity and obvious dispersion can be regarded as very pure and high quality. This kind of performance, even in a continuous picture like video, the audience will not feel discomfort.
