IT168? Review The A7 series of full-frame mirrorless cameras launched by Sony in the past two years have been a great success in the field of mirrorless cameras. Professional photography is no longer the exclusive domain of high-end digital SLR cameras.

In order to further enhance its professionalism, Sony has successively launched the Distagon T* FE 35mm F1.4 ZA, FE 24-70mm F2.8 GM, FE 70-200mm F2.8 GM OSS and FE 85mm F1.4 GM lenses.

Not only that, not long ago, Sony released the Sony Planar T* FE 50mm F1.4 ZA lens.

With the emergence of this lens, the Sony F1.4 large-aperture fixed-focus lens group has achieved coverage of the three commonly used focal lengths of 35mm, 50mm and 85mm. I believe it will also become a strong reason for professional photographers to choose Sony.

"Main parameters: Lens structure: 12 elements in 9 groups (2 aspherical lenses, 1 ED lens, T* coating) Number of aperture blades: 11 closest focusing distance: 0.45m Filter size: 72mm Maximum magnification: 0.15x lens

Weight: 778g Lens size: 84×108mm" Advantages: 1. 11 circular aperture blade design, soft and natural out-of-focus 2. The lens has an infinite aperture lever, which is optimized for both still photos and videos, making it convenient for video shooting needs

User use 3. Sturdy metal lens barrel, with a waterproof and moisture-proof sealing structure, enabling all-weather shooting 4. Excellent image quality, available at full aperture "Disadvantages: 1. Slightly larger size and weight 2. Average focusing speed" Buying advice: Sony Planar

The T* FE 50mm F1.4 ZA lens is a lens suitable for professional photographers and high-end photography enthusiasts.

Paired with the high-pixel full-frame mirrorless body A7RII, you can achieve excellent image quality performance.

It subverts the previous rule that standard fixed-focus lenses with double Gaussian structures need to shrink the aperture in order to obtain high resolution.

At the same time, it goes without saying that the advantages brought by the 1.4 aperture are not only better blur effects, but also the ability to increase shutter speed in some environments.

Only when the aperture is fully opened will slight vignetting and purple fringing appear.

Although the focusing speed is not amazingly fast, if this lens is not used to shoot sports subjects, it will have no problem at all with this focusing speed.

Overall, this is a very professional lens with good quality, so much so that it is hard for me to imagine how far it will go to surpass this lens if there is a Sony FE 50mm F1.4 GM in the future.

Therefore, if you are a professional photographer or a high-end photography enthusiast, you are those who have very high requirements for image quality.

As long as you don't care about the price, just buy it.

If you are an ordinary enthusiast or buy the A7 series just for the sake of portability, it is not too burdensome to travel.

Then you will be more concerned about the price, size and weight of the lens. Obviously the Sony Sonnar T* FE 55mm F1.8 ZA" click to view details is more suitable for you. The difference between the two lenses is actually very small, but the Sonnar T* FE 55mm F1.

8 ZA has obvious size and price advantages. In short, no matter which one you choose, you will not be disappointed. "1. Large size and solid workmanship: Although this lens is unboxed by the new lens king Sony FE 50mm F1.4 ZA in the photo album.

It doesn't feel as "huge" as the GM lens, but it still feels substantial for a lens.

But don't be intimidated by its size, because it is indeed very "material".

" 2. Sharp and impressive details. The well-known "little blue label" Zeiss, with its profound accumulation in optical design and unique secrets in lens processing and coating, has always been in the leading position in image quality among products of the same specification at the same time.

Especially for the Otus series, products do not compromise on autofocus, size, weight, and cost. What they pursue is ultimate image quality. However, recent test results from Lensrental show that the center image quality of the Sony FE 50mm F1.4 ZA lens is even better.

Better than the Otus 55, and the edge performance is comparable to the Otus 55.
