IT168? Evaluation
The A7 series of Quan Huafu micro-cameras launched by Sony in recent two years have achieved great success in the field of micro-cameras.
Professional shooting is no longer the patent of high-end digital SLR cameras. In order to further enhance its professionalism, Sony has successively introduced
Distagon T* FE 35mm F1.4 ZA, FE 24-7mm F2.8 GM, FE 7-2mm F2.8 GM OSS and FE 85mm F1.4 GM lenses. Not only that, not long ago, Sony released the
Sony Planar T* FE 5mm F1.4 ZA lens. With the appearance of this lens, Sony
F1.4 large aperture fixed-focus lens group has achieved the coverage of three commonly used focal lengths of 35mm, 5mm and 85mm, which is believed to be a powerful reason for professional photographers to choose Sony.
"main parameters:
lens structure: 9 groups with 12 lenses (2 aspherical lenses, 1 ED lens and T* coating)
number of diaphragm blades: 11
closest focusing distance: .45m
filter size: 72mm
maximum magnification: .15x
. 11 circular aperture blades are designed, Jiao Wai is soft and natural
2. The lens is equipped with an endless aperture lever, and it is also optimized for still photos and videos, which is convenient for users with video shooting needs
3. The solid metal lens barrel has a drip-proof and moisture-proof sealing structure to achieve all-weather shooting
4. The picture quality is excellent. Disadvantages of
"full aperture:
1. Slightly large volume and weight
2. Average focusing speed
" Buying suggestion:
Sony Planar T* FE 5mm F1.4 ZA lens is a lens suitable for professional photographers and high-end photographers. Excellent picture quality can be achieved with the high-pixel Quan Huafu A7RII. It subverts the law that the standard fixed-focus lens with double Gaussian structure needs to shrink the aperture in order to obtain high resolution. At the same time, it is needless to say that the advantages brought by 1.4 aperture not only provide better blur effect, but also improve shutter speed in some environments. Only when the aperture is fully open will there be slight dark corners and purple edges. Although the focusing speed is not surprising, if this lens is not used to shoot sports subjects, there is no problem at this focusing speed. Generally speaking, this is a very professional lens with good quality, so it's hard for me to imagine how far I can surpass this lens if there is Sony FE 5mm F1.4 GM in the future.
So if you are
a professional photographer and a high-end photography enthusiast, you are the ones who have high requirements for image quality.
as long as you don't care about the price, buy it in buy buy. If you are an ordinary lover or buy A7 series just for the sake of lightness, the burden of traveling is not too great. Then you will pay more attention to the price, volume and weight of the lens. Obviously, Sony Sonnar T* FE 55mm F1.8 ZA
"
Click to view the details, which is more suitable for you. The gap between the two lenses is actually very small, but Sonnar T* FE 55mm F1.8 ZA has obvious advantages in size and price. In short, no matter which one will not let you down.
" 1. Huge volume and solid workmanship:
The new mirror of the atlas header, Sony FE 5mm F1.4 ZA, is unpacked
Although this lens will not feel very "huge" like GM lens, it is still full of weight as a header. But don't be scared by its size, because it is really "material".
" 2, the details are sharp and impressive
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 the products of the same period and specifications. Especially the Otus series, the products are not compromised by autofocus, volume and weight, cost and price, and the pursuit is the ultimate image quality.
However, the test results given by Lensrental recently show that the center image quality of Sony FE 5mm F1.4 ZA lens is even better than that of Otus 55, while the performance of the edge part is equivalent to that of Otus 55. So, does this lens perform first-class as they say, and become the best one in the 5mm lens?

"
Sony FE 5mm F1.4 ZA
has two aspherical lenses (including a high-precision "AA" advanced aspherical lens) and an ED (low-dispersion) lens, which reduces spherical aberration and dispersion to a lower level, not only providing high-resolution and high-contrast performance from the center to the edge of the picture, but also enabling the image quality with the nearest focus distance to infinity.
We use Sony A7RII fuselage with
Sony
FE 5mm F1.4 ZA
lens to take samples, and take 1% enlarged screenshots of the center and edge of the picture for comparison:
▲
Resolution test
From the 1% enlarged screenshots of the real samples, Sony
Fe When the aperture shrinks to F2.8, the resolution of both the center and the edge is quite sharp. There is a slight decline from F11, but the sharpness is very good. Generally speaking, Sony
FE 5mm F1.4 ZA lens shows very sharp picture details in the whole process, which can fully meet the daily shooting needs even if the aperture is fully open. Without
Otus 55mm in hand, it's hard to say which of the two lenses has better image quality, but the performance of Sony
FE 5mm F1.4 ZA lens will not disappoint you.
▲ With A7RII, the real shooting effect is staggering
"
3. The overall control of the dark angle is good, and the aperture is fully open and slightly visible
From the actual test, the dark angle of this lens is obvious under the large aperture from F1.4 to F2.8, and it performs well between F4 and F16. When the aperture of a large aperture lens is fully open, it is inevitable that there will be dark corners. Generally, with the decrease of aperture, the dark corners will gradually decrease and disappear. Dark corners can be removed later, and it also has the effect of highlighting the central figure in the picture. So there is no need to worry too much.
4. Slight purple edge phenomenon?
excellent anti-glare and ghost performance
▲
purple edge test
Sony FE 5mm F1.4 ZA
has two aspheric lenses (including a high-precision "AA" advanced aspheric lens) and an ED (low dispersion) lens
, which can effectively correct the dispersion under large aperture. However, from the screenshot above, When the aperture shrinks to F2.8, the purple edge basically disappears. After that, the purple edge was well suppressed. On the whole, the purple edge control of the lens is good, users can shoot at large aperture, and the purple edge can be removed by post-processing or the aperture can be reduced.
In addition, the anti-glare and ghost performance of this lens is also very good. There is no obvious glare when shooting with large aperture backlight in sunny outdoor. As there is no hood during the test, I believe that when you use this lens, you will not be affected by glare after adding the hood.
"
5. Blurring is obviously slight
Aperture erosion occurs
Sony
FE 5mm F1.4 ZA
lens
uses an 11-blade circular aperture,
ensuring a soft and natural Jiao Wai blur effect
. So what is the actual performance of this lens?
from the outdoor proofs taken in the daytime, the blur effect of Sony
FE 5mm F1.4 ZA lens is very obvious under the full aperture, and the blur effect of Jiao Wai is soft and natural.
According to the indoor proofs, although there is no "onion ring" phenomenon in the background spot, there is still
aperture erosion when shooting with a large aperture. Although
aperture erosion is an unavoidable phenomenon in any lens, it has a certain influence on the photos to some extent. You can make up for it by
narrowing the aperture.
