Evaluation of new Sony Quan Huafu lens 24-70mm F2.8II

IT 168 evaluation on April 23rd this year, Sony released the vario-sonnart * 24-70mm F2.8 zassmii. 24-70mm is the most commonly used focal length for general users, covering three classic focal lengths: 24 mm, 35 mm and 50 mm. The large aperture with constant F2.8 is of great significance for background blur and dark light shooting. Sony Quan Huafu lens Vario-Sonnart * 24-70 mm F2.8 Zassmii maintains the same appearance size as the previous generation lens, and its weight is increased by 19g, which enhances the ghost suppression and focusing performance, improves the tracking and focusing speed by about 4 times, and adds dust and splash prevention treatment.

Sony's upgraded Sony Quan Huafu lens Vario-Sonnart * 24-70mm F2.8 Zassmii is designed for professional users. The lens structure with 13 groups 17 lenses includes many aspherical lenses and ED low dispersion lenses. With Zeiss unique T* lens coating technology, it can effectively correct all kinds of aberrations and restrain dispersion. At the same time, in order to have more professional imaging quality and experience, Sony Quan Huafu lens Vario-Sonnart * 24-70 mm F2.8 Zassm II has built-in ultrasonic motor, which can realize smooth and quiet autofocus. With Sony A77II, it can realize various functions of the 4D focusing system and has the ability to detect and track subjects across four dimensions. In addition, the body of Sony Quan Huafu lens Vario-Sonnart * 24-70 mm F2.8 ZASSM II is dust-proof and drip-proof, which can adapt to various shooting environments.

Advantages:

1, solid workmanship, good feel

2, constant F2.8 aperture, excellent blur ability.

3, dustproof and waterproof design, with a certain waterproof ability

Disadvantages:

1 and 974g are heavier.

Purchase suggestion:

At present, in addition to the Sony Quan Huafu vario-Sonnart * 24-70mm F2.8 zassmii lens, there is also a 28-75mm F2.8 SAM lens to choose from, which is the standard zoom lens of Sony A-mount Quan Huafu. As for the sub-factory lens, you can choose Longteng SP 24-70mm F2.8 Di USD or the 24-70mm F2.8 IF EX DG HSM lens released by Sigma for a long time. Generally speaking, this Sony Quan Huafu Vario-Sonnart * 24-70mm f 2.8 Zassmii lens has more professional imaging quality in the standard zoom lens with constant F2.8 aperture. Nevertheless, we still need to consider its own weight of 974g and the price close to 13000 yuan. Click to learn more. If you are a professional photographer who uses Sony A bayonet camera and pursues professional imaging quality and experience, then this is the best choice. If you are an ordinary photographer, then I suggest you consider a more cost-effective sub-factory lens.

The appearance is the same as that of the previous generation, and dust and splash prevention treatment are added:

▲ The appearance is consistent with the previous generation.

▲ T coating on the front of the lens

▲ T coating on the back of lens

The lens marked with T* is a Zeiss T coated lens. The function of this coating is to inhibit the specular reflection of the lens, make the light pass through the lens as much as possible, increase the transmittance, reduce glare and ghost, and improve the imaging quality.

▲ Focus mode switch key

Sony's 24-70mm F2.8 II lens is equipped with a focus mode lever, so users can choose between auto focus and manual focus. In addition, there is a focus stop button. After the photographer successfully focuses by pressing the shutter for half a time, he can press this button to release the shutter release button, and the autofocus system will not start until the focus stop button is released.

▲ The mirror body is provided with a focusing window.

The lens body is provided with a focusing window, which is convenient for focusing judgment when focusing accurately manually.

▲ The front of the lens is engraved with the lens model.

▲ Metal bayonet is equipped with drip-proof, splash-proof and orange waterproof ring.

Sony's 24-70mm F2.8 II lens adopts a metal bayonet, and an orange rubber waterproof ring with anti-drip and anti-splash structure is arranged around the bayonet to play a waterproof role. The coating color tends to be green and light red.

▲ Lotus-shaped metal hood

Wide-angle resolution test:

Next, we use Sony A99 fuselage with Sony Quan Huafu lens Vario-Sonnart * 24-70mm F2.8 ZASSM II lens to take samples of each aperture at the 24mm end, and cut off the central and edge parts of the picture to enlarge 100% for comparison.

▲ Sony Quan Huafu lens vario-sonnart * 24-70mm2.8 zassmii 24mm end resolution test.

The aperture of the lens at the 24mm end is relatively large, and the resolution of F4 is reduced by one step, and the sharpness is obviously improved, which can be kept to F 1 1. On the other hand, the edge image quality is fleshy, and it is improved when F8 reaches F 1 1. After F 1 1, the imaging quality of the center and the edge decreases, but the center imaging is still better than the edge. Therefore, it can be concluded that the imaging of the lens center has a high level at all aperture positions, while the edge is weaker than the center.

Long focal length resolution test:

Next, we use Sony A99 fuselage with Sony Quan Huafu lens Vario-Sonnart * 24-70mm F2.8 Zassmii lens, take samples of each aperture at the 70mm end, and cut off the central and edge parts of the picture to enlarge 100% for comparison.

▲ Sony Quan Huafu lens vario-sonnart * 24-70mm2.8 zassmii resolution test 70mm end.

When the aperture at the focal end of the lens is fully opened by 70mm, the image quality at the center is sharp, F4-F 1 1, and the image quality at the edge is sharp from F2.8 to F4, from F5.6 to F 1 1, and f1at the back center and edge. The conclusion is the same as that of the 24-end lens. The imaging of the lens center has high imaging quality at all aperture positions, while the edge is weaker than the center.

Dark angle test:

Considering the actual use of ordinary users, we started internal correction in the test.

24 mm end dark angle test:

70mm end dark angle test:

At the end of 24mm, the dark angle of Sony Quan Huafu vario-Sonnart * 24-70mm f 2.8 zassmii lens is obvious. At the end of 70 mm, the dark angle basically disappears after the double aperture is reduced to F5.6, even at the aperture of F2.8, there is only a slight dark angle, and the dark angle basically disappears after F4. On the whole, this lens controls the dark corners very well, which is hard to avoid at the wide-angle end of the lens. In fact, there is no need to worry about the influence of dark angle on the final imaging, and dark angle also has the function of highlighting the main body.

4D focus test:

Sony Quan Huafu vario-Sonnart * 24-70mm F2.8 zassmii is equipped with SSM ultrasonic focusing drive system. With A77II fuselage and 4D focusing system, it can achieve better focusing speed and accuracy, and give full play to 4D focusing performance. Let's take a look at its excellent focusing effect through video.

When Dabai began to shake in the video, A77II focused on Dabai, perfectly capturing its trajectory. When Dabai was moved out of the picture and then moved back, the focus was still locked on Dabai. In the actual experience, the effect of 4D focusing is still very good.

Glare test:

▲ Slight glare appears at the 24mm end when the aperture is fully opened.

When the aperture is fully opened, there is slight glare at the 24mm end, which shows that Zeiss's unique T* lens coating technology can effectively control glare, so there is no need to worry about daily use.

Purple edge test:

▲24mm purple edge test

▲70mm purple edge test

Through the above tests, we can see that. At the wide-angle end of 24mm, purple edge appears in Gao Fancha area when the aperture is fully opened, and disappears after the aperture is reduced by one step. However, the overall control of the purple edge by the 70mm telephoto end is excellent and difficult to find. On the whole, thanks to the lens structure of multiple aspheric lenses and ED low dispersion lenses, the purple edge control is excellent.
