But if you want to take better quality videos or photos, a good camera with a good lens is still the first choice of many photographers, and many video production teams still choose high-end equipment in the selection of equipment. The best proof of this is the use of photographic equipment.
The SEL20F18G lens, the latest product of the E-mount G master lens launched by Sony in February this year, has a 20mm ultra-wide angle and F1.8 large aperture, which is the widest in the current E-mount series. One of the fixed focus lens. If photography has high requirements, then this lens is an ideal choice, and the lightweight body is also very friendly to photographers carrying all kinds of equipment.
Appearance——Small and light, with rich functions
The Sony SEL20F18G lens has a concise appearance. Due to the use of two advanced aspheric lenses and an improved mechanical structure, the size of the entire lens is controlled at 75.4mm*92.4mm. The lens is very small and can be carried in a special storage bag. Then you can put it in our bag.
The weight of the entire lens is controlled within 400g, which can be said to be quite Lightweight, even girls can easily carry it with them. It is not difficult to see that Sony has a deep technical background in the design and manufacturing of the lens field.
The lens itself has rich functions, focusing ring, focusing button, aperture ring , There are many AF/MF focus switch levers, which is convenient for users to adjust directly through the lens when shooting, without having to go back to the main screen menu for settings, which provides a lot of convenience. At the same time, the focus hold button can forcibly lock the focus point. This function is especially useful when shooting a moving subject, even if the subject moves, it can be clearly frozen.
There is a CLICK with a fixed aperture on the other side of the lens ON/OFF switch lever.
For a lens product, the most important thing is its optical structure. Sony used a sincere pile of materials in the SEL20F18G lens. The configuration of 14 elements in 12 groups is quite attentive. It also includes two advanced aspherical lenses and three non-dispersive lenses.
The role of aspherical advanced lens is to ease the appearance of wide-angle lenses. The phenomena of astigmatism and curvature of field make the pictures more natural. The low-dispersion lens can optimize the dispersion phenomenon in the photo, reduce the phenomenon of glare, especially when shooting against the light to make the film more excellent and natural. In addition, it is compatible with 67mm filter to filter out the messy light for better shooting.
In addition, the lens is easily touched and contaminated by fingers during use For dust floating in the air, Sony added a fluorine coating to the lens of the lens to prevent dirt and clean. In order to allow the lens to be used normally in complex outdoor environments, the interior of the lens is also designed to be moisture and dustproof. This can be more handy for outdoor use.

The camera can be combined with a stabilizer or a Bluetooth handle to create a convenient and professional image production platform. For many junior photographers, it can also produce stable and beautiful images.
Picture quality test-only clear and beautiful shots
The lens test is still based on actual performance. During the short vacation, I took SEL20F18G and a7R out for actual Shooting test, and show the effect through actual proofs.
First test the resolution and feel the photo during shooting It has a rich sense of hierarchy, and always surprises the details. Even the edge area of the composition is well grasped. The center resolution is well performed, and the detail sampling is very fine. The edge area is slightly lower than the center, but the overall effect is quite good, and it is difficult to notice if it is not specially enlarged.
Purple fringing phenomenon
As mentioned before, the Sony SEL20F18G has a good anti-dispersion performance. When shooting against the light, the edge contours are prone to “purple fringing” due to the alternating light and dark when shooting objects. When shooting scenery and scenery, the anti-dispersion ability of the lens directly affects the availability of the film, which is very important.
After zooming in on the sample, you can see that the Sony SEL20F18G is quite ideal in terms of anti-dispersion, and there is basically no obvious purple fringing on the edge of the film. This is due to the built-in low-dispersion lens to effectively alleviate the degree of dispersion in the shooting process, which is slightly but not obvious at the maximum aperture, and it is quite colorful.
Next is the actual shooting, in fact, after getting this lens , What came out of my mind was to take pictures on the Bund. The first reason is that this large wide-angle fixed focus lens can accommodate the landmark buildings on the other side of the Pujiang River, and the unique vision can create a broad texture. Second, as a “Huangpu native” who grew up on the Bund, I also want to take some photos of my “hometown”.
From the perspective of the filming effect, the scenery across the Pujiang River is very relaxing Is included in the lens. Landmark buildings such as the Oriental Pearl Tower, World Financial Center, Jinmao Tower, Shanghai Tower, and Shanghai International Convention Center, which are called the “four-piece kitchen”, are placed in one photo to create a magnificent visual sense.
enlarge the photo The details are still clear.
In addition to framing, color reproduction is very important. How to display and restore the bright colors in plants and flowers, SEL20F18G gives a good answer. The colors of the flowers in People’s Park are well represented, especially the texture details of the flowers are preserved in the photos, creating a spring and vibrant natural scenery.
The wide-angle lens has better depth of field and three-dimensional perception, in Nanjing Road The picture of the pedestrian street has rich layers and a three-dimensional effect. At the same time, the picture details and clarity are not lacking, and it is still clear.
As a member of the G lens family, it still has extremely high optical quality and performance, light and compact E-mount and the widest 20mm shorter in the current series and F1.8 large aperture, and Sony Its E-mount camera is very good. Scenery shooting, close-up shooting or Vlog video recording are all easy-to-use lenses. The excellent resolution performance is clearer in the details, so that the entire photo image is more clear and rich.
End——this is a suitable lens for photographers
The lightweight lens body is easy to carry out, and the weight of less than 400g is quite friendly for female photographers. In addition, the rich functions on the lens make it more convenient to adjust the parameters of the shooting process, without removing the camera and returning to the display to adjust.
