Sony’s Full-frame Widest Fixed Focal Length Lens Fe 20mm F1.8 G Experience Brief Review


[Bestbuy618 Digital Channel] With the release of the Sony FE 20mm F1.8 G, the number of Sony E-mount full-frame lenses has increased to 36, bringing the total number of E-mount lenses to 56. Furthermore, with a focal length of 20mm, it is the widest fixed focal length lens in the E-mount full-frame lens group. Based on its specifications, we can conclude that this lens designed for micro-single cameras is primarily compact, compact, compact, compact, compact, compact, compact, compact, compact, compact, compact, compact, compact, compact, compact, compact, compact It has a length of approximately 84.7mm, a maximum diameter of approximately 73.5mm, a filter size of approximately 67mm, and a weight of only 373g, but because of the 20mm focal length, many people immediately think of scenery, architecture, starry sky, and other large scene subject matter, so it will be classified as a niche lens.

However, with the proliferation of vlogs and short videos, this type of lightweight fixed focal length lens has emerged as the dominant shooting tool. The new lens was just received on this site a short time ago, so today we’ll experience the unique charm of the Sony FE 20mm F1.8 G. The FE 20mm F1.8 G retains Sony’s usual E-mount lens design style, with the focus ring in the front, the control area in the middle, and the aperture ring against the end.

The familiar three things are located in the center of the control area: the self/manual switch lever, the custom button, and the infinitely switch. The infinity switch allows users to adjust the aperture size gracefully when shooting video without fear of shaky images or noise interference during extreme adjustments. The maximum aperture of the lens is F1.8, the minimum aperture is F22, and the number of aperture blades is 9. The FE 20mm F1.8 G is compact in size, owing to Sony’s optimized optical design, which consists of 14 lenses in 12 groups, with 2 AA (Advanced Aspherical) lenses.

It also has an improved mechanical structure to ensure its overall light weight, fluoride-coated front and rear lenses for easy cleaning, and metal mounts for effective sealing and protection.

When mounted, the Lotus hood has no effect on the lens’ portable size, and the FE 20mm F1.8 G is similarly compact when paired with a body. *The Sony A7R4 is the body under review. As previously stated, the FE 20mm F1.8 G is optically optimized to produce high-resolution images. How does it work with the A7R4’s high pixel count?

The test results make it difficult to believe that this is only a G lens. At all apertures, the center of the lens image is quite sharp, with diffraction occurring only at the smallest aperture. At maximum aperture, the edge positions are slightly but not noticeably less sharp, and the edge image quality immediately improves when receiving F2 aperture, until diffraction problems appear at minimum aperture. The FE 20mm F1.8 G performs similarly to a GM lens in terms of resolving power, and is ideal for a high pixel body like the A7R4.

Close-up photography is made easier by the excellent resolution performance. By enlarging the photo, we can clearly see that every tiny detail on the stamen is well preserved, and the out-of-focus part of the bokeh is also very natural.

The FE 20mm F1.8 G has a maximum aperture of F1.8 and 9 aperture blades. The bokeh effect of the lens is very good, thanks to the use of 9 aperture blades, the maximum aperture of both the center and edge of the spot are very round, and the edge of the location of the spot does not appear obvious caliber etching, while the spot is very clean without seeing the phenomenon of onion rings. However, due to the small test props in the test, it is difficult to see the best starburst effect, forcing the editor to exit the test to continue.

Because it is a backlight shot, it is also a good test for the lens’ anti-glare and ghosting performance. From the sample shots, the FE 20mm F1.8 G’s anti-glare performance is very good, and although ghosting appears in the image, it is so slight that it hardly affects the viewing experience. The ability of such a lens to resist glare

And how about the dispersion control of the FE 20mm F1.8 G at high contrast ratios? Let’s put it to the test by gradually reducing the aperture. The test results show that the dispersion of this head is very good, both in-focus and out-of-focus, with no purple edge on the edge of the object highlights.

Finally, let’s look at the lens’s dark angle and aberration control. In terms of dark corners, the dark corners are more visible at full open aperture, but they disappear after two stops. In terms of aberration, the FE 20mm F1.8 G has very good control for a wide-angle lens, with only a slight barrel distortion. Only a slight barrel distortion is visible.

Another noteworthy feature of the FE 20mm F1.8 in this review is how quickly it focuses. This is due to the fact that it uses the same XD linear motor as the G Master lens. The dual XD linear motors improve autofocus speed, accuracy, and tracking performance, which is exactly what video creators require. Motion pictures are now the dominant way to shoot for today’s shooters, and the FE 20mm F1.8 is light enough to carry any equipment without burdening the shooter when holding it for long periods of time.

Powerful focusing performance with the camera’s eye recognition focus, allowing users to avoid the hassle of defocusing and focus their energy on the creation.

Summary: The FE 20mm F1.8 G’s overall performance as a G lens is impressive, and it differs from traditional G lenses in terms of high quality, even approaching the threshold of GM lenses. Although many people have mixed feelings about its focal length, in practice, the ultra-wide 20mm focal length, combined with the 0.19m closest focusing distance and the F1.8 large aperture, makes it suitable for a broader range of subjects. Furthermore, the FE 20mm F1.8 G’s wide field of view, small size, and powerful focus make it an essential shooting tool for video creators.
