Sony 20mm F1.8 G - all the information and analysis of the new luminous wide angle camera
Sony continues to expand the catalog of lenses for its E-mount full-frame cameras with the presentation of a new wide-angle lens that stands out for its viewing angle as well as its brightness, all in a compact size. We are talking about the Sony 20 mm F1.8 G, a lens that B&H is going to present to you, which B&H exerts have already had the opportunity to test (and we will tell you what they have found).
But, before we get into the matter, let's take a closer look into where the new objective would be located in its catalog, and who it has as competition. Below, you can read B&H initial impressions about the lens.
With two advanced aspheric and three ED elements, Sony promises outstanding corner-to-corner image quality, as well as fast autofocus thanks to XD (extreme dynamic) linear focus actuators. This lens is capable of resolving detail well when paired with sensors of higher resolution than the 60MP a7R IV. And the lack of any haziness indicates that contrast is very high, even at this aperture and close focus distance.
The new lens carries the initial G in its name, which identifies a range of quality objectives that is only one notch below the ‘G Master’. Sony claims that they are responding to the demands of its users, and promising images with high resolution from corner to corner and in any situation, with fast and precise autofocus.
Due to its wide coverage, it is an ideal lens for landscape photography, architecture and astrophotography, as well as low light situations in general, due to its high luminosity (Æ’1.8). Its optical construction is based on 14 elements distributed in 12 groups, and has a circular aperture diaphragm with nine blades, which augurs good bokeh.
All this in a sealed body that boasts of being small and light, a weight of 373 grams, and measures 84.7 x 73.5 mm, with a filter diameter of 67 mm. Another interesting feature is its focus distance, which is 18 or 19 centimeters, depending on whether we focus on manual or automatic (and it allows a magnification ratio of 0.22 / 0.20, respectively).
