Sony Fe 20mm 1 Eight G
In the first instance, the shapes are properly rounded and very easily crammed. In the second example, we see an anomaly, darkish blobs, that results a very small portion of the frame within the review lens. Those stars are actually not spherical, although they aren’t unusually distorted for a wide-aperture, broad-angle lens. The picture below is a 100% crop taken from the top-left corner of an a7R III body. In the examples below, have a look at the fringing colors in the out of focus specular highlights created by the neutrally-colored topics. A comparatively common lens aberration is axial CA, which causes non-coinciding focal planes of the assorted wavelengths of sunshine, or more merely, different colours of light are focused to different depths.
The 24mm lens has modestly less vignetting and exhibits fewer flare results at slender apertures in our take a look at. The 20mm lens has slightly less geometric distortion, barely much less lateral CA, and less color blur. Until now, the widest Sony prime for A7 and A9 series cameras was the FE 24mm f/1.4 G Master.
Fe 20mm F1 8 G
The FE 20mm provides full-frame coverage, one thing absent from Sony’s other 20mm prime, the E 20mm F2.eight, which is built for the company’s APS-C sensor a6000 series cameras. You can nonetheless use the FE 20mm on an a6600 or comparable digicam if you would like, but images won’t have the same broad angle of view as when the lens is paired with a full-frame camera. The Sony FE 20mm F1.eight G is a sharp, shiny lens with a wide angle of view. It’s a prime-finish performer and a fine addition to your camera package. It delivers astonishing levels of sharpness proper across the entire image body and into the intense corners, which is a real problem for such a wide-angle lens.
- Lateral chromatic aberration is so negligible that there’s hardly any shade fringing, even at towards the extreme corners of the frame.
- I was shocked at how nicely the 20mm G carried out as I was really anticipating it to be significantly worse than the 24mm G Master however that’s definitely not the case.
- The first wave of lenses had been adapted DSLR lenses, not this one.
This ring has respectable smoothness and the eighty° of Linear Response MF rotation is excellent for precise manual focusing at all distances. This is a nicely-applied focus-by-wire design with adjustments being moderately-easily made. This lens design incorporates two AA components and three ED (Extra-low Dispersion) glass parts as seen below. While not perfectly spherical, the corner circles usually are not very distorted. As the aperture narrows, the doorway pupil measurement is lowered and the mechanical vignetting absolves with the shapes changing into spherical.

It actually trumps the Tokina which was considered one of my biggest points with it – it never felt like an f/2.0 lens. Single exposures had been quite noisy as a result of heavy vignetting and poor gentle transmission, meaning it wasn’t the best lens for astro timelapses. Below is an instance of the Sony vs. Tokina at f/2.0 with all other settings stored the same.
