Sony Fe 20mm F
For pictures with an extended exposure they’re helpful, even with the aid of impartial density filters, and you will additionally get one of the best-wanting sunstars out of the lens at f/16. They’re fairly good at f/11 and f/eight as nicely, just not quite as outlined. I tested the FE 20mm F1.eight G together with the 60MP Sony a7R IV and software from Imatest.
- It jogs my memory Fuji’s superb 16mm f1.four lens, but I choose this one on my A7R3 due to the broader angle and the scale.
- the entire z-mount lens lineup has misplaced out on af performance, as a result of Nikon remains to be utilizing variations on the old stepper focus motor.
- Only within the full-body corners is it a bit softer should you’re looking with a microscope at 60 megapixel A7R IV pictures, and those sharpen proper up as stopped down.
- This lens has no Optical Image Stabilization or OSS , however does work with no matter in-physique sensor-shift stabilization your digital camera could or might not have.
If Sony, which is a straightforward electronics firm, can produce such an optical marvel, I can only think about what a 20mm F1.8 lens produced by Nikon, a real optical firm, would appear to be. While some discover these cross brand comparisons of interest, I couldn’t care much less. Either Iike the lens or I do not – I’m not going to switch entire digital camera techniques over it – just look for a better lens, and spend slightly extra too more than likely.
Full Frame Fe G
Contrast and colour rendition are equally impressive, even when capturing broad open at f/1.8. The Sony FE 20mm f/1.eight G lens is a large-angle prime lens, with a comparatively brilliant aperture of f/1.eight. The E-Mount lens covers the total-frame sensor, but may also be used on Sony’s APS-C mirrorless cameras, giving a crop to 30mm in 35mm equal phrases. We tested the Sony FE 20mm f/1.eight G lens on the Sony Alpha A7R III, 42mp digital camera. So how nicely did the Sony 20mm f/1.eight G lens deal with the night time sky?
Stars shall be bigger in the body at 24mm, so it’s at a bit of an obstacle on this comparability. The 24mm is almost excellent at f/1.four, however you possibly can see astigmatism and somewhat coma on the brilliant stars (although it’s uncommon you’ll have a star this bright within the nook of the frame). The 24mm also reveals more chromatic aberration (color-fringing) than the 20mm, however this will easily be corrected in Lightroom. One of the first things I seen is that the Sony was noticeably wider than the Tokina and Samyang 20mm lenses that I had been utilizing. Through slightly little bit of measurement, I labored out that the horizontal field of view was 86.1° which places it nearer to being a 19mm lens (86.9°) than a 20mm lens (84.0°).

It performs a lot better than the Tokina 20mm Firin which has larger astigmatism wings and a bit extra chromatic aberration. Sadly the Tokina doesn’t show much enchancment when stopping down to f/2.eight from f/2.zero either. Not to say that the Tokina is a foul lens at all, simply that the Sony is an excellent one.
