In truth I have to say I fairly like this angle of view for this genre. Sharpness at 1.8 is already good, however you’ll be able to stop down to get even better results whereas also having more of the object in focus. The short distance will assist to maintain a great amount of shallow depth of area even at f/four and the lens exhibits an excellent character with nice out of focus areas. Zeiss sells a wide prime for the system, the Batis 18mm f/2.eight, nevertheless it costs $1,500. Most different options on this focal length are zooms, none of which supply an f/1.eight design.
The 24mm lens has modestly less vignetting and reveals fewer flare effects at slender apertures in our take a look at. The 20mm lens has slightly less geometric distortion, barely less lateral CA, and fewer color blur. Until now, the widest Sony prime for A7 and A9 series cameras was the FE 24mm f/1.4 G Master.
Sony Fe 20mm F
The FE 20mm provides full-body protection, something absent from Sony’s other 20mm prime, the E 20mm F2.8, which is constructed for the corporate’s APS-C sensor a6000 sequence cameras. You can still use the FE 20mm on an a6600 or comparable camera if you would like, but pictures won’t have the same broad angle of view as when the lens is paired with a full-frame camera. The Sony FE 20mm F1.8 G is a sharp, shiny lens with a wide angle of view. It’s a prime-finish performer and a fantastic addition to your camera equipment. It delivers astonishing ranges of sharpness proper throughout the whole image body and into the intense corners, which is a real challenge for such a wide-angle lens.
- You can see that there is some sagittal and tangential astigmatism but the aberration is basically small and likewise reveals good enchancment if you stop down.
- For those that don’t know, sagittal flare is the elongating of pinpoint light sources like stars.
- I usually carry a hard and fast 20mm as an alternative of a sixteen-35mm zoom to avoid wasting weight, and if I carry a 20mm, usually I only carry an 85mm and depart everything else back at the studio — no 35 or 50mm needed.

This ring has respectable smoothness and the 80° of Linear Response MF rotation is excellent for exact guide focusing at all distances. This is a properly-carried out focus-by-wire design with adjustments being reasonably-easily made. This lens design incorporates two AA parts and three ED (Extra-low Dispersion) glass parts as seen under. While not completely round, the nook circles usually are not very distorted. As the aperture narrows, the entrance pupil dimension is decreased and the mechanical vignetting absolves with the shapes becoming spherical.

It certainly trumps the Tokina which was one of my greatest issues with it – it by no means felt like an f/2.zero lens. Single exposures have been quite noisy because of the heavy vignetting and poor gentle transmission, which means it wasn’t the best lens for astro timelapses. Below is an example of the Sony vs. Tokina at f/2.0 with all other settings saved the same.
