Sony Fe 20mm F

For photographs with a protracted exposure they’re helpful, even with assistance from impartial density filters, and you may additionally get one of the best-looking sunstars out of the lens at f/16. They’re pretty good at f/11 and f/8 as nicely, just not fairly as outlined. I tested the FE 20mm F1.8 G together with the 60MP Sony a7R IV and software from Imatest.

• the whole z-mount lens lineup has misplaced out on af efficiency, as a result of Nikon remains to be utilizing variations on the old stepper focus motor.
• Perhaps my only complaint about this lens is that it’s maybe too sharp, which says a lot.
• Only in the full-frame corners is it a bit softer should you’re trying with a microscope at 60 megapixel A7R IV images, and those sharpen right up as stopped down.
• This lens has no Optical Image Stabilization or OSS , however does work with no matter in-body sensor-shift stabilization your camera may or might not have.

If Sony, which is a simple electronics company, can produce such an optical marvel, I can solely imagine what a 20mm F1.8 lens produced by Nikon, a true optical company, would look like. While some find these cross model comparisons of curiosity, I could not care much less. Either Iike the lens or I do not – I’m not going to change whole camera methods over it – simply look for a better lens, and spend slightly more too more than likely.

Can I also add that as a result of the mount is substantially smaller than, to say, the Z mount, lenses are not forced to be greater than they need to be? The notion of broad angles for panorama solely could be very retro. Nikon does get these lenses into people’s hands earlier than the discharge, by the way in which. Our comments don’t solely concern the middle of the frame, however peripheries as properly, the place sharpness is maintained quite well at F1.eight, but very nicely by F2.8. We also comment negatively on bokeh performance at peripheries, though we solely surmise it, based mostly on brighter-edged OOF highlights in our lab setup. Now a 20mm lens is only “bordering extremely-extensive” with significantly better optical efficiency than most likely ever earlier than, but old information stay the identical as at present.

Stars shall be bigger in the body at 24mm, so it’s at a little bit of an obstacle on this comparison. The 24mm is nearly perfect at f/1.four, however you possibly can see astigmatism and somewhat coma on the brilliant stars (although it’s uncommon you should have a star this shiny in the corner of the body). The 24mm additionally exhibits more chromatic aberration (colour-fringing) than the 20mm, however this could easily be corrected in Lightroom. One of the primary things I seen is that the Sony was noticeably wider than the Tokina and Samyang 20mm lenses that I had been using. Through slightly little bit of measurement, I labored out that the horizontal subject of view was 86.1° which puts it nearer to being a 19mm lens (86.9°) than a 20mm lens (84.zero°).

It performs much better than the Tokina 20mm Firin which has larger astigmatism wings and a bit more chromatic aberration. Sadly the Tokina doesn’t present much enchancment when stopping right down to f/2.8 from f/2.0 both. Not to say that the Tokina is a foul lens at all, simply that the Sony is an excellent one.
