Fe 20mm F1 8 G
For pictures with a protracted publicity they’re helpful, even with assistance from neutral density filters, and you may also get the best-looking sunstars out of the lens at f/16. They’re fairly good at f/eleven and f/8 as nicely, simply 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 amazing 16mm f1.4 lens, however I prefer this one on my A7R3 due to the broader angle and the dimensions.
- the whole z-mount lens lineup has lost out on af performance, as a result of Nikon remains to be using variations on the old stepper focus motor.
- Only in the full-body corners is it a bit softer when you’re trying with a microscope at 60 megapixel A7R IV images, and those sharpen proper up as stopped down.
- This lens has no Optical Image Stabilization or OSS , however does work with whatever in-physique sensor-shift stabilization your camera might or may not have.
If Sony, which is a simple electronics company, can produce such an optical marvel, I can only imagine what a 20mm F1.8 lens produced by Nikon, a real optical company, would seem like. While some find these cross model comparisons of interest, I couldn’t care much less. Either Iike the lens or I do not – I’m not going to modify whole digicam techniques over it – simply search for a better lens, and spend somewhat more too most likely.
Sony Fe 28mm F2
Can I additionally add that as a result of the mount is considerably smaller than, to say, the Z mount, lenses are not forced to be greater than they need to be? The notion of wide angles for panorama solely may be very retro. Nikon does get these lenses into people’s hands earlier than the discharge, by the way in which. Our feedback don’t only concern the middle of the body, but peripheries as properly, the place sharpness is maintained fairly well at F1.8, however very properly by F2.eight. We additionally comment negatively on bokeh efficiency at peripheries, though we solely surmise it, based on brighter-edged OOF highlights in our lab setup. Now a 20mm lens is only “bordering ultra-broad” with significantly better optical efficiency than in all probability ever earlier than, but old news stay the same as today.
Stars shall be greater in the frame at 24mm, so it’s at a bit of an obstacle on this comparison. The 24mm is almost excellent at f/1.four, however you can see astigmatism and somewhat coma on the bright stars (although it’s uncommon you will have a star this bright in the corner of the body). The 24mm additionally reveals extra chromatic aberration (colour-fringing) than the 20mm, but this could easily be corrected in Lightroom. One of the first things I noticed is that the Sony was noticeably wider than the Tokina and Samyang 20mm lenses that I had been using. Through a little 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 (eighty four.zero°).

With this 20mm f/1.eight it’s amazing how clear and sharp is the magnified handbook-focussing picture in my Sony A7R IV, especially for the night shots you see above. Manual focus pops proper-in, even in near pitch-black evening conditions. I focus at f/1.8 after which stop down for depth-of-field for time exposures. Sure, good engineering effort, however my remark was specific about advertising. Others have commented, how Nikon didn’t get much protection for his or her 20mm lens. Canon’s 17 and 24 TSE lenses have impressed me daily I have used them since their release.
