Fe 20mm F1 Eight G
For photographs with a long publicity they are useful, even with the aid of impartial density filters, and you will additionally get the best-wanting sunstars out of the lens at f/sixteen. They’re fairly good at f/eleven and f/8 as well, just not fairly as outlined. I tested the FE 20mm F1.eight G along with the 60MP Sony a7R IV and software from Imatest.
- Normal is for the scene to alter size within the body as focus is pulled from one extent to the other, known as focus respiratory, a change in focal size ensuing from a change in focus distance.
- While the A setting of the aperture dial implies that you will get Program or Shutter-preferred exposure mode at that setting, what it actually does is move the aperture setting to the digicam’s front management ring somewhat than on the lens.
- On the soccer subject contained in the observe, the “20” yard line quantity seemed acceptable to photograph at this focal size though finding an excellent digicam place proved challenging.
- I like to take a look at focal lengths in comparison format and, since this lens has just one focal length, I’ll borrow a comparability from the Canon EF 16-35mm f/4L IS USM Lens evaluate.
If Sony, which is a simple electronics firm, can produce such an optical marvel, I can only imagine what a 20mm F1.eight lens produced by Nikon, a real optical firm, would appear to be. While some discover these cross brand comparisons of curiosity, I couldn’t care much less. Either Iike the lens or I don’t – I’m not going to modify entire digital camera techniques over it – just search for a greater lens, and spend slightly more too most probably.
Sony Fe 28mm F2
Can I additionally add that as a result of the mount is substantially smaller than, to say, the Z mount, lenses aren’t pressured to be greater than they need to be? The notion of broad angles for landscape solely could be very retro. Nikon does get these lenses into folks’s arms before the discharge, by the best way. Our feedback do not only concern the middle of the body, however peripheries as properly, where sharpness is maintained fairly nicely at F1.eight, but very well by F2.eight. We additionally remark negatively on bokeh efficiency 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 a lot better optical performance than probably ever earlier than, but old news keep the same as today.
I like to look at focal lengths as compared format and, since this lens has just one focal size, I’ll borrow a comparison from the Canon EF sixteen-35mm f/4L IS USM Lens evaluation. All words, images, videos and format, copyright Gordon Laing. This is a lot better than the Tamron can do which takes double the time to focus and is searching a bit across the point of sharpest focus. Here’s a shot shot at f/eleven when the solar is touching the sting of the houses and tree line, inflicting this nicely defined sunstar.

With this 20mm f/1.8 it’s amazing how clear and sharp is the magnified guide-focussing image in my Sony A7R IV, especially for the night time pictures you see above. Manual focus pops right-in, even in near pitch-black evening circumstances. I focus at f/1.8 after which cease down for depth-of-subject for time exposures. Sure, nice engineering effort, but my comment was specific about advertising. Others have commented, how Nikon did not get a lot protection for their 20mm lens. Canon’s 17 and 24 TSE lenses have impressed me daily I even have used them since their release.
