It isn’t quite as good as the very best astro-lenses but still good enough to take astro-images you can enlarge quite a bit.į/2: Contrast is high from f/2. I was surprised by the pretty decent coma correction of the FE 2/28. The lens is not a true 28mm lens, more like a 26mm lens so after distortion correction you have the field of view of a 28mm lens. It is not so bad that I have noticed it in my landscape images, but if you shoot raw you will have to correct it for any image with a straight line in it and this will cost some resolution.

raw file straight from LR without any corrections | click for full resolution The Sony shows pretty severe barrel distortion and is clearly meant to be electronically corrected. Vignetting also has a negative effect on bokeh. If you use the FE 2/28 wide open vignetting is easily noticeable.For most images it will actually have a positive effect on the image since it leads the attention away from the corners but there are applications like astro-photography where this becomes an issue.
I also see a little blue-shift towards the corners which has never been an issue in the field. My figures are what I measure in LR without any profile applied by me but it includes a forced correction of about 0.5 EV so the true figure is above 3 EV. The Sony FE 2/28 shows strong vignetting which is no surprise for such a small lens. The Sony FE 2/28 shows good flare resistance in most scenarios but under more extreme scenarios some lenses perform better.
Scenario 1: Close Focus, semi demanding background great bokeh at a very short distance the bokeh in the center is still very smooth but the corners deteriorate a little At this distance bokeh is good in the very center and okay outside of it It is very smooth at short distances, still pretty good at portrait distances and more nervous at long distances. The FE 2/28s bokeh is smooth for a wide-angle lens. On the a7III I would expect excellent performance. On my a7II the small Sony is quite responsive when there is enough light but it slows down noticeably in lower light. So you will be limited mostly by your camera. AutofocusĪF worked well and precise, it is one of the faster FE lenses.

So manual focus works okay but it isn’t very enjoyable (says a hardcore manual lens user). Manual lenses where the focusing ring is coupled directly to the focusing helicoid are nicer and faster to use but with a little patience you can focus the FE 2/28 very precisely. If I turn it slowly it takes more than 360 degrees (one full turn) to change focus from the close focusing distance to infinity. It also feels like there is a small lag between the moment when you turn the focusing ring and when the lens reacts. The problem here is that it matters how fast you turn the focusing ring, so if I turn it by 20 degrees very fast the focus changes from 29 cm to infinity. on my Alpha 7Īs mentioned before the focusing ring feels nice, what I don’t like too much is the focus by wire implementation. Handling is quite good overall, the focusing ring is very wide and feels nice, the lens hood is just the right size: it protects the front lens effectively without adding too much bulk. The FE 2.8/35 is even shorter and lighter but also a stop slower. The lens is very small for a fast 28mm lens, above you see it besides a much bigger and heavier Minolta MC 2/28 and a still bigger Minolta 2.8/28. At 200g the lens is also the lightest 2/28mm lens I know of. plastic at the front, metal at the back Size,Weight and Handling Minolta MC 2/28 | Minolta MD 2.8/28 | Sony FE 2/28 | Canon nFD 1.4/50 Sony’s ZA lenses have much nicer hoods.Īll in all I think the build quality is okay but nothing to get excited about. The lens hood is a bit flimsy, rather thin and cheap plastic, it is the same as the one for the old E 3.5-5.6/18-55 Kit lens. The focusing ring feels very smooth but it offers enough resistance and it has zero play. This design looks quite nice but the softer aluminium easily attracts scratches of which my copy now has quite a few. The Fe 2/28 has a metal mount. The focusing ring and the lower part of the lens hull are made from aluminium.The upper part of the lens (a bit more shiny in the picture), the filter thread and the intestines are made from plastics.
