The following opinions have been automatically translated with Google Translate.
Pros:I confirm all the praise of those who preceded me, extremely versatile, light and excellent quality optics.
Cons:Maybe reliability? The 20mm polarizer is clearly visible at the 4 corners of the frame.
Opinion:Semi-new, regular import, yesterday it crashed! That is, it normally flowed from about 40 to 28 and at 28 it froze. Insisting a little it unlocked but f-value detection and autofocus no longer worked! The incident recalls the defects complained of to the Olympus 9-18, it is as if a flexible circuit gets stuck in the zoom sliding mechanism and then inevitably breaks. At least... It is under warranty.
Pros:Small, lightweight, f2.8, great microcontrast, sharp from side to side, extremely versatile. Irreplaceable optics
Cons:At the moment none
Opinion:Small, very light, it ranges from the wide-angle of 20 mm to the medium-telephoto of 40, and it does it well, very well. Distortion at 20 perfectly correctable in post, a unique lens. I can't find a fault. Nice little filter thread, a perfect lens for the mirrorless system. You will never take it off the camera except to switch to a longer focal length.
Opinion:I had some doubts before buying it also because I didn't have the opportunity to try it before but as soon as I arrived, mounted and tried I was immediately impressed by this optics. The distortion at 20 mm is minimal but on the other hand the rendering even at the edges at full aperture is really very good considering that it is a zoom. The only real flaw it has is that in the rest position (i.e. zoom not extended) it is at 40 mm while logic would have liked it to be the other way around, but on balance it is not a real defect. Good news for night owls: from about F9 the lights become stars and at full aperture the stars do not suffer noticeably from coma or aberrations.
Opinion:An almost one-of-a-kind lens, light and compact that starting from 20mm allows you to leave even the wide-angle lens at home. For many genres it could be the only lens to carry around, possibly flanked only by a telephoto lens, if necessary. Excellent image quality, quiet and precise autofocus, nice blur at 40mm, plus the close focusing distance allows you to get creative. With the fixed 2.8 it adapts very well to indoor situations with low light and night photography. It's become the lens that I always keep attached to my camera. On the A74 I can use it in apsc with the simple press of a button, reaching 60mm equivalent. Maybe if you look closely in some situations you can detect a slight vignetting or a slight distortion, but overall nothing particularly noticeable and that cannot be solved with a click.
Cons:Unstabilized, the zoom is done by retracting the lens.
Opinion:Excellent lens I use it in combination with the tamron 50-400mm. The only flaw is the lack of stabilization and therefore becomes mandatory on the camera body in particular situations. For the rest excellent quality / price even if slightly plastic. Very light. The image is already sharp at full aperture and the focus is responsive within the limits of a third-party.
