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.

Pros: Weight, Sharpness, Performance

Cons: In the rest position it is at 40 mm

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.

Pros: Image Quality, Focal Range, 2.8 Fixed

Cons: At the moment none

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.

Pros: price-quality, compact and lightweight.

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.

Pros: Weight, autofocus, sharpness

Cons: Lack of diaphragm dial and programmable button

Opinion: Light and compact, already very sharp at full opening but improves by closing a little. It has an autofocus like the original sony lenses for more quiet. The fact that when zooming towards the 20mm from 40mm extends very little means that on the gimbal you do not lose the balance. I found it really good also on a constructive level. I use it in the video and I must say that at the moment there is nothing like this price.

Pros: Excellent weight and size, therefore: easy handling. Barely imperceptible distortion, af fast and responsive, it has no vignetting.

Cons: At the moment: nothing!

Opinion: A great all-rounder, at least for my needs. Compact and lightweight, already very good at f 2.8, beyond it becomes sharp. Through the "TAMRON Lens Utility" software, by connecting the lens from its connection port via the USB connection cable, you can customize the functions and update the lens firmware. Personal customization offers flexible shooting options to suit your shooting situation, such as photography or videography. With the help of the personal configuration, the lens can be optimally adapted to the respective shooting situation, such as photos or videos. Price-performance=9.

Pros: Nesting, very little distortion, af

Cons: Nothing relevant at the moment

Opinion: Excellent lens with "right focal lengths"! The 20 40 for me is the right wide-angle compromise. The 16mm was too wide for my photographic style and the 35mm is my lens with which I shoot practically everything. So, with the 20 40 I bring home most of the work: weddings, shootings and events and panoramas. The constant 2.8 aperture makes it bright and suitable for everything. I haven't noticed flare or aberrations yet. Sharp in the center already at full opening and good at the edges. At least, my specimen is. If you close at f4 it is a blade. Very responsive AF. Coupled with my Tamron 35 150 2 2.8 I can cover any type of event. In my opinion it can be the right compromise for those like me who are used to working with a fixed 35 because for speed you can easily get to a 20 without changing lens or carrying two camera bodies.
