Pros: Focal range, compactness, price.

Cons: It doesn't have the Nikon Z mount, as well as a few others!

Opinion: But what does Nikon do? It blocks the possibility of mounting third party lenses to sell your lenses... but perhaps this way it sells fewer cars! Released almost simultaneously this and the new Nikon Z 24-105 which is f4-7.1! Nikon also has the excellent 24-200 f4-6.3, but there is a big difference between 20 and 24! Still excellent piece, super versatile, very comfortable! Brava Sigma!

Pros: Weight, resolution from 35 mm upwards, construction, focal range,

Cons: Annoying distortion but perfectly corrected in Camera Raw, slight drop in resolution to 20mm (f3.5), improves from f11

Opinion: This is a part of the review I'm doing on behalf of Sigma Italia about this lens. If you want specific info please write to me. Thank you! "The 20-200 is a lens suitable for everyone but Sigma in this case has winked at the landscape architect and not at the "usual" hunter of sunrises and sunsets but at the one who tirelessly climbs up mountain paths or undertakes long walks in the undergrowth. In just 540 gr you have a complete photographic kit that starts from the extreme wide angle and reaches the tele. We are not facing an Art series lens but the quality of this lens is surprising and as a landscape photographer I didn't even worry too much about the brightness expressed in apertures. The AF has proven to be responsive. The general resolution is definitely good and you can barely notice any differences with more valuable optics, in fact in the field they are not noticeable at all. Flare resistance is within the norm considered the focal length. This is a one-of-a-kind zoom and has to fit in anyone's bag, it's a great all-rounder."

Pros: I think every photographer's dream is from 20 to 200 in a single lens, light and really small. Decent image quality good containment in camera (Sony) of distortion and vignetting, otherwise noticeable at 20mm.

Cons: Zoom ring really hard, so much so that the lens lock is useless. A note on the lens hood that is well done but that in order not to vignette at 20 mm is very small making it almost useless, especially in the winter months when the sun is always low.

Opinion: Taken as a replacement for the tamron 28-200 to be able to leave the 20-70 at home and have only the camera around your neck with only one lens. How are you? Roughly with the same general quality as the tamron which however was 2.8/5.6, considering however that to have a good quality with this kind of lenses you have to ask at f8 at least and therefore little changes. Maybe it's because I'm a certain age, but I couldn't stand to go around with a backpack full of heavy lenses, which will have a better image quality (not that much, especially considering the huge price difference), but that for those like me who make a photographic genre of "seize the day" and you don't always have time to replace the lens under penalty of losing the photo. I have done many tests in these days and by setting the colors and image parameters in the camera (Sony A7 IV) I can say that I am satisfied with the images it returns. A great extra gear for those who do street. I leave out all the technical speeches, abberations, distortions, vignetting and I leave it to the machine to solve them, which does it very well. If you don't have special needs, but like to focus on the content of an image knowing that you will always know that you have the right focal length at the right time already in the camera, that's a lot of stuff! Edit post: I don't know if it's just my impression but after the latest firmware (6.01) on Sony A7 IV the vignetting is no longer correct as before.....

Pros: Practicality, versatility, lightweight, compact, good overall image quality.

Cons: A bit of distortion at 20mm, slight drop at the edges at wide-angle focal lengths but nothing excessive, a bit dark, zoom ring that turns in reverse compared to Sony

Opinion: The lens is well built, plastic yes, but not cheap, in line with contemporary Sigma. Dimensions and weight are relatively compact for the type of lens. Well-frictioned dials, a bit hard in the first part, that of the zoom. Average lens hood, attaches well. Let's move on to the impressions about the photos. Sharpness, also excellent at t.a. from 35mm to 200mm even at the edges, while from 20mm to 28mm it remains excellent in the center while it drops a little at the edges (nothing tragic safely usable) however it is advisable to close a stop if you want a uniform performance. The discourse of sharpness applies to both short and long distances. In general much much better than I expected on 42mpx. (I use a Sony A7R3) Chromatic aberrations in the norm, pretty good blur and good flare resistance. Backlit star that is not bad at all between f14 and f18 especially in wide-angle focal lengths. Always consider that we are talking about an all-rounder zoom. The only drawback to be picky is a bit dark and with a rather important distortion and vignetting between 20 and 28mm but nothing impossible to correct in post. (Currently there is no profile for lightroom, I have used for now the profile of a 28-200 sigma modifying it slightly) Precise and fairly fast AF. The macro capabilities of 1:2 from 20mm up to 85mm are remarkable. In short, I would say that it is worth what it costs, nothing to do with the "zoomons" built up to a few years ago. I don't regret the sony 24-105 I traded it in.
