Pros: Weight, build quality, image quality, overall size, good focal length range

Cons: Lack of stabilization, dubious tropicalization, absence of the aperture ring

Opinion: Excellent zoom almost everything does given the focal ranges, very close in optical quality to 24-70 or 28-105 without being as huge. I think that for a small camera like my Lumix S9 (or the original Sigma fp/fp-l/bf) it is the best before it becomes frankly uncomfortable to shoot with it (and we are already close to the limit). The quality is excellent at all focal lengths and at all apertures, if taken in L-mount there are no distortion problems. It extends but not too much, in case of travel excellent as the only lens to carry with you. Expensive but in the second-hand market you are starting to find it at reasonable prices (

Pros: File quality, focal range, weight, size.

Cons: Still high cost, absence of the aperture ring, absence of stabilization, in my case big front focus problems.

Opinion: Handy lens, low barrel extension, good construction and low weight. As for the 16-28mm it lacks the aperture ring, very convenient if you work with Sigma FP. Unfortunately the cost is still very high but being practically the only lens with this focal range (excluding the art 24-70 version, L-Mount version) there is little to do... Bought for work needs at the expense of the 65mm f2 that I sold (reluctantly). The file is good, not at the level of the fixed. Rated 8. - - - - - Correction: After using it at a conference, I wrote the review that you can read above. Then used for an important job (sure of the previous performance) I found myself with blurred photographs in broad daylight, with times so high as to make blurry or even blurry impossible... It would seem to be back and front focus... Now I regret the 65mm. Rated 4

Pros: Compact, bright, fast AF, creamy bokeh, sharpness.

Cons: Only partially tropicalized, ghosting at 2.8 at the minimum distance of maf.

Opinion: Fantastic lens, I use it on panasonic S5, on which it works exactly as a native lens, so fully functional AF as well as all the corrections in the camera, even firmware updates are done as for lumix lenses. At 2.8 on all focal lengths it is already very sharp in the center and good at the edges. Closing at 4 or 5.6 it becomes perfect from edge to edge, perhaps only at 70mm at the extreme edges it is less sharp, but just to want to be picky. It has a creamy blur that I like very, very different in this from panasonic zooms (especially the 24-105) Different speech when you are close to the minimum distance of maf: the images are soft enough to seem out of focus, which had happened to me only on the fuji x100f. Closing at 4 improves, at 5.6 it resolves definitively ... All in all when you are so close to the subject, a bit of PDC is not even bad. It has a rubber gasket around the bayonet, but the rest of the body is not tropicalized, however, when it rains I always keep the car inside the good old plastic "waterproof" with an elastic band around the hood, so as not to have problems. Ultimately an extremely valid and versatile lens, I use it especially indoors or with little light, where combined with the portentous iso seal of the S5, I definitively solved every problem of photos with difficult light and combined with the new noise reduction software through AI, does not make me feel the lack of fixed lights.

Pros: Compact, sharp, excellent optical and build quality, constant f/2.8

Cons: Nobody

Opinion: I use it on A7C with pleasure.. Convenient and comfortable to carry around. No problem even after a full day of use. The materials used are of high quality.. a pleasure to use. Easy-to-grip rubberized zoom bezel. Remember to hold the hood ONLY at the short petals .. It works great! Combined with the A7C I have excellent sharpness, well-controlled chromatic aberrations, super fast and accurate autofocus. For my use (travel/portraits with shallow depth of field, use in low light conditions) I am very happy and satisfied!

Pros: 2.8 , color rendering , focusing distance

Cons: the lens drops drastically to 70mm

Opinion: Lens with beautiful colors, between 35 and 60 gives the best of itself, drops conspicuously to 70mm in which much of the detail is lost making everything a little too messy, despite this in my opinion it turns out to be a lens of absolute quality .... Compared to its competitors it is lighter and smaller, something to consider for its purchase

Pros: Weight, image quality, f2.8

Cons: At 70mm it drops slightly

Opinion: A lens that from 40 to 60mm exceeds many fixed, sharpness and compactness and lightness, on the Panasonic s5 seems to have a compact, for those looking for a light and sharp lens and those like me who have a super wide angle and the top as a combination, at 70mm drops slightly but this applies to all the optics on the market, I combined the 14-24 f2.8 art sigma and this 28-70 f2.8 and I must say that it is a fantastic combination, at 50 mm exceeds in image quality of many fixed 50mm that I had.

Pros: Mounted on a7III goes which is a pleasure. Light and very sharp, in some cases even more than the 45mm 2.8 sigma that I also own. For me the 28mm of minimum focal length is more than enough for an all-rounder, I associate it with the fixed 24mm or the 17-28 and the problem does not arise. I prefer so rather than having almost a kilo all mounted in the room

Cons: Not stabilized

Opinion: Already written everything in the pros. I am very happy with this all-rounder, compact light and quality. That's what I need to shoot at an event. If I had to shoot only with a focal length (and I love fixed) I would use the 35mm, so I rarely feel the need to shoot at less than 28mm and indeed in some respects I prefer not to go below. If we then put that these 4mm less are equivalent to almost half the weight compared to the older brother, I have no doubt about the choice made.

Pros: Compactness, lightness, build quality, optical quality at normal focusing distances, constant aperture at f 2.8

Cons: Optical quality at minimum distances

Opinion: It is an excellent all-rounder lens that sacrifices the lower focal length to achieve compactness and lightness, without sacrificing the build and optical quality. 28 mm is not the maximum for a wide angle, it is a bit the minimum union, but in most situations it is enough. Personally if I move with the complete kit I also have in my bag a fixed 21 mm f2.8 if just 28 are not enough for me. In any case, the coupling weighs less than a 24-70 f2.8. The optical quality expires significantly if the minimum focusing distance is to be used, especially at 28 mm at open apertures. But it is not a macro lens and it can be there. As for the hood, I too at the beginning had difficulty in diseading, but then I learned to hold it only in correspondence to the short petals and it comes away that it is a pleasure. The excursion in length is very small, which I very much like. The focus and focal variation rings are in the right place, at least for me, and are of remarkable fluidity and precision. There is the manual focus on/off button, very useful for me. To recommend.

Pros: Lightweight, versatile, precise, quiet

Cons: At the moment none

Opinion: Excellent lens that goes perfectly with the concept of mirrorless. Excellent build quality, the rings are smooth and the lens is light but robust. Optical quality is at very high levels on every occasion; the AF is fast and I found no difficulty even with low light. Goal to recommend to everyone, a great all do to always take with you.

Pros: Lightweight, compact, excellent flare seal, sharpness

Cons: I didn't find any

Opinion: I had been waiting for him since February, and i finally got it. Immediately a nice feeling of robustness while maintaining an absolutely acceptable weight. I think that for those like me who have the Sony a7c and therefore look for compactness and lightness without sacrificing quality, it is an almost obligatory choice. I did some first backlight tests and I'm totally satisfied with that. I wait to test it even for night photos, but the premises are very good.

Pros: Lightweight and compact, excellent optical quality

Cons: At the moment I don't know

Opinion: I've had it for a few days but the feeling is very good. Smooth rings with the right clutch. In my gallery I posted a couple of photos with slight post. I would say great in the middle on all the focal points, very good even at the edges. I confirm the somewhat cumbersome lampshed to insert. I had the Tamron 28-75, but that gives me the impression that I'm more incisive. Objective update, I used this lens during the Alba Rally on June 12.13; I have to say that it is a lens that has further convinced me for the overall quality, for the resolve in the photos and above all for the speed of the AF Photographing sports such as cars is always a complicated thing and I have to say that some photos turned out of focus but many came in an exceptional way , so I can only confirm the goodness of this lens In the galleries there are several photos I posted of the event

Pros: Construction quality, compactness, constant f/2.8, smooth manual fire ring, AF-MF button

Cons: Lampshed difficult to insert and remove, autofocus good but not at sony lens level as it suffers with little light

Opinion: The choice to buy a Sony Alpha 7C is naturally aimed at those who want a compact Full Frame. As a result, an attempt is being made to identify good objectives with a pushed but at the same time compact iris opening. It is still almost impossible to satisfy this research but the Sigma 28-70mm with constant f/2.8 goes very close and helps to make my A7c still a beautiful small Full Frame. The Contemporary series is not the Art series so I expect a slightly lower yield but of course it is the price to pay to have a lens that is in the palm of a closed hand. Very very satisfied.
