Pros
- aperture, excellent stub, good constructive, sharpness.
Cons
- autofocus sometimes misses, many lenses for canon with front and back focus
Pros
- It shoots better than a whale 18-55. Good fast autofocus. Looks solid. Hood and case included.
Cons
- Strong distortion Severely chromate Soapy edges Vignette The stabilizer is not working In the off state, something dangles there and makes noise inside when shaking.
Pros
- Price, decent-solid appearance, strong and solid (as it seemed at first)
Cons
- Below
Pros
- Fast, sharp, HA didn’t notice, doesn’t wash, no misses, heavy (plus for me, fast AF, constant aperture.
Cons
- The lens hood almost does not hold at all, expensive filters
Pros
- Build quality, package. The lens is very sharp
Cons
- Catching hares, faded colors and wadded bokeh
Pros
- Excellent. Juicy and sharp picture, focuses quickly, no worse than Elka 17-40, stub. very good, does not smear! perfectly assembled, complete with lens hood and case, the price is two times lower than the canon counterpart!
Cons
- lenses slightly rattle in the lens! when autofocusing, you often pinch the focus ring with your fingers because of this, it stops and stops focusing, you have to keep your fingers closer to the camera!
Pros
- Price, sharpness at 2.8.
Cons
- The quality of the materials used. Assembly. Chromatitis.
Pros
- Quite working 2.8, constant at all focal lengths.
Cons
- - Traditional "Sigma aftofokus". I bought it mainly for the wide end (because there is a fix of 35), and so, most often there are problems with autofocus at wide angle and infinity (landscapes). Out of 10, 2-3 times he won’t be able to focus at all and 2-3 more times he will say that he has focused, but he will miss a little, and vilely - so that it’s not very noticeable on the camera screen. - The stabilizer often turns out to be harmful: if it is turned on, when there is enough light, it blurs the picture. In addition, when carrying the lens, something rattles inside (apparently, the lenses of the stub). - Pretty bulky.
Pros
- 1. Constant aperture. At 2.8 sharp in the center, from f4.0 and above - the sharpness is already much better. 2. Fast autofocus performance 3. Convenient fr, allow you to shoot from landscape to portrait, while if you take it as the first lens, it will be easier to understand in the future which focal lengths you need. 4. The stabilizer helps a lot in low light conditions 5. A solid picture at the output, although it is a little "warm" 6. From the aesthetic side - the glass on the carcass looks solid and does not seem like a plug, unlike a whale 7. Price / quality: We look at the price of the original 17-55 f2.8 from Canon and compare with the Sigma. There are no comments here.
Cons
- 1. The accuracy of the autofocus out of the box. I strongly recommend testing before buying on a special target. My copy was with a terrible back focus on the short end (judging by the reviews, I don’t have one). I gave it for adjustment under warranty - everything was done in 2 weeks, now the focus hits the target much more accurately. 2. Short travel of the focus ring. In my opinion, because of this, it is quite difficult to accurately focus 3. It is impossible to bring the focus manually until you switch the toggle switch to MF 4. Service, or rather its absence. Officials do alignment only in Hong Kong 5. The lenses inside the lens rumble a little, but these are trifles.
Pros
- - Aperture - Focus speed - good stabilizer - Sharpness (compared to what I used)
Cons
- - Noticeable fragility (as for the "prof. series") - Frequent misses in focus - Aberrations and barrel (distortion) - Focus free - EF-S
Pros
- Fast lens with a working open aperture, sharp from 2.8 to 16. Appearance and build quality.
Cons
- The presence of a large back focus at a wide angle. Small stroke of the focusing ring.
Pros
- aperture, beautiful pattern at 50 mm.
Cons
- in comments
Pros
- Aperture. Stabilizer. Now price Having 550D, I shot more than tens of thousands of photos with this glass (mainly weddings). Processing a good result in lightroom, the customer is satisfied. But.
Cons
- chromate? - yes! vignette? - Yes! misses? - Yes! front focus? - Yes! soapy? - at the edges of the frame up to 4.0 yes!
Pros
- Good fast zoom. At 50mm, interesting bokeh, although not in the trash. The stabilizer is not bad at all
Cons
- very weak trunk - plastic breaks with a small impact. There is no "twisting" focus with autofocus. Moderately works in backlight
Pros
- 1. Working at all focal apertures 2.8. 2. High quality workmanship. 3. Rich equipment. 4. Adequate price for such characteristics. 5. Convenient focal lengths. 6. Looks impressive. 7. Fast autofocus. 8. Quite sharp even wide open. 9. Pleasant bokeh. 10. Made in Japan (not an indicator, but nice). 11. Pretty good stabilizer.
Cons
- 1. A little chromate and vignetting, but not critical. 2. As already mentioned, the focus ring turns easily in manual mode. 3. In the off state, the stabilizer block clanks inside, not a fatal flaw, but annoying from time to time. 4. Specifically, on my lens, the focus periodically smears on different values depending on the focal length. I'm planning on getting it adjusted. 5. On the street, it drains the battery faster than other lenses, there were no such problems in the studio.
