- bursting dust Chromatism not smooth zoom
- Fast focusing, beautiful picture, decent stabilizer, convenient controls, reliable. He has been with me in very humid places (tropical rain in Thailand, .), and in cold ones (outside the Arctic Circle) and nothing happened to him.
- Quite dark, too large range of focal lengths (more than 3 times), a little soapy at the extreme values of focal lengths and at a fully open aperture.
- 1) Range of focal lengths. 2) Constructive - convenient rings for adjusting the focal length and focus. 3) The ability to manually fine-tune the focus after autofocus. 4) 17-24mm barrel distortion that can be used as a beautiful artistic effect.
- 1) Small f-number, especially at the long end. 2) Not very effective image stabilizer. 3) Chromatic aberrations at 17-24mm. 4) Barrel distortion at 17-24 mm, which does not allow shooting architecture very well.
- Optics : center resolution, acceptable astigmatism, coma Mechanics: stabilizer working and very quiet: 2-3 stops, USM ring - focus adjustment without switching, Internal focusing - polarizer without problems Price, weight and size for 5x zoom,
- Optics : 17mm in the furnace : barrel, aberration, vignette, distortion, edge resolution 17-40mm Mechanics: the lens block falls out over time under its own weight and there is no retainer (but put on a tight rubber ring under the zoom ring of the lens and smile) Dust, but how much it will depend on the photographer
- Decent appearance
- Dark Strong optical distortion Unsharp
- - Convenient FR range - Price - Ultrasonic motor, fast focusing - Stabilizer - Internal focusing, i. E. the front lens does not rotate - relevant for those who shoot with a polarizer or a gradient filter - Ability to manually focus at any time
- - drop-down trunk - luminosity - sharpness is not amazing :)
- 1. Image quality for its price. I mean 9 thousand, not 19.5 that they want for him now. For 19.5 it is simply not needed. 2. Stabilizer. 3. Convenient focal lengths. 4. Fast and accurate autofocus 5. Sharpness, compared even with 17-40L. On an open hole, of course, do not expect it, but starting from 5, everything looks very good. 6. Nice appearance compared to other kits and other cheap lenses. With a hood, it's absolutely gorgeous.
- 1. Weak constructive. Over time, the zoom ring begins to play. The aperture cable is frayed and the lens comes out of storage. The harness itself is cheap (200-250). To replace it, you need to disassemble the entire lens. In the service, repairs will cost from 2500 and more. Backlash and the above jamb can happen even after a year of use. 2. Long trunk vacuum cleaner. 3. Barrel distortion at wide end 17-24, but not fatal. It is edited in editors, and often it is a feature in general. 4. Chromatitis, 18-55 for example does not suffer from this, which is very strange. 5. Price at the moment. Not that it is a minus, but simply puts an end to the purchase of this lens.
- this lens has no advantages
- all the disadvantages are inherent in lenses, terrible geometry at 17mm no sharpness Ha
- no matter how they slander this lens, I can say that it is a good investment for beginners and progressive photographers. Sharp enough, good autofocus, + stabilizer.
- Of course, two things come to mind at once. Aperture and trunk. Aperture really does not give the advantage of photographing in rooms with dim light. The trunk leaves itself after long-term use.
