Pros
- I don’t want to repeat myself, a lot has been written, HE is really EXCELLENT, especially on a full-frame camera.
Cons
- No at all, but if you find fault, I would like to have a "stub" on it.
Pros
- This lens has quite a few advantages, but I will briefly dwell on the main ones: 1 Really working f / 4, Autofocus is tenacious, does not crawl and aims exactly at the target + Color reproduction is better than the EF-S 10-22, which I once used on the Canon 600 Filters 77 The build quality is at its best, Reasonable price.
Cons
- There are no shortcomings, a good lens for sane money, but there will certainly be those who will compare with 18-55 and demand aperture ratio of almost 1.0, while forgetting why 17-40 is needed at all and under what illumination it is necessary to take photos.
Pros
- Compact, not very heavy, UNKILLABLE (fell several times) allows you to shoot from a very close distance, which is nice - the need for a macro lens has turned into a "desired need"
Cons
- Sometimes lathers, at 60 where you have to turn up the sensitivity, you want, of course, 2.8, but taking such a lens on 60 sometimes you want stronger cups :) Chromatic aberrations are visible at 17mm, sometimes very noticeable - http://500
Pros
- - not heavy - the trunk does not leave - excellent run-up, especially on FF - sharp enough - Quiet, fast, tenacious autofocus
Cons
- I didn' a pity the aperture is not 2,8))))
Pros
- 1 Very good sharpness throughout the field in the range of 20-40 including with backlight, juicy color reproduction, an adequate level of geometric and chromatic aberrations, which practically disappear from a 20 for example, at 17 mm focal length, focusing to infinity significantly reduces distortion compared to focusing on close objects, although not completely, Moisture and dustproof design, especially if you wind the protective filter, A full-featured USM ring drive provides very fast, quiet and accurate autofocus and continuous manual override (FTM) Almost round diaphragm with 8 A very nice price compared to competitors for such a convenient lens.
Cons
- 1 to 20 (approximately) MP Canon 5D, MP, you should not rest so much on this shortcoming, it does not affect most frames so much, and from 25 / 21 or at least a Canon EF 16-35mm f / 4L IS USM for completely different money, and the same more expensive Canon EF 16-35mm f / 2.8 The presence at a focal length of 17 to 25 mm (approximately) A hood and a soft case are included, but they are of little use, I do not use them.
Pros
- - a crimson stripe - a sign of protection - cheap, if used, despite its lightness and visual quality
Cons
- For a complete frame, it's probably fine, but the cost of a new one is quite pricey. - I'm not sure what enables modern dense corp matrices.
Pros
- This lens has already received an adequate amount of praise; there is not much more that can be written about it. Both the letter L and the red stripe make their point abundantly clear. The sharpness of the lens, the build quality, and the inclusion of a case round out this package. For a very long time, not even a single speck of dust or a scratch could be found on the surface after being subjected to the elements, such as rain and the impact of falling from a height of growth. Naturally, it is only used after going through the filter. There was not even a single lack of focus. Even when it was pitch black. I am ecstatic with how well the zoom ratio turned out. Does not change size when zooming.
Cons
- To achieve the desired results with the Canon 50D, a few adjustments were necessary. It is not particularly sharp between apertures 4 and 5.6, but it is sharper than any EF-S. Only with 15-85 can it be compared, and even then, the second range serves somewhat different objectives. My aperture is almost always closed to 8-11 because the range involves use either for landscapes or indoors (of course with a flash), and in this state it is very sharp. The range involves use either for landscapes or indoors. When you need a portrait - at the long end and with the aperture wide open - then ringing sharpness is not necessarily required, and light software is even suitable for the portrait. When shooting macro with a built-in flash (if such perverts exist), there is a problem that arises: due to the size of the lens, it casts a shadow on the lower part of the frame that covers more than half of it. This can be problematic. If this may be considered a downside, then removing the cover once the hood has been screwed on is a pain in the neck =) This issue can be remedied by using a wound filter.
Pros
- It completely retains backlight, the color reproduction and contrast are good, and the focusing is both quick and accurate. The quality of the materials and the assembly are of the highest standard.
Cons
- At 40, it's little soapy and heavy.
