Review on π· Exceptional Quality: Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens for Canon Digital SLR Cameras by Hiral Yadav α
A good product at a good price, I advise you to try it.
This lens, obviously, knowingly deserved a high award from EISA in the nomination "European Lens 2022-2022" http://www. Eisa. Eu/awards/history/3/photo. Html I have been choosing a lens to replace the stock Canon EF-S 18-55 IS for a long time. And I couldn't find anything better. If your copy demonstrates front focus or back focus, you can take the lens to a service center, where they will perform a free (during the warranty period) lens alignment. The address of the service center must be viewed in a specific warranty card, because. SIGMA does not have a unified network of service centers in 2022. It is better to call the service in advance and clarify the terms. And at the same time, to clarify whether the adjustment specifically for your camera will be free. In some services, the lens is adjusted for free only for a certain test camera. The adjustment of this lens itself is carried out by its software adjustment (as far as I understand, software adjustment is possible on any SIGMA lenses with an HSM motor). There is nothing wrong with software alignment. At the same time, they do nothing with the camera - they only adjust the lens for it. If your camera has a built-in micro-tuning function, then you can try to get by with this procedure and not contact the service. I really wanted to buy a Canon EF-S 15-85 IS USM, but almost all of these lenses are dismantled - they are removed from Canon EOS7D Kit cameras and sold separately. How to be with a guarantee in this case - the opinions of sellers differ. In addition, reviews about this miracle lens from Canon are mixed. Many people think that it is overpriced. We must also not forget that the lens is, although very important, but only part of the matter. No one has canceled the skills of a photographer yet. For a confident amateur who has already taken his first steps a long time ago, but stopped in thought before the next frontier, this lens at its price will be a reasonable step. And if you want to take the line with the letter "L", then you do not need to read this review. Good luck!
- 1. Convenient range of focal lengths for most situations. 2. Good aperture ratio, although there was an element of craftiness of marketers here. 3. The presence of a stabilizer. 4. A hood is included (Canon, for example, only supplies L-ki with hoods, but not many people can afford their price). And do not think that a hood costs a penny - for a Canon lens, for example, a hood costs about 2 thousand. 5. Japanese assembly (Canon assembles budget lenses in Taiwan) and a two-year warranty. 6. Quality of execution. 7. The main thing. Value for money. According to this indicator, the lens has almost no competitors. And further. I almost forgot. The results of using this lens, as an amateur, not weighed down by extra tens of thousands, are quite satisfactory to me. True, at the same time, I had to deal with the weaknesses of the lens and learn how to smooth them out by choosing shooting parameters.
- 1. The main disadvantage of any SIGMA lens is that it must be carefully chosen for your camera. When buying, you should immediately put the lens on the device and check it for accuracy of focusing. I was only lucky the second time around. The first copy had a light front focus. 2. 72mm filters are expensive compared to 58mm filters for a "kit" lens. 3. Pay attention to the resolution graph of this lens. See, for example, here http://www. Lenstip. Com/223.4-Lens_review-Sigma_17-70_mm_f_2.8-4.0_DC_Macro_OS_HSM_Image_resolution. Html From here you can clearly see where the marketers were cunning, attributing to the lens the ability to shoot with aperture 4.0 at a focal length of 70 mm. With aperture 5.6, the result is much better. You can study the graph, remember its main features and avoid setting shooting parameters that make the image "weak" where it is necessary to have "ringing sharpness".
