The following opinions have been automatically translated with Microsoft Translator. | Canon EF 70-300mm f/4-5.6 IS USM Pros: Focal range and versatility, stability, overall quality. Cons: Tropicalization, auto focus, rotating front element. Opinion: It 'a lens extremely versatile, compact and lightweight and the quality more than decent. I read the other reviews and I understand that there has to be some variability in quality from specimen to specimen. In my case I have made several comparisons with both the old bianchino 70-200mm L 4 that with the new stabilized and, frankly, I found that being in a bit behind on the whole trip (70-200mm). If the multiplied bianchino returns a slightly higher quality at the expense of a slightly lower LF (280mm vs. 300mm). I also got to try it multiplied with the kenko 1.4X with satisfactory results, especially closing 2/3 stop. Obviously it is not a perfect lens, but considering the cost is really very convenient. The only downside I would say is that the AF speed, which is inadequate for photo hunting of birds or for motor sports. However, it remains more than decent and absolutely valid for other applications. Inconvenient also the rotation of the front element inMAF. All in all it is a great lens as a handyman and it costs a fraction of its homologous noble "L". sent on March 04, 2014 |
 | Canon EF 70-200mm f/4 L IS USM Pros: Sharpness, color rendition, image stabilization, weather sealing, weight Cons: None Opinion: I use this lens for more than three years and I must say I was entranced by its quality! I have changed many lenses, always looking for a better solution, but this can not question it. Its focal length lens makes it an all-rounder: from portrait to landscape, the architectural detail, is lightweight, versatile, color returns simply amazing! The sharpness is fantastic, over the entire zoom range and since the maximum aperture, from the center to the edges. Improves in a bit if you close on 200mm 1/2 stop. rnLente really not to be missed. sent on March 04, 2014 |
 | Canon EF-S 17-55mm f/2.8 IS USM Pros: Excellent quality, fast autofocus, stabilizer, light Cons: Soft edges, made of plastic, not tropicalized. Opinion: I used this lens for almost three years and I think that is a valid replacement for the classic 24-70's full size. Very sharp in the center from the larger aperture, has a certain softness to the edges, which is recovered in a position to close at least one stop, thus losing the benefits of openness. The picture quality, color rendition, sharpness in general, resistance to flare indisputable, but the build quality leaves much to be desired for frankly a lens for almost € 1,000! The stabilizer of the previous generation and then compensates for a maximum of 3 stops, then in reality are about 2.5. I do not agree instead on previous comments in relazne the focal range that I frankly a little "tight". Find it much more interesting than a focal 17-70 or better yet 15-70 even at the cost of slightly lower opening, I think both absolutely technically feasible, without going through a slow "impossible." However, it is definitely a lens to be seriously considered in a kit APS C sent on November 15, 2011 |
 | Canon EF-S 15-85mm f/3.5-5.6 IS USM Pros: Objective handyman, good quality even at full aperture, excellent stabilizer, good build quality, fast autofocus and responsive Cons: It is not sealed, it is not very bright. Opinion: I use this lens now for a good year and I can say that it is fully satisfied. Its versatility is "embarrassing" is not the lever of the car! Fast autofocus, image quality (sharpness, contrast, color rendition, distortion) good. In particular, I have noticed, doing some comparisons with the 17-55 is 2.8 and with the 24-105 4 L is, that the sharpness of the lens is very good both at the center than at the edges, on the contrary of the two objectives of comparison which have excellent sharpness to the image center (greater than that of the 15-85) but a drop of the same closer to the edges. The problem is most pronounced in the 17-55, and can be corrected only by stopping down at least one stop. I also find that the yield is rather constant even with varying different focal lengths. Of course, going beyond 70mm is a certain drop in sharpness. The lens has, in my opinion, a color rendering very pleasant and balanced, basically - like all Canon lenses for the most part - the tone is a bit 'tendency to "cold", but overall pleasant. Also good color saturation, never excessive. Chromatic aberrations are noticed, especially at the edges of the image and in bright light, but I must say that they are not exaggerated, though slightly higher than, for example, than they are on the 24-105 L. I often critical comments on its price, certainly not "cheap", but I think that actually reflect the quality of the lens, much more than in many other cases. A lens definitely recommend to all owners of APS C. sent on November 15, 2011 |
 | Sigma 150mm f/2.8 EX DG HSM Macro Pros: Relatively compact and well balanced with xxD or xD-class machines, optical quality (sharpness, color rendering and focus) Cons: Weight, lack of stabilization, AF slow Opinion: I use this lens for many years and I can say I had a lot of satisfaction. And 'as excellent macro lens, even compared to his older brother (180mm 3.5 EX DG), which I had previously. The colors and sharpness of an image that returns is absolutely fantastic. It 'a beautiful lens for portraits (albeit from a distance) and has the advantage generous opening that allows excellent blurred and ability to work well in low light condioni. sent on November 04, 2011 |
