An excellent general purpose zoom telephoto lens
Conventional wisdom holds that the more powerful a telephoto lens you mount on your camera, the more you may need a tripod for shake-free images. With patience and breath control many photographers have long been able take crisp handheld shots with lenses of focal lengths up to 400mm. That ability can now be extended to almost everyone through technology. The best modern DSLRS can produce crisp handheld images with short exposures at high ISO settings and, coupled with good image stabilization lenses, can effectively expand the focal length (or power, if you will) of lenses that can be used to advantage without a monopod or tripod.Still, it remains the case that a great percentage of the distant images that most amateur or enthusiast photographers will want to capture can be taken with telephoto lenses that do not exceed 400mm. In that case, any lens that covers all or most of the range between 100mm and 400mm is a reasonable candidate to add to your photography kit. If you feel an unmet need to take frame-filling moonrises behind a ghostly oak tree on a remote ridge, you can get a dedicated 1000mm lens later on.For a general purpose telephoto lens, this 70-300mm zoom can’t be beat. In my experience the optics have produced crisp images at any focal length and at most aperture settings, though images taken with apertures at the middle of its range (f/11, for example) appear just slightly sharper than ones taken with a wide open lens.Canon has thoughtfully included two different image stabilization modes for the benefit of individuals who use the lens in different ways. Mode 1 is for general purpose image stabilization when the camera is held still to capture a stationary field of view. Mode 2 is used for panning shots in which the photographer is following an item or individual in motion. This mode locks out attempts to correct for blur in the direction of camera motion. And you can of course lock out IS altogether if you are so inclined. Autofocus can also be locked out in case you are shooting nearby objects from a tripod and want to pick the exact focal point of the image field yourself. The word “macro” is printed on the lens, but that strikes me as a little aspirational. I would consider this lens a close-focusing zoom, as you can get fairly close-up images of smaller objects that are a little distance away. Minimum focusing distance is just under five feet, and at that distance the 300mm setting will let you fill the frame with an object about five inches wide. This could be a good lens to capture images of large winged insects and even hummingbirds, as those interesting subjects are notoriously intolerant of close approach by photographers. For true macro photography of flower details or smaller insects, you should mount a different lens.At the other end of its zoom range, focal length in the 70-135 range is excellent for portrait photography or casual snapshots that isolate individuals or groups of two or three in large gatherings.Build quality is excellent, options for use are rich, optical performance is excellent and the lens, though not tiny or light, is compact and manageable. Canon makes other, more expensive lenses with similar design features that might better satisfy the most critical photographers, but in light of the relatively low cost of this lens and its great flexibility, this has to be one of the best general purpose lenses that Canon manufactures.Recommended.

Sehr gute Verarbeitung und für den Preis Abbildeleistung. Stabi funktioniert sehr gut

I purchased this lens for travel photography and used it most recently in Chicago to capture street scenes and architectural images (not to mention three Chicago Cubs baseball games). It functioned perfectly with my Canon EOS 7D and Canon EOS Rebel SL1, in both automatic and manual modes and produced beautiful, crisp images. This lens is a bit different from my others in that it takes just a fraction of a second longer to focus in automatic mode. Zoom first, lightly touch the shutter release to focus (you can hear the motor as it focuses), then shoot. The whole process is virtually instantaneous and I never missed a shot. This lens locks in the retracted position for travel. Greatest thing since sliced bread. Looking forward to using it in Iceland.

Es un excelente lente especialmente si viajas, es versatil, rápido y un buen complemeto para amateurs o profesionales que requieren fotografiar a largas distancias,
