Capture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 75-300mm telephoto zoom lens. The optical system, construction, and exterior are the same as the EF 75-300 mm f/4-5.6 III USM’s. The difference is that it uses a DC motor instead of a USM to drive the AF. As with all Canon lens, this 75-300 model carries a one-year warranty. Focal length: 75-300mm Maximum aperture: 1:4-5.6 Lens construction: 13 elements in 9 groups Diagonal angle of view: 32 (at 11 feet) to 8 degrees (at 15 feet) Closest focusing distance: 4.9 feet Zoom system: Rotating type Filter size: 58mm Dimensions: 2.8 inches in diameter, 4.8 inches long Weight: 16.8 ounces The most affordable of Canon’s long telephoto zooms, this lens is excellent for subjects from portraits to wildlife and nature. It shares the same 13-element optical system as the 75-300mm USM lens, but uses a DC motor for autofocus. Close-focusing down to 4.9 feet (1.5m) allows filling the frame (at 300mm) with a subject the size of a dollar bill, and it’s compatible with the Canon 58mm Close-up lens 500D for even more spectacular shots of small objects. Isolate the Interesting Part The eye tends to see the whole rather than the individual parts. It also sees what’s near and not what’s far. By bringing attention to those things missed by the eye, you can create many interesting pictures. It could be the grimace of an athlete, the grill of a classic car, or a girl against a blurred background. Telephoto lenses can also compress images to give dramatic effects. You are limited only by your imagination.
Most useful reviews 702 of 712 people found the following review helpful. The lens is as bad as some people say it is? By Abdul Rahman Aljabri No, it is not, especially if you take into account the intended users. If you have a digital SLR and use with the kit lens (18-55) are satisfied, the purchase of this lens be the perfect next step for you. In practice, increase your zoom reach the point where A) B in the form of photo removed birds trees) could, on the other side of the valley and hit some of your interest zoom. These are just two examples. One thing you will not actually in a position with this lens, but is the sport to take pictures with. How so? Consider some of the following vulnerabilities: * 300 mm zoom range of the maximum opening is limited to 5.6 (you have to grab a very slow shutter speed using fast action shots, remember the inverse relationship between aperture and shutter speed.) ) * The size of the lens set weight makes it difficult to keep stable when connected to a camera like the Rebel XT * slow and often inaccurate autofocus (I do not understand why Canon makes a version of this aim for $ USM 20 more, but never included in the discount program triple) * is significant chromatic aberration in high contrast lighting, and full sun (if you do not know what I mean aberration term search online or check out my review of the Canon 28 mm 28 on Amazon, but to summarize, it would be a discoloration on the edges of objects in the picture) This kind of weakness will limit your ability to use this lens on all types of situations or circumstances. As a rule of thumb to follow if the light is not ideal that goal will give you a hard time. In this sense, can be used, but may have blurred images because it has changed very slow shutter speed. As for what the lighting conditions are ideal? This would be in full sun with little or no clouds and with the bath of light to the subject / object in front or side is so bad that purpose? Not really, like many other goals, when the lens is coupled with a good camera makes it even more digital point and shoot. It also provides results on par or slightly below the kit lens (18-55). So if you're happy with your kit lens, which offers a zoom range comparable with 3X zoom (55/18 = 3), why not add another goal that will extend your range of 4X zoom with another (300 / 75 = 4)? Nothing wrong with broadening your horizons! PS. TWO MORE ON use of this objective: first, if you are sure you can handle this objective with long exposure times (I know I can not), then the opening to the bottom should not be a big problem. Second, if you shoot fine at high sensitivity (closer to 400 or 800) and again the low aperture should not be a problem. The good thing about photography is that you can do one thing in many ways, so do not be afraid to explore this goal! 320 of 349 people found this review useful lens by Sergiy Beketov lower class, 75-300mm lens Canon for almost a year, considered backward. Unfortunately I can not admit that this is a lens.First good of all, you do not have USM (Ultrasonic Motor) and also built from the AF motor, which is very slow anyway. And because the lenses in general, to capture fast events (such as sports, running, animals, etc), not low approach speed is not good.Secondly, is light-factor is very low (4.0 to 75 mm and only 5.6 per 300 mm) that forces you to use high speed film (not less than 400 ISO) or to shoot in bright light (it is not possible every time you fire). And last but not least. I'm not good at mechanics, but I know for sure is that the 75-300mm lens Canon produce blurred images. Whether you use a tripod or not, the images are still very fuzzy, which is very bad for the image will be enlarged to 300mmAnyway, I recommend you buy.
