Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens.

Brand: Canon Model: 6473A003 Number of items: 1 Dimensions: 4.00" h x 4.00" w x 7.00" l, 1.00 pounds 75-300mm telephoto zoom lens with f/4-5.6 maximum aperture for Canon SLR cameras Improved mechanism makes zooming smoother; front part of zoom ring sports silver ring Measures 2.8 inches in diameter and 4.8 inches long; weighs 16.8 ounces; 1-year warranty 4.9-foot closest focusing distance; 32- to 8-degree diagonal angle of view

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.

If you have a digital SLR and use satisfied with the kit lens (18-55), these may be the ideal next step for you. In particular, to increase your zoom reach the point where you shoot birds A) B in the moderately distant trees) to be able, on the other side of the valley a bit and for the interest zoom. These are just two examples. One is you do not able to this effectively with this objective but is to take pictures of sports. How so? Consider some of the following vulnerabilities: * A 300mm zoom range of the higher opening is limited to 5.6 (you have to use very slow shutter speed for fast action snap shots, remember the inverse relationship between the aperture and shutter speed.) *) The size of the combination target weight, it is difficult to sustain when connected to a camera like the Rebel XT * autofocus slow and often inaccurate (I do not understand why Canon did a version of this USM $ 20 more, but did not never in the triple rebate program) * Chromatic aberration is important in high-contrast lighting, such as direct sunlight (if you do not know what it means for the chromatic aberration online search word or see my review of the Canon 28 28 mm on Amazon, but to summarize, it would be a discoloration on the edges of objects in the image) This kind of weakness that limit the ability to use it in all sorts of other situations or circumstances. As a general rule to follow, if the lighting is not ideal, this goal will give you a hard time. Meaning, you can use it, but you can get an excessive number of blurred images due to the slow shutter speed earthquake. As for what the lighting conditions are ideal? That would be in full sun with little or no clouds and light baths are subject / object in front or side of this lens is so bad? Not really, as with many other lens when the lens is coupled with a good camera yet out performs most of the point and shoot cameras. In addition, the results in line or slightly below the kit lens (18-55). So if you're happy with your kit lens, which provides an equivalent 3X zoom zoom (55/18 = 3), why not a different lens, that its scope will expand by another 4X zoom (300/75 = 4) to add? Nothing wrong with expanding your horizons! PS. Two more points about the use of LENS: First, if you can trust this lens at slow shutter speeds (I know I can not), then the low aperture should not be a big problem. Second, if you look at high ISO shooting (more like 400 or 800), maximum rate should be reopened no problem. The good thing about photography is that you are afraid to do a thing in so many ways, so do not be to explore with this lens! 320 of 349 people found the following review helpful low-class lens from Sergiy Beketov I have the Canon 75-300mm lens for almost a year and have looked at it from the inside out. Unfortunately I can not admit that there is a good lens.First all friends, it's not USM (Ultrasonic Motor), and while incorporating AF motor, it is very slow anyway. And as telephoto lenses are generally for recording high-speed events (such as sports, running animals, etc.) makes the low speed, focus not good.Secondly, its light-factor is quite low (4.0 to 75mm and 300mm for just 5, 6), forcing either high-speed film (ISO 400 to not less than), or in the bright light shoot (which is not possible every time you shoot to use). And last but not less important. I'm not good in mechanics, but I know that Canon 75-300mm lens to 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.
