December năm trước Canon Đánh Giá Canon Lenses All Reviews NEWER: Canon 55-250mm IS STM. Introduction top Intro Specs Performance Compared Recommendations Adorama pays top dollar for your used gear. B&H Photo lớn - Video - Pro Audio This Canon 55-250milimet IS II is one of Canon"s most popular lenses because it"s super sharp, focuses very cthất bại, has a perfect telephoto zoom range, has Image Stabilization for sharp hand-held photos in dyên light, & is small, light & inexpensive. You can pay more khổng lồ get a lens that works better while being rained-on or blasted in a sandstorm while being beaten around by a news photographer, or that works on expensive sầu full-frame cameras, but even if you pay more for something like a 70-200milimet f/4 L IS, you"ll have sầu a bigger lens lớn carry around, it won"t be any sharper, và it won"t have as broad a zoom range! There are many reasons this 55-250 is ahy vọng Canon"s best selling lenses. This 55-250 requires you lớn move sầu a switch on the lens lớn get from auto to lớn manual focusing; you can"t just grab the focus ring. The reasons you might want khổng lồ pay more than twice as much for another lens with a more limited zoom range are if you shoot a 35milimet or full-frame camera on which this lens won"t work, if you need instant manual focus override (you have lớn move a switch to get to lớn manual focus), or if the plastic lens mount isn"t tough enough for you. Otherwise, this lens is sharp, light inexpensive và works great. This new 55-250mm IS II lens has the same optics as the previous 55-250mm IS lens, with slightly different cosmetics. Compatibility As an EF-s lens, it will only work on Canon"s APS-C cameras. It will not work on 35milimet cameras, it will not work on old 1.3x cameras, & it certainly won"t work on full-frame digital.

Performance top Intro Specs Performance Compared Recommendations OverallAutofocus Bokeh Breathing Color Coma Distortion Ergonomics Falloff Filters Lateral Color Fringes Macro Mechanics Sharpness Stabilization Overall performance top The Canon 55-250mm IS II is optically superb and handles very well for a mostly plastic lens. The biggest negative is that the focus ring & filter thread rotate during autofocus. It"s a kit lens sold with many less expensive Canons, và it"s excellent. There is no reason to pay more for a telephoto lens for a Canon APS-C camera. If you can"t get brilliant, sharp & colorful photos with this lens, you"re doing something wrong. Autofocus performance top Autofocus is fast và quiet, making only a soft motorized sound as it focuses. Video AF is limited by the camera, while regular AF is fast và quiet. Auto/Manual Switching You have to move a switch on the lens, by your thumb. AF Speed AF is fast, as Canons always are. This 55-250 can focus from infinity down lớn 3.6 feet (1.1 meters) in less than a second. AF Accuracy & Consistency I saw no autofocus error on my Canon SL1. Manual Focus You have to move sầu a switch, và then it feels plasticy — because it is. It works fine, but it"s more work & doesn"t feel as nice as lenses that cost five times as much. Bokeh performance top Bokeh, the unique of out-of-focus areas as opposed to lớn the degree of defocus, is usually pretty good. For the softest backgrounds, zoom lớn 250mm, get as cthua kém as possible và shoot at f/5.6. Focus Breathing performance top Focus breathing (the image changing size as focused) is mostly of interest khổng lồ cinematographers who don"t want the image changing kích cỡ ("breathing") as the lens is focused amuốn different subjects. The image from the Canon 55-250mm IS gets bigger as focused more closely. màu sắc Rendition performance top The color balance of this 55-250 seems the same as my other Canon EF lenses. Coma performance top Coma, or saggital coma flare, is when points of light in the corners turn inkhổng lồ batwing-shaped blobs. This is often a problem with fast normal or wide lenses. I see none in this lens; it"s super sharp in the corners wide-open. Distortion performance top The Canon 55-250 II has no visible distortion. For more critical use, use these values in Photoshop"s Lens Distortion tool to remove sầu the distortion. These aren"t facts or specifications, they are the results of my research that requires hours of photography và calculations on the resulting data.
