This Canon 55-250mm IS II is one of Canon"s most popular lenses because it"s super sharp, focuses very close, has a perfect telephokhổng lồ zoom range, has Image Stabilization for sharp hand-held photos in dyên light, và is small, light và inexpensive sầu.

You can pay more to 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 lượt thích a 70-200milimet f/4 L IS, you"ll have a bigger lens to carry around, it won"t be any sharper, và it won"t have sầu as broad a zoom range! There are many reasons this 55-250 is amuốn Canon"s best selling lenses.

This 55-250 requires you khổng lồ move sầu a switch on the lens to get from auto khổng lồ manual focusing; you can"t just grab the focus ring.

The reasons you might want lớn pay more than twice as much for another lens with a more limited zoom range are if you shoot a 35mm or full-frame camera on which this lens won"t work, if you need instant manual focus override (you have sầu lớn move a switch lớn get lớn manual focus), or if the plastic lens mount isn"t tough enough for you. Otherwise, this lens is sharp, light inexpensive & works great.

This new 55-250milimet IS II lens has the same optics as the previous 55-250milimet 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, and it certainly won"t work on full-frame digital.

Versions

The original version is recognized by its silver-colored focal length scale.

This newest version is marked "II" and is all blaông chồng, with a silver trlặng ring, as shown in this review.

Overall performance top

The Canon 55-250mm IS II is optically superb và 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, and it"s excellent. There is no reason khổng lồ pay more for a telephoto lens for a Canon APS-C camera.

If you can"t get brilliant, sharp và 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 & quiet.

Auto/Manual Switching

You have khổng lồ move sầu 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 khổng lồ 3.6 feet (1.1 meters) in less than a second.

AF Accuracy and Consistency

I saw no autofocus error on my Canon SL1.

Manual Focus

You have to move a switch, và then it feels plasticy — because it is. It works fine, but it"s more work và doesn"t feel as nice as lenses that cost five times as much.

Bokeh performance top

Bokeh, the chất lượng of out-of-focus areas as opposed to the degree of defocus, is usually pretty good.

For the sofkiểm tra backgrounds, zoom lớn 250milimet, get as cthua kém as possible & shoot at f/5.6.

Focus Breathing performance top

Focus breathing (the image changing kích cỡ as focused) is mostly of interest khổng lồ cinematographers who don"t want the image changing size ("breathing") as the lens is focused amuốn different subjects.

The image from the Canon 55-250mm IS gets bigger as focused more closely.

Color 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 inlớn 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 lớn 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.
