REVIEW: Canon EF-S 55-250mm f/4-5.6 IS STM Lens Review
12 februari 2014
Utdrag: Handling and Features Performance Verdict Specification This telephoto zoom lens provides an angle of view equivalent to an 88-400mm used on a 35mm camera. This version is an update to the previous Canon 55-250mm IS II lens, adding Canon's new stepping motor technology, which promises smoother, quieter autofocus performance, which is especially suited to recording video.

Fördelar: Great sharpness in the centre throughout the zoom range, Lightweight, Fast focusing, Effective stabiliser
Nackdelar: Plastic lens mount may put some buyers off this lens, Quite expensive compared to its predecessor
Utdrag: Features and handling The unusual 55-250mm focal length range of this telephoto lens butts up neatly with Canon’s 18-55mm standard kit lens. Between them, the two optics offer EOS users an uninterrupted range of 18-250mm – that’s 29-400mm once you factor in the EOS system 1.6x crop factor. (This is an EF-S lens, so it shouldn’t be used on D-SLRs with full frame or APS-H sized sensors.
Utdrag: An 88-400mm equivalent, this is Canon's longest EF-S (digital only) zoom, and roughly the low-cost digital alternative to its 100-400mm f/4.5-5.6L full-frame "white" image-stabilized zoom that's so hot with pros. At $280, street, this 55-250mm is by far Canon's most favorably priced IS tele zoom, with the only glass close to it a 70-300mm IS lens that streets for roughly $550.
Utdrag: The EF-S 55-250IS is a relatively new lens designed to supplement the EF-S 18-55IS "Kit Lens" for the Digital Rebel line of DSLRs. Like the EF-S 18-55/3.5-5.6 IS, the 55-250/4-5.6 IS uses Canon's new low cost IS system. Nevertheless, Canon claims up to 4 stops of additional stability, which is as good as (or even better than) lenses with Canon's traditional IS control. Canon suggests that sharp images can be obtained at shutter speeds as low as 1/15s.
Utdrag: The Canon EF-S 55-250mm f/4-5.6 IS STM Lens is an inexpensive, light, entry level telephoto zoom lens that has image stabilization, very good image quality for the price and a very useful focal length range that will nicely complement most general purpose zoom lenses . It is a Canon "EF-S" lens, so the 55-250 IS STM lens is only compatible with APS-C format Canon EOS DSLR cameras including at this time the ultra-popular Rebel/***D/****D, **D (70D, 60D, 50D) and 7D...
Slutsats: When writing the summary of this particular lens we can easily say that we get what we paid for. After spending less than 300 USD we can get a lens with a good resolution at the whole focal length range, with well controlled chromatic aberration and optical stabilization – maybe not being 4EV, but still relatively effective.
Nackdelar: slight focal plane tilt which results in small, however measurable, differences in chromatic aberration and resolution levels between the two sides of the frame, noticeable astigmatism, relatively large vignetting for all focal lengths, too much plastic in its body
