Utdrag: Zoomomfånget ligger perfekt i förlängningen av Canons standardobjektiv på 18–55 mm. Priset är överkomligt, och så har den nya modellen till och med bildstabilisering i fyra steg. Finishen är gjord av plast och fattningen är inte av metall, men mekaniskt är objektivet tillförlitligt. Närgränsen är 1,1 meter och filterdiametern 58 mm. Motljusskyddet ET-60 säljs som extra tillbehör för 145 kronor.
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
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.
