The EF17-40mm f/4L USM is a lightweight ultra wide angle Canon EF zoom lens.
Ultra wide lens for analogue EOS SLR camerasThe EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users.
Standard zoom lens for digital EOS SLR cameras
While it is an excellent lens when used with an analogue SLR camera, the EF17-40mm f/4L USM is especially well suited for digital SLR cameras with an imaging sensor size smaller than the 35mm format. Indeed on such digital SLR cameras these focal lengths can give an angle of view approximately equivalent to that of a 28-70mm lens used on a 35mm camera, which makes it the ideal standard zoom lens.
Superior optical performance
The EF17-40mm f/4L USM has 12 lens elements arranged in 9 groups. Super Spectra Coating on the elements ensures excellent colour balance and minimises ghosting and flare. To provide superb image quality over a 17-40mm zoom range the lens uses three aspheric elements of two different types, while Super UD (Ultra-low Dispersion) glass is used to prevent the chromatic aberrations that often can degrade the subject edge clarity.
Extensive set of high-end features
Minimum focusing distance is just 28mm throughout the entire zoom range.
The Auto-focus works silently and quickly thanks to a fast central processing unit with an improved AF algorithm. You can override AF mode with manual focus should you wish.
Controlled by an electromagnetic diaphragm, the EF17-40mm f/4L USM's circular aperture can achieve a more attractive appearance to out of focus background areas in a picture.
The front of the lens does not rotate as you focus. This means, for example, that polarising filters still function effectively as you zoom in and out. At the rear of the lens there's a drop-in gelatin filter holder.
Highly resistant to moisture and dust, the EF17-40mm f/4L USM is ideally suited for use in harsh environments. Environment friendly lead-free glass is used throughout its construction.

MINUS:
Detta objektiv gillar jag skarpt. det känns väldigt gediget i handen och det väger inte så mycket heller. Skärpan kan jag inte klaga på och snabbheten är otrolig.
Liknande produkter: sigma EX serien i samma brännvidd.
Köpt hos: Inwarehouse
Pris: 9250
MINUS: Egentligen ingenting
Kostar en slant men är ändå prisvärd. Grymt skarp, ljudlös och snabb AF, håller antagligen för det mesta då den är väldigt gedigen.
Har även funderat på 16-35/2,8 men den är för dyr (för min plånbok i alla fall)
Liknande produkter: Canon 16-35, Tokina 19-35, Sigma 15-30
Köpt hos: Cyberphoto
MINUS: 77mm filtergänga = dyra filter.
Bra kvalitet och känsla för pengarna. Hade naturligtvis varit roligare med f.2,8 men då hade väl objektivet blivit både tyngre och dyrare. Ett väldigt trevligt och prisvärt normalobjektiv för DSLR.
Liknande produkter: EF 17-35/2,8L och EF 16-35/2,8L USM
Köpt hos: Privat
MINUS: Inga än så länge.
Liknande produkter: Canons betydligt dyrare 16-35 objektiv
Köpt hos: Cyberphoto
Pris: 10000
