The EF 500mm f/4L IS II USM Lens from Canon
has all the upgrades needed to make it the go-to super long telephoto
lens for professional photographers and anyone who has the highest
standards for the gear they use.
Using the three mode Optical
Image Stabilization allows you to shoot at shutter speeds 4 stops
slower, and the advanced third IS mode activates only when the shutter
button is fully pressed, so you can pan with fast-moving subjects
without the IS function interfering with composition and framing. An
ultrasonic autofocus motor (USM) enables smooth, fast and quiet
autofocus and a Power Focus mode allows smooth focus change which is
especially important while shooting video. A focus preset function
allows you to store focusing positions and return to them in an instant
when needed. An AF stop button will pause autofocus with just a touch
and manual focus override allows precise manual focus even in AF mode.
sharpness is enhanced with fluorite optics that deliver reduced
chromatic aberration and SWC (Subwavelength Structure Coating) reduces
flare and ghosting. A circular aperture design helps to produce pleasing
out of focus areas.
Dust and water sealing keeps the lens
functioning even in less than ideal conditions and magnesium and
titanium construction elements make it 3 lb lighter than its
predecessor. Flourine coating on the front and rear lens surfaces allows
dirt to be removed easily and an attachment slot is provided for a
wire-type security lock. The EF 500mm f/4L is compatible with Canon's
EF1.4x III and EF2x III extenders and this lens includes a lens hood,
52mm drop-in gelatin filter holder, a detachable tripod collar and a
hard travel case.
