<b>High-quality wide-angle lens</b>
A 28mm wide-angle prime lens offering an 75° angle of view on full-frame DSLRs. On EOS cameras with APS-C sized sensors it makes a great standard lens, offering the equivalent view to a 45mm lens on a full-frame camera.
<b>Shoot in low-light conditions</b>
A maximum aperture of f/2.8 permits hand-held photography in available light without the use of flash. Image stabilisation allows shutter speeds up to four stops slower than normal to be used without the risk of camera shake.
<b>Fast, quiet autofocus</b>
Canon’s ultrasonic autofocus motor (USM) provides fast, near-silent focusing. Full-time manual-focus override permits fine adjustment without changing focus modes.
<b>Close focusing</b>
Get as near to your subject as 0.23m, and enjoy a dramatic wide-angle perspective.
<b>Space- saving design</b>
Weighing just 260g and measuring 68.4mm x 51.5mm in size, the EF 28mm f/2.8 IS USM is a lens you can take everywhere. Great for travel, landscape and documentary photography.
<b>Designed for great image quality</b>
A seven-bladed circular aperture provides beautiful bokeh, while Super Spectra coatings reduce flare. The EF 28mm f/2.8 IS USM classic prime-lens design minimises distortion and aberrations, which can degrade image quality.
<b>Area of use</b>
Perfect for landscape and travel photography and reportage applications, when a wide-angle field of view enables dramatic close-up shooting.
