The RF 15-35mm f/2.8L IS USM from Canon is also characterized by its bright f/2.8 constant maximum aperture. This bright design enables working in available light conditions and also affords greater control over the depth of field. The range of wide focal lengths suits working in a variety of situations, from landscape to documentary shooting, and this zoom is complemented by an advanced optical design that greatly reduces color fringing and distortion for high clarity and sharpness. An Image Stabilizer also compensates for up to five stops of camera shake to help produce sharper handheld shots in difficult lighting conditions. A unique Control Ring is also integrated into the lens design for intuitive control over exposure settings from the lens itself. Additionally, this 15-35mm is weather-sealed and has a fluorine coating to protect the front and rear elements. Constant f/2.8 maximum aperture maintains consistent illumination throughout the zoom range and suits working in available light conditions. Three aspherical elements are used to correct spherical aberrations and distortion for improved sharpness and accurate rendering. An Optical Image Stabilizer helps to minimize the appearance of camera shake by five stops to better enable working in low-light conditions and with slower shutter speeds. A protective fluorine coating has been applied to the front and rear element to resist fingerprints and smudges and to make cleaning these elements significantly easier.
