Rent NowThe Canon EF 1635mm f/4L IS USM is a professional L-series wide-angle zoom lens designed for full-frame EF-mount DSLRs, offering a versatile focal range ideal for landscapes, architecture, interiors, and travel photography. Its constant f/4 aperture provides consistent exposure throughout the zoom range, while maintaining a more compact and lightweight design compared to faster ultra-wide alternatives.
Optically, the lens incorporates two ultra-low dispersion elements to reduce chromatic aberrations and color fringing, along with three aspherical elements that help control distortion and spherical aberrations for improved sharpness and edge-to-edge clarity. Canon’s Super Spectra coating is applied to minimize flare and ghosting, resulting in better contrast and more accurate color reproduction in challenging lighting conditions.
A built-in Image Stabilizer provides up to four stops of shake correction, improving handheld usability in low-light environments or when using slower shutter speeds. Autofocus is handled by a ring-type USM motor paired with an internal focusing system, delivering fast, accurate, and near-silent operation with full-time manual focus override when needed.
As expected from Canon’s L-series lineup, the lens features robust weather sealing for protection against dust and moisture, along with a fluorine coating on the front and rear elements to resist smudging and make cleaning easier. A rounded nine-blade diaphragm helps produce smooth, natural background blur when working with selective focus.
This lens is designed for full-frame cameras but can also be used on APS-C bodies, where it provides an equivalent focal range of approximately 25.656mm.
