Canon EF 17-40mm f/4 L USM Lens

Canon EF 17-40mm f/4 L USM Lens in Bangladesh The Canon EF 17-40mm f/4 L USM Lens features a wide-angle range, constant f/4 maximum aperture, and a robust design. Three aspherical elements and one Super UD element are present, which eliminate chromatic and spherical aberrations to achieve great sharpness, clarity, and color accuracy. Additionally, a Super Spectra coating has been used to reduce flare and ghosting for better contrast in challenging lighting settings. This wide-angle zoom’s internal focusing mechanism and ring-type USM complement its image capabilities and allow for quick, silent, and accurate autofocus performance as well as full-time manual focus override. This lens is additionally weather-sealed for usage in challenging environmental circumstances. Although intended for use with full-frame Canon EF-mount DSLRs, wide-angle zoom can also be used with APS-C cameras, offering a 27.2-64mm equivalent focal length range. Consistent lighting is maintained throughout the zoom range thanks to a constant f/4 maximum aperture. For great clarity and color fidelity, one Super Ultra-Low Dispersion glass element significantly lowers color fringing and chromatic aberrations. For better sharpness and accurate depiction, three aspherical components significantly reduce spherical aberrations and distortions. For increased contrast and color neutrality when working in harsh lighting circumstances, Super Spectra coating has been given to specific parts to reduce ghosting and flare. In order to provide both full-time manual focus override and fast, accurate, and silent autofocus performance, a ring-type Ultrasonic Motor (USM) is used in conjunction with an internal focusing system. A seven-blade diaphragm with rounded edges creates a beautiful out-of-focus effect that is advantageous when using selective focus and shallow depth of field techniques. The prestigious L-series includes this lens, which is protected against moisture and dust for use in harsh outdoor conditions. This lens contains a rear filter holder for up to three cut gel filters in addition to the front 77mm filter ring.
