Canon 77D Overview
Comprising a versatile feature-set for both still photography and video recording, the EOS 77D DSLR from Canon blends advanced imaging capabilities with an intuitive design. Revolving around a 24.2MP APS-C CMOS sensor and DIGIC 7 image processor, images can be recorded using a broad native sensitivity range of ISO 100-25600, to suit shooting in a variety of lighting conditions, and a continuous shooting rate of 6 fps benefits working with moving subjects. The sensor’s design also facilitates Dual Pixel CMOS AF, which uses phase-detection autofocus for quick, accurate, and smooth performance to suit both video shooting and stills use in live view. Alternatively, a 45-point all cross-type phase-detect AF system is also featured for shooting stills using the optical pentamirror viewfinder.
Canon EF-S 10-22mm f/3.5-4.5 USM Lens Overview
Covering a versatile wide-angle range, the EF-S 10-22mm f/3.5-4.5 USM is designed for Canon EF-S-mount APS-C DSLRs, and provides a 16-35.2mm equivalent focal length range to suit working in a wide array of shooting conditions. Benefitting the flexible zoom range is a sophisticated optical design, which includes one Super-UD element and three aspherical elements to control chromatic and spherical aberrations, and a Super Spectra coating has been applied to limit flare and ghosting for improved contrast. Additionally, this lens sports a ring-type USM for quick and quiet autofocus performance and full-time manual focus override, and an internal focus design also quickens focusing speeds and maintains the overall lens length during operation.
