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 17-55mm f/2.8 IS USM Lens Overview
A tremendously flexible standard zoom for APS-C-format DSLRs, the EF-S 17-55mm f/2.8 IS USM from Canon pairs the 27.2-88mm equivalent focal length range with a bright f/2.8 constant maximum aperture. Benefitting this design is a sophisticated optical layout, which includes both Ultra-Low Dispersion glass and aspherical elements to significantly reduce chromatic and spherical aberrations for improved clarity and sharpness throughout the zoom range. A Super Spectra coating has also been applied to individual elements to suppress flare and ghosting for increased contrast when working in bright environments.
