Like all other types of batteries, Li-ion batteries will wear down over time, holding less and less charge. Apple says its laptop batteries will reach 80% of their original capacity after âup toâ 1000 full discharge cycles. Other manufacturers commonly rate their batteries 300 to 500 cycles.
A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.
Full frame â High-end DSLRs' and mirrorless cameras' image sensors are the same or nearly the same size as a standard 35mm frame of film, hence the name full-frame sensors. The focal length of lenses on smaller cameras is often translated into full-frame equivalents in order to make comparisons.
