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.
The sensors used in current DSLRs (Full-frame which is the same size as 35 mm film (135 film, image format 24Ã36 mm), APS-C sized, which is approximately 22Ã15 mm, and Four Thirds System) are typically much larger than the sensors found in other types of digital cameras.
