What is the difference in performance between rechargeable and non-rechargeable batteries?d
Rechargeable batteries perform a little differently than non-rechargeable batteries. The voltage coming from an Alkaline (non-rechargeable) battery decreases steadily as the battery is discharged. Ni-MH and Li-Ion batteries have a lower starting voltage than Alkaline (typically 1.2-1.3V vs. 1.5V for Alkaline), but rechargeables maintain this level until they are almost discharged. One potential problem: the battery life indicator of the camera may be calibrated for alkaline batteries, which coul ...
What are SLR digital cameras?
In an SLR (Single Lens Reflex) camera, the user is seeing exactly what the camera is seeing through a series of prisms and mirrors. This becomes important for more advanced photographers. In SLR cameras, it is also possible to interchange lenses and keep the lenses from other cameras. Many digital SLR cameras also offer higher resolution since they are aimed at the pros. The disadvantages of SLR digital cameras are the significantly higher costs, bigger size and weight, and a small delay before ...
