Zoom range (mm)
View more details.
Refers to the level of zoom built into the lens. It's measured in millimeters (mm), because it refers to the physical distance between your camera's sensor and the point of convergence on the lens. The numbers, e.g. 24-70mm, indicate the maximum width and zoom available. This column only refers to optical zoom, which is lens components physically moving to increase or decrease magnification, like a telescope.

Sensor type
View more details.
The sensor converts light to a digital image. Different sensors have different effects on the picture as it's processed (e.g. colour, tone, hue, saturation). Though there are different brands and models, some competing camera manufacturers use the same sensors.

ISO rating
View more details.
ISO relates to the camera's sensitivity to light. The higher the ISO, the greater the sensitivity, and the less light required to produce a well-lit image in dark environments. However, high ISOs have more image noise (grain) and less accurate colours. Noise reduction tech in newer cameras can negate some of these problems.
- 200 - 25600
-
Exposure correction (lower)
View more details.
Used to automatically alter photos beyond the exposure suggestion of the camera to make them brighter or darker. Often called exposure compensation. Measured in EV units, 1 EV equals one exposure stop (or steps). Negative range shows the number of stops the camera can go below the recommended exposure. Adjustment range in stops.
