Lens Mount
The mechanical and electronic interface that couples a lens to a camera body.
Optics, Lenses & FiltersMacro Lens
A lens corrected for close focusing that reproduces a subject at life size or larger on the sensor.
Genres, Movements & TheoryMacro Photography
Photography at magnifications approaching or exceeding life size, revealing detail invisible to the unaided eye.
Lighting & FlashModelling Light
A continuous lamp built into a flash head that previews where the shadows will fall.
Optics, Lenses & FiltersNeutral Density Filter
A grey filter that reduces the amount of light entering the lens uniformly across all wavelengths, without altering colour.
Sensors & Digital CapturePixel Pitch
The centre-to-centre distance between adjacent photosites on a sensor.
Focus & Depth of FieldPlane of Focus
The flat surface, parallel to the sensor, at which the subject is rendered with maximum sharpness.
Optics, Lenses & FiltersPrime Lens
A lens with a single fixed focal length that cannot be zoomed.
Motion, Video & Creative TechniquesPrism Refraction
Holding a prism, glass or crystal in front of the lens to bend light and introduce reflections, flares and repeated fragments.
Focus & Depth of FieldShallow Depth of Field
A narrow zone of sharpness that isolates the subject against a strongly blurred foreground and background.
Motion, Video & Creative TechniquesShaped Bokeh
Rendering out-of-focus highlights as a chosen shape by placing a cut-out mask over the lens.
Sensors & Digital CaptureShot Noise
The unavoidable randomness in the arrival of photons, which produces grain even from a perfect sensor.
Optics, Lenses & FiltersTeleconverter
A supplementary optic mounted between lens and body that multiplies focal length at the cost of light and, usually, sharpness.
Optics, Lenses & FiltersTilt-shift Lens
A lens that can be tilted or shifted relative to the sensor, controlling the plane of focus and correcting converging verticals.
Optics, Lenses & FiltersZoom Lens
A lens whose focal length can be varied continuously across a range while holding focus.
Exposure & MeteringStop
The fundamental unit of exposure change: one stop doubles or halves the amount of light reaching the sensor.
