Adapters are available for a wide range of camera media, parts and accessories. Examples:
- A lens adapter is a device to mount lenses made for some type of camera on another camera for which they were not originally designed. See the main article on lens adapters.
- The most common film adapter is the rollfilm back for plate cameras. Plate adapters were attachable to some early 20th century rollfim cameras. 35mm film adapters were available for a few medium format cameras.
Memory card adapter
- Micro SD cards are often sold together with an adapter for using them in Secure Digital card slots. Similar adapters for micro SD in XD-Picture Card slots are also available.
- The simplest tripod adapter connects camera and tripod if they have different thread sizes.
- Modern cameras which usually use their own system flash can use old flashes (e.g. with excessively high trigger voltages) with help of an adapter.
- Common battery types used in cameras and flashes are LR44, 625, AA, AAA, CR2 and CR123. Some older battery types are no longer available. Some of these lost battery types can be replaced by common batteries in adapters.
- This kind of adapter replaces a microscops ocular, and adapts a camera body. If an SLR or a CSC is adapted, then the camera's viewfinder serves as alternate ocular.
