A photographic lens is used to focus the light onto film or a digital sensor. Many cameras have interchangeable lens systems, allowing the photographer to choose the type of lens to use.
There are many types of lenses, but they generally fall into two main types:
- What do all those cryptic number and letter codes in a lens name mean?
- Where can I find reviews of lenses?
- Is it lenses which make your photographs, not camera bodies?
- How much do lens lineups vary across DSLR platforms?
- How much do lens lineups vary across Mirrorless camera systems?
