This enables the use of lenses that are best suited for a given photographic need, and allows for the attachment of specialized lenses. Film SLR cameras have existed since the late 1950s, and over the years, a very large number of different lenses have been produced, both by camera manufacturers (who typically only make lenses intended for their own camera bodies) and by third-party optics companies who may make lenses for several different camera lines.\u003c\/p\u003e\n\u003cp\u003eDSLRs became affordable around the mid-1990s, and have become extremely popular in recent years.\u003csup class=\"noprint Inline-Template\"\u003e[\u003ci\u003e\u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Wikipedia:Manual_of_Style\/Dates_and_numbers#Chronological_items\" title=\"Wikipedia:Manual of Style\/Dates and numbers\"\u003e\u003cspan title=\"The time period mentioned near this tag is ambiguous.
