A zoom-lens reflex (ZLR) camera is a low-end single-lens reflex (SLR) camera having an integrated zoom lens rather than the interchangeable lenses found on other SLR cameras.
The term was coined by Olympus for the IS-series film cameras. [1] Olympus also applied the designation to the D-500L & D-600L in press releases carried by PR Newswire. [2] Olympus now refers to these cameras, along with the D-620L, [3] simply as "Digital cameras". [4] [5]
For the Olympus E-10 and E-20 digital cameras, while some journalists [6] continued to apply the term ZLR, Olympus themselves reverted to using the term SLR. [7] [8]
