A Zoom-lens reflex (or 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. Olympus also applied the designation to the D-500L & D-600L in press releases carried by PR Newswire. Olympus now refers to these cameras, along with the D-620L, simply as "Digital cameras".
For the E-10 and E-20 digital cameras, while some journalists continued to apply the term ZLR, Olympus themselves reverted to using the term SLR.
In recent years, some have applied the misnomer ZLR to any camera superficially resembling an SLR whether or not it actually had a reflex mirror, e.g. the Panasonic Lumix DMC-FZ8. (See: Bridge camera)
