Source-derived summary

The Olympus E-20 (available under the names E-20N and E-20P, depending on whether it had NTSC or PAL video output, respectively) is a 5-megapixel superzoom bridge camera manufactured by Olympus Corporation of Japan, as a successor to its E-10 model. Like the E-10, it has a fixed lens and a beam splitting prism instead of a moving mirror. It has easy dial keys for choices of pictures, videos, and more. It was announced on September 13, 2001.

Editorial analysis

Why this record matters

The phrase “digital camera model” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 22, 2026. The linked authority identifier is Q7089227. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2001.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
