The Olympus E-410 (or Olympus EVOLT E-410 in North America) is a 10 megapixel digital single-lens reflex (DSLR) camera intended be the smallest and lightest DSLR on the market.

Announced in March 2007 to succeed the E-400 (which was only marketed in Europe), it adds a live preview function and a new "Olympus TruePic III" processing chip that is claimed to provide better performance.

Like the E-400, the E-410 is notable for its small size, omitting the hand grip and exploiting the smaller sensor of the Four Thirds System.

It weighs only 375g and approaches manual focus film SLR sizes, reminiscent of the Olympus OM system.

This newer camera's most notable enhancement over the E-410 is a contrast autofocusing system, for faster shooting in Live View mode.
