Olympus's 2010 entry waterproof compact — 12MP CCD, 28-102mm zoom, sealed to 3m, aka mju/Stylus Tough 3000
Launched in January 2010, the Tough 3000 was the entry model in Olympus's waterproof Tough family, sold in Europe as the mju TOUGH-3000 and in North America as the Stylus Tough 3000. It preceded the TG-numbered models already common on the used market.
Built around a 12-megapixel 1/2.3in CCD, it pairs a 3.6x internal zoom equivalent to 28-102mm with sensor-shift image stabilisation, a 2.7in anti-glare LCD, 720p HD movie recording and HDMI output. The body is waterproof to 3m, shockproof from 1.5m and freezeproof to -10C. Around 1GB of internal memory backs up the SD/SDHC card slot, and the LI-42B lithium-ion battery is rated near 160 shots.
It suits beach, pool, ski and travel duty where a phone or ordinary compact is at risk; image quality is ordinary small-sensor CCD fare, but the sealed, lens-inside design has no protruding parts to damage and shrugs off sand and knocks.
On used examples the waterproof seals are the story: inspect the battery/card door gasket for perished rubber and the body for signs of past flooding (corrosion, fogged lens) — treat untested seals as compromised and re-test shallow first. LI-42B batteries remain easy to source, and SD storage is no obstacle.
