Olympus's last 10x Ultra Zoom bridge (2006) — 7.1MP CCD, 38-380mm equiv, RAW, EVF, xD storage, AA power
The Olympus SP-510UZ was a 7.1-megapixel bridge camera introduced in 2006, replacing the SP-500UZ in the Special Performance line and traceable back to the C-2100 Ultra Zoom of 2000. It was the last Olympus ultra-zoom built around a 10x lens — its successor, the SP-550UZ, moved to 18x — and it swapped its predecessor's black finish for silver while lifting resolution from 6 to 7.1 megapixels.
The fixed 6.3-63mm aspherical glass zoom covers a 38-380mm equivalent range, feeding a 1/2.5in CCD with sensitivity from ISO 50 to 4000 (the top two settings at reduced resolution). Shutter speeds run 15s to 1/1000s plus bulb, exposure metering offers iESP multi-pattern, centre-weighted and spot, and the camera captures RAW as well as JPEG. Composition is via electronic viewfinder or 2.5in, 115,000-pixel LCD, storage is xD-Picture Card, QuickTime movies record with sound, and four AA batteries power the 325g Indonesian-built body, which accepts a 55mm accessory tube for filters and converters.
With full manual exposure, RAW capture and a long zoom in a light plastic body, the SP-510UZ suited hobbyists wanting one-camera versatility, and it still works as a cheap entry into CCD bridge cameras for travel and casual wildlife shooting. The small sensor limits low-light work and the EVF is coarse by later standards.
AA power is a genuine used-market plus — no orphaned charger to hunt down — but the xD-Picture Card slot is not: cards are discontinued and expensive, so confirm one is included. Check the EVF and rear LCD both display cleanly, that the long zoom travels its whole range without grinding, and that the pop-up flash releases; also inspect the battery compartment for alkaline leak damage.
