Pentax's 2002 metal compact — 3.2MP CCD, 3x 37-111mm zoom, CompactFlash storage, D-LI2 battery
The Pentax Optio 330RS was announced in mid-2002 alongside the 4-megapixel Optio 430RS, updating the original metal-bodied Optio 330 with improved processing. It sat in the middle of the early Optio range and is a distinct model from both the Optio 330 and the budget 330GS that followed.
It has an effective 3.2-megapixel 1/1.8-inch CCD with a primary-colour filter, producing images up to 2048x1536 pixels, behind a 3x SMC Pentax zoom equivalent to 37-111mm. The 1.6-inch, 80k-pixel LCD supplements an optical finder, and 11MB of internal memory backs up CompactFlash card storage. Five program modes include video and multiple exposure, and power comes from a D-LI2 rechargeable lithium-ion battery rated for roughly 120 shots. The compact metal body measures 92x59x31mm.
As an early-2000s enthusiast compact the 330RS now appeals mostly to collectors of first-generation Optios and shooters chasing early-CCD colour rendering. It remains a capable daylight snapshot camera with a decent lens, but the small dim screen, modest battery life and leisurely operation date it more than its later siblings.
It stores to CompactFlash, so factor in a card and reader — still obtainable but no longer stocked everywhere. The D-LI2 battery and its charger are the other essentials to confirm, as tired packs sap the already modest shot count. Check the lens extends promptly, the LCD is free of bright columns, and the tripod bush and door catches on the aging metal body are undamaged.
