Pentax Optio E85 — AA-battery budget digital compact from Pentax's entry-level E-series, 2009.
The Pentax Optio E85 belongs to Pentax's E-series, a line of low-cost point-and-shoot digital cameras from the late 2000s aimed at first-time buyers rather than enthusiasts. Positioned below the company's premium Optio ranges, it launched in 2009 as a value-priced snapshot camera.
It carries a small 1/2.3-inch CCD sensor of around 10 megapixels, a 3x optical zoom lens, and a 2.7-inch LCD, closely matching the specification of the sibling Optio E80 from the same generation. Images save to SD/SDHC cards, and power comes from two replaceable AA batteries rather than a lithium pack.
Handling is entirely automatic, with no manual exposure controls, reflecting its role as a simple point-and-shoot rather than a creative tool. The AA-battery design favoured affordability and worldwide battery availability over the compactness of lithium-powered rivals.
On the used market the Optio E85 trades for very little, often bundled with other job-lot compacts. Buyers should check the AA battery compartment for corrosion, confirm the zoom lens extends and retracts without grinding, and test the LCD for dead pixels before purchase.
