Pentax's slim 2007 compact — 7.1MP CCD, 38-114mm equiv zoom, 2.5in screen, Digital SR high-ISO mode.
The Pentax Optio M30 was announced in January 2007 as a slim, budget-friendly member of the Optio compact family, sitting alongside the T30 and W30 in that year's line-up. It packed then-fashionable high-ISO shake reduction marketing into an 18mm-thin body aimed at everyday snapshooters.
It carries a 7.1-effective-megapixel CCD behind an smc Pentax 3x optical zoom equivalent to 38-114mm, with a 2.5-inch, 115,000-pixel LCD and no optical viewfinder. Sensitivity runs from ISO 64 to 400 in auto, extendable to ISO 1600 manually and ISO 3200 in the Digital SR mode, which raises ISO rather than stabilising optically. Maximum stills are 3072 x 2304, and power comes from the proprietary D-LI63 lithium-ion battery.
As a late CCD-era compact it works for casual shooters and digicam collectors chasing mid-2000s colour rendering. Period reviews criticised heavy barrel distortion at the wide end of the lens, so architectural lines suffer, and the high-ISO modes trade a lot of quality for speed. In good light it remains a competent pocket camera.
Used buyers should budget for the D-LI63 battery ecosystem: cells and USB chargers are cheap third-party items but confirm what is included. Check the screen, the camera's only framing tool, for scratches and bright-spot damage, verify the lens extends without error, and expect dust ingress on examples carried loose in pockets for years.
