The Photosmart M407, also sold as the M407xi, was part of HP's M-series budget compact family from around 2005, sitting below the R-series in HP's consumer camera lineup. It targeted buyers wanting a straightforward, inexpensive digital camera rather than an enthusiast or feature-heavy model.
The M407 has a 4.1-megapixel sensor, SD-card storage, and runs on two AA batteries rather than a proprietary lithium-ion pack, a combination confirmed for this model and shared across several entry-level M-series cameras of the same generation. A small rear LCD handles framing and menu navigation.
Its AA-battery design was the main practical selling point, letting owners replace power almost anywhere without a dedicated charger, at the cost of extra bulk and weight versus rechargeable rivals. Controls stay fully automatic, with no manual exposure adjustment aimed at casual point-and-shoot use.
As a used purchase the M407 is a low-cost, low-resolution entry point into digital photography rather than a camera bought for image quality today. Worth checking are corrosion-free AA battery contacts, a working SD card slot, and that the lens extends and the flash fires correctly on power-up.
