Pentax Optio M40


The Pentax Optio M40 comes with an affordable price of $200; it has little, though, to distinguish itself from other 3X-zoom, 8-megapixel point-and-shoot cameras (but perhaps we're getting a bit jaded). Its compact metal body feels solid and reliable....

Solid metal body ; Programmable shortcut button on the back

Poor image results with flash ; A bit dated looking compared to others

Not the jazziest-looking camera, the M40 earned its chart spot with a sturdy body and a low price. Flash shots looked drab.

Optio M40


Introduced in July 2007, the 8-megapixel Pentax Optio M40 is one of a number of 3x optical zoom cameras on the market for less than $200. Its most touted features are digital shake reduction and face priority autofocus and auto exposure. Read on to see...

Thin, lightweight, and portable design ; Effective flash over long distances ; Low noise levels through ISO 800 ; Good dynamic range at low ISO sensitivities ; Well organized, customizable photo software ; Affordable price

Loud zoom lens with barrel distortion and limited aperture ; No zoom in Movie mode ; No optical/mechanical image stabilization ; Lens blurs the edges and corners of the frame ; Overpowering flash at short distances ; Terrible noise and low dynamic...

Pentax Optio M40


The compact Optio M series exterior has been redesigned for 2007. Powered by an ultra-thin Lithium-Ion battery and featuring a miniaturized circuit board, the M40 body is a slim 0.7 inches (18mm). While the aluminum alloy body offers ruggedness as well...

The Optio M40 features a Digital Shake Reduction mode to adjust the camera sensitivity to as high as ISO 3200 to match the brightness of the subject. Even in low-light conditions, this feature increases shutter speeds to help reduce blurring and...

Pentax Optio M40 Digital Camera - Express Review - The Imaging Resource!


Can a digital camera be cute and sophisticated at the same time? The Pentax Optio M40 certainly feels that way. Thin and sleek, with only a few controls, the Optio M40 isn't much larger than a Blackberry. It's the perfect companion for busy consumers...

Tiny size, very pocketable ; Large selection of preset shooting modes ; Good overall color ; Large 2.5-inch LCD monitor ; Face Recognition AF mode useful ; Digital Shake Reduction mode helps reduce blur in low lighting ; Excellent prefocus shutter lag...

High chromatic aberration lens distortion in the corners ; Strong blurring in the corners from lens ; Higher than average image noise, even at the lower ISO settings ; Anti-noise processing trades away subtle subject detail at all ISO levels ;...

Exposure remains under automatic control, though there are still a fair amount of creative options available to the user, such as white balance, ISO, exposure compensation, etc. Though the camera offers the standard 3x optical zoom, Pentax extended the...

Pentax Optio M40


The Pentax Optio M40 joins the dense market of sub-$200 digital cameras. The 8-megapixel Optio M40 carries the standard specifications that characterize this popular category: a 2.5-inch LCD screen and 3x optical zoom lens. The camera boasts high ISO...

The camera touts a high 3200 ISO sensitivity setting with Pentax's Digital Shake Reduction system, offering more low light flexibility than the Casio Exilim EX-Z77, with an 800 ISO maximum, or the GE G1, with a maximum 1600 ISO. Pictures taken with the...

Pentax Optio M40 Review


The Pentax Optio M40 is a newly-introduced "ultra-slim, sophisticated metallic body" point & shoot (P&S) that is a refresh of the Optio M30 – the new camera gets a few more pixels on a slightly larger sensor, a higher resolution monitor, stronger...

Accurate color rendition ; Good shutter lag time once focus is acquired

Monitor hard to use in bright conditions ; Poor dim light focus acquisition time

Pentax includes a wrist strap, Li-ion battery and charger, USB and A/V cables, CD-ROM software and operating manual with each camera. The camera accepts SD or SDHC memory cards
