Pentax's Optio series is just one of the many digicams aiming to make a stab at perceived consumer requirements. Having had a chance to put the Optio E40 though its paces, here are my findings.
Design
The Optio E40 is a compact digicam, or is it? I’d say it's just like any you’ve seen. On the top you’ll find the shutter release and power buttons. On one side is the USB slot and on the other side is the strap holder. It has a 2.4 inch LCD display at the rear and like other digicams the zoom keys on the top followed by a desiccated gallery key and a five-way nav-pad with options.
The Menu and Erase / Green Mode key are located at the bottom of the rear panel. Beneath the camera you’ll find a stand slot, cradle slot and battery compartment (which also houses the SD card).
On the whole it’s not a bad-looking camera. Even with the batteries it’s still quite lightweight and very easy to carry around.
