At first, I thought it was EL-100, not EI-100... Well, that's beside the topic here. The Pentax EI-100 is a superb camera for its money. I don't remember the exact price but I believe it to be very cheap. Since I am just a beginner in photography, I...

The only problem that I've encountered is the battery problem - the EI-100 eats batteries rather quickly. My sugggestion: get rechargables

This camera was an dissapointment. The picture quality was very poor and unaceptable for normal family and holiday pictures. USB driver dosnt work propably. So I did return the camera to the shop, got my money back - and baught a Canon Power Shot A40...

The USB driver in the camera mostly dosnt wake the camera up when it gets connected on camera side, and the USB driver on the PC chrashes the entire computer on very regulary basis

Product Specifications

The EI-100 combines all the familiar and comfortable features of a conventional point and shoot camera with the power and advantages of filmless digital technology. Its 1.31 megapixel CCD allows you to capture crisp, clear images to view immediately or save for later. It's the perfect entry-level camera for those looking to go digital. The 1.31 megapixel CCD is perfect for capturing images to e-mail to friends and family, or for making prints up to 5x7 inches in size. The EI-100 captures quality images with its 5.5mm lens (equivalent to 42mm in 35mm format). The digital zoom function offers 2X shooting. As easy to operate as a conventional compact camera, the EI-100 incorporates convenient auto features and selectable modes that enable excellent results in almost any shooting condition. A built-in self-timer delays the shutter release by 10 seconds, allowing the photographer to join family or friends for memorable pictures. The EI-100 assists in low-light shooting conditions with a built-in flash that offers automatic discharge, flash-on, and flash-off modes. A red-eye reduction mode is also provided with a single pre-emission discharge. The easy-to-view 1.8-inch LCD monitor allows you to quickly review your pictures. Simple controls provide quick playback of stored images by frame (with 4X magnification), slide show or thumbnail format. The built-in 8MB of memory is capable of storing up to 17 images at the highest quality resolution. The EI-100 is compatible with USB and CompactFlash for connectivity and added convenience. The camera provides the ability to transfer images from the internal memory to a CompactFlash card for removable storage. Its five white balance modes (Auto, Daylight, Shade, Tungsten Light and Fluorescent Light) provide the creative means to express light in its intended colors. The EI-100 uses four easy-to-find AA batteries.
