In 2001 Olympus entered the prosumer digital camera market with a high quality 4MP digital SLR market featuring a fixed 4x optical zoom lens and a true TTL viewfinder which got its image from a beam splitting prism placed between the lens and CCD. That allowed the rear LCD display to show a "live image" from the sensor and with no need to flip a mirror like a traditional SLR, the E10 had an almost silent shutter: ideal for photographing in church.
The fixed lens brought some limitations but Olympus expanded the E10’s versatility with screw-on wide angle and 1.45x telephoto adapters that brought the lens to the equivalent of 200 mm on a 35 mm camera. The other weakness was the base sensitivity of the sensor (ISO 80) and a fair degree of noise when the camera was pushed to higher sensitivities making low-light photography difficult.
I purchased a refurbished model directly from Olympus and it took well over 4,000 images from growing grandchildren to oil and gas construction sites around the world. The images below are representatives from various spots and show the versatility of the camera.
