The SP-100 is Olympus' top megazoom camera featuring a 50x zoom lens and a unique dot-sight framing assist, so you can spend your time shooting and not trying to find your subject when zoomed in.
The dot sight combines a pop-up piece of glass that has a red sight projected on it. Should your subject leave the frame, just look above the viewfinder eye piece and you'll see crosshairs. Put the crosshairs on your subject and it'll be back in your frame.
The electronic viewfinder's eyepiece extends more than most so you can use it more comfortably without jamming your nose into the camera.
