One of the big drawbacks to using a megazoom camera lens is that moving subjects can move out of frame fast, usually requiring you to retract the lens some to relocate your subject. The SP-100's unique dot-sight keeps you from having to do that.
Built into the frame beneath the pop-up flash is a semitransparent mirror. The dot-sight projects a reticle on to the mirror so you can quickly track and shoot your subject without zooming the lens out and in again.
Shooting modes include: Intelligent Auto (iAUTO), Program Auto (P), Aperture Priority (A), Shutter Priority (S), Manual (M), Super Macro, 17 Scene Modes, 11 Art Filters, and Panorama. Just to the right of the Mode dial is thumb dial for quickly adjusting shutter speeds, apertures, or other important settings.
The lens barrel zoom control lets you change focal length with the left hand while shooting with the right. Olympus also added a focus-limit button so the camera will focus only in a set range when turned on, and focus only in the distance when off.
