The SP-310 features a 3X (38-114mm in the 35mm format) f/2.8-4.9 all-glass aspherical zoom lens. When the camera is powered down the lens is retracted inside of the body and a builtin shutter closes to protect the lens.

It uses a contrast detection autofocus system with a focus-assist lamp to help illuminate the subject for accurate focusing. The focusing range is:

• Normal AF - (Wide) 7.9" (0.2 m) to infinity
  (Tele) 11.8" (0.3 m) to infinity
• Macro - (Wide) 7.9" (0.2 m) to infinity
  (Tele) 11.8" (0.3 m) to infinity
• Super Macro - 0.8" (2cm) to infinity.

Optional Lenses:  The WC0N-07F Wide Conversion lens decreases the magnification of your subject by 0.7x when your camera lens is set to the wide-angle position. This will help you include more in the picture when shooting skylines, group shots, or houses, just to name a few types of shooting situations.

The TCON-17F Telephoto Converter lens will increase the magnification of your subject by 1.7x when your camera lens is set to the telephoto position. This will help you bring in the subject when you can't get closer, for example, shooting sports or concerts. Both lenses requires the CLA-9 lens adapter.

The built in flash has modes for: Auto, Fill-in, Fill-in & Red-Eye Reduction, Off, Auto & Red-Eye Reduction. The maximum flash range is (Wide) 12.5 ft. (3.8 m), (Tele) 7.2 ft. (2.2 m).

You can frame your pictures with the color LCD or to save precious battery power you can use the optical finder. This is a coupled viewfinder with approx. 80% to 85% coverage. It has no dioptric adjustment. Next to the finder are two LEDs that indicate the flash and focus status.

The SP-310 features a large, wide-view 2.5-inch color LCD that can be used for framing, review and menu operations.

On the top of the "beefy" handgrip is the shutter release with the zoom lens control mounted around it. In playback mode the zoom lever functions as the index and magnified image control. The Mode Dial has positions for: Auto, Program AE, Manual, Aperture priority, Shutter-speed priority, MyMode, Scene (24 scenes total), Movie, and Playback.

Controls on the back: Above the LCD is the Power button, Flash mode (delete in playback) button and the Auto Exposure Lock (DPOF in playback) button. The DISP/GUIDE button turns the color LCD on/off and controls the amount of information displayed on it. The QUICK VIEW button lets you review the last image captured quickly. The 4-way controller lets you navigate menus and select images during playback, the OK/MENU button accepts menu selections and calls up the menu system.
