Carl Zeiss f2.8/f5.6 Tessar lens. a resolution of 3.2-megapixels, you can take shots suitable for prints up to 5.1 x 6.8 inches (13 x 17cm), however standard 4 x 6 inch photos (10 x 15cm) will turn out less grainy. The N73 supports four image quality settings, from MMS-suitable shots up to the aforementioned print quality photos. Scene modes include auto, macro, portrait, landscape, sports, night and night portrait; the N73 displays a helpful description of each when you're choosing the mode. Red-eye reduction flash mode is onboard, but the N73's LED-based flash is disappointing. Colour tone, exposure, ISO speed and white balance can all be adjusted to pre-defined values for stills.
