The new S5 (it seems that Canon skipped an S4 model) seems to be a similar camera but with more megapixels, better image stabilization, and many exciting new features.
The new compact inherits optical Image Stabilizer (IS) technology, professional-grade optics and extensive movie functions while introducing a host of new features designed to increase the photographer’s success rate. Powered by Canon’s DIGIC III image processor, Face Detection Technology improves focus, exposure and flash output for people shots while the new Red-Eye Correction feature effectively solves red-eye problems in captured photos. An increased sensitivity range of ISO 80-1600 complements the optical IS system for extended low light performance.
Other key advancements include a larger, higher resolution 2.5” vari-angle LCD, additional shooting modes and extended video recording. The compact design incorporates a new hot shoe that provides compatibility with selected Canon EX Speedlite external flashes, adding to an accessory list that includes Wide, Tele and Close-up converter lenses.
