• Olympus Evolt E-510
($810, street, with 14-42mm f/3.5-5.6 Zuiko lens)
Sporting a similar Live MOS sensor and compatibility with all Four Thirds system lenses (including Leica zooms, sold separately), the $490-less-expensive E-510 may be the biggest threat to the L10. Its noise reduction and JPEG compression are superior, it has sensor-shake IS that works with all lenses, a higher burst capacity, and a wider variety of compatible glass. However, it lacks the cool, swiveling LCD on the back.
