You've probably heard about micro four thirds style cameras. There is a lot of anticipation of the Lumix GF1 that will be out soon.
Micro Four Thirds is commonly referred to as a 4/3" type or 4/3 type sensor (inch-based sizing system is derived from now obsolete video camera tubes). It's area is 30–40% less than the APS-C sensors yet is around 9 times larger than the 1/2.5" sensors typically used in compact digital cameras.
Olympus and Panasonic have been promoting this size sensor size. Olympus has their E-P1 body and Panasonic will be coming out with their Lumix GF1 some time this month. Apparently Leica is also coming out with a micro four thirds camera.
I want to put the micro four thirds cameras in perspective for real estate photographers. There is much to like about the micro four thirds style camera systems. Like DSLR quality and compact like weight. What are the key issues for a real estate photographer? As usual it's all about the availability of a wide-angle lens. Here are some facts:
So the bottom line is that while there are some nice weight and size advantages over DSLRs and quality advantages over compacts, there are no cost advantages yet. This could change if micro four thirds is really popular. Prices tend to drop as the number of units sold increase. In the mean time you'll probably have to pay about the same for a micro four thirds system as a ordinary DSLR system.
