The big news in cameras is actually pretty small. A new format with the wonky name “micro four thirds” (referring to the image sensor’s size and 4:3 aspect ratio), combines the interchangeable lenses of an SLR with the compact body of a point-and-shoot. The first model, Panasonic’s G1, is about the size of the most petite SLRs but uses even smaller lenses. A design concept from Olympus shows the potential for more-diminutive future models.
In the February issue of Popular Science we take an in-depth look at the Panasonic G1 and put it up against some dedicated DSLRs. The February issue is on sale on the 28th of January.
