It has been a very busy week for us here at Photography Life with so many new products announced and launched by several major camera and lens manufacturers. The marathon of announcement articles is coming to an end and the last (hopefully) camera that we need to mention is the new m4/3 sensor mirrorless Panasonic Lumix GM1. But, by all means, it is not the least interesting product to come out this week. In fact, the GM1 is rather special. Let me start by saying this – it is tiny.
1) A Few Thoughts on (Micro) Four-Thirds System
Before Olympus mirrorless took entry-level DSLR market by storm, the 4/3 format didn’t really make all that much sense. With a sensor smaller than APS-C, it was distinctly amateurish. Image quality just wasn’t there, either, and the 4:3 aspect ratio, while a classic, was only shared by compact cameras. However, Olympus insisted on putting such a small sensor into rather large DSLR camera bodies, such as the Olympus E-5. A sensor four times smaller than full-frame in a comparable body? Four-thirds was always supposed to be minuscule – win in size where it lost in performance. That was the only real advantage it could exploit and for a long time Olympus made the mistake of trying to keep its DSLR system alive (which, incidentally, had a very loyal group of users). I still remember how they promised four-thirds would continue to exist when they introduced the E-5 in 2010. Make no mistake. Olympus DSLRs are done for. The only way they are going to “live on” is “spiritually” through micro four-thirds system and cameras like O-MD E-M1 that can use original four-thirds Zuiko lenses effectively.
