The way I see it, cameras and lenses are the tools that allow me to turn my vision into compelling prints. They must be able to do so while staying out of the way of my creativity and being priced within my budget. So far, the M43 system is giving me the best balance of IQ, portability, features, cost and fun. Its ergonomic qualities and very effective image stabilization let me leave my tripods at home most of the time. Together with the other higher-end Olympus and Panasonic M43 bodies, the E-M5 II is a masterpiece of electronics and electro-mechanical miniaturization without sacrificing its handling. There is a bounty of features and well placed external controls. The camera is weatherized and can handle everything I through at it. While I strongly admire the E-M1 II, I currently consider it over-engineered for my use and do not intend to purchase it, reserving my money for upgrading my lenses.
The very high quality Olympus 12-40mm f/2.8 and 40-150mm f/2.8 lenses are my workhorses. With the MC-14 teleconverter, it's an equivalent zoom range of 24 to 420mm f/4. I purchased the two minuscule but good Panasonic slower lenses for when I need maximum portability but I find that I use them very little. Working with the two f/2.8 Pro lenses is extremely satisfying. Like any other introduction of a new technology, there has been resistance to the acceptance of the M43 system. Its evolution and growing sales figures (also among professionals) notwithstanding, there are still people calling this gear a bunch of toys, maliciously and not. Working for a day with the setup mentioned above without preconceptions would certainly change their mind. Most of the pictures on this website were taken with 4/3 and M43 gear (most of the others with Pentax APS-C).
