When Olympus released the OM-D E-M1X, there were some complaints that it was too big and heavy for a Micro Four Thirds camera body. Those complaints came from people who appeared to misunderstand the target market for the X. It is aimed at professional wildlife, bird, and sports photographers. I own three X bodies and absolutely love them. The ergonomics are perfect for me and the IQ, processing speed, AF, are all top-notch. Not heavy or too big for me at all.
That said, I do understand the concerns from those who don’t want a larger, heavier camera body. And so does Olympus.
