Josh Ginter on deciding to go with micro four-thirds:
In complete contrast, Micro Four Thirds cameras don’t deliver the same image quality and they are certainly held back technically by their 2x cropped sensors. I don’t think there’s any denying that Micro Four Thirds cameras are not capable of doing the best portraiture.
That entire paragraph isn’t quite correct. The sensors are very good and really only have trouble with huge prints. Beyond that they are on par with most other sensors. This is a long debated topic, but I’m in the camp that the sensor size doesn’t matter.
What’s different between micro four thirds and say Fujifilm is that the latter has different color rendering and the best noise control I’ve ever seen. Different sensors and sensor sizes really only give you different looks in your photography. It’s up to you to decide which look you like.
