For the past few months I've been concentrating on other cameras, both compact and system. Why?
Not because I'm fed up with smartphone cameras, but because I feel they have reached just about their peak - it's hard to buy a high-end smartphone camera with a mediocre camera these days.
Also, I noticed my own shots improved significantly using better glass and larger sensors. I'm witing this post to share my experience with some important factors when upgrading from a smartphone camera. Hope it will help you make up your mind if you're planning to do so yourself.
