Eric Kim on Street Photography and Gear Obsession
Find a camera that you are comfortable with and responds well. It is good to experiment to see which camera fits your shooting style, but once you find a camera that works reasonably well (80% of your expectation) and stick with it. Changing cameras, lenses, and gear is an unhealthy habit that has no end.
Found this great blog post today that dovetails nicely with what I often write (and recently wrote) about.
