I shoot with several different camera brands, models, and types. My general advice would be to invest more money in lenses compared to camera bodies. Camera equipment is obviously an important facet of photography, and I make sure to always have a wide range of camera lenses to be prepared for any type of subject. If I had to narrow it down to 3 lenses, I would stick to a 16-35mm wide angle lens, a 24-70mm for portraits, and a telephoto such as a 70-200mm.
