It's very important to choose a camera that feels comfortable in your hands. Although most DSLRs are similar in size and build, mirrorless cameras are more varied in design. Some resemble SLRs, with an electronic viewfinder in the center of the body behind the lens mount. Others put the EVF in the corner, similar to the position of an optical finder in a rangefinder camera, and typically offer a smaller handgrip. You can even get one with an optical viewfinder if you don't mind spending big bucks on a Fuji X-Pro or Leica M rangefinder. Generally, an SLR-style mirrorless camera is a better fit for larger lenses. The central viewfinder and sizable handgrip make balancing a big lens a bit more pleasant. Rangefinder-style cameras are a better option if you expect to use smaller zooms or prime lenses. Think about controls, too. If you are interested in capturing fast action and working with big lenses, look for a camera that has a joystick control on the rear panel—it comes in handy for interfacing with the autofocus system. Other models, including many from Fujifilm and Nikon's retro Z fc, include discrete dials to set shutter speed, a plus for photographers who want to try their hand at manual exposure. The camera you choose should be the one that you are most comfortable using. If a DSLR is too big or small for you to hold comfortably, or if the controls are not laid out in a way that makes sense to you, chances are you won't enjoy using it as much as you should.
