Since DSLRs and mirrorless cameras will require you to invest in lenses (again, not cheap) consider what you already have access to to decide on a brand. If you happen to know someone who has a decent collection of Canon or Nikon DSLR lenses you can borrow, or if you got a tip on where to go for good second-hand lenses from a certain brand, go with a DSLR from the same manufacturer. If you want a more modern design, go with a mirrorless camera from Sony, Olympus, or Fujifilm. Whichever platform and brand you commit to, know these two factors will be crucial in any future camera choices. I started shooting with a Canon DSLR and have been doing so for almost a decade now. Changing systems is just too costly for, at best, minor benefits.
