Yes, because of dirt issues you pretty much need at least two camera
bodies. Best to switch lenses as little as possible.
We used to need as many bodies as different types of film. Now we
need as many as different lenses.
Older Canon bodies are very reasonably priced on eBay if you're
careful. I've been buying them there for 4 years, now. Most users
do not need the top of the line, or the most recent model. Noise is
nearly non-existant on the entire line of Canon and Nikon SLR type
digitals up to 400 ISO at this point and the multiplier factor is a
great boon as you get to the longer lenses.
