Can you use different brand DSLR cameras when filming a movie>?

I'm curious on lets say I'm making a short film, and I'm hiring camera operators 1.) Uses the newest Canon with its lenses 2.) Nikon with Prime lens and 3. A sony, or Black Magic. If you have different brands such as that shooting one scene, and shots so you can cover more angles will that affect the overall quality of the film, when it comes to post Production.

Or does it not matter long as you adjust the settings?

You can, just jeep in mind: These cameras will all have slightly different looks to them. The transitions can be a bit jarring if you don't correct for this. They might record in different formats, they ll probably have different White balances, (whether you set them manually or use auto, they can be a bit off) the sharpness and dynamic range can be different as well. Most of these differences can be reduced with color correction and other adjustments in you video editor.
