We recommend Canon EOS cameras, specifically the ones listed on our supported cameras page.

The Canon EOS cameras have a large live view with exposure simulation.
They also have smooth mechanics during capture.

Get the Canon EOS R or 5D Mark IV if you have a larger budget. If you want a full-frame camera at a lower price, look at the Canon EOS 6D.

The Nikon Z series also works really well with Dragonframe.

If you have a limited budget, you can look for used Digital Rebels (or 450D/1000D) on Amazon.
