If you are looking to step up to a full frame sensor camera but don’t want to spend a lot of money or buy a big bulky camera, you are in luck. Canon just release the lightest and most inexpensive full framed sensor mirrorless camera, the Canon EOS RP. The Canon EOS RP Body sells for less than $1,300 for the body only.

The sensor in the Canon EOS RP is the same as the one in the Canon EOS 6D Mark II Digital SLR Camera Body – Wi-Fi Enabled.

The body is so small that Canon offers a little body extender to add on if you find your pinky slipping off the bottom of the camera.
