So, having a hard time finding an answer online. I just picked up the RP for a deal I could not pass up. It is one of the original kits that included the 24-105 non L and the adapter. Still at original firmware. I got to the hotel were staying at, put my 50mm 1.8 on it with adapter and its going crazy trying to focus anywhere I move it. I put the RF 15-35mm 2.8L on it and it does the same thing, constantly trying to focus. I did reset all camera settings as it was a display model I think. It still is always trying to find focus when I move the camera. Im coming from a 7D and 77D that neither tried to focus until the shutter was half way pressed. Is there something I need to change in settings or is this a mirrorless handicap?
