Yesterday I was trying to take pictures with Canon R7 + RFS 18-150 STM lens and found that auto focus struggles at different zoom levels. It works fine when there is no zoom ( 18 mm ) or full zoom ( 150 mm ) but struggles to focus when i use any focal length in between for the same subject. This is around noon so there is plenty of light and it's in in A+ mode.
When i press the shutter button it basically hangs sometimes before focusing or doesn't even respond sometimes. Is this a mechanical issue or a software issue. Camera and lens are almost brand new.
Camera Firmware version: 1.4.0
Lens Firmware version: 1.0.0
It seems to be fine now after I did a factory reset but I am not sure why it happened and if it would again in the future .
Solved! Go to Solution.

The AF mode in [A+] mode is the hybrid between One Shot and Servo. So it takes a little longer to focus because the camera has to first figure out which AF mode to use. This is why there is typically an automatic mode customized specifically for basic sports photography.
