I have the standard T5 kit from Amazon. It worked well for a couple of years, but today I took it out and none of the lenses would focus on anything - near, far, close. Grrrrr. I tried different settings, both on the camera and on the lenses, and nothing works! Can this camera be saved? Is it the lenses or the camera?
First off don't panic. In the menus under the Tools tab do a Clear all settings. Fully charge a battery. New SD card. A good one not a cheapo. Go out side on a nice day with the T7 on green square or P mode. Lens switch to AF. Try it.
One word of advice never, never again never buy a camera package from Amazon. With some of the accessory 'lenes' they supply it is possible to damage your Canon lenses beyond repair.
