I'm new to the world of DSLR shooting. I just got a Canon t5i with a 18-135 IS STM lens.
I've gone into manual mode and played around with the lens on manual focus, and the AF to single shot.
I find it helpful to use the red dot in the viewfinder to tell me when I have achieved focus, but I must half-press the shutter for the focus indicator to work.
My question is, is that an ok thing to do? Will it hurt the camera or lens in any way? And is there a better way to judge focus when manually focusing?
