I grew up with manual only cameras, then graduated to Av and M, and now I just cannot get my head around the need to use Tv to keep my shutter speed up. I set the aperture, and the camera just jacks the shutter speed up to the maximum at that aperture, based on where I am pointing it and/or a cloud going by, or whatever.
In broad day light, that's what I do. Mostly I use Av mode. Only when I want to go creative or use a manual flash I use M mode.
But in an indoors arena, where I need to use the flash, Av changes the shutter speed according to the focal length. So, with my 28-70 f/2.8 lens, I'm not going to see anything higher than 1/90s. I hope you understand what i mean.
