It is very nice. Realistically unless your doing long exposures or are looking to use a specific aperture its the way to go, especially in those times when you really don’t have time to dick around. Still allows you to control white balance, color saturation, sharpness, ISO settings etc unlike the Auto side of the dial (Auto/Portriate/Sports/Landscape etc)
Sometime in low light its not the greatest, as it will choose a slower shutter speed then you really need. Auto ISO adjustment is really nice as well, keeps my camera at ISO 100 unless light is low enough to where you would need a shutter speed of 1/15 and start bumping it up automatically. This feature is great, though in manual can sometimes select an ISO you don’t want based on the sutter aperature you want even if light allows for it. I usually shoot a little underexposed which using anything auto tries to fight :lol
