look, i'm not a pro photographer, though ive been a pretty active 'snapper' for thirty plus years, but i just dont understand why anyone needs or even wants to shoot at 1.2. i just do not get it at all. the reason most photographers spend big bucks on great digi cams is to allow use of higher shutter speeds in low light, and so assumedly allowing one to NOT have to shoot wide open.
now i do understand that 'art', or very specific physical circumstances, may dictate use of 1.2, but again, these are a narrow set of circumstances.
for the vast majority--make that vast vast vast majority--of photographers, please tell me what so floats your boat about 1.2, or even 1.4? help educate me!
