Before on a roll you'd see 8 shots whose exposure was not the money perhaps. Then with the detached sensor I'd get 4! Or 3! When i moved to TTL this went down to 2 or 1 or 0. I half expected to see no misses on a contact sheet. I almost never used filters for most of the TTL shots I'd do they were events or wedding or fashion or portrait. But i would aim the flash at the ceiling or behind me or over my shoulder or anywhere in the room which would spontaneously feel like THAT should be the light source. Also you've got a lens shade on your lens the in the camera flash meter is of course taking account of that plus just about every variable you can think of. Lens shade, dirty lens, dirty uv filter, clean uv filter, uncoated uv filter, super coated uv filter, lens with no lens shade, lens with nice lens shade, lens with bad lens shade. UV filter no lens shade. and on and on. A separate sensor introduces plenty of variables which no one needs… often in flash photography you are contending with the readings you are getting because you are shooing into a mirror or something similar to it. A TTL sensor is dealing with what the lens is dealing with. Not what is happening somewhere else. It's a good feeling. You move the f stops by mistake and the flash often will just deal with it when it's TTL. Unless you've just dialed in f22 and aiming at something 25 feet away!
