I've just bought a D90 last week and have been spending nights reading through the user guide and playing with the camera. There's a lot to take in, but I'm getting there slowly.
Last night, I noticed that the 0's in the shutter speed indicator on the top LCD and rear screen are shown in lowercase. So 1/2000 sec is shown as "2ooo". I can't say whether this was always the case. Is there a reason for this (i.e. some setting I've changed) or is this normal? If it's normal, any reason why they do this?
