Ну в доках пишут что : When shutter speeds of 1.3 seconds or slower are used, images are processed to reduce noise after being taken. A certain amount of processing time may be needed before you can take the next shot.
You should set [IS Mode] to [Off] when lowering the shutter speed and shooting with a tripod (p. 168).
When shutter speeds of 1.3 seconds or slower are used, the ISO speed is fixed to ISO100

Я больше о том что надо IS mode выключать.
А то оно может слабые звезды за шум считать и замазывать.
