I have the timer is not long, but it looks like he is not really suitable for my purpose. I wanted, if I am not at home, for example, make a time-lapse recording from the garden. Thus: beginning at a particular time and end at a particular time. The beginning is not a problem on the start delay. But if I want to do long over 1 hour every 10 seconds a picture now (10s are clouds a good value), then it is probably impossible because I can only set to 99 or an infinite number of individual photographs. Used but would 360 recordings. If you're not on the spot, then it is of course stupid when the camera still carries on for hours nonsensical images, or stops too early. This basic function I would have expected from a Timer. What should I do with but 99 hours. EXPOSURE remains a mystery to me ... But if you're riding for hours near the camera, or just be calculates when to go home, to stop the timer, then it is a useful part. Maybe I'm in the A4 manual overlooked something ... I like to let disabuse.
