I bought the Canon 700D recently and I'm really happy with it. Long exposure works just fine but for my purposes and just for experimenting I want to take very long exposures at low ISO for several minutes and see how they turn out.
The minimum shutter speed is 30 seconds and then there is Bulb. But with Bulb I have to press down the shutter button for as long as I want the camera to take the picture. Is there any way to make the camera take a very long exposure in bulb mode without having to hold down the button or do I have to buy a wireless remote?
