It is the successor to the EOS 400D/Digital Rebel XTi. It was announced on 23 January 2008 and released in March 2008 and April 2008 in North America.
For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
The shutter speed dial of a Nikkormat EL Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a ...
Shutter speeds range from 30 seconds to 1/8000 of a second in all exposure modes. A non-timed bulb speed is available. Flash X-sync is available up to a shutter speed of 1/250 of a second. There are 14 custom functions to change the way the camera operates, which set options like exposure steps and mirror lock-up.
Either the flash is firing too late or the shutter speed is too fast (shutter moving vertically). Note the different exposure levels. In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor.

Popular exposure chart type, showing exposure values EV (red lines) as combinations of aperture and shutter speed values. The green lines are sample program lines, by which a digital camera automatically selects both the shutter speed and the aperture for given exposure value (brightness of light), when set to Program mode (P).

A Nikon-style mode dial showing shutter priority mode. Shutter priority (usually denoted as S on the mode dial), also called time value (abbreviated as Tv ), refers to a setting on cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure .
An electronic shutter can compensate for the exposure change caused by a speed ramp without changing the aperture and affecting depth of field. Other types of shutter adjustments, such as an out-of-phase shutter and a fluttering shutter, are also possible. Normally the film is held steady in the gate whenever it is exposed to light.
