Drive system
Shutter mechanism
Power supply
Canon has completely re-designed the electrical system to make it
more efcient so that the LP-E6 battery from the EOS 5D Mark II can
be used. To drive the shutter unit, the high performance dual motor
shutter from the EOS 50D has been ne-tuned to extract as much
performance as possible.
A/D conversion
A new Analogue to Digital conversion device has been developed
for the EOS 7D that deals with nothing but the A/D conversion. This
uses 14-bit Analogue to Digital conversion to provide les that have
enhanced colour depth and better colour gradation.
AF microprocessor
In a rst for a non EOS-1 series camera the EOS 7D has a dedicated
AF microprocessor. This speeds up AF processing and allows the
camera to ensure your subjects are sharp while making sure that you
don’t miss capturing the moment.
Shutter system
When shooting at 8fps the mirror has to move very quickly to allow
light through to the sensor for each frame. To counter any mirror
bounce and efciently control the mirror motion, a new mirror
stopper has been developed for the downward part of the mirror’s
motion.
