Nearly all of the external controls and buttons on the EOS 50D are the same as those found
on the EOS 40D, with two exceptions. The main control dial now includes only two camera
user settings—one was deleted to make room for the Creative Auto activation setting. Also,
the playback Jump button was removed below the LCD to make way for a Func. Button.
Microphone
The back of the EOS 5D Mark II has undergone a fairly extensive button overhaul from the
EOS 5D, and a remote control sensor and microphone were added to the camera front.
On the back of the EOS 5D Mark II, several buttons have been added or moved to facilitate
Live View Function and HD video recording modes. In addition, the right thumb can easily
reach the new AF-ON button, and the Live View mode activation/print button sits comfortably
to the left of the viewfinder. From the top, the button arrangement is nearly identical the
preceeding models; with the EOS 5D Mark II, the top buttons have been re-arranged so
that the most frequently-used functions are closer to the shutter button.
The shutter mechanism on the EOS 50D remains unchanged from the EOS 40D, providing a
rated life up to 100,000 shots and shutter speeds from 30 sec. to 1/8000 sec., with a maximum
X-sync for flash at 1/250 sec. The shutter mechanism on the EOS 5D Mark II is newly
designed, with an integrated shutter-cocking unit and an
extended rating up to 150,000 shots. It also features shutter speeds
from 30 sec. to 1/8000 sec., with a maximum X-sync for flash
at 1/200 sec. Two separate motors, one dedicated to driving
the mirror, and one to cocking the shutter, power the entire
drive system. This two-motor system enables Live View shooting
and video shooting as well. With the EOS 5D Mark II, wireless
