Take a look on Ebay and get yourself a used MB-23 Multi-Control back, I highly recommend it. Just unclip the standard back door and clip this one on.
As Nuno Souto says, it will do the date in between frames etc etc, but most importantly for shooting transparency it will BRACKET AUTOMATICALLY.
From the instruction manual let me spell out its main functions:
1/ Data Imprint Function (choose from many combinations of date/time/hour/frame/exposure in etc etc etc)
2/ Auto Exposure Bracketing (Up to 19 continuous frames, each with a different exposure. Center value is selectable.)
3/ Freeze Focus Function (shutter will fire automatically when a subject enters/moves into preset focus position)
4/ Interval Timer Function (Lets you take specified number of shots at specified intervals for a something something something)
5/ Exposure Delay Function (Lets you set remaining time before exposure and number of shots)
6/ Long Time Exposure Function (Lets you set exposure duration up to 999 in hours minutes or seconds)
7/ Daily Alarm, Film Alarm and Film Stop Functions
8/ Shutter speed/aperture and frame count indication
9/ Imprint Level Adjustment
I also stand by the MB-20 grip to make it a short wheel base F4.
