Just thinking back, I also owned a couple of less well known Canon bodies.
One was an AL-1 which had a 'Quick Focus' feature. Instead of the more usual split microprism type focussing aid in the centre of the viewfinder it had a small rectangular target area. At the bottom of the viewfinder was a display consisting of three LEDs that looked a bit like this:
> ● < If the subject was out of focus in the target area, one of the red arrow LEDs would light - the arrow also indicated which way you had to turn the focussing ring. Once in focus, the green LED in the centre would light up. As I remember, it was pretty useless!
I can't remember the name of the other body, although I'm pretty certain it was from the F series (though sadly not the excellent F1). This body was unusual in that the shutter release was mechanical as opposed to electronic. In other words, even if the battery went dead you could carry on shooting, albeit with no onboard metering. I distincly remember buying this second hand as back-up body for a wedding I did, just in case the unthinkable happened!
Does this Canon body ring any bells with anyone, I'd love to know exactly what model it was.
