I think John brought up an excellent point, mainly, that AF SEEMS to have its share of shortcomings when used for railfanning. Sure, roster shooters can use it with no problem, but John brought up several real-life action situations where AF falls flat on its face.
Believe me, I WANT (and need) it to work, as my vision keeps getting worse every year. But I really don't see how it ever CAN work, so long as it expects the focus point to be centered (at least vertically) in the viewfinder. I rarely compose a shot that way. Maybe Canon should arrange the 5 AF points as an 'X', with two at the top intersections of thirds, one at dead center, and two at the bottom intersection of thirds. Wait, I should patent that idea. :) As for the AF being driven crazy by headlights, what's a guy to do? The head-on super-tele seems like the BEST application of AF, as you want to track the nose of the loco as it gets closer. We need a techie from Canon to tell us exactly how the hell we're supposed to use AF for OUR applications. I know Nikon really couldn't care less :( Jim Gilley [EMAIL PROTECTED] http://www.eesoft.com/rr --> SPORRS: Serious Photographers of Railroad Related Subjects
