Why on earth would the vast majority of Rebel owners want AFMA ?
Are they going to be shooting with 200 Ls at f2 ?
AFMA is extremely tricky to use properly and easy to b*****k up your AF.
It's not that tricky to use. Just aiming at a crack in the sidewalk 10' in front of you and adjusting can radically improve things. Or just aim at a player standing out on the field and adjust until the DOF centers around the grass at their feet in the way you wish.
AND if you mess it up, how hard is it to hit reset and put it all back to zero? Is that any harder than doing anything else you can do with the camera?
Is it that rare for a rebel user to try to shoot some sports or wildlife or portraits ir whatever with an 85 1.8, 70-200 2.8, 300 f/4, 50 1.4 (granted this lens is so dodgy it's pretty hard to figure out what MFA to use but that is a problem specific to that lens), 50 1.8, 100 2.8?
AND who says you HAVE to use it? If you find it confusing, don't want it, etc. DON'T USE IT! Just because some people won't be able to understand something means everyone else has to be punished. If you find it confusing then avoid it! That takes zero effort.
I haven't even used a Rebel for like ten years but I'd still like to see them put MFA in them. It's not a feature but something to even out QC. Some Rebels may be spot on, some may be at -10. Some lenses people have may be spot on some may be -15. Why should they have to suffer from that. And having no mention that calibration can be off in the manual probably confuses many a newbie shooter. Maybe they get frustrated and quit using DSLRs even. I get that they are a business and want to push people up. And maybe if it only affected f/1.2 shooting by a couple inches you could call it a pro feature and certainly 5D3 focuses a lot more precisely than a 50D even if both are calibrated, but not having MFA can even mean that f/4 shooting can sometimes be way off which seems beyond simply calling it a pro-precision to feature to me.
And removing it from the 60D after the 50D had it (and not having put it in the 40D) was pretty cheap. And you say ok send it in to canon. Yeah and then maybe miss two crucial weeks of a season or maybe they mess up say the 1D3 AF and are so busy fixing that they can't be bothered to handle calibrations for more than a month and then you are stuck.
Anyway whatever, I've said too much already.
