Default Focusing?

Probably a stupid question but I was just curious if you guys use manual focus or if you trust the camera to auto focus?

I've been using auto focus and I haven't really had a problem with it but today it screwed some shots up. Lol

Depends on the situation. Well lit and shooting on the fly, changing focal lengths as I go, I'm relying on the auto focus.

Camera on a tripod - moody light - everything locked... I know exactly when I'm pushing the shutter and everything is pre-set - and there's even the slightest hint that there may not be enough contrast out there for the camera to lock in on - I'll manually focus ahead of time and leave it.

My opinion is that you need to go with the situation - that's why you have options. Test the camera before the train comes. Is it hunting? If so, then preset the focus manually.

I use manual auto focus or whatever you would like to call it. Set focus to the * button so you can tell the camera when to auto focus. On the rebel series it seems the only focus point worth a damn is center, learned this the painfully hard way and now always leave it on center point.

On all of my cameras, I use center point only on AI Focus mode. My 2 camera bodies, the 5d, the center point is the only one worth a damn, and the 40d, it's outer focus points are better, but I still tend to only use center point and crop as necessary afterwards.

I have never manually focused.

I use a blend of both modes: Like Charles, if I know what the shot is going to be, I use AF to set the focal point, then switch my lens to MF mode and wait for the train to reach that spot (I learned 35mm photography using a Pentax body which had a split-ring focusing screen and never was able to adjust to Canon's "sharpness" screen). I used that method to create this shot, for example:

Dave, why wouldn't you just leave it on AF?

Only rarely have I ever used manual focus and that was typically night time shots where the AF just was not cutting it. I believe I have used the MF on some non railroad shots in the daytime when I was trying to put a background object in focus purposefully. With the way my eye sight is getting, I don't think I'll be doing the MF thing much longer at all.

Just due to the fact that I usually shoot at far distances (outside of the focal area of the lens focus meter), I set my lens to infinity and snap away.
No need to fool around with AF, that'll come with the new camera's 9 cross-type AF points.

I've used the Live View function at 10x magnification to either focus the shot manually or to verify the autofocus is where I want it. Live View, while gimmicky on the surface, can realy help with that 10x magnification deal coupled with an IS lens.

Otherwise, I'm a centerpoint AF user who pre-focuses on a spot and has separated the focus function from the shutter button (in other words, I'm a * focuser like Jim).

Would the shorthand on that be "Ass focuser?" I mean, if you didn't want to say the whole "asterisk," part of that?
