EOS 10D Camera Settings by Chuck Westfall

Hmmm. I just did another experiment and, to my surprise, when the camera is set to one shot mode, pressing the shutter button halfway locks the exposure! Now I KNOW that's not how it behaved before they upgraded my firmware to 2.0.1. I always had to use the "*" button to lock the exposure when I wanted to expose at the certain spot and then recompose the frame. Now, the exposure just locks in so I can recompose the frame without even pressing the "*" button.

At this point I'm not sure if this is a good thing or a bad thing. I'll have to think about it before sending an email off to Canon tech support about this new "enhancement".

[edit]OK, just checked the manual and it looks like that's how it's supposed to behave. Oh, well!

For those of you planning to shoot an NCAA tournament game, here's Sports Illustrated guide on how to set up your camera and its custom functions. (They're a bit different that Mr. Westfall's.)

PacAce, as you later found out, your first statement is incorrect. Just to clarify, when using the default of C.Fn-04-0 with one-shot mode, pressing the shutter halfway sets exposure lock but only if you are using evaluative metering.

The appeal of C.Fn-04-1 and 04-3 is that you can lock focus on your subject, recompose, and then use evaluative metering for the scene, without locking AE at the selected AF point.

Thanks. I just changed CF 1 and CF 14 (CF 3 was already set).

Thanks, slejhamer. Just as soon as you think you've got the hang of how things work with the 10D, you go and change one parameter and all of sudden, it's all bets off. Hmm, seems like we should have a list of "This is how the 10D works except when you do this or change that"!

Great links and post, very helpful.

Just when you think you know what's going on another piece of info comes in and crumbles everything. Once again I feel like I don't know what I'm doing. I'm gonna put it in "P" mode and just shoot....

Hey, nothing wrong with the "p" mode. I used it a lot myself. You just have to understand how it functions and where its weaknesses are so that when the occassion calls for it, you can switch out of P mode and use a more appropriate mode. Each mode has its purpose and, as far as I'm concerned, to say that one should only shoot in this mode or that mode, to me, is ludicrous.

I'm actually starting to think that I should put the camera in "P" mode when I shut it off - just for the simple reason that it is ready to shoot when I turn it on. Maybe "P" stands for "Park", just like on a car.

I put mine in Tv mode and work from there when I shut down.

Actually, I'm more of an aperture-priority person (and I'm not sure if there's some hidden Freudian meaning there, but lets assume there is NOT) - that's where I use my camera the most. But, in the interest of not leaving the camera in "Manual" "Bulb" mode (yes, I did that once), or f/2.0 or f/22 when I shut it off, I'm thinking along the lines of making the camera as automatic and ready as possible upon shutdown just in case I have to pick it up and shoot quickly.

Maybe a checklist is in order, at least until I learn to check everything out at shutdown (and maybe startup).

I shoot mostly AV mode as well, and I always drop the camera into P mode when I shut it off too. The one that kills me every time though, and I think I'll have to get a tatoo on the inside of my eyelids as a reminder, is the mirror lock. I always forget to turn it off, and worse, forgot I used it the day before (or earlier that day... whatever the case may be). My heart stops momentarily as the viewfinder freezes black, until that fraction of a second passes and I realize that it isn't a broken shutter, it's just me, yet again playing a practical joke on myself with the mirror lock up.

ROFLMAO

I one spent over an hour with my camera thinking it was busted because the shutter wouldn't close. Finally it hit me that I had MLU enabled. DOH!

Slejhamer, this is a good description. Well, C.Fn 04-3 is very useful for lock focus and recompose when using FLASH.
