The 40D Live View Mystery -=READ THIS=- Before posting re Live view

I too nominate this to be a sticky for a while. Canon makes decent manuals, but the Live View section was a lot to take in. You also have to bookmark the CF sections and go back and forth to take it all in. I admit I got a little lost.

S2000 why to you suggest turning off the Lens IS if using a tripod?

Because what RoudyRed94 says. Also remember to cover the viewfinder to get proper metering.

IS isn't designed for tripod use and can actually make images less sharp. It's standard practice whether using Live View or not.

This applies only to old IS lenses.
Most modern, second and third generation IS lenses are intelligent enough to detect tripod.

IS makes the image "shake" a tad in LV mode under 10X and makes it tougher for my eyes to manual focus it. Under AF I would agree.

thanks for clearing that up for me!

Thanks...It's a good feature once you know all the ins-n-outs

I have a question about using the Live View option. I just bought a 40D and I am still playing with everything. I am using my 14 year old 28-105 cannon lens with my 40D and it takes decent pictures. I can't get the live view to work. read the manual and enabled the live view but the screen doesn't come on. Oh, almost forgot! After taking a picture, the image will show, so I know the screen is working. Thanks for any help!

great summary. I learned a couple of things!

1. live view is not enabled (try again???)
2. Wheel button is not pushed to activate live view
3. your camera is broken

The lens would not have an effect on it not working. The image would be taken with or without live view being on.

I bought the 40D but haven't recieved it yet and can't wait to get my hands on it so I'm looking forward to any help from every one, I've been a videographer for about 14 years and now I want to be a "shutter bug" as one of my friends call it. One of the things I'm not sure what to get is what type of light meter to choose, I'll be doing portraits and weddings.

They wrong thread for this question, but the in camera light meters for settings will work for most situations.

2. C.Fn III-6 - Enable (pg. 160) - shows how to Auto Focus with LV on. (ps...push AF-ON button & One Shot must be set, mirror will lock up and focus on center point (beep) and then drop to show LV in forcus)

Great thread...thanks for starting it up S2000.

I wanted to clarify though, LV will still auto focus in burst and high speed burst modes too....including in one shot mode.

Ok odd question, but does the mirror going up and down constitute a shutter actuation? i.e. does Autofocusing in LV constitute one actuation?

Autofocusing doesn't take any picture, but perhaps the shutter closes and the sensor turns live view mode off (saves on sensor heating), while autofocus is going on. I don't know, as the mirror going down makes it dark anyway.

One-Shot mentioned above is about autofocusing, not shutter relese (we can't say film transport any longer, can we?)

Finally, I'd be interested in seeing an explanation for why it would be smart to cover the eyepiece when using live view? When not, yes, to avoid stray light entering the light metering backwards through the viewfinder, but in liveview the mirror is up (that's what it's all about!), so the light metering is done by the sensor!
