AV setting on Rebel XT question

[funpix]

Still just experimenting with the new camera and have noticed that when on the AV setting it takes an extremely long time to write to the card. I have a 512 Extreme. Any reason for this? I was thinking that it may be the buffering time but then why only on this setting is it affected?

The mode (Av, Tv, etc) shouldn't make any difference, plus you have a decent sized buffer so it shouldn't matter. How long is it taking to write an image, and what type of image (RAW, RAW+Large JPG, etc)?

Try the following suggestion:
- reformat the CF card then with the following setting.

Shooting Mode
Aperture-Priority AE
Tv( Shutter Speed )
10 Try to keep at least 1/60:p
Av( Aperture Value )
29.0 No point to set that small, unless you need some special effect.
Metering Mode
Evaluative Metering
Exposure Compensation
0

Exactly.

They way I read that exif is that it was a 10 second shutter speed. No wonder it seemed to take forever to take the shot or write to the card. The shutter was open for 10 seconds!

That's the way I read it!

The longer your shutter speed, and the higher your F-stop number; the longer it will take for the image details to write to the CF card because the camera has to take 10 seconds to store all the information to the buffer, then send it to the CF card.

Thanks for all the information. I have adjusted the time and it is working better for me. I just have to get past the camera shake.

Funpix, if your shutter speed is fast enough, camera shake shouldn't be a problem. The general rule is shutter speed = at least 1/lens focal length.

I see it says Noise Reduction was "Off". You also might want to check that it really is. If it's recording "Off" but was "On", the camera'd take the same amount of time as the original capture took getting the noise reduction readings to apply.

A little OT, but...
In my experience so far with my 350D, you can leave red-eye reduction off permanently. I've only had one instance where I had red-eye at all, and that was on one of my daughter's friends with bright blue eyes. And it still wasn't bad. With my old camera, every flash shot I took of him looked like a freakin' demon, his eyes were so red. Now it's just a mild red tint, or none at all. That's one unexpected feature of this new camera that has been a great surprise.
