Question about my Rebel XT

[hasan_Z]

Hello everyone,

I have just got my new rebel xt a week ago and been going great. Im not a pro, so i bought it to learn. The camera has been functioning great so far. Yesterday however, I went out side (not 1st time) to take some shots and was a bit too hot. At one moment the camera would AF but wouldn't take the picture. Everthing seemed to function correctly, all the displays ect. But it just wont snap the shot. I changed the modes, changed to MF, and it wont take the picture. Not until i changed the ISO from 400-200 did it take the shot. I was in the sun for less than 5 min. Now it works normaly again.

Sorry for the long story, but my question is, could the sun heat cause it to do that?
Again im still learning on this camera.

Thanx in advance for the help.

Could it be, that outside, with your current shutter/aperture/program settings, combined with the available light, and the high ISO-setting, the exposure would be so wrong, that the camera refused to take the shot?

[hasan_Z]

Thats what I'm wondering, because it was in Manual mode, and only when i got in the car, in the shade, lowered the ISO that it took the shot. I also forgot to mention that I did turn off the camera then back on to see if it would help but it didn't.

I was outside testing how different the picture will turn out depending on various aperture/shutter/ISO settings just to get the feel of the Stops.

I think Wizard might be right - I'm in the same boat as you, hasan_Z, as in, my camera is brand new and I bought it to learn, but I've had a couple of instances where the camera wouldn't snap the shot b/c something was not set right (ISO, aperture, shutter). Good luck!

At least, if I recall correctly, my 10D won't shoot in certain programs, if the exposure is totally off. (But I might recall wrong)

hmmm, the only time my XT did that is when I had put turned the timer on. It's taken a picture everytime I've wanted it too. Be worth your time to have it looked at I think.-

Only time the camera haven't wanted to take pictures for me was when my nose (yes) touched the setting for single/multi/timer button and if the focus was not hitting the mark.

I was shooting all week in Las Vegas (literally 115-120F every afternoon) with no problems except that the "rubberized" grip coating has started coming off.

Three reasons you may not be able to shoot:

1. AF can't lock. Happens to me mostly in low lighting at low ISO.

2. Accidently switched to timer mode. Usually happens when I try to use the LCD back-light and hit the wrong button.

3. In AV mode, if your aperture/ISO/exposure-compensation combination requires the camera to have a shutter speed of less than 1/4000s, it may refuse to take the shot--this is my guess as to your issue, since "hot" probably also means "sunny" and the problem went away when you set the ISO to 200.

Thanks for the help, it might have been something with the setting or the mode i was in. Because I know that the focus was good, since it gives you a red dot and beeps. I guess I should just keep my eyes open next time it happens and see under which settings it occurs.

Regards.

For the future. If your camera wont take the picture, take a look at the superimposed shutter/aperture settings in your viewfinder. One of them should flash to indicate that they can't go further up/down, if you run into the problem again. At least the 10D does this.

I have a Digital rebel XT and have had the same problem and found that if the green light in the bottom right looking in the viewfinder is blinking the picture can't be taken. If the green light is solid the picture will be taken. The green light is called a focus confirmation light. When the light blinks you have to recompose the picture and I have zoomed out with the lens. I have had this happen to me in macro shooting outside in 90 degrees. Hope this helps it is in the owners manual page 71 under 1 shot AF for still subjects

NEXT TIME IT HAPPENS TRY SWITCHING TO FULL AUTO MODE AND SEE IF IT SHOOTS.
