Weird shutter issue with t2i

[akouvi511]

Hi! 

I have a wonderful Canon EOS Rebel t2i that I just love to death. I bought it second hand and have been using it for the past 6 months. Today, I pulled it out to take a picture and the shutter stuck! This happens on M & Av modes, but not on any of the other & automatic modes. I checked the mirror lock and that's not on.

So basically, what happens is:

Camera focuses, I press to take the photo and the shutter makes it's regular sound and closes... and then does not open up again. There is a red light that blinks, the screen is black, and after about 22 seconds, it re-opens and the photo is over exposed.

What is happening? How do I fix it? How did this happen? I am currently traveling and won't be able to take it in for diagnostics immediately. 

Thanks for the help!

f/11 at Av together with ISO 100 in that light condition will need 20 seconds.

At least on M, what is the shutter speed set at?

[akouvi511]

It's at 1/250, F6.3

Do you have a second lens that you try?  We need to determine if it is the camera or the current lens.  What lens are you using?

Yes, trying now! I am using an 18-55mm.

I just tried out my 50mm and yes, it does the same thing.

Test it in M mode.  In Av mode, the camera will select a shutter speed based upon the Aperture, ISO, and available light.  A long shutter time could be normal for the conditions. 

Try dialing in the same settings [Shuuter, Apeture, ISO] from the A mode, into manual, and take another test shot.

Wow... thank you both! You are both right! Thank you so much. Now, to return to the basics so that I don't panic and make a mountain out of a molehill because I don't understand the ISO/aperture/shutter trifecta. 

Thanks again! Very helpful!!

Upload two pictures here. One from M or Av and one from Auto. Then we can take a look at the EXIF information bundled in the pictures.

The top is in Av mode, the bottom is in full auto mode
