Facing problems with t5i Av mode.

[rafikul1983]

The camera everything works fine except Av mode of the camera. When I try to take a picture and clicked the button its taking much time and red light is blinking, then shutter sound can be heard and then in the display screen it is showing Busy. After staying busy for few while finally when it takes the picture, the picture is almost blank with white color. It’s happening all the time when I try to take a picture in Av mode and with any of the lens.

*This problems happen when in Av mode and f/22 and exposure 4/5

when low the f stop number and exposure, its works but when exposure is high and f/22 its hang and then picture comes out a blank  white screen.Is it normal? Has any one faced same the problems?

f/22 is a very high f-stop unless you're using a tripod.  What do you mean by "exposure 4/5".  

The camera has an exposure compensation mode, but that should normally be set to the 0 position unless you're in special circumstances where you want the camera to deliberately either reduce or boost the exposure vs. what the meter reading wants to do.

My first thought is you have jacked up settings.  Put things back to normal and try again.

My interpretation of the problem is too short of a shutter speed for the aperture used. At F22 you will need to be shooting in VERY bright light to hand hold so that means you need to be on a tripod and wait out the long shutter speed needed to get the shot. Depending on the available light that could be several seconds or even longer.

That explanation would make sense if the reported symptom were underexposure. But what the OP reports is significant overexposure.

The big wait may just be a super long shutter the camera thinks necessary for his f/22 aperture. The blank look might just be massive blur from all the camera shake if the overall scene is kind of bright?

Why are you on f/22? Are you wanting a super deep depth of field, or are you just messing around trying to get something to work?

Also, what do you mean by "exposure 4/5"?
