I was wondering if anyone knows of a fix that I can do before sending my Canon 7D camera out to be fixed? Problem: when I set my mode to Shutter Priority, it will change the setting as if it was measuring ambient light, rather than be a fixed setting. Once I have dialed in the shutter speed I want, it remains there till I press the shutter half way, and it changes to a much lower shutter speed. Aperture priority setting works and does not change. I have cleaned all contacts. I was wondering if there is a way to reboot the camera? The camera is at least 5 yrs old more like 10.

If that doesn't do it the 7D has a hard reset that involves removing the batteries, turning it on and off then putting them back in. You can find instruction for that by googling 7D Hard Reset.

You also might check to see if you have the latest firmware, if not, install it.

If those don't work, then it is time to contact Canon.

You're camera is fine, and is actually doing what it's told, as there's a function known as Safety Shift that is overriding your settings.

Reset button/procedure - check your manual. If you don't have a manual, go to Canon Worldwide website, click on Support tab and look for manual downloads.

ST3v3M Bingo. You corrected my problem thank you. No matter how many years I have been shooting, there is always something to learn. I was just set to buy another Canon 7D-2.

In the article, it says-

In Av mode, Tv/Av Safety Shift works something like this; suppose the camera is set to f/2.8 and the metered shutter speed is 1/16000th of a second, 1 stop faster than the maximum shutter speed the camera can support. Without safety shift, the image will be 1 stop over exposed. With safety shift, the camera will automatically stop the lens down 1 stop so youre shooting at 1/8000th at f/4 and the image will be properly exposed.

If I stop the lens down 1 stop, from f2.8 to f4
and then add one stop by doubling the T/v, 1/16,000 to 1/8,000
do I not have to same EV?
Am I missing something? Brain cells notwithstanding. :lol: :lol:

This was what caused me such problems when I first got my SX50 - my first digital camera, and a great piece of gear with the worst manual in the world. I was trying to shoot Christmas lights, and no matter what shutter speed I set, it would ignore me.

My annoyance was because, if you don't know such a feature exists, you can't look it up if you don't know what the manufacturer has called it!

My previous camera had been a Canon A1, so I had skipped about 4 generations of complexity. I just feel that there should be an easier way to find out about such 'hidden' features, and that they should be 'off' by default. The one on my 7D must be off by default, since it has never bitten me.

I know I gripe a lot about the SX50 manual, but really, pick one up some time and try to read it... I don't think there is a single paragraph which does not refer you to a different page. For a camera which will be a starter system to many shooters, it is unfathomable. For some reason, when the 5DIII came out, Canon emailed me a user manual for it. Without having ever used a digital camera, I was able to read that and understand a lot of it.

This seems backwards to me... The best manuals should be written for the starter cameras, surely? Most people who buy a 5D will already know and understand aperture priority, or exposure compensation...

I think you have misread the explanation.

The proper "metered" exposure would be f/2.8 @ 1/16000, but the camera can only achieve 1/8000. Since you are shooting in Av mode the camera wants to stay at f/2.8, but with the limit on shutter speed the photo would be overexposed by 1 stop. The Safety Shift overrides the "fixed f-stop" of aperture priority and changes the f-stop anyway.

Of course, if you manually change the f-stop in Av mode everything will be fine.

I'm with you now. Thanks, JohnFrim.

Remember, on any setting such as aperture priority you're only setting the aperture and leaving the rest up to the camera so other settings will change based on the lighting situation.
