How can I set the f/stop and shutter speed on my Canon Eos?
Using my Canon Eos XT digital camera, I’m trying to find a way to set my f/stop and shutter speed. When I set them using the manual settings, the camera will change the setting on the f/stop automatically by itself. How can I stop the camera from adjusting on its own?
Do you want to shoot totally manual? Turn the mode dial to “M” and use the command dial up front to change the shutter speed, then while holding down the exposure lock “*” button, turn the command dial again to adjust the aperture.
If you want to allow the camera to do some of the work, turn your mode dial to “Av” to shoot in aperture priority. This lets you set the aperture while the camera adjusts the shutter to get the correct exposure. You can also turn the mode dial to “Tv” to shoot in shutter priority where the camera figures out the correct aperture to match the shutter speed you’ve selected.
It sounds as if you’ve already played with the automatic modes and/or programmed exposure mode “P” where the camera makes it’s own adjustments to get trhe correct exposure. In programmed exposure mode, you can still “shift” the exposure to a smaller or larger aperture as needed to control depth of field.
David is right and mentioned something I totally forgot. If you are shooting a zoom and the lens specs read something like f3.5-5.6, then your aperture will indeed change as to rack that zoom out to the long end of it’s range. This would also occur on my EF 70-300mm f4-5.6 lens but, I almost always use that lens outdoors in good light and never shoot it with an aperture wider than f5.6 so I never run into that issue. And my primary lens is an EF-s 17-55 f2.8 IS. So the aperture is constant regardless of zoom setting and avoids the problem you are seeing.
