feedrail — Tue, 04 Jul 2017 02:58:02 GMT

i use auto iso in shutter priorty (TV) and no matter shutter speed 100 to 2000 its shoot at my max setting 6400? What up? Also if I use it in AV no matter the setting it shoots iso 6400 or if I set max to 3200 all shots are shot in 3200.

Are you outside in daylight? What are your lighting conditions.

It doesn't matter it can be full sun and I can set shutter to 1/30 up to 1/1600 and it has no effect

What lens are you using? It sounds like the automatic aperture might not be working. Try a different lens.

You could try clearing all camera settings and custom functions just in case you inadvertently set something you didn't want. If that doesn't work give Canon a call at 1-800-OK-CANON.

"...its shoot at my max setting 6400..."

What is your minimum ISO setting? Did you check it?

I don't believe Rebel series allows a minimum ISO to be set.

It's been too long since I owned a Rebel to remember. Just a shot in the dark.

I use 100-400 5.6 tried different lens. What ever I sent the max ISO for auto I use, that's the ISO it uses.

What happens if you set it to P mode?

What Av value is the camera setting when you are in Tv mode?

Is that the latest Canon "L" lens? We cannot see your camera, so you have to tell us about how your camera is set. If you call Canon, they will ask you similar questions.

What shooting mode are you using? Have you tried the Green [A] mode in birght sunlight?

I think it was a custom function auto exposure compensation override, it either didn't clear when I reset the settings or that it's default - but after changing, it now works but it uses higher ISO than normal but at least it is changing.
