New refurbished T5i

[azspots]

My T5i arrived the other day and have a question about the ISO. When I change the ISO on my SX40hs, and

am looking at the LED screen, it is VERY obvious when I change the ISO. On the T5i, it is barely obvious. Although

I do realize these are two quite different cameras, shouldn't it be equally as obvious when changing the ISO on

the T5i from, say, 100 to 3200?

Are you looking at the LCD screen on the back?  Seems pretty "obivious" to me.

I am looking at the LCD screen on the back. Apparently, I'm missing

the "obvious", or I wouldn't have asked 😉

Some cameras have the ability to try to show you how the scene will actually be recorded. If that's what's happening here, and if you're relying on the camera's autoexposure capability, you wouldn't expect a change of ISO to have much of a visible effect, unless the lighting is so bad that available aperture and shutter speed corrections couldn't handle it.

With the camera in "manual" mode ("M" on the mode dial) -- and no other mode -- and if "Exposure Simulation" is enabled and you are using "Live view" mode (not the recommended way to use a DSLR camera -- much better to learn to look through the viewfinder and there are several reasons for this) then changing the ISO will have a noticeable visible effect on the brightness of the image you see on the LCD screen.

If all of the conditions above are not true, then you will not likely see any effect.
