Adjust "Exposure Compensation" very quickly

I just got a Canon 90D and like to take photos for birds.

I knew that I can use "Q" button to adjust "Exposure Compensation".

Is there any way to adjust "Exposure Compensation" very quickly (e.g. One step)?

Half press the shutter button then rotate the rear dial. Clockwise for brighter, counter clockwise for darker.

Make sure the dial is not in locked position.

Alternatively you can assign the set button to exposure compensation in custom functions. You keep the set button pressed and turn the main dial.

Yes, I just learn this way and like it.

I set up in this way.

M mode, ISO: Auto, I hold Set button and then turn main wheel to adjust EC but ISO is changed also.

Does it mean that EC change is the same ISO change?

I don't like ISO changed to high (MAX: 1000).

Is there any to only change EC but make ISO not too high?

In manual mode and auto iso the only parameter the camera can change with EC is ISO ofc.

If you for example use EC in Av and fixed ISO the camera will adjust shutter speed accordingly. in Tv mode EC will affect only aperture and so on.

Tl;Dr, EC can only intervene where there is some parameter left to auto.

About max ISO, you can set in the menu what maximum ISO the camera can use (Red menu, tab n.2, iso speed settings, Auto range)

I have EC set to the * button on the back, next to th AF-On button.

To apply EC I press and hold the * button with my thumb while turning the Main Dial with my index finger.

Yes. You know, this is all in the manual. Have you read it?

ISO going higher with a manually chosen exposure does not give more noise; it only makes the default JPEG or review image brighter (usually with slightly less noise). It is your chosen manual exposure that primarily determines noise.

EC in Auto-ISO M mode IS an ISO bias control. They are one in the same.
