EOS 4000D Trouble balancing light

[Alon]

I shoot on the canon eos4000 im brand new to photography and i want to shoot on manual mode i cant go low on the iso or to be on a higher f stop or use any shutter spoed that isnt around a second even 1/60 is problematic here is a the screen maybe something else is wrong

Only if the iso can vary. In fixed ISO, Av mode the camera picks a shutter speed to get a particular exposure. Focal length has nothing to do with it.
