Just joined ! Photo crazy but very amateur !! user of a 1100d ...recently purchased a 80D and struggling a bit with it...the settings I had got used to on my 1100..are not as straight forward on the 80! help!
Welcome to the forums Wooyi! Your 1100 had one screen and which merged the camera settings menu and the shooting settings options onto that display. Now you back display focuses on menus and displaying reviewing images and most the shooting settings are on the top display. You also have now two dials that allow you to set aperture and shutter on the fly and by the press of specific buttons use the dials for quick updates to focus, ISO, etc... If you are tuned into the camera and shooting on any mode that is not fully automatic you will find this to be so much more intuitive and 20 times quicker than any manual shooting on that Rebel. I would say that it is worth a read through of the manual or watching some videos so you can familiarize yourself with all the new functionality, getting reps in on the camera is by far the best way to get that understanding and muscle memory.
