I do not make recommendations about brands or models, and I am not a camera technician so I may not be able to tell you what is wrong with your equipment if it`s not working .

Question Hi David, I am so confused, I understand the lighting ratio in studio photography but still can't quiet understand what setting to put the camera on. If the main light is f11 and the fill light is f5.6 and the shutter speed is 60 what should the aperture be set on? Thanks, Lillie
Answer The main light is, presumably, lighting the most important part of the picture.
So the aperture should be set for the main light, in this case f11.
The fill light is presumably lighting the less important part (the shadows ?), which will be, in this case, 2 steps underexposed, to achieve your desired ratio.
Basically expose for the main light, and adjust the position and / or brightness of the fill to control the lighting ratio
