Adobe Master Collection CC 2018 Update 2 64 Bit
the lens has no correction for minuses or fevers but an even worse problem is that it can be focused to infinity. i have 3 different prime lenses with an empty focus ring and the image when focused to infinity is still decent. what is the easiest and most simplest thing to check is to start with a iso of 400, aperture of wide open and let the camera decide the focus point. if the image is still decent and sharp enough to use your eyes to judge it is probably fine.

assuming you aren't talking about live-view. picture mode lets you shoot in raw and jpeg simultaneously. jpeg is always compressed. raw is always uncompressed (except in rare cases like long exposure m-monochrome).
no, normally the i and i would be switched, not the "i" and "i". and no, the frontmost program has no effect on the settings in the rear. i haven't tried this in a while, but i'd think that programs just don't have access to settings in the back. usually they get access only to those that are for the only the program they are intended for. if you can open the rear then you can see that there is some kind of colour tab, but no backlight nor sharpness nor vibration compensation tab. it's normal that there's no such a tab at all.
