Oct 3, 2017, if your autofocus camera lens is not good in low light focusing sports then manual focus is your only best bet.
F-stops of manual manual around f/2 to f/2.8 are generally considered optimal in terms of focusing speed sports and accuracy.
The intensity difference between adjacent pixels of the autofocus sensor naturally increases with correct image focus.
Even then, contrast-detect is more likely to be accurate overall, although the differences arent enough to ruin a photo.Since the effective measurement autofocus basis is an optical property of the actual implementation, it cannot be changed easily.Despite the benefits of autofocus, there are plenty of reasons why you may still want to use manual focus for landscape photography. Manual focus is fine. .

I think ISO 800 to 6400 will do just fine. .With passive systems this will generally not be a problem, unless the window is stained.Applied Photographic Optics Ralph Jacobson, Sidney Ray, Geoffrey G Attridge, Norman Axford.In autofocus mode, the photographer doesn't have to do anything.
The system uses a beam splitter (implemented as a small semi-transparent area of the main reflex mirror, coupled with a small secondary mirror) to manual or autofocus for sports direct light to an AF sensor at the bottom of the camera.
A notable exception is Canon digital cameras with Dual Pixel cmos.
