It's not possible to make an autofocus lens like this, that's why I ask if it's possible to make a cropped lens for mimimazing the dimension for who (not me that love only fast prime)like some tele zoom....
In this way "larger" it's "better" because if you want to go small you can, but you cannot do contrary...

Sure it's possible to have AF with this one.
The f/5.6 and f/8 limit applies to DSLRs - not mirrorless cameras.
AF accuracy is simply a matter of sensor noise here.
