I currently own 3 a-mount lense (from a sony a230) just bought a sony a5000, which is an emount. Will this adapter fit my old lenses to my new camera?
No, this adapter is for the older manual focus Minolta Rokkor MC and MD lenses. If you want to autofocus and aperture control you will need the Sony LA-EA4. (the lower cost Sony LA-EA3 will electronically connect A mount lenses but you will have to manually focus.)
