I just caught your post. I am also new to using this forum. You have a great idea for a wonderful gift. I might suggest you post this question under SLR Cameras. If you have not already got the lenses this may be too late.
Anyway, still have my Nikon F2. The F2 can mount either pre AI or AI/AIS lenses, but it needs the "rabbit ears" prong to mechanically transmit aperture information to the metering prism. I do not know about the Vivitar, but the e Series do not have this prong. If you can get this part you may be able to attach it to the lens. It is located at the f5.6 stop on Nikkors.
The e series are called Nikon not Nikkor. I always found this curious. I was lucky and only used the later.
