Monster Adapter LA-FE2 Nikon F Lens to Sony E- Mount Camera Lens Adapter

I recently purchased the Monster Adapter LA-FE2 Nikon F Lens to Sony E-Mount Camera Lens Adapter, hoping it would allow me to use my collection of Nikon F Mount lenses on my SonyA7R V camera. Unfortunately, my experience with this adapter has been bad.While the adapter successfully maintained electronic communication and autofocus with some of my lenses, it did not work with many others. Specifically, I encountered issues with lenses that have their own built-in motors. Despite the adapter's electronic contacts providing communication and power supply, I could hear the screw motor turning with these lenses, but no actual focusing took place. This inconsistency was disappointing, as approximately half of my lenses functioned correctly while the other half did not.I appreciate the effort put into creating a product that bridges the gap between Nikon F lenses and Sony E-mount cameras, but the performance fell short of my expectations. The concept is fantastic and much needed in the market, but the execution did not meet the advertised claims in my experience.In summary, while the Monster Adapter LA-FE2 has potential, it did not provide the integration I was hoping for with all my lenses. I truly wish it worked as promised, but sadly, it did not deliver consistent results for me.
