Review on Sony E-Mount Camera Lens Adapter For Nikon F-Mount G-Type Lenses - Vizelex ND Throttle by Michael Gupta

So here's the thing -- after about a month and a half of using it, the screws started to come loose and it almost looked like it was going to fall apart. I got a eye glasses repair kit (I was on a job traveling at the time) and tightened them up and all seems well. Though it admittedly, it was annoying to have that happen in the first place.Next, I start noticing that some of my photos and footage had this weird vignetting happening. I blamed it on the lens at first but then it started showing up in other shots with other lenses. After a quick investigation, I realized that it occurred when I would crank up the ND on the adapter, which renders the adapter almost completely useless since I bought it FOR THE ND.I bought it exactly 2 months ago and would return it if I could. But it seems I'm past that mark now. Shame.
