22-04 Nikon AF Nikkor 35-70mm F/2.8 (Listing). Understanding a vintage lens, please read.
Layman terms: This video describes some of the issues you might encounter with a vintage lens particularly the issues with compatibility. Ghosting is similar to overexposure. Ghosting can be created by a fault with the glass, the electronics or just a known fact with a particular model of lens. It can be amazing or troublesome depending on the condition of your setup and only a true professional will know best. A modern Speedlight or Camera might not produce the result you want when shooting in difficult lighting. Here is when the AUTO functions go out the window and you have to use your experience & skills to produce the results you want. I've found this lens works beautifully with camera's closer to its era. This video might need a follow up with a more detail explaining how to use a flash or which camera does what. There are various results from individual setups which makes it very difficult to decide whether this lens is for everyone... It certainly will not be for the fainthearted.
