Got this European dandelion in, installed and programmed it.
The good news is that it functions as advertised.
But for me anyway, it sadly does not work as advertised.
The issue with it is that the range of focus that it confirms is so large that it is basically useless for me.
I can AFMA it such that when slowly focusing from further out, when it first confirms, it is in focus. The problem is it just keeps on confirming as I continue to slowly focus closer in, and then I have this massive front focus.
The Chinese chips that support AFMA have a very narrow range that they will confirm, which is great. But unfortunately they don't work with 5D3 for some reason.
I need the AFMA since this Rokinon (Samyang) lens is a Nikon mount and I'm using an adapter. The thickness of the adapter is too much for the in camera AFMA to compensate by itself....
I guess it's time to punt on this lens, which is sad because I really like it.
