DOF Adapter for Vixia HF R82?
So I own a Canon Vixia HF R82 (43mm thread size), and am looking for an afforable DOF adapter. I currently have "Canon fd 50mm f/1.8" 35mm lens, which is manual focus. Basically, I want to put a 35mm prime lens on my camcorder, and have it actually work. I have been looking at products like "Encinema 35mm SLR lens adapter for HD video cameras". This is actually reasonably priced compared to other companies' products.
So, My question is:
Is the encinema adapter my best bet? are there better options for the same price or cheaper? Or am I even looking at the correct thing?
Any help is appreciated, as I am still learning camera and such.
