Q: 1. Would this be necessary for a 35mm focal length or is the regular 67mm adapter ring fine for that focal length?

A: I bought this item for a 75mm 4X5 lens, the equivalent of a 21mm in full-frame 35mm. Works fine at that focal length. However, I suspect the regular adapter ring might work for a 35mm focal length with a 35mm film or sensor size.

Q: 2. Is this wide angle adapter ring compatible with the Seven5 filter system? I'm looking to add this to the front of a 12-40mm lens and I 'm concerned with vignetting from the standard adapter ring.

A: 12-14mm it been consider a ultra-wide angle lens yes you will get vignette if you form 20mm and up it ok. but for more info I recommend you to lee web click on camera scroll down to Lee Match system click on the button Good look Jose.

Q: 3. I bought Lee adapter WA 77mm but can not screw in the front thread of UV BW filter. I tried directly with the filter also does not work. It seems the diameter of the thread is much smaller than 77mm. I use Nikon 24-70mm which has 77mm front thread. Any idea why it does not work?

A: Yes, give this a try. Make sure the side of the adapter with the LEE 77mm W/A is facing the lens. The adapter actually fits over the UV filter. You are probably just trying to attach the adapter in the backwards position. If the adapter does not seem to fit, turn it around and screw it on. I hope this helps.
