Lee wide angle adapter question !

I wanted to get the Big Stopper but there is no place to have them in stock so I decided to get the 77mm B + W 10 stop ND filter and 77mm B + W KS circular polarizer. I have a tamron 28-75mm f2.8 and Canon 70-200mm F4 IS, both lenses have 67mm thread. So in order to use these filters, I get the step up ring for that. My question is, if I want to use the Lee system, can I use Lee 77mm wide angle adapter with the 67mm to 77mm step up ring If I have a chance to get the other L lens with 77mm thread?

Thanks

If you mean can you put the lee wide angle adapter on the step up ring then the answer is yes. But you do have to worry about vignetting on UWA lenses.

Thanks for your input

I've got 5 Lee WA adapters in various sizes and none have ever come apart so I would expect that there should be some kind of thread locking adhesive that failed to make it onto yours.
