I had a similar thread some time back, the answers all boiled down to this:
Yes they will give the same FOV, but, in practice the difference can be likened to TV's - the 82 degree will be like looking at a wide screen 46 inch TV, and the 50 degree will be the same show on a 14 inch portable.
I bought the 82's and wouldnt go back.
