hi everyone,
i'm actually using a sigma 24-70 f2.8 with a super big filter thread size of 82mm.
it's hard to find a wide angle converter (WAC) for 82mm and even if shops were selling it,
they were really reaaaaaaaaally expensive.
so i tried to post a wtbuy in B&S looking for 82mm WAC but to no avail,
guess not many people are using it..
so i was wondering,
if i can get a WAC for a more common filter thread size with a step down ring,
(i.e. 72mm WAC with 82mm - 72mm step down ring)
will i actually see black spots at the edges ?
something like this :

i'm fine with a little vignetting, but i don't want it to be absolutely black.
thanks for reading !!
