I was boring this afternoon and I decide to test a little wide angle combo.
On one side, the Vivitar 24mm f2. And on the other, the Raynox 0,66x that I bought for my HDV camera.
f2 :
f2 :
f4 :
f8 :
Raynox 0,66x with 52mm deforms less than the 42mm one.

In theory.
I think that blur present in the right corner comes from a misalignment between the two lens. I actually used scotch tape to connect them
