I bought this for a wider view on my Canon m50 with a 15-45 lens. At first the wide viewing angle didn't convince me, I'll keep playing with it. BUT, when I removed the wide-angle lens, I accidentally unscrewed one of the two parts! There's a larger wide-angle lens and a thinner macro lens. I couldn't understand why my close-ups looked so good. The left part of the macro was awesome.!
