I use this macro rings with the Sigma 30mm 2.8 and the Sigma 60mm 2.8. This two lenses work perfect with the rings. I love doing macros while I walk with my dog. Sometimes it's a little anoning that you need to change or better to add the ring or to take it away Bit the results are really grate. You also cold as the ring to the Olympus 12-50mm and combine the ring with the macro setting. You even get closer than.
