Absolutely love my filter system and the nice gift that came with it was a wonderful surprise!!
Three words to describe my experience: LOVE, LOVE, LOVE!
The large ring does not fit on a 77mm Sigma 17-50mm. If fits on the Nikon lens but not Sigma.
I love the omni system and have the large ring. I wanted to be able to use the omni system some of the other Lensbaby lenses that I own so I am so excited to have the smaller size now too!
I ordered the wrong size to begin with and had to reorder. It has a learning curve like all of the lensbabys. So far I’m not getting much but will keep trying.
