The replacement aperture set rings sit in my now 9 year old Composer lens the lens the same way the original rings did - perfect fit. Plus the woman who assisted me (the situation was more complicated than a simple purchase) was incredibly helpful, cheerful and responsive. Thank you!

I love this. I have an OG lens baby 2.0 and lost the apertures years ago. This gave life to that little lens I loved so long ago.

A friend gave me the muse and I only had f8. This was perfect to change aperture easily in the muse.

I bought a Scout with fisheye lens secondhand, but it was missing the aperture disks. I'm very happy to have purchased the replacement set.

I was confused when I received this product because some of the apertures were marked but 3 of them were not marked. Crystal from Lensbaby helped me out by sending me a diagram with the apertures. I do think it would be less confusing to customers to either have them all marked or not marked.
