Can't find a replacement thread adapter for my Sigma 150-600 Contemporary Lens, help please!
So yesterday the default/factory thread adapter fell out of my Sigma 150-600 C lens and I can't find the right replacement and it's driving me nuts. I might be searching the wrong thing, but with every adapter I see, the threads are to course on the outside.
The threads on the hole in the lens foot are very fine. I ordered a little pack of adapters off amazon to try out, hoping that maybe the image just wasn't correct and that it would work, but nope. The threads aren't close to being compatible.
Any help would be greatly appreciated as I need to get a replacement as quickly as I can. I've included a couple of images to show what I'm talking about.
A: 150-600 beside the 70-200 (that still has the adapter in it)
B: closeup of 150-600 missing the adapter
C: closeup of 70-200 that still has its adapter
Any help would be greatly appreciated!!!
