Do you know where I can find a tripod collar for the K 300mm.
The inside side has to be 75mm.
Thanks

I bought a $12 collar off of eBay that solved my issue:

no problem - I went through a similar search when I bought mine.... then I bought an A 400mm, so the K300 doesn't get as much attention as she should...

one note on that collar: it fits right at the aperture ring, so if you are going to change apertures alot during the shooting, it'll be a pain...
