LensCoat® Tamron 2x Teleconverter

The adhesive backing went on without any bubbles, and the cover hugs the converter snugly enough that it doesn't shift when I'm swapping lenses in the field. It's a small peace-of-mind investment for keeping the resale value up.

Fits the Tamron 2x converter perfectly, and the extra grip makes it much easier to handle when swapping lenses quickly. I've already bumped it against my tripod a couple times with no marks at all.

That neoprene fits my 2x teleconverter like a glove and stays put even when I'm swapping it in and out of the bag all day. Nice to know the resale value is protected from scuffs now, since these things aren't cheap.
