Query: Works great--you can shorten the length, too...

Works great, at first I couldn't reach focus with my dslr (tube was too long), but all I did was simply unscrew each end of the adapter, remove the extension tube, and then screw the two ends back together without the extension. I am now able to reach focus. FYI, you may need needle-nose pliers to get the camera side t-mount threads off of the tube, but they'll for sure come off.
