Now I can finally say my M8 is ready to go!
I met Tom Abrahamsson in person the other day and bought two softies. I've got the red one on the M8 here to match the red Artisan&Artist acrylic strap. Together with the Thumbs-Up installed I've been able to successfully shoot as slow as 1/8th using the finger hook method over the release. I highly recommend one of these for anyone who shoots an M body.
