Just wondered how feasible it would be to manufacture an attachment for the RRS and/or Millich L-Plate that would attach with 2 screws in place of the grip? This would essentially be a vertical arm to the top of the camera with a horizontal arm that reaches back and has a cable release adapter built into it over the shutter button. It would block the front of the wheel surrounding the shutter button, but this would still be operable from the rear of the camera.
Is there already a better option available? I had thought of buying the strap adapter (Kaiser Cable Release Adapter (Strap-On) 206154 B&H Photo Video), but $35 is way over priced when something similar built into the L grip would be far more practical.
Anybody have any thoughts? Alternate proposals? If there was enough interest I would contact RRS and/or Millich to see if they would be willing to make such an accessory. This post is just to see how crazy the idea is and gauge the interest in such a part.
