Desmond Long Quick Release Plate (250mm)

While a little bit of a misnomer in that the attachment screws for the camera are Allen head screws, and you can attach your quick release plate to the rail, or attach a threaded tripod head to the rail, so it is not that quick, but that is a minor triviality, the rail is quite stout and worth the investment if you need to support lenses with it. I have the 460mm-800mm Opteka zoom sells, and it improves the image quality, and gives you peace of mind that the lens is not going to lever the front of the camera off. There is even enough room to fit 2x converter between Opteka Lens and the camera. Though one can compensate for various vibration sources, water vapor in the atmosphere does limit some resolution of the image, but it is still a presentable image- better than one I had on hand that did not fit very well and could anchor only to the camera and tripod, no place to secure the lens foot down, so it would bounce around a little more than usual.

Using this as part of a home-made long lens support. No issues at all; great price compared to others offering the same thing. Buy Desmond before they raise their prices!
