Nikon 400mm f2.8 with 2.8x Teleconverters HD

This is my 1120mm setup using a Nikon 400mm f/2.8 AI-S manual focus lens with Nikon TC-14E II and a Nikon TC-20E III teleconverters stacked, effective aperture is about f/8. Also shows just how sensitive this setup is to camera shake and vibrations. Mounted on a very stable Really Right Stuff Versa 34L tripod and a Wimberley 200 gimbal mount. High frequency shutter vibrations are damped using two sandbags resting on the lens.
