Surefoot NX4

This is a bit of an old school style lensplate with serious length (7" long) that fits some serious older glass like 600mm F4's from the 90's to early 2000's. If your lens has no image stabilization, well maybe this is the plate you need. Often these old lenses were massive 15lb monsters with 2 mounting holes, 3/8" and 1/4" both in the bottom of the foot. With this plate you can mount it easily with the extended portion facing forward or backward for best balance for your setup.
