Shaking can be excellent for your money maker, but not so hot for your photos. This handy cable release threads into your camera and allows you to fire it in complete stillness - without even so much as the action of pushing the shutter button to vibrate your instrument. A lock allows you to H-O-L-D those shutters open for as long as your heart desires. Compatible with the Horizon 202, Seagull 205, Seagull TLR, Fed 5, and a slew of other fun cameras. 10" (25cm) long.
