Packard Shutter, Front Mounted
This is a factory-new 3 inch #5 Packard Shutter on a thin, rigid plate with a Cokin style mount.
It's a complete, well built, lightweight, compact, and ready to use unit.
See the shutter in operation here:
"Instant" mode is a quick squeeze and release (about 1/20 second).
A single continual squeeze holds the shutter open for about 90 seconds.
For times longer than about 2 minutes, a second squeeze & release closes the shutter.
• Fits any of my recent Wollaston lenses having a 72mm front thread.
• Fits ANY lens with a standard front filter thread and a commonly availabe Cokin P series ring such as: http://www.bhphotovideo.com/bnh/cont...A=endecaSearch
• To reduce exposure times down to 1/20, use a slower film, use contrast and/or neutral density filters.
The shutter, the mounting plate, and the bulb & rubber tube is $ 250 + shipping.
For Wollaston lens customers, a 72mm Cokin flange ring is also included.
For those folks who want an "instant" mode, I offer the same configuration using a Packard #6 shutter for $279 + shipping.
Inserting a special pin into the shutter yields a 1/25th second exposure with a single squeeze of the bulb.
Removing the pin lets the shutter revert to the #5 mode (fully manual timing).
I use factory new shutters for total reliability.
Here's a quick peek on how I've configured the trip pin on a 3" number 6 Packard...
