I have an old SHUTTER with a new twist. It needs no springs or per se
moving parts. It is adjustable for 1/4 to 1/500 speeds with the greatest of accuracy that never changes. They are non evasive to your camera as they just slip onto your lens, unlike the Packard shutter. We have spent tons of money, six months designing and testing this shutter, and it is now ready for production. These shutters are ideal for any camera with a barrel lens. We will need the outside diameter of the lens to custom fit the sleeve of the shutter to your lens. The sleeve can be larger than the lens and fitted with foam rubber to accommodate a smaller lens. I have posted the photos of the proto-type at the following link. If you would be interested in one of these shutters then do not hesitate to send me an email with your order or you may have more questions about this product. The price is $125 per unit. I forgot to mention that we can fit the shutter with a flash sync. for and additional $15. Why buy it if you never use it. contact me at: rtincher@prtcnet.org, or rtincher@hotmail.com.

I'll be looking for your reply. Ron Tincher

Gravity works! Nice idea but how do you change the exposure time?

The exposure time is controlled by an opening between two curtains that is set by the operator. This is what makes it work, and I must say that it works almost perfect. [nothing is perfect]
