The cable remote release is just a two circuit switch. One switch turns on the meter and focusing system, the other trips the shutter.
But you can buy the "Canon Remote Switch RS-60E3" from B&H Photo for $25 that works perfectly as a replacement for the $40 Pentax CS-201, or go to Ebay and find the same thing made in China for $4. I personally wouldn't waste the time to make one. Godfrey On Jun 3, 2008, at 7:15 PM, D. Glenn Arthur Jr. wrote: > I went to Radio Shack to buy parts to build myself a cable release > for the *istD.
