[rollei_list] Re: shutters

IMO performance is equal between them.
The 2nd generation Synchro Compurs use a different type of mainspring arrangement that eliminates the booster spring used in the Compur Rapids and early Synchro Compurs. The advantage is you can engage the top speed while the shutter is cocked.

Shutter Question:
I have a number of older pieces, Rollei and Zeiss, with Compur-Rapid shutters. My Cord 5 has a Synchro-Compur. I've been told the 2 types are internally different. My question is /performance./ Does the Synchro-Compur do a materially better job? How accurate is a Compur-rapid in good nick? PeterNebergall
