[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Doug is right... but the fact is that the dropping resistor does work properly with CERTAIN types of cameras... most notably the types using a simple analog meter. M5 and CL/CLE are the 2 I would recommend. Also the MR series of meters. The faulty measurements occur if you use the wrong type of camera ( meter in the M6 comes to mind) and the voltage on the cell's output goes too low. These meters are "fancier" than the simple manalog meter in the CL. Frank Filippone red735i@earthlink.net >http://www.criscam.com/ >Others on the list have liked the product. The CRIS device contains no stabilising circuit, CRIS told me, and relies on a small resistor to lower the voltage. This crude technique reduces the voltage to a nominal 1.3v, but does nothing to compensate for the poor voltage stability of the replacement cell. I read recently (in either the LHS or LHSA magazine, I think) that Leica does not recommend the use of voltage adaptors, saying that this lack of stability will result in incorrect exposure under some conditions.
