看上了个LEICA M5，价钱不错，想吃下。但不只它的CDS光敏元件的寿命如何？另不知道应如何检查？这个机型有无软肋？请DX赐教。多谢！

sdnk: thank you very much!

Hello Yuan
I personally do not like M5, it is not a classic shaped Leica and big , ugly, There is a small arm carry a CDS photo cell, when you push the shutter the cell move away just like CL.  CDS life span I do not know depend the quality of the cell, some of my old 50's Selenum meter still works even most of this kind cell does not work at all. but most my 60-70 CDS works some lose it sensitivity. unless M5 VERY CHEAP let see $300, I may look at it. Hopes this help and you know English.
