It works well and the coupling to the shutter speed dial helps speed things up. There are no major issues but check carefully any meter you buy. The most common problem seems to be a missing or broken off battery door. So be gentle when changing batteries. It is also common for the circuit board to oxidize and develop breaks. New circuit boards are available but they are not inexpensive. Usually you can just run a wire to get things working again. The worst problem is a broken or damaged meter coil/indicator unit. The part alone is more than a MIB meter so do not buy one with a indicator that just flops around. It is getting difficult to find mercury batteries but it is simple to have it adjusted to take silver cells. Do not use the alkaline cells as your meter readings will change as the battery discharges. There are various adapters you can buy or make but they do not always work well. CDs meters are a little bit more sensitive to the yellows and reds, have a memory problem when exposed to very bright light (five to ten minutes to settle down after being pointed at the sun) and need time to stabilize when measuring very low light. Nothing to worry about, just things to remember. John Collier PS: Ugly ones are cheap but work just fine.

Is it a good way to go, does it give accurate readings? - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
