Evan M. SandersJust got this TTArtisan light meter. Some thoughts...
It's quite nicely made. All metal and the dials feel good. I haven't experienced any problems with the iso being too easy to change as others have reported.
You can, contrary to some reports, move the mount around on the bottom. There are extra holes so you can have it in different positions depending on whether you need it to hang to the left or right or be centered. This is really important on rangefinders as it will otherwise get in the way of your shutter dial.
Metering seems consistent so far, but is consistently under exposing by one stop. I can work with that.
Consistency is more important than accuracy with a meter.
