Yes I used ist-ds or an M43 in spot meter mode before I got my Pentax 3/21 exposure meter.
I prefer spot metering to home in on the bright area and the area of interest and decide the setting.
Last night I took a test shot for DOF of the Super Takumar 6X7 1:3.5 55mm, exposed with the spot meter recommending the large area of snow in evening sun at about f/11 and 250th for Kodak Ektar iso 100.
The histogram below is not of the film, it is of the scanner's remapping to the jpg. I have to say that I can not manually better the scanner's algorithm.
