Seb:
If you are shooting fast moving kids or street photography with slide film where proper exposure counts, the M7 will get some shots you would have otherwise missed while doing the Manual metering.
I was shooting in Paris with Steve Unsworth a few years ago and I missed a couple good shots because of manual metering. I remember one was a lady in a shop doorway smoking a cigarette, gazing off into space. In the two seconds it took to set the meter on my M6, she saw me and turned away. The next year when I was in Paris, I had a M7.
Here is the picture where she saw me and turned away. It was on slide film so exposure was critical.
