Well, I didn't get a chance to use the M5 on a moving subject. Lots of static subjects. Considering I was shooting in cemeteries for the most part, that's probably a good thing. Overall, I enjoyed using the M5, but it doesn't make me want to run out and buy one for myself any time soon (one of the benefits of renting, it alleviates the GAS). The thing I didn't really like was the delay when the viewfinder turns on / switches from the rear display, but I learned quickly I can use my thumb to cover the sensor that triggers the viewfinder before I bring it to my eye, to have it engaged by the time I have the camera in position. I'll post some photos when I have processed them.
