The M10 is a delight, because it's basically a true digital M, while being an exercise in frustration, because of it's dumb-as-a-brick metering system. The solution is to know when to use a handheld or built in meter and to 'learn' the sensor like we used to with film. Also the battery life is mediocre at best and the batteries are $200 a piece.
I`ve never heard this mentioned before.
It`s a shame that they still can`t get the basics right after all this time.
I`m using a 5D3 more and more ,that and the latest Richo
