Canonrumors reports that the EOS-M3 successor will be announced some times after Photokina but still before Christmas. Those are the rumored details:
It will be a replacement to the EOS M3, but it won’t be called “M4”. Say hello to the M5.
It will go slightly up market from the EOS M3.
Don’t expect big ergonomic changes.
It will be APS-C.
A new lens will be announced alongside it, an EF-M 18-150mm f/3.5-6.3 IS is a good bet.
We cannot confirm DPAF or 4K.
Nice…
