It seems to me that Canon is like a supertanker, nobody knows what course it's on and nobody is on the bridge checking what all the other shipping is up to. The rudder may or may not work because it hasn't been tested lately and whilst there are currently no rocks on the horizon, there's always the chance of a disruptive iceberg drifting onto a collision course.
Canon seems to be developing a knack for iterating cameras which are perhaps sometimes years out of date on introduction (EOS M first version). The rather expensive 5D4 has a dreadful crop factor for 4K and a codec (MJPEG) I assume was written in the 19 Century. I understand that not everybody wants video in a camera, but certainly I do. So would I upgrade my 5D2, a camera that really started the whole independant video movement in DSLRs, to a 5D4, well no.
I also own the original EOS M, a camera I have a love hate relationship with even when purchased at minimal cost , so I followed the rumours, announcement and initial reviews of the M50 with interest. Based on the information so far, I wouldn't upgrade to this camera either, because:
1. Why would Canon fit this camera with the puniest (EOS M) battery in the mirrorless world when they could have at least fitted the second puniest battery (EOS M5), Sigma Merrills excepted.
2. The dreaded crop factor appears again, Vloggers can forget the selfie stick and swop to a barge pole instead. Make that the long pole version if the Electronic Image Stabilisation is going to be used, which of course it will be.
3. The Crown Jewel of Dual Pixel Auto Focus is to be denied to those daring to venture into 4K, a case of gruel today and jam later, but nobody knows how much later and how much jam.
4. No announcements relating to improving the current lacklustre native lens selection, no road map, more like lost in space. The number of bodies now equals the number of available EF-M lenses, how does that make sense?
5. No proper IBIS in 2018. Yet IBIS can be found in Olympus, Panasonic, Fuji and Sony, in some cases introduced years ago.
I'm just an amateur enthusiast and like most don't make any money from photography. Photography purchases therefore have to be carefully considered, weighing up the pros and cons of respective cameras and lenses. I like my 5D2 and there is no reason to stop using it when the weight and size are not too problematic. But I'm heavily into the M43 system because it is small, light, has a great lens range and is cost effective, expecially for travel or walk about use. Canon has failed to provide a fleshed out EOS M system, had they done so then a lot of Canon photographers might never have needed to venture away from the brand.
