A discussion.
MFT is still usedful in some photo shoot situations, if the pro photogprapher cannot afford better full frame or APS-C equipment.
Note what Robin said from 7:23 to 7:50 about MFT.
Note what Matti Sulanto said at various parts of the video. When client pays you Top Dollar $$$$$$$ "obscene amount of money" to take professional photos of a highly technical engineering nature in an industrial environment. You need to use the best equipment you can afford.
Don't try to turn up with MFT camera + lens and insist that MFT is "good enough" for the client.
It is an insult to the client and highly UN-profesional of a pro photographer to try that.
Matti Sulanto said in old film days, medium format was important for certain professional shoots - like advertising.
The current digital medium format sensors are not the same size as film e.g. 6cm x 6cm or 6cm x 6.45cm or 6cm x 7cm.
Still a long way to go for digital sensor sizes to improve.
