I started with Minolta for my 1st SLR a long time ago. Back then they were the innovators, produced good glass but they took a wrong turn with the APS film system. Tried to recover with the the RD-175, probably the first digital SLR, https://en.wikipedia.org/wiki/Minolta_RD-175
Have one sitting in my office. It was $5k, at the time of purchase, didn't sell well. After other failures they eventually sold out to Sony.
A little unrelated but, what happened to the lens expertise Minolta should have brought to Sony? Was it ever there or am I just being nostalgic?
Canon has chosen the mirrored road for it's main product line, it will be interesting to see how it compete's against mirror-less FF in the future which is probably only going to get better over time. You have to think they will make the switch if FF mirror-less becomes a threat to sales. Right now Canon wins on glass IMO. So only time will tell.
Personally I don't care either way as long as the AF, IQ, price and DR are comparable. Then there's always the glass.....
