Sorry my post has gone a little rogue here (off-topic). One final statement. What is the number 1 cause of friction in any relationship? Whether inter-personal, or say between a customer and a business (of any kind)?
Answer:
Our expectations - of the other party/person, product, service, etc.
Example: Canon's 6D Mk II.
Does the 6d Mk II take great images? Does it work properly? ...? ...? etc.? By all accounts, from those that purchased it, YES.
Does it have short-comings? Yes
Has every camera model introduced over the last 80 years had short-comings (for the time it was introduced)? realistically. YES.
But some, even many, models have at least met, if not exceeded, EXPECTATIONS. Example: 5D, 5D Mk III, in some ways the 5D Mk II (think video), 1DX, F1, AE-1, T-90, EOS 620, (and these are just a few of Canon's models).
