There are a great number of people who are lazy enough to think that what they have is the best for what they do, because someone else says it is the best for what that other person does. Which if these folks were to actually be capable of verbalizing their feelings, would lead to an obvious epiphany. The fact that NASA uses the hubble telescope to take pictures of the universe, does not make it the best camera for taking images of wildlife. The fact that they haven't come to this epiphany would suggest they aren't intellectually capable of verbalizing their own assumptions and feelings.
Or to put ti another way...
It doesn't matter what you say, it's beyond their comprehension.
But I understand where they are coming from... if it does what you want it to do, and you don't have to think about anything... it doesn't matter about anything else, right?
In trying to hand him your camera you are trying to defeat one of his objectives... not having to think about it. IN his mind you're an agitator, rabble rouser, transgressor of all known laws of camera acquisition.
I mean seriously, would you change you camera universe , debasing everything you know about cameras, just cause some dude wants you to try out his non-conforming hardware. Let's not even call it a camera. We don't know what it is, but cameras are all Canons.
You need to be careful, from his perspective, some form of retaliation may be in order.
Especially since being excommunicated from the church of Canon could possibly be an out come.
You're playing god with someone else's universe.
