Many of my friends are trying to get me to go over to Nikon. Some Sony people as well. But hardly anyone left shooting with Canon (comparatively in my New Jersey groups at least). The good part is, when I lead any workshops, I refer to my co-lead to help the people out with their Nikon cameras - lol.
I lived 10 minutes from the Service Center in NJ, and that, and teh fact that I bought my first Canon 30+ years ago kept me with teh brand ---- It's LOYALTY.
Then the Service Center relocated, then they cut here and there, then they said no 3rd party lenses even though we don't make what still photographers would like us to make. And when we do make a lens, we can't keep up with the demand and it's always out of stock. As a loyal customer, I do feel jerked around A LOT.
But that's teh thing with companies....When you work for one, there is a lot of internal savings, and saying targets are not met, blah blah blah. On the outside the financials alway look good, especially for press releases. It does never really tell the whole story.
So, Canon....what about letting Sigma and Tamron produce lenses we want that you don't provide. Then I can tell people to buy Canon again.
I am not switching (yet). In too deep. But a good tax return, and some extra spending money.....I would not rule it out, especially if you continue to drag your feet on things "enthusiastic nature amataeur photographers" want. Like a lightweight and small 500 f5.6. What, Nikon and Sigma have those? But not for Canon.....
Pffffftttttt......
