It's all about conversion costs.
Well, Sigma are working towards making it easier with lenses that can be adapted.
You misunderstand. I'm not talking about converting from one camera system to another. I'm talking about converting a potential customer into a paying customer. All companies have to do a cost-benefit analysis to determine if a category of potential customers is worth the cost of converting them into paying customers.
The point is that it isn't cost-effective for Canon to try to convert you. You're just not worth it to them.
Would Canon like for you to buy a 5DIII. Well, in an ideal world yes. But they have to look at what it will take to do that. You take way too long to make a decision, you don't spend very much and after the sale you are likely to be a high maintenance customer.
There's a lot of speculation and comment there with no basis for fact.
Not really. You've been posting on this site for years. More than 2,000 posts. It's pretty easy to sketch your profile.
So, it's basic business sense that it's better to concentrate on customers who want to make a purchase, are going to make that purchase in the near future, are likely to make additional after-sales purchases and are likely to be content with their purchase decisions.
They're called "fan-bois" and will do whatever Canon says and buy whatever Canon makes.
Just more proof of my previous point. To you they are "fan-bois." Canon calls them "loyal customers." What Canon knows is that I will open my wallet for their products. So, what I want in new products is going to carry more weight than trolls who seldom if ever actually purchase Canon products.
