Enough of these "amateur" categories. A lot of professionals were shooting and still are shooting with 5D2 which we can say is beaten/on par on almost all camera features by 6D.
+1 ... esp. since a pro starting off with a business is completely different from a seasoned pro with a big budget and lots of assistants - if you're starting off €1000 can buy a (better) lens that make more sense for the business.
But as all marketing divisions know, people have an inherent need to sort things in a linear fashion with as little overlap as possible, but I wouldn't let that cloud the fact that a 5d3+Tamon24/70 will have worse iq than 6d+Canon24/70ii if you're not shooting sports and the af cannot keep up or have to rely on the non-center points.
I have to agree here. I think what is getting overlooked by some is that "professional" simply means one gets paid to take pictures. There is a little shop near where I live that takes children & baby pics- the owner there uses a T1i and 28-135 lens (plus alot of fancy studio lighting). Imagine my horror when we showed up & my wife shelled out $500 for all sorts of prints and frames. BUT I have to admit; photos came out pretty good actually, an in the end I was impressed with the quality of product she provided despite having "non-professional" equipment.
The gentleman that shot my wedding 4 years ago had a 5d classic; I'm sure he would have been thrilled with a 6D and still done a wonderful job. But put a 1Dx in the hands of my father in law, and you'd probably get a lot of nice photos of the back of your lens cap...
I am just a hobbyist myself, and plan on picking up a 6D anyway- but if I WAS starting a business as Marsu42 said, I agree 100%... I'd save the $1000 and use it towards glass/marketing/etc. Then when my company got huge of course I'd let my assistant use it
Long story short, to classify a 6D as only for amateur potraits or landscape I personally think is unfair. While many amateurs/hobbyists (myself included) will be the purchasers of 6Ds, I don't see why event photographers needing to replace a 5Dc or 5Dii wouldn't think this camera would work for them.
