I personally think it's the opposite... Canons in the hands of amateurs have a shitty "dreamlike" undersaturated look.
Of course anybody worth their salt isn't gonna be using the standard color profiles to begin with. My D3200 for example is on the neutral picture profile since it gives me more control over light and color in the post-process stage whereas the D5500 I use at work is on vivid since I don't have time to edit.
It's all a matter of how you use it imo. If you complain about stuff being shitty off camera then something ain't right, unless of course it's intentional(like mine).
That lens should be pretty good for portraits. I need to eventually get a 1.8 85, I've gotten to enjoy 1.8 on my D600 oddly enough, when it hits focus of course. Just check ebay for a lens depending on what it is you should be able to find a deal for it.
Yup, the 70-210 is literally a beast in performance and weight. Performance wise, it's ridiculously good... I can only hope it'll retain that quality when I switch to FF in the future. Weight on the other hand... man, IIRC it weighs about 6 pounds with my D3200. My shoulder would usually hurt at the end of long shoots with it lol.
I have a 1.8 85 but from some unknown brand called Opteka, it works nice and all but the focus is fncked up(it's confirmed in the viewfinder but it's blurred on the actual shot) and the aperture ring is sluggish so I've stopped using it and have used my 70-210 instead.
