I've been following CR for quite sometime, but only now joined the forum.
As someone who got into the DSLR realm only 5-½ years ago with my current Rebel T3i and a handful of basic lenses, I have been anxiously waiting for this 80D/7D replacement model for over a year.
I would consider myself an advanced amateur, and am wanting to take the next logical step up. I'm not quite at the level of needing to go deep into the 5D/6D FF world (financial-wise and otherwise). And, IMHO, the mirrorless industry is still in its infancy.
Getting a top-of-the-line crop sensor DSLR, plus getting a few more new/better EF lenses (I already bought my first L lens secondhand - the 70-200 F/2.8 for half the price), including the Canon EF 85mm f/1.8 (to step up from my Nifty-50), Tamron 18-400mm F/3.5-6.3, plus a decent macro lens and a decent wide-angle lens for landscape photography.
I figure that if my abilities over the next 5 years take the next logical step (in becoming a part-time professional), it is then that I'll move up to a FF, with mirrorless technology being much more mature by then. I could imagine an well-tested "R-5D" with an EF adapter as being my next step up in 2024.
So, for me, this "90D" will work perfectly for me. Been chomping at the bit for many months now.
