1DR will be interesting - but what on earth native fast long lenses are they going to have to compliment it ?? (I'm discounting rumours of an RF 500mm f2.8 lens - I can't see a ~4.5kg++ lens setting the world alight for the walkaround birder ! :eek!: )
Perhaps if Sony comes out with a rumoured 'Pro' model even more capable, ergonomic, and robust than the A9II - it might be game over considering their native mirrorless fast long light lenses already available ! :eek!: Goodness only knows how Nikon is going to match that lot .........
