My thoughts on the new Canon 5Ds & 5DsR which have canon's new 50 MP sensor in them. The 5DsR is pretty much like the same thing between the D800 & D800e. So is it really worth selling all my Nikon stuff to get the new 5DsR? Well in my opinion no because there are really no lenses that will support the 50 MP sensor. Like I have both the D810 and the D800 and they are both using Sony's 36.3 MP sensor and there are really no lenses that will let u utilize the 36.3 MP that the Nikon offers. So for that reason I will not be upgrading to the new canon 5DsR, I am very happy with my Nikon gear. And I know that sometime either by the end of this year or this time next year Nikon will be coming out with it's own 50 mp sensor and since I already have a bunch of money invested in lenses and other things I will stay where I'm at. But let me know what your guys thoughts on this issue are.
