Very good information  shared...
 
	I have a 70 to 300 nikon dx lens and a sigma 50 to 500 lens...
 
	 
 
	I am debating whether to stay nikon or go sony or Canon...
 
	 
 
	I think it's still too early for the decisoon....for nikon z8 we need a mark 2 to come out as z8 is a first hit
 
	 
 
	For canon we need a R5 mark 2 also to iron out their first hit issues.
 
	.I think when these come out...then comparing them to Sonys best...will be the best way to finally make a decision on which way to go....it's still early...
 
	Plus more lenses will be out to compete with Sony too...
 
	 
 
	Anyone use nikon old DX lenses from d300 /500 years on Sony ,nikon or Canon full frames .with adaptors..that can provide any input on how that's working for you? Would be helpful before I jump....any input would be great....I am moving to my first full frame
