Has anyone done extended comparisons of the Zeiss BG/A T* 7x50 with any Zeiss 7x roofers like the 7x42? (Assuming the most recent models)
Same for the Swaro 10x porros (discontinued I know) with the 10x50 roofers?
Same for the 2 top Nikon 10x42s in roof and porro model?
Internal company comparisons are the most interesting for me for this particular case.
I'll jump in since it looks like you're not getting much response. I've owned or used most of these binoculars or their nearly identical siblings, but the only recent "extended comparison" I've done has been between Nikons. If you are hoping for a kind of apples vs apples comparison of prism types I think it would be dangerous to make any generalizations about roof vs Porro with any of these binoculars, even comparing within the same brand, because too many other important design features are different, like different eyepiece and objective designs and optically different focusing systems.
