It won't be a true 600mm (even when focused at infinity).
On top of that, it will also have severe focus breathing at MFD, further (probably dramatically) reducing the focal length.
And aperture starts at f5! 150mm f5! Too slow, IMHO... F6.3 at 600mm is perfectly understandable, f5 at 150mm not so much.
And for $1500, quite honestly I don't expect good IQ from such a large zoom.
Of course, both variants of the sigma 50-500 have a reputation for good IQ (and it's a 10x zoom)... so we will see.
I don't have much expectations, though....
p.s.
I hope I'm wrong.
Well the Canon 100-400 is not a true 400mm either (385mm), and the Sigma 50/150-500 aren't true 500mm (465mm) lenses. The patent say 582mm, so that's pretty darn good for a cheap zoom.
