Sigma Lens Purchase Advice: 50-500 or 150-500
I switched over to the D700 from a Canon 40D. I purchased and own a Sigma 150-500 for the Canon and will be selling it to purchase one for my D700.
The questions are based on whether either of these lenses are going to be compareable w/ the full frame sensor and the pros/cons of the 50-500 vs. 150-500.
What I do know is the 50-500 does not have VR and the 150-500 does. Conversely the 50-500 is 4-6.3 and the 150-500 is about 2/3 less, at 5-6.3.
I like the idea of having a wider range and wider aperture...
Any other ideas or input on the two lenses.

Beware that the 50-500 at least has considerable vignetting in the corners of FX. I have no experience with the 150-500 but I'd be very surprised if it's significantly better in this regard. On the Bigma, the vignetting is drastically better stopping down only to f/8. All this is at 500mm - I don't use the Bigma much at any other focal length on FX.
The Bigma is not significantly different in aperture, and in fact I think it's slightly slower. The 50-500 is f/4 but only at 50mm - it's f/5.6 by a bit longer than 100mm, so at 150mm it's probably a third of a stop slower. I'd guess that by 200mm they're both f/5.6, and of course they're both f/6.3 at 500mm.
As noted, I personally don't use the Bigma at focal lengths much less than 350mm on FX, and the vast majority of the frames are at the full 500mm. I used 300mm or so on DX a moderate amount - but that's the equivalent of 450mm on FX. I hardly ever used less than 300mm, even on DX. (But then again, I have lots of lenses that cover 200mm, most more effectively than the Bigma does.)
