LRF-Wise, the sigs make my geovids look sick. The glass is definitely a lot better in the leicas though.
That being said the glass in my 8x32 sigs is plenty serviceable for my needs
What are the distance ratings of the Sig and Geovid you're comparing?
Jordan,
It may not be a fair comparison because my sigs are 6k rated and my leicas are 2k. I notice a difference a lot closer though.
The leicas do well in good conditions out to 900-1000 yards for me, though they are noticeably slower than the sigs. Past 1k the sigs pull away.
The big difference I see is that the sigs are a lot better in bad conditions, as Stick said. A foggy or hazy day really makes the sigs stand out to me.
