In answer to the poster regarding the other 3 brands:
1) Zeiss, no question it's a better scope than the Leo & I own several Leo's and only one Zeiss, but it beats all the Leo's I have. The Conquest gives a clear edge in brightness.
2) Leo is better than Nikon IMO by a larger margin than the Zeiss has over the Leo.
3. Nikon, not bad glass, but not up to the first two. I also am not a fan of the Nikoplex with the little circles.
