Compared to what? That is the ultimate question. 99.9% of the scopes out there will loose some percentage of clarity, light transmittion as you get higher. Comparing the conquest to the Fullfeild is apples to oranges. Zeiss makes quality, even in their low end scopes. The lenses in their "budget" line are Japanese, which does not make them bad.
I've had great success w/ Sightron scopes. The Big Sky series are really impressive. When I bought an SII 3-12x42mmAO I brought it to the range. It really pissed off my buddy using a Leupold markIII. Mine was much nicer w/ an equal guarentee at 1/2 the price at the time. I put an SII big sky 6.5-20x42mmAO for my .223 HB, it is outstanding.
