    Zeiss Gavia 85 Review

    The price of the 883 with the 25-60x has increased since that review. I see the B&H price is $3150 today. I'd check out the Nikon 82mm Monarch at about $1600. I still don't know for sure whether it's a re-issue of the old 82ED Fieldscope. If it is, a good sample should be superior to the...

Joachim, I'm only offering a downgrade of the ED glass as a plausible explanation for the color in Gavia since Kamakura demonstrated with the ICON that this objective design can do better, but it's purely conjecture on my part. I don't know what glass is in any of...

    Zeiss Gavia 85 Review

    I borrowed a Zeiss Gavia 85 for a couple of days last week with the idea of writing a review. Two days turned out to be too little time to get around to checking out everything, so here are the results of the tests I had time to do.
