Bigger objectives and a matching bigger prism if you want to keep the same FOV would bump the weight. They mitigate this in the 10x by not needing to bump the prism size (and deal with a smaller FOV in the 10x).And to keep the same f/number of the objectives you would need to make the focal length 25% longer making the bins a bit under 25% longer. Do they do this in the 10x? Or does the 10x have slightly worse CA properties?Like most companies Zeiss doesn't want to muddy the waters by adding a model slightly similar to the others so it makes the smallest bin people want and if they don't like that one they can move up to an 8x30 or 8x32.</blockquote>
