Which Zeiss Victory FL would you buy, the 10x42 or 7x42 Victory?
The 7x42 will be brighter in low light and have a wider field of view. As you increase magnification things appear larger, but there are a few compromises. Another is that the 10x will be less easy to hold steady versus the 7x. If these two were my only choices, I'd probably go with the 7x because I place more of a premium on field of view and brightness.
