[QUOTE="338Shooter, post: 1604698, member: 3449"] I'm sorry you don't understand optics. If you start with a single lens, the larger diameter the lower the magnification and the larger the FOV. To increase magnification you reduce the lens diameter reducing the FOV. To combat this, you can stack lenses to allow you to use larger diameter lenses to keep or increase the FOF while achieving the desired magnification. The down side to this is optical quality degrades when the number of lenses increases. This leads to a need for higher quality glass which can be very expensive. However, many 30mm scopes out are only thicker tubes with lenses that would fit in a thinner 1" tube. [/QUOTE]
