The MaxView line of digital camera eyepieces have the proper focal point for use with cameras that have non-removable lenses. With the introduction of inexpensive SLR type digital cameras many people want to use the MaxView eyepiece with their SLRs. Some spotters such as the Swarovski and Pentax generally have enough focus range to work well as-is. Some others with a more limited focus range require an extension tube to be added between the MaxView optical element and the scope adapter. The extension simply screws on and instructions are included. |
