The Sofra Astroscope 9350SCOPE-3PRO Night Vision Pocketscope provides matchless versatility and comes complete with a 50mm f1.3 C-Mount Lens and a Generation 3 image intensifier tube. Use a standard C-mount lens or attach the Front Lens Adapter (FLA) from an AstroScope 9350EOS-P system designed for use with a Canon SLR camera or an AstroScope 9350NIKS-P designed for use with a Nikon SLR camera and use your existing high-performance objective lenses. This feature is particularly useful for long range, low-light applications. Most pocketscopes are designed for short range, wide angle viewing. If you already own a high quality long lens (for example, something like a 70-200mm F2.8), attach it to the 9350SCOPE for unparalleled performance! Front Objective Lens and Image Intensifier not included.
