Objective Lens Diameter: 65mm
I picked up a few more Swarovski components including the 65mm lens for travel. I have used it with my ATX and BTX eyepieces and it may be small, but oh so mighty! I have set it up for family events and plan to use it when we travel. The image is so sharp and crisp. It doesn't compare to my 115mm lens in low light conditions, but I never expected it to. But in daylight it is absolutely phenomenal. Highly recommended for back country hunts or to watch birds and game when traveling!
