The TSN-DA10 adapter is perfect for combining compact and lightweight camera systems, such as MFT or mirrorless system cameras with or without a lens, with the eyepiece. If the lens is also to be used to access camera functions, the focal length must not exceed 50 mm (based on 35 mm). The adapter is designed for our premium spotting scope series TSN-99/88/880/770 in conjunction with an eyepiece TE-11WZ, TE-80XW, or TE-10Z. Kowa believes that digiscoping should be simple and affordable. The TSN-DA10 adapter meets both criteria. Attaching it can be done in no time. Unscrew the eyecup and attach the inner ring of the TSN-DA10 adapter to the now exposed thread. The outer ring of the TSN-DA10 adapter is secured to the filter thread of the lens using an additional adapter ring available from our accessory program (available in sizes: 28 mm, 30 mm, 30.5 mm, 37 mm, 43 mm, 46 mm, 52 mm, 55 mm, 58 mm, 62 mm, and 72 mm). Now you can slide this combination (camera + lens + DA10 outer ring) over the inner ring and secure it with the knurled screw. You can now create high-quality telephoto shots and videos, venturing into focal lengths that no conventional camera lens can reach, while the equipment remains even lighter and more compact.
