The Kowa TSN-VA3 14x High Resolution Video Camera Adapter is a cutting edge improvement in the world of digiscoping products. It practically makes shooting with an SLR alone with telephoto lens useless.
The TSN-VA3 is a big chunk of glass and metal that attaches to your 88mm or 77mm series spotting scope just like an eyepiece. You could actually observe with it right then, as a 14x lens, but it is intended that you attach a Kowa adapter ring to the rear which matches the filter threads on whatever you're putting behind the TSN-VA3.
The TSN-VA3 will allow you to use your SLR camera with its attached lens, and most would choose either a standard fast 50mm lens or a short telephoto such as an 85mm f/1.8 or 100mm f/2.0, etc. Your SLR lens doesn't do the focusing, so if you're buying a lens just for this task don't consider the focusing speed as it relates to digiscoping; all that matters is the optical quality, maximum aperture, and peripheral brightness at maximum aperture. With a maximum clear light-gathering aperture of 88mm and the potential to capture that light at f/2.0 or f/1.4, the TSN-VA3 with 88mm scopes presents a serious competitor to a 600mm f/4, 500mm f/4, or 400mm f/2.8 lens so favored today in professional birding imaging.
- Enormous ~58mm-wide clear aperture assures no vignetting, even when using an SLR attached with a fast 50mm f/1.4 standard lens
- 14x Magnification with 3.0° true field (42° apparent field of view)
- Optical magnification equivalent to ~605mm lens (when used with a 24 x 36mm SLR + 50mm lens attached)
- Can be used with zoom and fixed telephoto SLR lenses for higher magnification and focal length
- Extremely long 60mm eye relief
