Opticron's best variable magnification eyepieces for spotting scope.
Top quality lenses and mechanics, hence a higher price. SDLv3 has been improved with more lenses and optimized for Opticron's binoculars compared to its predecessors SDLv1 and SDLv2. Now hardly any focusing is required when going from one degree of magnification to another. SDLv3 provides, among other things, a better field of view than its predecessors and, for example, the HDF zoom, and is therefore somewhat better suited for glasses wearers. Supplied in a soft case with belt clip. Note that this zoom eyepiece is waterproof, for example HDF T zoom is not.
