The. KENKO LENS2SCOPE adapter is an accessory that can change any lens into a spotting scope. The LENS2SCOPE adapter's light-weight composite body houses a high quality roof prism optics and an eyepiece just like a traditional spotting scope. When the lens is attached it becomes a spotting scope to use for viewing. The lens mount and housing for the optics are made from metal while some external barrels are polycarbonate. The optics in the LENS2SCOPE magnify the image by a factor of 10x so that a 100mm lens would have the same magnification as a 1 000mm lens when viewing. Focus is easily achieved by using the lens' manual focus ring. It has a removable tripod adapter for mounting onto a tripod for more comfortable viewing for extended periods of time. This small accessory comes with its own carrying case and takes up about as much room in a camera bag as a normal lens.
. The PF-65EDA II Scope with 20-60x Zoom Eyepiece is designed for high-precision outdoor viewing and has now been improved over its predecessor by further minimizing color aberrations resulting in truer colors. These scopes use 1.25' diameter eyepieces which allow less compacting of the light shaft produced by the objective lens and thus a larger image with superior depth perception. This is a great feature for in addition to the brilliant offerings from Pentax themselves it also means you can use the best of astronomy eyepieces from elite telescope manufacturers such as Meade Celestron and of course the venerable Tele Vues. The PF-65ED II has a focal length of 390mm so if you're using conventional 1.25' eyepieces you divide 390mm by the focal length of your eyepiece to determine the effective magnification. Pentax ED scopes function brilliantly in many conditions of light and climate and are remarkably light thanks to their metallic alloy housing.
. The compact lightweight and ruggedly constructed Fieldscope III series features loaded o-ring seals and nitrogen gas for waterproof and fog-free operation. This results in more light transmission compared to previous models and enables extra-bright viewing.In addition to straight body types feature angled body types making sketching and extended viewing much easier. this model can be turned up to 90 degree right and left and lock in five positions (90 and 45 degree right and left and normal).
. Remarkably compact and lightweight this Fieldscope also provide superior waterproof reliability. Fully compatible with nine conventional Nikon Fieldscope eyepieces. This Fieldscope is designed primarily for birdwatching and digiscoping applications. Nikon Fieldscope ED50 Series feature highlights Compact lightweight and portable with objective diameter of 50mm Easy-to-use entry models effective for digiscoping Extra-low dispersion (ED) glass employed for objective lens Fully multilayer-coated lenses Straight and angled body types available Nitrogen-filled waterproof construction Built-in screw to attach filter.
