This Deluxe Adapter kit is used to connect Nikon DSLRs to most Telescopes accepting 1.25 Eyepieces. Included in this kit: Our Deluxe Variable Eyepiece Projection adapter , a Prime Focus adapter, a T-Ring to fit Nikon DSLRs, a Parfocalizing ring and basic setup instructions. The Variable feature lets you adjust the adapter length to vary the magnification (thus image size) for perfect framing of your shots. The Parfocalizing Ring lets you to match the focus of a spare eyepiece with your Camera setup for easier focusing. Fits most Plossl eyepieces up to 26mm FL (max 1.5 Upper Body Diameter). Fits all Nikon Film or Digital SLR Cameras including: D1, D2, D3, D3S, D3X, D35, D4, D40, D40X, D50, D60, D70, D80, D90, D100, D200, D300, D300S, D600, D700, D750, D800, D800E, D810, D3000, D3100, D3200, D5000, D5100, D5200, D7000, D7100, etc. Does not fit the small Nikon “1” Mirrorless cameras. IMPORTANT NOTES: Not intended for Spotting Scopes. This unit is for astronomical type telescopes that accept standardized 1.25 (lower barrel diameter) slip-in type eyepieces. Additional parts may be required depending on telescope type. Reflectors typically require a Barlow Lens to be placed between the adapter and focuser to extend the focus point. Refractors typically require you to replace the Diagonal with a slightly shorter extension tube to reach focus. This is true of ANY adapter. Most SCTs and Maks won't require anything else. Assembled unit with T-Ring weighs ~8.8oz (without eyepiece and camera). Pictures shown are representative of the product line. There may be small differences depending on the model of your camera or incremental improvements to the item. Not compatible with ETX 60/70/80 telescopes due to lack of back focus. Not recommended for Reflectors smaller than 4, Refractors smaller than 60mm or Catadioptrics smaller than 90mm. |

This Lens Mount Adapter from Viltrox allows a F-Mount, D or G-Type lens to be mounted onto a Micro Four Thirds camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a one-stop increase for the camera over the lens's aperture range. If a lens intended for larger camera sensors is connected to a Micro Four Thirds camera, it would project an image larger than the camera's sensor was built to accept. Able to capture only the center portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera crop factor. This adapter condenses the light from an attached lens and projects it onto a Micro Four Thirds camera's sensor. This allows the camera sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional one stop of light for each of the lens's f/stop settings. This adapter supports manual focusing and eight stops of aperture control. It is constructed with five lens elements in four groups that are designed to provide optical clarity as well as color fidelity, and the underside of its removeable tripod foot is tapped with a 1/4-20 accessory thread, enabling direct attachment to a tripod or quick release plate that feature 1/4-20 mounts.

The 1.25 Variable Universal Camera Adapters allow attachment of a camera body to reflector and refractor telescopes for either prime-focus or telescope eyepiece-projection photography (hence the term universal). The adapter slides into the eyepiece holder as an eyepiece normally would. This universal adapter is composed of two detachable parts: a prime-focus adapter (or T-adapter) for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography. A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a sliding barrel design that allows variable projection distances. This allows for slight changes in magnification without swapping telescope eyepieces when performing eyepiece-projection photography. Fits reflector and refractor telescopes with 1.25 eyepiece holders. This Variable-Power Universal Camera Adapter is precision made of black-anodized aluminum and is compatible with 1.25 telescope focusers and many 1.25 telescope eyepieces (some eyepieces have housing diameters that are too large to fit inside the adapter). The barrel of the adapter is threaded for filters. A T-ring for your specific camera model (sold separately) is required to couple your camera body to the universal adapter. |
