Update: BuyDig has this lens for $149 once you add it to your cart ($26 cheaper than B&H).
A reader sent me a link to this, apparently new, Rokinon 7.5mm f/8 RMC fisheye lens for Nikon 1 mount. I do not remember seeing an announcement for this lens. Anyway, here is some additional info from B&H website:
- Nikon 1 Mount Lens/CX Format
- Fixed Aperture: f/8.0
- 20.25mm (35mm Equivalent)
- Expansive 162° Angle of View
- Seven-Layer RMC Multi-Coating
- Manual Focus Design
- Built-In Petal Type Lens Hood
- Aluminum Alloy Lens Barrel
"Rendering a unique perspective for creative applications, the 7.5mm f/8.0 RMC Fisheye Lens from Rokinon is a manual focus prime featuring an expansive 162° diagonal angle of view. Benefitting the fisheye perspective of the lens is a 7-layer Rokinon Multi-Coating (RMC), along with a built-in petal type lens hood, which helps to minimize surface reflections and lens flare for greater image contrast and color fidelity in a broad array of lighting conditions. Further emphasizing the perspective-altering attributes of the lens is an 11.8" minimum focusing distance, which pairs with the manual focus design to help in accentuating foreground subject matter and emphasizing a unique sense of space.
This lens is dedicated to Nikon 1-series CX-format mirrorless digital cameras, and provides a 35mm-equivalent focal length of 20.25mm. It features an all-glass four-element-in-four-group construction, and is housed within a durable aluminum alloy lens barrel with rubberized focusing ring.
