Ultra-Wide Fisheye for Fuji X APS-C
The Opteka 6.5mm f/2 is a manual-focus fisheye lens built for Fujifilm X-mount APS-C cameras. It delivers a diagonal angle of view of 190-degrees, creating a distinctive perspective with extreme deformation. Photographers and videographers seeking creative ultra-wide imagery for artistic, architectural or immersive video work will find this lens suitable. It is not for buyers who want autofocus, image stabilization or a rectilinear wide-angle view.
Bright Aperture and Close Focus
A maximum aperture of f/2.0 allows composition in lower light without relying on high ISO settings. The 9-blade diaphragm produces 18-point sunstars when stopped down toward the minimum f/22. Minimum focusing distance is 0.05m (1.9 inches), enabling sharp focus on subjects nearly touching the front glass. The lens has no electronic contacts, so exposure and focus are entirely manual.
All-Metal Build with 6-Element Optics
The barrel is constructed from metal for durability and precise handling. Optical construction uses 6 elements in 5 groups, including one SD super-low dispersion element to minimise chromatic aberration. High-definition anti-reflective coating suppresses flare and ghosting. The lens measures 2.25 x 2.5 x 2.25 in. and weighs .58 lb. It accepts no front filters due to the protruding fisheye element.

Questions about this item
How do I mount the Opteka 6.5mm f/2 on my Fuji X body and set the aperture?
Align the lens mount dots, twist until it clicks, then turn the aperture ring on the barrel to choose a value between f/2 and f/22; the camera will not control aperture electronically.
What upkeep does the all-metal barrel and 9-blade diaphragm need over time?
Wipe the front and rear glass with a microfibre cloth and blower; the manual aperture blades are dry-lubricated at the factory and require no user servicing.
At what point does the 190-degree fisheye projection limit usable framing for video?
The 190° diagonal view captures everything in front of the lens, so the operator’s hands or rig appear in shot unless the camera is held at arm’s length or mounted on a gimbal.
