Super-telephoto mirror lens for Fujifilm X
This 500mm f/8 reflex lens uses a catadioptric optical design to reach distant subjects while staying compact. It is built for photographers who need long reach on Fujifilm X-mount cameras without the bulk of conventional telephoto optics. The fixed F8 aperture suits bright outdoor scenes such as wildlife, landscape and astrophotography. Manual focus operation appeals to shooters comfortable setting distance by hand.
Mirror construction and multi-coating
The reflex design folds the light path to keep the lens short and light at 10.93 oz. Multi-coating reduces reflections and glare to preserve contrast and colour fidelity. The characteristic donut-shaped bokeh adds a distinct look to out-of-focus highlights. A Fuji X standard mount with 42mm thread and 0.75mm pitch allows attachment via adapters to other systems if desired.
Fixed F8 aperture dictates use
The constant F8 aperture means exposure control relies on ISO and shutter speed alone. This makes the lens best suited to well-lit conditions or tripod-mounted long exposures. Photographers who need variable aperture for changing light or shallow depth-of-field control will find this design limiting. Autofocus is not available, so fast-moving subjects require practiced manual technique.

Questions about this item
Does the mirror inside the 500mm reflex lens ever need cleaning or replacement?
The fixed mirror assembly is sealed inside the barrel; normal use only requires wiping the front element and the rear glass surface.
What stops me from shooting longer than a few seconds at the fixed f/8 aperture?
The constant f/8 aperture cannot be opened wider, so exposure time is limited by available light and the camera’s ISO range.
How much heat or noise does the 10.93 oz lens produce during all-day wildlife sessions?
With no motor, stabiliser or electronics, the lens generates no audible noise and no measurable heat during continuous use.
