The LF Extender is optimized to give superior optical performance with our lenses even wide open, with only 1.3 stop light loss. We include a handy check gauge with each extender to help you ensure the rear element/cone of the lens will not interfere with the extender optics.
If used with 35mm format (non FF/LF sensor), it extends your lenses by 1.6x (100 becomes 160, 80 becomes 127, etc.)
See how our LF Extender looks when paired with the Orion Series on the Alexa LF Mini.
- 1.6x magnification
- 1 and 1/3 stop light loss
- Includes clearance check gauge for rear element
- Not compatible with EF mount
To confirm whether our LF Extender is compatible with your lens, use this Atlas printable clearance check gauge. If your lens’ rear element clears the gauge, your lens should work with our LF Extender. However, physical fitment does not guarantee perfect optical performance, which is dependent on the optical design of your lens.
If you’re unsure if your lens will work with our LF Extender, please email email@example.com for assistance.
