Key Features
  • • 1.4x magnification

  • • Index-marked adjustable back focus for optimal lens performance

Compatible with all Orion Series Lenses 21mm - 100mm, as well as a variety of other zooms and primes.

To confirm whether our 1.4x Expander 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 1.4x Expander. 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 1.4x Expander, please email for assistance.

Equivalent Focal Lengths

When using the LF Expander with our Orion Series:

• Orion 21mm + 1.4x expander = ~29mm
• Orion 25mm + 1.4x expander = ~35mm
• Orion 32mm + 1.4x expander = ~45mm
• Orion 40mm + 1.4x expander = ~56mm
• Orion 50mm + 1.4x expander = ~70mm
• Orion 65mm + 1.4x expander = ~91mm
• Orion 80mm + 1.4x expander = ~112mm
• Orion 100mm + 1.4x expander = ~140mm

The 1.4x LF Expander allows our Orion Series lenses to cover Full Frame (36mmx24mm) sensors with full anamorphic coverage and with light loss of only 1 stop. We include a handy check gauge with each expander to help you ensure the rear element/cone of the lens will not interfere with the expander optics.

If used with 35mm format (non FF/LF sensor), it extends your lenses by 1.4x (100 becomes 140, 80 becomes 112, etc.)

Optimized for Atlas Orion Series lenses but compatible with other lenses as well.

For more coverage options, please check out the Atlas 1.6x LF Extender.
