The 40mm low power 1.25" E-Lux is a 3-element fully multicoated optical design (every air to glass surface is coated with several layers of high quality anti-reflective coatings).
The 1.25" E-Lux provides a wider field of view and longer eye relief than standard Plössls.
Only used once as I already had a Vixen LV50.
