An F24 - F8, 5-group 8-element 'super' zoom, the 40935 SDL has been designed to maximise the performance gains inherent in Opticron ED objective lens fieldscopes at higher magnifications. Offering an optimum ratio between field of view and resolution, the main viewing characteristics of the SDL eyepiece are superior cross-field definition at all magnifications, coupled with exceptional viewing comfort. Mechanically, the eyepiece is waterproof, uses the M41.5 collar thread attachment, features a 90° rotation between high and low magnification settings plus a rotating, retractable twist-type eyecup assembly, that can be positioned to match individual needs.

Supplied in soft padded case.
