The following is an email response from Leupold concerning the VX-III. This was posted on another BB that I frequent.
"For 2004, Leupold introduces the VX-III line of Golden Ring Riflescopes. The VX-III carries many of the great classic features of the tried and true Vari-X III line but with several exciting new features. Based on the superior optical design of the Vari-X III, the VX-III delivers even more light transmission with The New Index Matched Lens System. No longer are tools required for making windage and elevation adjustments as we introduce the new, highly precise Finger Adjustable Elevation and Windage. Reticle focus will be faster and easier now with The Lockable Fast Focus Eyepiece. More Long Range models are now available.
The VX-III 1.5-5x20mm and 1.75-6x32mm are top choices in dangerous game and quick pointing optics with wide field of view and now an even brighter image for dark, shadowed woods. The VX-III 2.5-8x36mm, 3.5-10x40mm and the 4.5-14x40mm fixed objective all meet the needs of the serious hunter who needs an excellent combination of low power, wide field of view and higher magnification for longer range shots, all in a package that fits well in a scabbard. The VX-III 3.5-10x50mm fixed objective provides the best low light performance while the VX-III 4.5-14x50mm Long Range gives both great low light performance for deep timber and is equipped for long range shooting of open country with side focus and generous adjustment travel. The VX-III 4.5-14x40mm Long Range, 6.5-20x50mm Long Range (also available in a Target model) and the 8.5-25x50mm Long Range Target meet the needs of shooters that demand maximum capabilities for placing shots accurately in a wide range of conditions.
In addition to the full array of Leupold reticles, the VX-III riflescope family now also features the new Leupold Wide Duplex reticle (available in Spring 2004) in addition to the New Ballistic Reticle System: The Boone and Crockett Club Reticle for big game and the Varmint Hunter's Reticle. The Leupold Index Matched Lens System provides the best light management across the entire image, maximizing contrast and image brightness, delivering as high as 98% light transmission. New Finger Adjustable Windage and Elevation Dials make sighting in easy and zero can be reset by moving the golden pointer ring. Except for the diopter directional markings, The Lockable Fast Focus Eyepiece still carries the Leupold Classic look but focuses 4 times faster than did the Vari-X III, then can be locked in place when best focus is achieved. The Long Range configuration of Side Focus for parallax correction and 30mm maintube for added elevation adjustment travel has been carried through to all models of 4.5-14 power range and higher to provide easy to operate parallax correction and expanded capability to achieve longer range shots.
Leupold's new VX-III riflescopes are manufactured at the Leupold Beaverton, Oregon factory and are backed by the Leupold Full Lifetime Guarantee."
