Zeiss Introduces Magnum Riflescope

Victory Diavari 6-24x72 Delivers Maximum Performance for Long-Range Shooting

CHESTER, Va., June 13, 2005 – Carl Zeiss Sports Optics is bringing a magnum-sized riflescope to the American market that has previously been available only to European military and law enforcement agencies.   The 72mm objective lens of the Victory Diavari 6-24 riflescope provides enhanced light transmission resulting in increased brightness and resolution that enables the shooter to locate and identify targets at extreme distances in very low light conditions.  

Built for the professional marksman, this state-of-the-art riflescope features a 34mm tube to provide a wider range of adjustment and additional strength that makes it an ideal scope for high-powered rifles chambered in calibers such as the .50 caliber, .408 CheyTac and .338 Lapua.    Hunters who shoot at long distances will especially appreciate the increased detail seen through this scope, which permits extremely accurate aiming before firing, thanks to the exceptional light transmitting ability of the 72mm objective and the large exit pupil.  

What is exit pupil (EP) and why does this matter?   The amount of light that actually makes it through the

eyepiece to the eye (EP in mm) depends upon the objective size and magnification.  At 6x, the exit pupil is

12mm (objective size ÷power or, in this case, 72 ÷6 = 12).  While it is true that the pupil aperture of the human eye at its best, depending on age, is a maximum of 7mm, this extra light is not totally wasted.  An advantage with the 6-24x72 is that the large exit pupil is much more forgiving as far as head placement is concerned.  If you aim quickly and are not aligned perfectly so that you are looking into the middle of the eyepiece, the field of view remains constant thanks to the oversized exit pupil.

The greatest benefits of this 72 mm objective lens, however, are seen during twilight hours.  With the magnification set at 10x, the EP diameter is 7.2mm resulting in 100% light transmission to the naked eye of those up to an age of 35 or 40 years old.  (With age, the pupil aperture of the human eye decreases.) So, at 10x, this is a twilight performance as yet unheard of – ideal for shooting in the most adverse low-light conditions.  

Comparison of the 6-24x56 vs. the 6-24x72:

At 10x, the 56 mm objective has an exit pupil of approximately 5.6 mm.  An almost equally large EP is featured in the new Victory Diavari with the 72 mm objective lens with 13x magnification.  This 72 mm scope produces increased image brightness and detail with increased magnification.  So, the advantage for the hunters with pupil apertures between 5 and 6 mm, due to age, is that they will see a brighter image with the 72 mm objective lens at 13x magnification than they will with the 56 mm objective lens at 10x magnification even though the EP of both riflescopes is practically the same.  Binoculars and riflescopes with an EP of not less than 4 mm still rank among the hunting optics models suitable for use in the twilight hours.  This EP is achieved at a whopping 18x magnification with the Diavari 6-24x72.

Illuminated reticles are a standard feature of Victory Diavari 6-24x72 and are available in three options - #40, #43 Mil Dot and #63 Mil Dot (see page 3). Additional standard features include fast and accurate reticle adjustments (elevation of 63 inches and windage of 27.5 inches at 109 yards) and a turret mounted adjustable parallax with which even image sharpness can be adjusted at high magnification levels.   The reticle is located in the second image plane and, therefore, does not magn
