Zoom-lenses in general are not really famous for high quality optics. Also many zoom-eyepieces do not deliver the best possible image quality at high magnification because they were designed with focus on the price-tag so that image sharpness and field size is getting worse with increased magnification.
The recognition that the Hyperion Zoom Eyepiece enjoys is based on the fact that it was designed the other way around: the glass selection and most of all the principal optical design and consequently the lens polish quality – all were optimized for the highest magnification. And obviously, when closing in on an object you will want the field of view to increase and not to have it become seemingly smaller. Hence the Hyperion-Zoom shows the largest apparent field of view at highest magnification.
For many birders, observers of nature and astronomers alike, the Hyperion Zoom Eyepiece is their favorite eyepiece, it is also the only zoom-eyepiece that was designed from ground up to be used with bino-viewers.
What's new in the model "Universal Zoom Mark IV"?
Even Bestsellers can be improved: The fourth generation of this eyepiece weighs 290 gram and is lighter by 80 grams than its predecessor - it now has 55 mm diameter to become useful in dual mode from 55 mm interpupillary distance, both features make it especially desirable for use with bino-viewers. The adjustable eyecup can be removed to expose the M43 video/photo thread and create the maximum "nose space" for using it on binocular viewers with the supplied winged rubber eyecups - for maximum concentration on the target. The click-stop action has been smoothed out to more easily access the magnification stops at 8/12/16/20 and 24mm (click-stops are mandatory to easily and precisely set both eyepieces to the same focal length for effortless binocular observation without eye-strain). The zooming-mechanism as well as the inner zooming rails for all lens groups have been modified to improve cold temperature operation and the parfocalty for each focal length has been finetuned.
Most important however – the Mark IV offers almost 4 mm more backfocus. This is most beneficial for application with a multitude of spotting scopes. Two different Adapters for telescope and spotting scope adaptation are included with the eyepiece (Spotting-Scope Adapter „A“ and Telescope-Adapter „B“). Read more at "Telescope-sided Connections").
The Mark IV comes with both the 2" and 1¼" nosepieces mounted, each nosepiece having it´s own dust cap and both nosepieces are threaded to accept either 1¼" or 2" eyepiece filters. Both nosepieces are free of the hated undercuts. Instead our proprietary Zero-Tilt Safety-Kerfs provide an added measure of security by reducing the tendency of an eyepiece to slip from an unlocked eyepiece clamp.
An additional little feature is the Baader-yellow soft pouch with integrated belt strap – which fastens onto many tripod legs just as well, to serve as a bin for all dustcaps that may go astray otherwise.
