With the Opticron MM4 50 GA ED spectrophotometers, the factory's new generation of instruments has put the emphasis on smaller size, brighter, brighter and sharper imaging while maintaining the traditionally reliable, sophisticated design. The straight and 45% versions of the Opticron MM4 50 GA ED are an ideal choice for sport shooters, archers for target practice or simply for viewing the surrounding panorama and birdlife from the balcony.
As with most higher-end brands, the scope does not have an included zoom eyepiece, so that the user can take possession with the type of eyepiece that best suits their needs. The manufacturer recommends the Opticron HR, HDF, SDLv2 eyepieces, so that either zoom or fix magnification can be achieved. Where the magnification range of binoculars ends, the time for Opticron spectra comes. When placed on a tripod, they allow long and comfortable observation over the full magnification range. Thanks to its high quality multi-layer FMC coatings, the binocular's light utilisation is higher contrast, brighter and more colour-fidelity than cheaper instruments, and its apochromatic lens replacement system ensures high quality imaging free of chromatic aberration.
The British company Opticron manufactures its ED spectra in their Japanese factory, resulting in reliable, high quality products.
The Opticron MM4 50 GA ED spectroscope iswaterproof, so there is no need to worry about condensation leaking inside the tube. Its 45-degree-viewing version is recommended for both horizontal and upward viewing, and its straight-viewing version is a favorite of sport shooters and hunters, for example. Thanks to its short (2.5 m) closest point, it also allows us to observe at shorter distances, which is useful for observing small, shy creatures and birdwatchers.
For added convenience, the tube can be rotated 360 degrees in its tripod ring and positioned every 45 degrees around its longitudinal axis. Of particular note is the two-speed (8:1) microfocus focusing eyepiece for very precise focusing. An optional photo adapter is also available, allowing you to shoot with SLR cameras.
TIP: The MM4 50 Spectra can be used with a photo adapter to match a telephoto lens with a 530mm F10.6 aperture.
