Reflex mirror lens
Ultra Multi Coating (UMC) of Samyang Optics
Samyang 7748 (SMY-7748, SMY/7748, SMY 7748, SMY_7748, smy-7748) 300mm f6.3 ED UMC CS Mirror Reflex Lens - Nikon F Mount
This smooth focusing manual focus lens weighs less than 300g and its long focal length makes it ideal for wildlife, landscape and astrophotography. As opposed to much heavier 300mm non-reflex lenses, this diminutive optic can be taken wherever you go. Please note that this lens is designed for cameras with APS-C sized sensors, not 35mm format.
Ultra Multi Coatings for the optical surfaces ensure that flare and ghosting are minimised, and the lenses themselves feature advanced glass. For example there is an ED (Extra Low Dispersio) lens for the “mirrorless camera” version of lens. The configuration is 8 elements in 8 groups for the DSLR version, and 9 elements in 9 groups for the mirrorless camera version. This arrangement gives excellent image quality due to effective reduction of aberrations.
Due to its extreme magnification, a good tripod and head are recommended, along with the combination of the use of a fast shutter speed, remote control and mirror lock-up where available, to obtain the best results. There are two filter options - a conventional 58mm front-mount and a 25.5mm rear mount.
