New TTArtisan telephoto lenses

Coming soon TTArtisan telephoto lenses incl. 500 mm f/6.3 a 250 mm f/5.6 Reflex M42. The former will be especially pleasing to photographers and filmmakers working with nature or astronomical images and will be available for all common bayonets (E/Z/RF/L/X/GFX/EF/F). It will offer a solid metal body and, despite its low price, quality optics (8 elements in 5 groups) using two HR and two ED elements and multi-layer surface treatment; as well as toothed focusing and aperture rings and a detachable ring for tripod mounting (lens weight approx. 1564-1617 g depending on variant). The 250 mm f/5.6 Reflex is an unconventional catadioptric telephoto lens with a characteristically compact body and ring-shaped bokeh. It uses the M42 bayonet, and with an adapter it can also be used on Sony, Fujifilm, Canon, Nikon, etc.
