Compact Telephoto Lens A full 500 mm lens of less than 9 cm overall length turns every camera into a secret tele-specialist. The long focal length is achieved by using mirrors in the beam path, a technology that has long been used in telescopes.
Strong macro With a close-up limit of 1.72 meters, the lens can also take macro shots between 1:4.3 and 1:2.87.
Mirror lens technology The incoming light is reflected back towards the front of the lens by a concave mirror, then from there back through the center of the concave mirror by a secondary mirror, on through the lenses located there and finally onto the sensor of the camera. Basically the same technology as in the Hubble telescope.
Universal aperture f/8 and two filter threads Due to the design an iris is not usable here, the aperture is therefore fixed at f8.0. The brightness is determined by the choice of the exposure time. Filters with 30.5 mm can also be screwed in front of the rear opening of the lens to change the exposure characteristics. However, they do not influence the flange focal distance or the T2 adapter. Three filters are included with the lens, 1x Skylight, 1x ND 2x (-1 aperture) and 1x ND 4x (-2 apertures). On top of that, filters with a thread of 72mm can be attached to the front side of the lens.
Low chromatic aberration, unique Bokeh A big advantage of this type of construction is its extremely low chromatic aberration. In the Bokeh, highlights always produce small rings - your images will definitely be unmistakable. The lens is also well suited for photography of the moon, and, with protective film, also for the sun.
Connects to any camera thanks to T2 The lens has a T2 thread. Connection to the camera is made through a separately available adapter. The focal length changes according to the crop factor of the respective camera. The focus is controlled manually.
