Manufacturer description
The medium format teleconverter MC HARTBLEI 2x has been designed for the professional photographers. Each converter is hand assembled and carefully checked. Converter has a metal housing, no plastics are used. The six-lens optical system is multi-coated (MC) and has anti-reflection surfaces on the lenses, which improve the quality of the image and increase its contrast range due to the increased integrated light transmission. Each lens element is ground and polished with meticulous care to exacting tolerances and covered by a special multilayer coating to reduce internal reflections, increase transmission efficiency and enhance contrast. Resulting photographic images are of breathtaking quality, exquisite in their definition, luminance and color fidelity.
The converter increases a focal length of a lens by 2 times, which greatly expands shooting features of your camera. Having normal 80mm lens and only one additional lens, you become the owner of four lenses. Resolution of a lens with the converter decreases very slightly. Lens remains coupled with camera, as converter has aperture pin.
Effective aperture is a two-stop lower for the lens / converter pair. Normal 80mm / f=2.8 lens becomes 160mm / f=5.6 lens with 2x teleconverter, therefore if you use external light-meter, it is necessary to make appropriate correction in the light-meter settings.
