Large Format Lenses Provide Twice the Light Throughput
TECHSPEC High Resolution Large Format Lenses offer a maximum aperture of F4, which provides twice the amount of light throughput of comparable lenses at F5.6. These large format lenses are designed to reduce chromatic aberrations while yielding stunning sharpness and contrast, even at maximum aperture. They are offered in seven standard lens options at nominal magnification values of 0.33 to 3.0x, with superior performance extending over a range around these magnification values. The lens cell features a locking variable iris and front filter threading for ease of use. Several focusing and mounting options are available to accommodate most camera interfaces for many of the magnification options.
