    Comments about Pentax 1/2" C Mount 8-48mm f/1.0 Manual Zoom Lens:

    Purchased for use with Mallincam Xtreme astro-video camera; however, the quality of chip to mounting flange backspace on the Mallincam is not great, i.e.: the Pentax lens would not come to focus w/ or w/o a 5mm spacer until I trimmed 0.5mm off the spacer. Works just fine now!

      Comments about Pentax 1/2" C Mount 8-48mm f/1.0 Manual Zoom Lens:

      I use this lens on machinevision camera's (Basler Pilot series) as an allrounder in sports research. Compared to other lenses I used it's very "lightstrong" with its f1.0. The 6x zoomrange makes it possible to optimally frame the image so that all pixels are used, independently from cameraposition. In pilot research I use this lens to determine the focal length for the lens used in the permanent setup. This lens is excellent in contrast, color saturation, sharpness and little distortion.
