Ideal for multipurpose applications that need both close focus and wide fields of view. The lenses offer variable apertures, to adjust the depth of field. Filter threading allows the use of filters to adjust incoming light levels with ND filters, or increase contrast with color filters on monochrome sensors, and more. Economical and compact, these lenses have many features that make them a perfect choice for a variety of uses.
Note: #58-240 Close Focus Zoom Lens can be used for working distances from 127mm to infinity, where its field of view would be 8 - 48mm (horizontal for 2/3" sensors) at minimum working distance.
