The Schneider 138mm Split-Field Diopter Lens shortens the close-focusing distance of normal fixed focal length or zoom lenses. This allows the camera to focus closer to the subject and achieve a larger image size while bringing out the sharpest details in even the tiniest subjects.
Diopters are the simplest and least expensive method of close-up photography. Have you ever wished that your lens could focus closer than it does? Imagine that you could put a magnifying glass in front of your camera's lens. With Schneider Diopters, you can dive into the world of macrophotography with a minimum of expense and with a maximum of confidence.
Shoot your stamps, flowers in your garden, your jewelry collection and many other items. If you're thinking of insuring your collectibles, why not have a means of doing it without having to hire an expensive pro? Close-up lenses not only give you creative freedom to help show you a world up close that you never imagined, but also serve as a functional and valuable tool to safeguard your possessions.
Split-Field Diopters are the ultimate tool to enhance depth of field. Diopters permit more of the scene to be in total focus simultaneously. Split-Field lenses are often used to increase depth of field in pictures shot with anamorphic lenses.
Split-Field diopters are semi-circular, single element close-up lenses mounted in a precision crafted metal ring.
To prevent the optical element from rattling or coming loose, Schneider first fits the glass to the mount with great precision and then locks it firmly in place with a state-of-the-art sealant.
- Made from Water White glass with anti-reflective (AR) coating on both front and rear surfaces; reduces light loss and flare and ensures proper color, contrast and overall image sharpness
- Screw-on versions are supplied with brass mounting rings while drop-ins feature anodized aluminum rings
- These lenses can be used individually or in any combination to achieve ultra-close focus
- The maximum magnification achieved with these attachments will depend on the focal length of your lens as well as the actual close focusing capability of that particular lens
- A +1 close-up lens will allow you to focus your lens somewhat closer than it already does; A +2 close-up lens will allow you to focus closer than the +1; A +4 lens will allow you to focus even closer than a +2
- A +1 combined with a +2 will equal a +3, while a +2 combined with a +4 will equal a +6, and so on
Note: They are available in different "powers" (diopters)
