This Nisha 52mm Split Field Filter Photography Lens Accessoryincludes an aluminum-alloy filter ring that can mount onto a lens with 52mm front threads. Occupying half of the area within the filter ring is a close-up lens with a +2 strength diopter for use in achieving macro-like results. Close-up lenses are magnifiers that optically decrease the focal length of a camera lens they are placed on. This effect lessens the minimum focus distance between your camera lens and an object. Magnification can then be obtained while photographing an object by moving the front of the camera lens close to it. The magnifying power of a close-up lens is indicated by its diopter strength. A close-up lens with a higher diopter number provides more relative magnification and can be combined with other close-up lenses to increase or fine-tune its effect.

The other half of the area within the filter ring has no close-up lens element and is completely unobstructed, allowing a camera lens placed behind this filter to project an image where half of the frame is unmagnified. This provides the potential to place subjects magnified by the Nisha 52mm Split Field Filter within a discernible background, due to a close-up lens's secondary effect of only allowing a very shallow depth-of-field. The Nisha 52mm Split Field Filter can be effectively applied by lining up its close-up lens and the subject to be magnified with either the bottom or top front half as well as either the left or right half of the camera lens being used. The filter ring can then be rotated to orient the macro effect relative to horizon lines or specific background features. By also using a narrow aperture, the resulting wide depth of field can be captured by the remainder of the camera lens that is not affected by the filter's close-up lens. A foreground subject can then be magnified and simultaneously, some focus can be maintained on a background that would otherwise be rendered completely out of focus.

Q: 1. Is the black lens mount plastic or alloy?

A: The Nikon NIKKOR Z 40mm f/2 (SE) Len is built with a plastic mount.

Q: 2. It looks like the front element of the retro version is sticking out 1mm further than the regular S version : less vignetting ?

A: Yes, Nikon NIKKOR Z 40mm f/2 (SE) front element does not have a flat surface. However this lens was design for full frame cameras, and their is no vignetting problems in neither of the lenses.

Q: 3. Will this work on a zoom lens at minimum magnification? Or would I need a lens with fixed mm?

A: Will work with pretty much any lens but normal lens are considered to be lens with a focal length between 35mm to 50mm.

Q: 4. Will this work for a front-facing "selfie" camera on a smartphone?

A: The CAME-TV Smartphone Clamp with 52mm Filter and Lens Adapter, B&H # CAPHCLMP52MM, is designed to work with the main camera on a smartphone.

Q: 5. Does this exact lens need 'to 'pop-out' to be used. Is it a true 'pancake lens'?

A: Yes, the Nikon NIKKOR Z 40mm f/2 (SE) Lens has an internal focusing design.

Q: 6. Would this work on a Pixel 8 Pro with the camera bar?

A: Yes, the CAME-TV Smartphone Clamp with 52mm Filter and Lens Adapter, B&H # CAPHCLMP52MM, supports a smartphone like the Pixel 8 Pro. You would need to use the adjustment on the filter mount to line it up with the camera you want to use.

Q: 7. I own a Nikon D5500, which I understand does not have an optical low-pass filter. The product description for this filter indicates the camera requires a "conversion" to eliminate the low-pass filter. My question: will this filter work as intended without the "conversion" for the D5500? Thanks. Frank

A: No, to use the Kolari Vision Infrared Lens Filter (52mm, 590nm) the camera sensor in the D5500 needs to be modified. It will not work correctly with that.

Q: 8. which one of these is compatible with the sirui svs75 tripod?

A: Unfortunately, the EHRO Field Solutions Accessory Support were not tested with the Sirui Svs75 Tripod at this time.

Q: 9. What is the diopter strength of this close up filter?

A: It is a +1 diopter strength.

Q: 10. does the Nisha split field lens allow you to turn the position of the glass to achieve a more directed image?

A: Yes, it has a ring you can turn without unscrewing the filter.
