This Nisha Split Field Filter includes an aluminum-alloy filter ring that can mount onto a lens with 58mm 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 58mm 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 58mm 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.

Related Questions and Answers

Q: 1. Do these screw on to the camera lense?

A: Yes it does, this is a 67mm filter.

Q: 2. Does this filter fit a Nikon 85 1.4 lens?

A: The Nikon AF-S 85mm f/1.4G lens takes 77mm filters, and this Hoya 67mm NXT Plus UV filter will not fit. Based on the history of Nikon's 85mm lenses, the only one with a 67mm-filter thread is the Nikon 85mm f/1.8G, not the f/1.4G.

Q: 3. Does anyone have photo examples of this lens?

A: This filter gives the appearance of 5 multiple exposures, similar to the image below: https://www.bhphotovideo.com/images/images500x500/Hoya_S77MV5F_77mm_Multivision_5F_Glass_94145.jpg

Q: 4. Is this a rotating filter for different darkness or is it just a straight one color?

A: A polarizing filter helps eliminate reflections, from shiny surfaces such as water, glass, etc. One can control unwanted reflections by rotating the filter to minimize or even eliminate reflections. This filter has no effect on colors.

Q: 5. Different Hoya Circular Polarizer Filters (NXT, HD2, etc) have different filter factors. Is the polarizing effect independent of that factor? Or to state it a different way, does the filter have two effects - polarizing & neutral density? So would a CP filter with a lower (smaller) filter factor be just as effective at the polarizing effect as one with a larger (bigger) filter factor?

A: That is actually a great question. My main experience is with B&W HTC polarizers and the Hoya HD3's. The Hoya HD3 has become my favorite polarizer because it is so bright and easy to use. I'm not sure if the degree of polarization is the same because of the extra brightness, but it works SO well that it does not seem to matter if there is a small loss in any way. Also, the HD3 goes very nicely from warm to cool as you rotate it which is very useful. When I go back to my B&W polarizer it works well only on bright days when there is a lot of light - so to put it bluntly, the HD3 will spoil you in every way and is worth the money.

Q: 6. Will this screw onto the front of a normal lens?

A: Yes! You can use this on any lens with a 55mm front thread diameter, or on larger/smaller lenses using a step-up/step-down ring. When using a step-up/down ring, your results may vary (strength of the effect, vignetting, etc.).

Q: 7. 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.

Q: 8. What is the depth or length of this hood?

A: This is 1” / 25mm from the front of the hood to the back of the threads. And It is 3 ¾” / 95mm wide at the front end.

Q: 9. Will this fit the Canon EF-S 18-55 f/4-f/5.6 IS STM lens?

A: Yes. Alternatively, you can also get the bayonet-style lens hood designed for this lens: https://www.bhphotovideo.com/c/product/945065-REG/canon_8268b001_ew_63c_lens_hood_for.html

Q: 10. Just to be sure, does the 49mm filter have a revolving feature as previous filters or is it a fixed immovable one?

A: Yes, all Circular Polarizing filters rotate.
