This Nisha 58mm Split Field Filter Photography Lens Accessoryincludes 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.

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

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

Q: 2. Are these particular filters good for long exposure photography?

A: You could use these filters for long exposure photography, yes. These are general use filters, including a circular polarizer, and a neutral density filter, which would be the most practical of the three to use for long exposures.

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. 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: 5. 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: 6. Does it snap on my.lens?

A: This filter screws on to the filter threads of your lens.

Q: 7. How many filters fit into the filter case?

A: All three filters fit into the case, however I keep the UV and the polarizing filters screwed on the lens.

Q: 8. Do these come with a carrying pouch?

A: Yes, Nisha 82mm Close-Up Lens Set (+1, +2, +4, Macro) comes with a nylon carrying pouch for the lenses.

Q: 9. Will these filters fit the Cannon 58mm 18-55 and Cannon 58mm 75-300mm kit lenses that come with the EOS Rebel t5 camera kit?

A: The filters do. I didn't use the hood, as I have genuine Cannon hoods to mach every lens I have. You may have a problem using the hood on a long lens.

Q: 10. Are these filters glass? Are the frames plastic or aluminum?

A: Aluminum
