This 58mm replacement water filter for lg refrigeratoris an ND filter with a 64x filter factor that provides a 6-stop exposure reduction. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible light and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times.

This filter is constructed from Water White glass for increased clarity as well as color fidelity. It is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Related Questions and Answers

Q: 1. Will this work with a Lee Foundation Holder or a Cokin Z-Pro holder?

A: Unfortunately no, this filter will not work. Those filter systems require square or rectangular filters.

Q: 2. Any vignetting when mounted on a Zeiss 15mm lenses?

A: Depending on the sensor size of the camera, you may experience vignette using this polarizer on a 15mm lens.

Q: 3. XS1500 compatible?

A: No. Please see below for the battery for the XS1500.

Q: 4. It is interesting that the SPECS do NOT list the voltage nor the Amp Hour rate of this battery. Perhaps by knowing that it is model RBC2 one should KNOW this info but I expect to find such basic details as volts and AMPS of a battery in the SPECS.So, what are those two numbers for this battery??

A: Please email us at pc@a href= http://bhphoto.com target= _blank bhphoto.com/a for assistance with your inquiry.

Q: 5. Will this work with the LEE Filters 105mm Accessory Front Thread Adapter Ring &H # LEFARPFK105?

A: yes, it will fit perfectly on the LEE Filters 105mm Accessory Front Thread Adapter Ring.

Q: 6. Is there any quality degradation on 150-600mm lens, at focal lenghts beyond 200mm?

A: The Sigma 95mm WR (Water Repellent) Circular Polarizer Filter would have the same effect on the lens at all focal lengths. While adding any optic in front of the optical formula of your lens will have some amount of effect to your lens' image quality, the Sigma 95mm WR (Water Repellent) Circular Polarizer Filter is a high-quality filter, and the benefit of its circular polarizing performance in reducing glare/flare from non-metallic items, increasing contrast/saturation, and deepening the blue hue in the sky (depending on your orientation to the sun) would mitigate any minor negative degradation you would obtain from using the filter on your lens.

Q: 7. Real-life experience comparison regarding the 'water repellant' coating of this filter vs., say, the B + W circular pola? Any difference in environments with rain/snow/humidity? Thanks.

A: Yes, the water repellent works quite well when it comes cleaning the filter without leaving streaks,etc...,as well as not fogging up.

Q: 8. Do these work with the Ikelite 8inch dome?

A: This is compatible with all Ikelite DSLR ports.

Q: 9. why am I having problems with scratches on the glasswhy am i getting scratches on the glass?

A: A filter like a lens is still glass and is sensitive to scratches like any other lens.Some filters are better than others. But a lens cap still needs to be used when using filter to protect it when you put it in a camera bag.

Q: 10. Is this the correct replacement battery for an APC backup system, CS 350?

A: We purchased it for the CS 500 and it worked perfectly. Not sure about other models.
