The 150 x 150mm LEE ProGlass IRND Filter 150x150mm 2-Stopfrom LEE ProGlass IRND Filter 150x150mm 2-Stopis an ND filter with a 4x filter factor that provides a 2-stop exposure reduction. Its 0.6 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you can 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 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 150 x 150mm ProGlass IRND 0.6 Filter Is constructed from scratch-resistant, optical glass for increased clarity as well as color fidelity.

Related Questions and Answers

Q: 1. Will this filter fit inside a standard mattebox 4x4 tray? We use the Genus Matte Box Lite and use Tiffin 4x4 filters without a problem, however the Tiffin 1,8 ND is twice the price of the Lee filter.The Lee filter has foam around the sides and is thinner than the Tiffin which is 4mm thick... so not sure it was meant for use in a matte box like the Genus. Thx for your help.

A: It will fit but be a somewhat tight fit because of the foam on the filter.

Q: 2. what is the light reduction in stops?

A: Because the Kase 150x150mm Wolverine Neutral Night Light Pollution Filter selectively blocks only certain wavelengths of light (yellow light from sodium-vapor lamps, mercury-vapor lamps, or low Color Rendering Index LEDs), there is no overall assignment of light-blocking capability for this filter.

Q: 3. There is a little soft thing around the edges of the filter which area is smaller than 77mm not mention to 82mm. Would it be possible to use LEE Filters Fujifilm GF 23mm f/4 R LM WR Lens Adapter Ring for 100mm System Filter Holder and no vignette for GF 23mm lens?

A: Yes you can use it with LEE Filters LEE100 Filter Holder B&H # LE100FH and LEE Filters 82mm Wide-Angle Lens Adapter Ring for 100mm System Filter Holder B&H # LEARWA82

Q: 4. Hi, there is a little soft thing around the edges of the filter to seal the light. But there is still big gap I can see, so how it suppose to seal the light then? appreciated any comment. Thanks.

A: There are two slots that the filter can go in. Be sure to put the Lee Stopper in the slot that is the closer to the camera with the soft part towards the camera as well. Those two things should keep light from filtering in. Also, make sure that you cover the eyepiece either with tape or the cover provided by the camera mfg.

Q: 5. one paragraph specifically says "This filter IS designed for direct solar viewing" then another paragraph says it is NOT ?

A: The Kolari Vision Pro IRND Filter (20-Stop, 77mm) does not allow direct solar viewing with your bare eyes/optical viewfinder. It allows for solar photography.

Q: 6. Does anyone know what it's: "IR Attenuation" ?

A: IR attenuation in the Ice 82mm Slim IRND1000 Filter (10-Stop) means that the filter reduces the amount of infrared light that can reach the camera sensor.

Q: 7. How thick is this filter?

A: This filter is approximately 2mm thick.

Q: 8. What is the thickness of this filter? 2mm?

A: The Kase 150 x 150 Wolverine neural night LiPo filter is 2mm thick.

Q: 9. Can this be used as a drop-in filter (with the threaded drop-in) with Canon 300mm f2.8L IS USM II & 600mm f4L IS USM II lenses?

A: Yes, the Hoya HD MKII IR ND8 Neutral Density Filter (52mm) can be used as a drop-in Canon EF 300mm f/2.8L IS II USM Lens and the Canon EF 600mm f/4L IS II USM Lens.

Q: 10. Does the Hoya MKII IRD have front threads in order to mount additional NDs ?

A: Yes, the Hoya HD MKII IR ND1000 Neutral Density Filter includes front filter threads so you can attach additional ND filters or a protective lens cap.
