This 4-stop, 77mm NiSi Nano Soft-Edge Graduated IRND Filter helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. The design of this filter incorporates a rotating mount to allow for precise positioning of the gradation along the horizon line. Neutral density filters do not affect the coloration of the image and the density provides up to a 4-stop reduction in light from entering the lens.

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. To provide neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces. The Nano coating associated with this filter also results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.

This NiSi 77mm Nano Soft-Edge Graduated IRND 1.2 Filter is constructed from H-K9L optical glass for increased clarity as well as color fidelity.

A: It is not. The bottom of this battery has a V-Mount connection, not the portion with a quick release plate to mount a camera.

Q: 2. Will the larger Evolution 9.25 tripod fit in this?

A: Sorry I cannot confirm since there are no dement ions on the tripod listed.

Q: 3. This charger has the option to charge at .25 A or .5 A does it matter which one I switch to charge my nucleus nano batteries?

A: We would tend to imagine that the .25a charge is slower than the .5a charge.

Q: 4. how do you make the soft bounce come back to shape?

A: The Profoto Soft Bounce for A1 Flash is designed to automatically fold up and to automatically pop up for use.

Q: 5. Why does the USB A port only supply power if the status button is depressed?

A: The USB-A port should constantly supply power to a connect device as long as the Fxlion Nano TWO Ultracompact V-Mount Battery (98Wh) has power. If you suppect you battery is having an issue please contact us at the following link. https://www.bhphotovideo.com/find/contactForm.jsp

Q: 7. Can this be used with a 24mm lens without vignetting? Extended or collapsed?

A: No for 24mm you would want the wide angel version. Sensei Wide-Angle Rubber Lens Hood (77mm) BH #SELHR2W77 • MFR #LHR2-W77

Q: 8. How many mirrorless cameras and monitors could be powered with one battery? Will one battery handle 2 GH5 cameras with x2 on camera 5" Feelworld monitors? (D-tap to monitor than from monitor to dummy GH5 battery)

A: This battery has these outputs: 2 x D-Tap - 2 x USB Type-A. Anything beyond these options would be more than the battery can handle.

Q: 9. How long does the battery last with the 6k Pro?

A: Around 2-3 hours.

Q: 10. The Westcott Fj80 has a magnetic round top too. Will the soft bounce connect to it?

A: To our knowledge, the Profoto Soft Bounce for A1 Flash has not been tested specifically with other flashes like the Westcott FJ80. The result may vary when using these two items together.
