This 4 x 4" Tiffen Water White Glass IRND Filter is an ND filter with a 1,000x filter factor that provides a 10-stop exposure reduction. Its 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time or increasing your aperture, 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 and measures 4mm thick. 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.

Q: 4. How many stops is 1.5?

A: In ND measurements 1.5 is 5 stops of ND

Q: 5. What are the filter and stop factors for this filter?

A: The filter factor is 3 and the stop loss is 1 and 2/3 stop

Q: 6. Is this filter recommended for digital cameras as well, like the Lumix FZ200?

A: Yes, the Tiffen 52mm Digital HT (High Transmission) Circular Polarizing Multi-Coated Filter is compatible with the Panasonic Lumix DMC-FZ200 Digital Camera and would fit onto the 52mm filter threads on the front of the lens, and would be recommended for usage to reduce or eliminate glare and reflections from non-metallic items and (depending on your position and the position of the sun) can also darken/deepen the blue in the sky on blue sunny days. By removing glare, it would also slightly increase teh color saturation and contrast of your image.

Q: 7. Looking for a 77mm lens filters for my new nikon 70-200 f2.8. I'll be using in Iceland in winter when it might be gray overcast with lots of white snow? any suggestsion? on d750 camera
