The 72mm Formatt Hitech 72mm 2-Stop ND Filteris a solid neutral density filter providing a 2-stop reduction in exposure. This 0.6 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or longer shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

The design of this filter has been optimized for use with digital sensors and promote nearly flat attenuation of visible, UV, 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 provides a high level of neutrality across all three spectrums in order to eliminate color casts and ensure cleaner, truer blacks.

Applied to the outside of the Schott Superwite glass construction is a 15-layer Firecrest multicoating, which helps to minimize reflections and flare in order maintain truer colors and contrast. The multicoating is also scratch resistant and hydrophobic to benefit the overall durability of the filter. The filter is set within a 5.5mm-thick SuperSlim aluminum filter ring, which features front threads for stacking additional filters or attaching a lens cap.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

ND 0.6 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a 2-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.

Attenuates infrared light, as well as visible and UV wavelengths, to maintain color neutrality and suppress color casts due to increased exposure lengths.

The 15-layer Firecrest coating has been applied directly to the outside of the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multicoating is water and scratch resistant for greater overall durability.

Q: 1. What is outside diamater? I want to attach a screw in hood.

A: The outside diameter is 62mm.

Q: 2. Does this filter have a hard stop at each end of the range? My 62mm Bower variable ND does, just wondering if this version does as well. Thanks.

A: Yes, this filter has hard stops.

Q: 3. Hi i have a nikon 50mm 1.8 lens will this fit,cause on the box of the lens it said filter size 52mm ?

A: Yes. It will fit. The 52mm is referring to the diameter of the lens where the filter threads fit

Q: 4. Are their both inside and outside threads on this filter so that it can be included anywhere in a stack?

A: I note it is threaded on both sides.

Q: 5. Will this fit a 18-55mm nikon lens?

A: No, the Nikon 18-55mm is a 55mm lens filter.

Q: 6. Do the stop markings on the filter equal to 1/3 stop?

A: Yes

Q: 7. is this compatible with hasselblad hcd f4 28mm which does have a diameter of 95mm?

A: If the lens has threads on the front then it should fit.I use it on a Sigma 150-600

Q: 8. What size and type of lens cap works with this filter?

A: This filter will have a 67mm front thread that will work with most 67mm sized lens caps.

Q: 9. What size cap will fit this filter?

A: I contacted a technical Rep with Bower, and he tried it with both a standard type 52mm lens cap, and also the newer design many manufacturers are using with the center-pinch type and both fit without issue. I'm not sure what that comment in the customer reviews may have been experiencing but it will hold a standard 52mm lens cap.

Q: 10. is this filter compatible with Pentax 58mm lens?

A: I have used this filter with Canon lens. No problem. Also have mounted the filter in front of a HOYA uv filter. No problem. While I have not used it with any PENTAX lens, I would expect that there will be no problem since the mounting thread for 58mm is standard.
