Formatt Hitech FC100ND4.8 Overview

The Formatt Hitech 100 x 100mm Firecrest ND 4.8 Filter is a solid neutral density filter providing a 16 stop reduction in exposure. This 4.8 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 multi-coating, which helps to minimize reflections and flare in order maintain truer colors and contrast. The multi-coating is also scratch-resistant and hydrophobic to benefit the overall durability of the filter. It measures 3.9 x 3.9" / 100 x 100mm and is 0.08" / 2mm-thick, making it compatible with the Formatt Hitech 100mm Filter Holder.

Providing a 16 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 multi-coating is water- and scratch-resistance for greater overall durability.

Best ND Filter 10 stops or higher, Glass

This filter has either minimal or no color cast. I have used the B+W and Lee 3.0 ND filters and they both have color casts. The IR contamination is non-existent making post processing much easier. 16 stops is quite dense, a daylight exposure of 6 seconds F2 is needed for iso 160 if you follow the basic exposure rule of 1/iso @f16 and then account for 16 stops. This filter fits the basic Lee holder, making it quite convenient, and the glass makes it sharper than the plastic versions.

Waiting on the 8 or 10 stop version

As a prostop 10 owner, I was looking for something without the color cast. I decided to give this a try. It is a glass filter without the foam ring found on the prostop. Fits in the 100mm holder perfectly. I used some black gaffers tape around the outside of the frame to seal out the light. 16 stops blocks alot of light. Be ready for some real long exposures in lower light. No color cast at all.

I use this 100 x 100mm Firecrest IRND 4.8 Filter by Formatt Hitech in my 4X4 matte box to slow down water movement in seascapes. It works as designed with no noticeable color shift, even on very long exposures.

The Best

Works well for sun photos

I use this filter in a Chrosziel 4x4 matte box to take solar photos. It works well and seems to be neutral in color. It is VERY dark (15 stops) so you can't see anything through it that isn't as bright as the sun. In that regard, the 4x4 matte box works well in that you can slide the filter out for framing and than easily slide it back in for the photo without disturbing the camera.

No Color cast. Requires patience & care for good results.

Formatt Hitech made a good name for themselves because of their true neutral density filters (i.e. with no color cast compared to Cokin NDfilters). In fact, my first ever purchase from B&H Photo was for a set of filters, some 8 years ago! This is a square filter. It needs a square filter adapter. I used Cokin Z filter with it. It's dark. Really, really dark that you can not see through it yourself. Since you can see through it, you need to compose your photo before putting it on. Forget about autofocus. You need to focus the camera initially, then disengage AF, and install the filter carefully not to through your composition off or accidentally touch the focus ring. 16 stops means that if the appropriate shutter speed without it is 1/4000, then you will need to expose for 15 seconds with this. Patience ======= Given that 1/8000s is the most common top speed on cameras. An adapter of 16 stops would require that the exposure should be no faster than 8 seconds. Therefore, Tripod is REQUIRED no matter what. Typically we shoot landscapes at about f/5.6f/8, and the proper shutter at ISO 100 for this ranges from 1/30 to 1/250 on good light (Golden hour) So, here's the equivalentshutter speed you need when using a 16 Stop ND filter: Original Shutter speed====> Shutter speedwith filter 1/500s ==== down 16 stops ====> 2 minutes (120s) 1/250s ==== down 16 stops ====>4 minutes (240s) ... 1/60s ==== down 16 stops ====> 16 minute (960s) 1/30s ==== down 16 stops ====>32 minute (1920s) That's half an hour! You could be waiting 15 minutes between shots, and your tripod would have to be very stable when you shoot. If you miss your composition you will need to Compare this to a 10 stop filter: 1/500s ==== down 10 stops ====> 2 seconds 1/250s ==== down 10 stops ====>4 seconds ... 1/60s ==== down 10 stops ====>15 seconds 1/30s ==== down 10 stops ====>30 seconds The speeds for a 10 stop filter seem to work nicely for more common shooting conditions, like achieving motion of waterfalls. A 16 stop filter will help you achieve motion in the clouds! And once you get into exposures that are in the minutes, your lighting condition might change. Wind & dust could blow. Make sure you wipe the front of your filter with a microfiber cloth everytime. Special Care ========== The space between this square filter and the lens is not sealed (unlike screw-in filters), which causes light to leak through and give you weird results. This adapter comes with a plastic gasket that YOU need to glue to the glass (unlike Lee filters, which have it already glued). I didnt use the gasket. I simply wrap a piece of black clothes on it. You can also use a scarf or a beanie. Light can also leak through the optical viewfinder (the eyepiece), so you may want to seal that. In Canon DSLRs, the original equipment strap has a handy piece that can be used to block it. Suggestion ========= Use High ISO (highest maybe?) and largest aperture to shoot test shots at much slower speed, then once youre happy with your composition, go a head and dial ISO 100 and your desired aperture setting (and pray!) I suggest getting a phone app to calculate equivalent exposures to make your life easier. Also, if your camera does not have an intervalometer, get a remote shutter release cable that has that function. Wow.. that was a long review! Good luck!

No color cast Long Exposure Time Fits Lee Foundation Holder (almost) The only thing with this filter is that it is slightly narrower than my Lee Foundation holder so I have to use gaffers tape around the edges of the holder after the filter is in place. I used the foam that came with it but this still doesn't solve for it being narrower.

Why could the 2mm version of this filter not be used for video?
Asked by: Whtltng
16 stops of Neutral Density is too dark for a video camera to see through. The only way to use a filter this dark is on a stationary surface and with a DSLR that can shoot on Bulb mode.

How is the best way to clean this filter? Can you use panchro or is a microfiber cloth the best and only way to go?
Asked by: Anonymous
My understanding is that microfibre clothes can be cleaned by washing as long as the detergent has no fabric softener.

does this filter have a gasket to prevent light leak like on Lee's big stopper? Thank you for your time
Asked by: Anonymous
The Pro Stop filters have the rubber gasket. The Firecrest 4.8 does not have the gasket.
