[Glass] I've been refining my ultra slow photography techniques for about a year now and figured it was time to graduate to 'the beast' - Firecrest's Nd1600. The results are amazing with the clarity I was hoping for, minimal barreling and silky smooth threading onto my lens.

Ultra slow photography is the most technically challenging in my photo skill set (I use a Pluto Trigger to do the math for me) and having a reliable 16 stop filter to rely on helps keep me focused on the art rather than the techno details.

[Glass] Rotating polas require turning to achieve the optimal effect, I choose the linear pola, no turning, just drop in your matte box and shoot.

[Glass] Highly recommended.


I purchased a 4-stop ND filter (1.2). It never comes off my Sigma 105mm f/1.4.


Practically all my headshots and portraits (250 clients) since the purchase were taken with this filter. I can keep the shutter speed in a reasonable range with strobes (1/30 -- 1/200) without relying on high-speed sync. I can also keep the strobes at a reasonable range (1/4 -- 1/128), which wouldn't be possible without a 4-stop loss of light transmission.


Other ND filters have funky colors - maybe I was lucky but this one has not created any noticeable color shift. Thank you Formatt!!

[Glass] For those who don’t know, British company Formatt was acquired by Tokina a few years ago. Tokina also started to make their own black supermist filter. I took a gamble and bought Formatt (and a 1/16) since they’ve been making filters longer. I don’t have any Tokina’s to compare but the quality is good. The 1/8 halation is nice and contrast reduction is just right for me.. I also like the Formatt’s pouch and magnetic seal.

[Glass] I was on a short road trip and used this alone, and with the Formatt Hitech 10 stop ND filter. The results were superb in both cases - no colour cast. An added benefit of the Formatt filter is it is very thin, so vignetting is less of an issue. I would encourage people to take a filter wrench, just in case...

[Glass] Another ND filter in my tool kit. Different brands can produce somewhat different effects. Some people like it, other's don't. I prefer to look at it as another option when making my picture. It is nice to have options. Optical quality is awesome, and that is what matters.

[Glass] Great filter thin with good threads

[Glass] I didn't see any reviews here, so I'd chime in:

I purchased this with the Sigma 105mm f/1.4, and surprised that it has no noticeably color cast (compared to some ND filters for my 85mm lens).

I'm quite satisfied. The glass is very thin and light, like 30-50% of the weight of a UV filter for the same diameter.


I use this to get wider apertures in the studio setting, given that my strobes can remain fairly strong, and the ambient lighting can either be cut at higher shutter speeds (1/200) or introduced at lower speeds (1/30-1/60). A joy to use.

[Glass] This does exactly what i wanted.. softens skin and blooms lights just the right amount. it's a very well balanced filter.
