Filter maker 84.5mm announces its first range of photographic products

By dpreview staff on May 1, 2012 at 22:43 GMT

Slovakian startup 84.5mm has announced it range of filters for photography and cinematography. The company's name is a reference to the size of its filters, which are designed to be compatible with Cokin's 'P' filter holders. Initially 84.5mm will offer a series of predominantly handmade ND Grads and colored filters, made from CR-39 (often called 'organic glass'). 

Press Release:

New Brand of square / gradual camera filters: 84.5mm

Dear friends of landscape, architectural and outdoor photography, we are pleased to announce you new brand of square / gradual photographic and cinematographic filters for both professional and amateur artists / photographers.

Company 84.5mm was established in year 2011 by a group of enthusiastic studio and outdoor photographers who joined forces with experienced chemists and production engineers. The idea of its origin was born in 2008, followed by three long years of development, research, laboratory experiments and fine-tuning best production technologies.

"In 2011 we could say that we have created an ideal manufacturing technology and a series of filters of exceptional quality that will please even the most demanding professionals and not only for its reasonable price." State the co-founders of the company.

Filters of brand 84.5mm are universally compatible and extended to fit square holder filter type P "84 to 85 mm" Filters are manufactured, similar as the world's most established brands of filter material CR-39, which has exceptional optical and mechanical properties - the same material is normally used for production of lightweight dioptric glasses or cockpits of combat aircraft and has exceptional scratch resistance and also optical properties very similar to the optical glass (Light transmittance, Refractive index, Abbe number, etc.). To ensure the highest quality, precision and control are all 84.5mm filters made by hand in majority of production stages! Each filter is tested visually, as well with using modern measuring devices in above standard equipped test center.

Founders of the brand also says "currently offered product portfolio of our optical filters is not final and we are currently developing dozens of new models that will soon appear on the market. Our long term goal is to come every year with attractive new models that will inspire hundreds of amateur and professional photographers around the world and the modern trends move steadily forward. Of course, while maintaining consistently high quality and favorable prices. "

You can learn more about 84.5mm brand and its products (including demonstration photos with and without filters) on the website:

Hello there,

i can only warn everybody buying these filters. The quality is way below Lee Filters and Singh-Ray. I would classify the quality as not acceptable at all and you should stay away from 84.5mm filter!

Here's why:
I bought 3 Filters of them in 100x150mm.
0.9 soft, 0.6 reverse and 0.9 reverse.

- Transition line of the 0.9 soft was not straight and lower on one side than on the other
- 0.9 didn't have a smooth transition from clear to ND. Looked like there was laying a sheet of paper when spraying the ink.
- The reverse grads are the worst i've ever seen. Both were darker at the edges than in the middle (on the short side)
- The 0.9 had a "cloud" of ink in the middle.
- In general i won't call these filters "Reverse ND Grad" but "Stripe ND"
- The 0.6 reverse didn't have a smooth transition from clear to ND. Looked as there was laying a sheet of paper when spraying the ink.
- In my opinion both reverse filters are much lower in neutral density then 0.6 and 0.9

As you can see in the images the filter look very much purple. I haven't taken any shots to compare them with Lee or Singh-Ray but from the color of the filters i can already imagine how the color cast they produce will look like...

Best regards

someone probably from this company has attacked me via private message for criticism of their grammar used in this announcement..well if this is the way they intend to do business, so be it and I wish them many customers happy with their services :D

Your assuming the culprit was this company, and laying blame out in public without any actual proof. Personally, I'd call that worse than disputing something in private messages. I think its rather childish to blame the company like that.

By stanic042 (May 10, 2012)

apparently you missed the word probably
what made me write that was fact that the message was written in their native language and apart from swearing they said "don`t you do this to my business"

Welcome to the photographic community. Maybe, these are creative, talented, driven folks who will come up with many interesting products. Don't we want entrepreneurs?

Maybe smart engineers but horrible business and marketing team.

One, what's with the name?

Two, if you're going for high-end product/market then target Lee filter owners and not some 84.5mm platform. Which BTW, with the name you've picked you're now stuck in it :P

By andrew jansen (May 2, 2012)

Mr Fartleberry, I agree.
Would we only use a filter when the camera's own dynamic range capabilities are stretched by the scene? Or because the filter offers effects that the digital darkroom cannot replicate as well?
I prefer to control my application of ND Grey filter once back in the digital darkroom thanks - at least there I can decide if a filter was called for, and in what position to place it, and how strongly to apply it.
Not to mention the optical compromise of glass in front of glass, scratches, or dust settling, and the time taken to load the filter on.
That is where Lightroom comes in.
Shoot the scene when the moment is best, and do the rest back at home.

Now I am keen to hear from anyone who can help me understand why I should still cart most or all of my old filters around with me.

Well you can emulate. But I'm pretty sure if the DR of the sensor is already stretched, a filter on place is better than any post production workflow.

A comment like this just demonstrates your inexperience as a photographer. I use Photoshop, but there are many, many effects achieved using filters that cannot be duplicated by Photoshop, such as the long exposures ND filters give you.
Also, which is a better use of your time: taking a few extra minutes to get a great shot using filters, or taking several hours of processing time trying to replicate the effect well in Photoshop.

Anything I can't do in Lightroom?

By ottovds (May 3, 2012)

I think someone in here should learn working with Photoshop. I hate the look of an ND grad for landscapes where suddenly a tree or something in the front plan also came darker. I rather make multiple exposures and use HDR techniques. Do mind HDR techniques can also be used in a subtle way...

By jimitav (May 2, 2012)

So now can I post "84.5mm" on the web without getting sued? :)

Good job, I'd like to give some filters in that range a test.

Sounds exciting....but sadly it also sounds very expensive...

It is pleasing to read about a producer from my country on DPR. However the site needs to be finished in order to look more professional.
P.S. I think the correct adjective is "slovak", not "slovakian".

As I understand it - Slovak is the name of the language or people, Slovakian is an adjective which means "of Slovakia". "Slovak is the Slovakian language" you might say.

By stanic042 (May 2, 2012)

adjective is slovak as well, slovakian is an incorrect, "dialect" form made up by people who don`t know the grammar because similar form is used e. g. "canadian", but you don`t call the country Canadia
slovak is the language of slovaks

By OneGuy (May 4, 2012)

Slovaks just got their independence. Yes, their press releases should be proofread. I hope they will shed some of their pride when it comes to business, also because the Slovak girls are rather pretty. (The Czech girls are prettier but you bring it up only when you want to start a war.)

Oh, its 46 mm for my lenses.

Nice, I visited their website and clicked to see some information on the ND-filters. Guess what, they are not made of CR-39 but of 'Lorum Ipsum'....

By adrian mctiernan (May 5, 2012)

Lorum Ipsum is Latin meaning 'Learn more', but I guess the material is not actually glass, but like the cokin filters, a kind of plastic, admittedly optical quality, but a plastic nonetheless. I have emailed them to find out, so we shall see

Yep, NBG if/when they expand their product range. Plus including punctuation character puts them at the mercy of the Google search algorithm. Strange marketing.

You don't have much imagination then. I can think of lots worse, "cabbage" for example, "tea party" perhaps. You must try harder.

So do B&H.

EVERYBODY called them B&H, but their website is "bandh" which looks more like Band H to me.

By CaseyComo (May 5, 2012)

How about if they called it "Tung Kee Noodle House?"

By changas2188 (May 2, 2012)

Looks good, but considering they are selling ND/Grad ND filters they still left some pretty dodgey halo's around some of their images.

By elFato (May 2, 2012)

I think No. Pictures in gallery are with postproduction, in HDR but pictures in product gallery are witouth any postproduction.

They write on webpage:
The following below are examples of some photography with the usage of the filter and without the usage of the filter.

Please note: The following photographs are not intended to showcase artistic qualities. This is not about artistic photos! The purpose of these photographs
are to show effect of filter in the strongest, raw and most intensive position / setting in order to show you its maximal possibilities/effect, while in real life you
will use filter in more gentle way, with less intensive effect / position of filter - up / down to regulate amount of effect/ and exposure setting.

No digital post-production (Photoshop, plug-Ins, etc.) were used! Photographed with a digital camera Canon EOS in the RAW format.

adrian mctiernan
By adrian mctiernan (May 5, 2012)

Personally, I find the photos of the filters confusing - they look as if they are suspended above a white table or background, and have uneven lighting units placed around them so that there is always a dark, offcentred patch to the right side, lower than the top, which is lighter to the left. I can't quite understand why they would photograph them like that - is the filter colored in the same way it appears, or what? - I should like to see what light changes actually are there in the filter - a smooth graduation is what I want, preferably ending a little below the halfway down area - what say you, folks?

Looks all great, but any word on pricing?

By SigmaChrome (May 2, 2012)

These filters are going to be Expensive. "... our filters are made by hand! (This means that more than 90% of operations in
the manufacturing of the filter are exclusively handmade quality (including the creation of transition effects) by our excellent team of trained and
experienced technicians. Therefore, our monthly output is partially limited and filters reasonably rare."

By photonius (May 2, 2012)

I think all these ND filters made of Cr-39 are "hand-made". I.e. Lee is, Hitech is, probably Singh-Ray as well. So prices shouldn't be higher than what is on the market.

Willem Steenis
By Willem Steenis (Apr 25, 2013)

Nice discussion :-)
Bought a couple of these 84,5 pro filters, so let's see what the quality looks like. 170 euros for three filters, the filter holder, sun cap and a nice box to store the equipment in. That is at least half the price of Lee and Stealth gear.... Will post some shots when stuf is in.

Willem Steenis
By Willem Steenis (11 months ago)

An update!
The filters are quite good! Not much distortion or unwanted color effects.
The company is unfortunately a different story... I ordered three filters (pro) and one of them was used, scratched and dirty! Buying is easy and fast, but the support is terrible. Not responding to mails etc. So, think twice before buying at this webshop! Maybe there are other distributors?
