This filter is designed to make it so you can take pictures of solar activities! And it is DARK! It does the job well. The construction is a nice solid with a good weight. Screwes into my lens effortlessly. They did a great job putting it together. Get your hands on one now before they all disappear for the solar eclipse this year!

Update 1/26/2024 - an acquaintance asked about the lack of ISO-12312-2 certification in this ND filter, because he read a review that stated it was important. The ISO-12312-2 standard is meant ONLY for DIRECT VIEWING type glasses. It does NOT apply to to camera filter, as such you will not likely find that ISO cert on solar camera ND filters.

This filter does what it's advertised to do, reduce light by about 16.6 stops so you can safely take pictures of the Sun without damaging your sensor or your sight. I've included a quick test picture, sorry focus could be better. This is a good solar filter for a reasonable price.

I picked this up in preparation for a trip to (hopefully) catch the 2024 total solar eclipse. I intended to use it on a Nikon d300 with a Nikkor AF-S 300mm f/4.0 lens (and 1.4x teleconverter). I used this setup previously to photograph the 2017 eclipse, except with a homemade filter made from ISO 12312-2 compliant film.

When I saw this, I was excited by the prospect of having a true photographic filter to view and photograph the eclipse. But the more I looked into this, the more I don't think this is a good choice for me. The listing indicates that this filter is designed for solar photography, and that is not untrue. However, I will be shooting with an SLR, which provides a direct optical path to my eye. Unlike ISO 12312-2 compliant filters, there is no indication that this filter meets the safety standards necessary to ensure no damage to my vision. If my camera had a good way to live-view the image on the screen, that would not be as big a concern, but then I might need to worry about continuous exposure of the sensor to the same wavelengths that can damage my eyes (particularly UV).

So in the end, I'm not going to chance it. However, I may find some use for this filter in extreme long-exposure photography. I briefly attempted to play around with this handheld, but 16 stops is a LOT, and I was looking at exposures over 8 seconds (at ISO 3200!) just to get something that wasn't completely black.

The filter itself is nice enough, but I'm withholding a star because the listing should be absolutely clear as to whether this meets ISO 12312-2. Your eyesight is more precious than any photo you could possibly take. Be very careful using this filter to look at the son (even through a camera).

This little filter is pretty awesome. Packaging solid and impressive. I put this on my Canon 5d Mark 3 with my 70 -200L and it's pretty legit. I will say I am going to have to brush up on my settings being I typically shoot sports but this filter is a must have if you are going to shoot solar shots.

Pros:
Solid Packaging
Quality Materials
Well Made

Cons:
None as of yet but till update if there are any

This filter was a lot of fun to play with today. I used it with my A7 and did some really great solar shots. I love the grip on the filter. It is well made and the grip on the side is a nice, rugged feel. The lens itself I don’t really have many complaints. It feels amazing, looks high end, materials are top notch. The lens produced som amazing direct sunlight photos and the layering on the lens really made a huge difference. I have another lens with a few less coatings and you can tell a huge difference between the two. The only reason I deducted a star was because it was a little only to screw onto my lens. We all know lens cost the amount of your first born so I should never have to force screw anything lens onto it. It should glide easily. It took me a little longer to get it to glide onto my lens without making me cringe or gasp for air. Other than that little flaw, I love this lens and I do recommend it, especially if you’re into eclipse and moon shoots.

EPIC FILTER CASE WITH LINED RUBBER CIRCULAR SHAPE, SAVE A TONE OF $$ WITH THIS ND FILTER

K & F Concept has been around for a long time as a company making phenomenal gear.

They make everything from entry-level gear to professional COMMERICAL GRADE regarding various tripods, accessories, and other products.

Also, I've been in Photography for over 20 years.

I own three cameras from Canon (R3 x2 R5), totaling $15,000, and over $20,000 in RF glass with multiple accessories to shoot podcasts for professional events, motorsports, fighting conferences, and sporting events.

Moab, Utah, is one of my favorite places to shoot in the US.

It's always a challenge shooting into the sun at 5000+ feet; this is the perfect lens filter for that application.

I've purchased other filers that cost five times the amount of this one, which performs better.

One of my favorite aspects about the filter is how light it is!

I had to do a double take and read the description to ensure this was glass and not plastic.

Another thing I fell in love with is the cases.

I've had lens cases from the TOP 10 manufacturers in the world, and nothing compares to a case like this,

No matter what lens you use, it fits perfectly; it has a rubber indentation mark in the center to ensure the filter is locked in.

They have everything from 82mm down to a 43 mm filter that can fit into the case and is semi-translucent.

Based on this new system, I will order 10 cases and use a label maker to label all my lenses.

It's hard to explain my excitement when I opened the package and saw this case because it's one of the biggest challenges of being a photographer, especially good at shooting in the desert or extreme weather environments.

This is a perfect way to organize my lenses when shooting landscape photography.

As far as cleaning the actual filter, it's relatively easy.

I use professional Lint-free ultrasoft wipes, found here on K&F Concept

If you do not use these to clean lenses and filters, it's a game changer.

One of the biggest challenges is keeping lenses and filters clean and lint-free.

My three favorite parts are that it's 8K, waterproof, and has an anti-scratch coating.

I can't tell you how many times I've dropped a camera in the middle of nowhere, and the sphere of the current UV filter I have on there gets scratched up.

I'm looking forward to trying several high-end filters from K & F and becoming an ambassador for the company one day.

I can shoot more in Moab, Utah, and where I live. It is -10 out, and the last thing I want to do is freeze.

As a side note, the lowest I've ever shot is -10° -30 wind chill.

I'll be posting a 30-day supplemental review.

YOUTUBE STATEMENT ABOUT REVIEWS AND PHOTOS

I'm in the process of setting up my YouTube studio to create product reviews.

I plan to post a video review of this product on K&F Concept shortly.

Once the studio is ready, I will upload those videos on YouTube and share them here.

I use a Canon R3 camera with various RF lenses to capture professional product shots for my clients.

My experience includes commercial Photography at conferences, conventions, product shoots, podcasts, motorsports, PGA, MMA, and various events in Experiential Marketing across the USA and Canada.

The purpose of creating these video reviews is to help people understand the practical use of the product and how it compares to other products.

This will be beneficial for both K&F Concept and YouTube reviews.

Picked up this 100000ND ND Filter ahead of the upcoming solar eclipse. I tested it out a bit on a bright sunny day with the sun high in the sky. I was able to capture the sun with ease. It's going to take a few more times to get it dialed in as I've never shot with a 100000 ND filter before I ordered this. The build quality on this is top-notch. It comes in their new round filter case so I know it's safe and sound which is good because I know I'll be ready for that solar eclipse. K&F makes some of my favorite filters. I don't find much if any color shift. They are a high-quality filter at a good price. This is a niche filter so spending a good amount of money on a filter like this would be crazy. I think K&F filters allow you to be able to invest in a good filter without breaking the bank and still giving you an awesome look and high-quality images.

This filter does what it's advertised to do, reduce light by about 16.6 stops so you can safely take pictures of the Sun without damaging your sensor or your sight. I've included a quick test picture, sorry focus could be better. This is a good solar filter for a reasonable price.

Good for solar photography or long exposures during the day.
