K&F Concept 58mm ND1000000 Ultra Dark ND Camera Lens Filter 20-Stops Fixed Neutral Density Filter with 28 Multi-Layer Coatings Waterproof & Scratch Resistant (Nano-X Series)

I have this on my 600 mm camera and a strait sunny day it filtered the sun down to a manageable level.

First of all: this filter is really, REALLY dark. It’s a little on the dark side even for direct shots of the Sun. I suppose it would be useful for close-ups of welding arcs, or maybe detailed photos of a nuclear detonation. Or EXTREMELY long exposures in bright daylight (sandy beach, high noon, f/11, ISO 100, 20 minutes?)This filter was well-packaged, although the ribbed side of the case did leave a small “print” on the filter’s front surface. I haven’t yet tried to remove it.The attached solar image was shot on a Canon 6D II, 100-400L at 400mm, 1/160, f/8, handheld and manually focused, stabilization on. I had to crank the ISO to 2500 to get this level of exposure. No other manipulation besides cropping and exporting as JPEG.Ideally, for direct solar photography, I’d prefer a filter three or four steps LIGHTER than this, shooting at lower ISO — but I’m still going to have plenty of fun with this one!There’s no specific information about IR or UV blocking on this filter, so I’m a bit reluctant to use it with the optical viewfinder. It’s PROBABLY safe, but I err on the side of caution when it comes to my eyes. I didn’t see any signs of trouble with my camera during the five or ten minutes that I was taking test shots.Recommended, but know what you’re getting into. And don’t be afraid of the dark!

I’ve accumulated several solar filters over time for photographing the sun, but none have impressed me quite like this ND filter. Specifically designed for my Nikon 200-500 f/5.6 lens with its 95mm filter threads, this filter has surpassed my expectations.Compared to my previous Thousand Oaks solar filters, which often imparted a slight blue tint to my photos, this ND filter offers a neutral view. It doesn’t alter the color or tint of the images and maintains similar exposure settings when capturing photos of the sun.I’m eagerly anticipating the upcoming Total Solar Eclipse in April, where I’ll put this ND filter to the test. I’m confident it will deliver exceptional results, and I look forward to updating this review with my experiences!

This is a well made and functional solar filter. I purchased the 82mm diameter version, ND1000000, 20 stop for use with a Fujifilm 150-600mm lens. The filter has a sturdy metal frame, with raised grooves to assist in loosening and tightening the filter. The filter itself is glass, but quite lightweight. It installed easily and securely to the lens, and allowed the lens cap to go on over the filter. It also comes with a nice carry case when not in use.The images of the sun with auto white balance come through in a neutral gray color, but boosting the white balance to a manual 8,000K gave a more pleasing yellow hue.My only question that I’m looking to have answered is the IR transmission of this filter. I want to make sure if I have this pointing at the sun for several hours during the upcoming eclipse (taking interval photos every five minutes or so), will enough infra red wavelengths come in to heat up and damage the camera sensor.Certainly a quality product and great for solar imaging.

This is a 20 stops ND filter!!This kind of filter is used for Long exposure photography.Long exposure photography is a technique that involves using a slow shutter speed to capture an image over an extended period of time, typically ranging from a few seconds to several minutes or even hours. This allows you to capture the movement of subjects in a unique and creative way, blurring them while keeping stationary elements sharp.I got my Rokinon 50mm Manual focus lens and gave it a spin. The images look sharp and the colors are loyal to the lens without the filter.K&F makes great and affordable filters and this one is no exception.
