Key Features
  • Safe Solar Viewing and Photography
  • For Lenses, Telescopes, and Binoculars
  • 12312-2 ISO-Certified SOLARLITE Film
  • Fits Outside Diameters from 50-69mm
Utilizing an ingenious spring-folded assembly design to hold it securely in place, the 2-pack of Daystar Filters 50mm White-Light Universal Lens Solar Filters allows you to safely view or photograph the sun and solar eclipses. The ULF is offered here in a 2-pack for safe solar viewing with binoculars, or multiple optics and lenses without having to move the filter. They are made of the 12312-2 ISO-certified SOLARITE film, which blocks more than 99.999% of intense light, plus 100% of harmful IR and UV radiation — revealing sunspots and super granules on the solar surface. Made to fit on the front of camera lenses, telescopes, spotting scopes, binoculars or other optics and imaging devices, this version of the ULF can accommodate housings, sunshades, and dew shields with an outside diameter from 50-69mm (1.96-2.71"). The filter has a clear aperture of 50mm, so vignetting may occur when used on lenses and optics that approach the maximum recommended diameter in the size range.

SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

question

Seems pretty straight forward. I assume the filter would fit either my 18-55 (kit lens) or 55-200. Is the filter pretty easy to take on and off? (so I can take pictures without the filter when the moon is completely covering the sun)
Asked by: Mark H.
The important dimension is the outside diameter of your lens (not the focal length of your zoom). These fit over OUTSIDE DIAMETERS of 50-69 mm. I bought these for a pair of binoculars (50 mm wide - about 2 in.). I just tried it on one of my kit lenses (57 mm), and that looks like the perfect fit, based on the pre-folds in the cardboard housing. They won't work for my bigger lens though -- 77mm wide. Glad for your question, as it made me take mine out of the packaging and try them out.

question

Will this fit my nikkor 70-300?
Asked by: Mikaela M.
You need to measure the outside diameter of the entire front of the lens not the filter size the actual diameter of the body of the lens and then you can see which one of those will fit I hope you're not too late to get one because they're backordered good luck they work excellently

question

What is the neutral density or f/stop number of the DayStar filter?
Asked by: Trevor J.
I do not know - nothing in the documentation or on the product answers this question. I agree with David R's estimate (1 divided by 2, divided by 2, etc. 15 times (f-stops) gives you 0.0000152. Divide that by 1.5 f-stops yields 0.0000101 (1/1000 of 1%) for 16.5 f-stops. (=1/(2^16.5) = 0.0000108 in Excel).
