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.

DayStar Filters ULF50-2 overview

  • 1Description

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.

DayStar Filters ULF50-2 reviews

50mm White-Light Universal Lens Solar Filter (2-Pack, 50-69mm OD) is rated 4.3 out of 5 by 190.
Rated 1 out of 5 by from Poorly Sized My Lens is 69mm on the nose and I was excited to have a solar filter with a snug fit. Sadly they measured the size from corner to corner, the correct size is flat side to flat side with measures at 60mm exactly, Far too small for the lens.

Rated 1 out of 5 by from Clouds mostly obscured the eclipse in New Mexico When you buy something inexpensive you can't expect too much. My expectations were realized. I had difficulty getting the lens to lay flat and it created lighter planes, creases and wrinkles that showed up poorly on the image. I had decided to use it on an old 50 mm Sony TRV 900 camcorder instead of one of my Nikon cameras. So I cut out the film part from the cardboard mount and laid it on top of the lens and secured it with a star filter ring. That worked just fine. I am glad I did not spend a lot of money on a filter because we had dense clouds for the majority of time the eclipse passed in Albuquerque. So it was all for the best in the final reckoning.

Rated 4 out of 5 by from Surprisingly Satisfied I made a last-minute purchase of this product to use for solar eclipse photography. It's not really clear from the marketing what you get ... this filter is made of the same coated film that the eclipse safety glasses use, and is housed in a flat cardboard frame that you fold and fasten (tabs / slots) to create 'as-pictured product. These come in pairs and are designed to be placed over the ends of binoculars. However, I was able with minimal adaptation to get this over the 70 - 300 mm lens. It worked great. I did not give 5 stars as this product is not as good as glass filter designed specifically to mount to a lens, but for a $25 outlay, I was very happy with the results.

Rated 4 out of 5 by from Solar Filter Prompt and accurate shipping from B&H. The filter is light weight cardboard and you must fold it together. Pretty easy to assembly, but a little flimsy for my liking. I put tape around the perimeter to secure it so it wouldn't come undone. I use a little bit of foam on the inside diameter to custom fit to my camera lens. The actual filter provided a very nice photo of the sun. There was no distortion I could see even when enlarging the picture. Overall I am pleased with the results, and for the price, you really can't argue.

Rated 5 out of 5 by from Eclipse ready As with other reviews, I suggest being careful in constructing these. I folded as per the instructions where the tab meets the filter and then folded the side tabs in, held the top tab over the contiguous tab and then opened the side tab to hold the sides in place. Best done on a flat surface for support. Fits two different cameras very well.

Rated 4 out of 5 by from Worked well with SONY camcorder, with some DIY Especially for the low cost of these filters, they worked very well for viewing and photographing the total eclipse at high telephoto settings of my SONY FDR-AX53 camcorder. I used gaffers tape to temporarily secure the filter. The assembled (bent and fastened with tabs as per instructions) filter in its cardboard mount was the same diameter as the large (55mm thread) Zeiss lens of the camcorder (no significant light leaks), and I taped only onto the knurled rim of the lens. I was able to rotate the lens with filter attached, enabling manual adjustment of exposure or focus.

Rated 4 out of 5 by from Good fix for using your binoculars during a solar event! This product worked well for viewing the recent solar eclipse using our binoculars. The only issue is that because it is essentially card stock paper that you put together, one of the two filters started to come apart in one area. If we had had tape with us, or a rubber band, either one would have worked well to hold the filter together and on to the binoculars -- both are very important as you don't want to have any sunlight coming through to your eyes. We will continue to use these in the future, just will have to do some diy fixing to get them to stay together.

Rated 5 out of 5 by from Formatt Hitech Universal Smartphone Camera Solar/Solar Eclip Great idea! Clip-on cell-phone filter holder is female-threaded for 37 mm filters, readily available. Excellent solar filter included. Two threaded clips with very strong springs provided with different reaches. The only negative aspect is unique to my set-up only, being a Nokia 808 cell-phone with a large bulge for the outstanding Zeiss camera lens. This part of the cell-phone is thicker than most cell-phones and it was tricky to shim the filter mount to remain flush with the lens. Pre-eclipse test photo attached. Recommended product. Pleased customer
