DayStar Filters ULF90 overview

  • 1Description

Utilizing a spring-folded assembly design to hold it securely in place on a , the Daystar Filters 50mm White-Light Universal Lens Solar Filter allows you to safely view or photograph the sun and solar eclipses. Its filter is made of the 12312-2 ISO-certified SOLARITE film, which stops 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 lenses, telescopes, spotting scopes, or other optics and imaging devices, this version of the ULF can accommodate housings, sunshades, and dew shields with an outside diameter from 85-99mm (3.34-3.89"). The filter has a clear aperture of 90mm, so vignetting may occur when used on lenses and optics that approach the maximum recommended diameter in the size range.

DayStar Filters ULF90 reviews

90mm White-Light Universal Lens Solar Filter (Single, 85-99mm OD) is rated 4.6 out of 5 by 100.
Rated 4 out of 5 by from Solar Filter I bought this in anticipation of using it to image the upcoming solar eclipse. The item came packaged well, easy to assemble. The image quality was actually impressive considering the cost. It covered my Tamron 150-600 zoom well, I used a little velcro strap to keep it tight, but allow for easy removal when taking pictures during totality. My only concerns, it's not a robust design so don't expect to put it together and take it apart more than a few times, as such I only gave it 4 stars. I've uploaded 2 images taken with a Canon 6D and a Tamron 150-600mm. Both are heavily cropped but the image resolution is quite nice.

Rated 4 out of 5 by from The Filter Punches Above It's Weight I was pretty apprehensive about this filter when I ordered it, but it's turned out to be very solid for it's price. I'm using it on a Tamron 150-600 (original style, 95mm filter size) and it fits beautifully. Primary use will be for the solar eclipse in August 2017. The filter comes in a cardboard casing that is fold-able and slips over the front of the lens. It won't have a very long life. I've folded it and not messed with it a lot. The filter doesn't seem to distort sun photos. It seems to do a good job of reducing light through a long lens and gives good results. It won't be a long term, heavy use solution It has given me about 100 solar photos so far, and looks to be good for a whole lot more. I think it's a good solution for limited term use like the solar eclipse.

Rated 4 out of 5 by from Highly recommended I got the product 5 days before the 2017 Solar Eclipse. Put it together and actually put tape on the inside to hold the slits in place. Did test this over my eye glasses and it works. The day of the eclipse, August 21st shot 200 images. Tossing out the out of focus shots and bad exposes got a good number of keepers. Focusing with this filter or a welders #14 is difficult as the earth rotates but from talking with the other 7 photographers at the special photo shoot we all had the same issue no matter what we used for the filter. For the money it's a good deal and recommended. Have saved mine and protected the front filter to avoid scratches.

Rated 5 out of 5 by from This was great for the eclipse You look at this and think, cardboard and plastic - cheap. But in reality - it may be designed for not so many uses before you toss it, but you really get your money's worth! BUT - as it doesn't connect to the lens like other filters (just covers it is all), you will need to use gaffer's tape or painter's tape to hold it in place in case you want to reposition the camera and have it falling off. Also note: When taking pics like this - a tip I read on Canon's website - when taking pictures of the sun - once you get it in focus, use the gaffer's/painters' tape to secure the settings on your lens! That way any slight movements don't put it out of focus.

Rated 4 out of 5 by from Decent product, but TEST before the big day. Bought one of these to use for the Aug 21 2017 eclipse. I've done a bit of testing so far and it seems to work well, but realize it will give a fairly red-enhanced image. Look at histograms of blue sky with and without to see what I mean. Not an problem just something to be aware of beforehand. More importantly, test exposure differences against a patch of sky (not the sun) with and without the filter. It seems this is producing about a 19 stop effect, or about ND5.7 Note that many of the suggested exposure tables assume an ND5.0 filter effect. Take this into account beforehand.

Rated 4 out of 5 by from On The Sunny Side Of Life Took it out the other day to try it our for the upcoming solar eclipse. I wish I had more money for a real filter, glass... fitted.. professional... but this did an okay job. Better than nothing. And the glasses are an added bonus.
Date published: 2017-07-25
Rated 5 out of 5 by from Worked perfectly and economical I could not justify spending $100's of dollars on a dedicated glass filter for this one off eclipse event. This filter was the ideal economical solution. I bought this size and it fit perfectly over the lens hood for my Canon 35-350mm L lens. I used black electrical tape to wrap around the outside of the cardboard to prevent any light leaks and to hold it onto the lens hood. Worked great as I could attach and detach it quickly during eclipse totality. After that experience (sorry for expletive, but it's justified. F...ing unbelievable!!!), I've dismantled and stored this back in original packaging in case I chase another eclipse. Argentina sounds like a nice option.......

Rated 3 out of 5 by from size misleading Packaging stated that for 80-90mm aperture. Fits over outside diameters of 90-109 millimeters. B&H needs to update the product description online.
