Zomei 55mm Star-Effect Cross Starburst Twinkle Lens + 4 Points Star Filter + 6 Points Star Filter + 8 Points Star Filter Set for Canon Nikon

Product Information

In Figures 1 and 2, you can see with your own eyes how much easier and more reliable it is to accurately judge the pattern of Focus On Stars filters than to estimate the size of the stars, i.e. when they are at their smallest. In the top row of images, in the middle three images the difference in size between the stars is barely visible. Maybe because you are young, have good eyesight and your camera has a great live view, you can still see it, but for most people it’s a big uncertainty with a lot of errors. Namib-Naukluft National Park, Namibia. Canon 5DIII, Canon 16-35mm f/2.8 II lens, ISO 100, f/13, 1⁄ 160 second. Don’t just shoot the sun

The “WIDE” version developed for wide-angle and ultra-wide-angle lenses. The “TELE” version developed for telephoto lenses. They are both adaptations and improvements of the Bahtinov mask for camera lenses, used in astronomical telescope.The thing that surprised me is that the filter gave better focus than focusing without the filter! I knew from experiments at home that it is faster to focus with the filter than without, but I thought the results would be the same. They were not. The "Kira Kira effect" is about way more than just creating stars and sparkle. In the right hands, this specialty filter can turn ordinary photographs into stylized dreamscapes. The invention made public by Russian amateur astronomer Pavel Bahtinov on an internet blog is a focusing mask based on the principle of diffraction that he developed for long-range telescopes. While researching the literature I found some promising devices on the internet, which are also recommended for wide-angle lenses by their manufacturers. They are all very similar: the well-known grid lines of the Bahtinov mask were laser-carved into a plastic sheet, relatively densely. They are available in square format or as a screw-in circular filter. I have tried a few of them. Although they work really well with longer focal lengths, I was disappointed using wide-angle and ultra-wide-angle lenses used for landscape astrophotography. The pattern was too small and too faint for any of them to be useful for my 2.8/14-24 lens. A large part of today's digital cameras comes with a convenient filter function (digital filter) installed. However, as for the final effect, there is no comparison whatsoever.

There is a difference between being in focus and being exactly in focus. If they are just a little out of focus, stars may look sharp, but the chromatic aberration will show up on the lenses, and the off-axis aberration will be greatly increased.

Typically, a small aperture such as f/11, f/16, or f/22 is necessary to produce an attractive burst; the smaller the aperture the better the effect, although you may want to avoid extreme apertures such as f/16 or f/22 because of diffraction (this same optical effect that produces the starburst effect also reduces overall image sharpness at small apertures). So, when choosing your aperture, you are trying to find the right balance between a crisp and bold starburst effect, and minimizing the sharpness-reducing effects of diffraction. Getting a good look at the night sky is optically demanding. When you gaze up to the stars, maybe you’ll see a constellation or a nebula or two. And that’s if it’s a clear night in the dark countryside. Most of the detail remains obscured. But with sufficiently precise sharpness adjustment, a significant improvement in quality can be achieved. Focus On Stars filters guarantee the maximum your optics can do – at a much lower price!
