The table below shows the star magnitudes that the AF can establish focus on at various focal lengths and maximum apertures, when a soft filter is attached to the lens*. I am using XXmm focal length and my maximum aperture is f/YY. Note: It is more difficult for the AF to achieve focus on reddish stars than other stars with the same level of brightness.īrightness (magnitude) of stars around Orion Stars can be classified by their magnitudes. The lower the magnitude number, the brighter the star. If the star is bright, the AF should be able to achieve focus on it even at maximum aperture f/2.8. It’s more precise than finding focus with the naked eye-the only prerequisite is a fast lens. The EOS R’s low-light focusing capabilities make it possible to use the AF to achieve focus on the stars.
However, it can be difficult to identify peak focus with this method, and I’m sure many find it challenging to control the lens, especially with the shorter focusing ring stroke on recent lenses. The usual way of taking a shot like the one above would be to magnify the Live View/EVF display to the maximum, and then focus using MF. With the EOS R, using MF is no longer your only option This technique is frequently employed in astrophotography. I used a soft filter to blur the starlight, which makes the stars look bigger and brighter. Focus was done with AF, with the focal point set on a magnitude 1 star in Orion. In this shot taken in the pitch-dark sky of the mountains, the winter constellations including Orion and the Pleiades sparkle brightly.

When using Live View: Shoot more comfortably with the Vari-angle LCD screen It displays the same information that you see in Live View, and you can preview exposure settings too.Ģ. If you prefer using a viewfinder: The EVF lets you "see" and focus in the darkįor those who like the direct feel of shooting through a viewfinder, the EVF provides a viable option for shooting in the dark. (Reported by: Shigemi Numazawa (Digital Camera Magazine))ģ reasons the EOS R is great for astrophotographyġ. In this article, we share some astrophotography tips and ideas to try with the EOS R. When you can barely see your surroundings, it can be hard to compose shots and focus on the stars, but the EOS R makes it surprisingly easy. The optimal exposure for capturing a starry sky is about four million times of that on a clear and sunny day.
