How much more noise the 6D MkII exhibits is demonstrated here. Exposures were halved for each successive bump up in ISO speed, to ensure equally exposed images.Ĭomparing the sets, the 6D MkII shows a much greater tendency to exhibit a magenta cast in the shadows at very high ISOs, plus a lower contrast in the shadows at increasing ISOs, and slightly more luminance noise than the 6D. All were taken at the same aperture, f/2.8, with a 35mm lens. This set shows the same range of ISOs with the original 6D. In all cases, no noise reduction was applied in later processing, so the results do look worse than what processed images would.Ĭlick or tap on all images to expand each image to full screen for closer inspection. This set shows the 6D MkII at five ISOs, from ISO 1600 all the way up to the seldom-used ISO 25,600, all shot in Raw, not JPG. How well does the camera suppress the noise inherent in digital images when the signal is boosted to the high ISO settings we typically use? 6D Mark II noise at 5 ISO speeds The key characteristic of interest for night work is noise. The comparisons show close-ups of a scene shown in full in the smaller inset screen.
To test the Mark II against the original 6D I took test shots at the same time of a high-contrast moonlit scene in the backyard, using a range of ISO speeds typical of nightscape scenes. I have no interest in auto-focus performance (we shoot at night with focus set manually), nor how well a camera works for high-speed sports shooting.
My interest is in a camera’s performance for long-exposure astrophotography, with images taken at high ISO settings.
That makes it compatible with all external controllers for time-lapse shooting. One difference is that the port for a remote release is now on the front, but using the same solid 3-pin N3 connector as the 6D and other full-frame Canons.
The pixel pitch of the Mark II sensor is 5.7 microns vs. However, the new Mark II offers 6240 x 4160 pixels for 26 megapixels, a bump up in resolution over the 5472 x 3648 20-megapixel 6D. Shown on the left, above, the 6D Mark II is similar in size and weight to the original 6D. The original 6D, introduced in 2012 at that same list price, might still be available from many outlets, but for less, likely below $1500 US. The long-awaited Canon 6D Mark II camera is out, replacing the original 6D after that camera’s popular 5-year reign as a prime choice among astrophotographers for all kinds of sky images, including nightscapes and time-lapses.Īs all new cameras do, the 6D Mark II is currently fetching a full list price of $2000 U.S. No pretty pictures in this blog I’m afraid! This is a blog for gear geeks. In a technical blog I compare the new Canon 6D Mark II camera with its predecessor, the Canon 6D, with the focus on performance for nightscape astrophotography.
