Canon 6D and 5DMK3 Noise Comparability for Excessive ISO Lengthy Publicity


Astrophotography fanatic Don Marcotte needed to seek out out whether or not the Canon 6D or Canon 5D Mark III was extra appropriate for his area of images, so he pitted the 2 cameras towards one another in some noise exams at his native digicam retailer. did. He shot lengthy exposures with no lights on (cap on) to see how a lot noise could be seen within the body.

As you see the next pictures exhibiting the outcomes, remember that this take a look at was for a really particular objective and is probably not related to different forms of images. Marcotte tells us,

I used to be evaluating the 6D vs Mk III for a selected photographic software: night time scene with the sky within the background. Even with the tremendous large angle lens, the celebs will path behind in 26 seconds. However you want a number of photons to seize the sky. So I needed to discover a very low noise digicam that might give me what I wanted in 15 seconds and ISO 3200.

For this primary comparability, Marcotte shot a 15-second publicity with the 2 cameras in RAW mode with noise discount, transformed the photographs to 16-bit TIFF in Canon Digital Photograph Skilled, cropped 400x400px, after which gamma Prolonged to three.0. To see how a lot noise is current in Photoshop CS5:

This is the identical take a look at, besides the publicity time has been elevated to 30 seconds:

For the ultimate take a look at, Marcotte determined to pit the 2 new cameras towards his private Canon 5D Mark II, which has been modified for astrophotography. They used the identical process as the 2 exams above and a 15-second publicity time:

Right here comes the conclusion Marcotte, which he shared on Planet5D (he has revealed a protracted writeup of this take a look at):

6D ISO 3200 and 6400 . is the clear winner in 15 and 30 seconds for […] I count on nobody can detect the noise distinction between 6D and 5D3 for the overwhelming majority of daylight images. Solely in low gentle circumstances will the 6D produce higher outcomes.

It is fascinating that “entry-level” full-frame DSLRs outperform the higher-end ones, however what’s crazier is how significantly better the sensors in each cameras have gotten because the 5D Mark II.

Updates:DxOMark’s newest sensor exams of three cameras affirm Marcotte’s findings:
