The Canon 1DX Mark II results are now in the Sensor DB, and it’s our 50th camera to be added. WOW 50. It’s taken a few years, but the list is now becoming quite substantial, giving the community some good insight into the level and treatment of noise.
The results are good and there is a significant improvement at 5 mins compared with the 1Dx, which, I think is reflective of the new ISO range, allowing up to 409600 ISO. There has obviously been a sensor change from 17.9MP in the old model compared to 20.2MP in the new model, with the original 1DX slightly better with noise at 1 and 30 seconds. However the 1DXm2 gives very respectable results, and the difference could easily be attributed to the additional megapixels.
Of course the 1D series of cameras is not intended for astrophotography, and it would be hardly the camera to recommend for that task. But it’s nice to see it’s a solid performer none the less.
Again, a big thank you to Walch Optics for providing access to many of the models we test.
