Canon EOS 1DX: Twilight performance

Some months ago, a blog was written on bird-lens.com to review the Canon EOS 1DX and explain some aspects of dynamic range and noise in the CanonSumpfohreule, EOS 1DX performance.

As mentioned in the blog, some tests in photo laboratories show, that the dynamic range of the Canon EOS 1Dx benefits from having “only” 18 million pixels with a full frame sensor. For this you get a high dynamic range and a better signal / noise ratio. The Canon EOS 1Dx produces images with so little noise, that you can safely use high ISO values.

To give more examples, I show some images shot at dusk at the Laguna de Gallocanta. A Short-eared Owls (Asio flammeus) was hunting over Continue reading Canon EOS 1DX: Twilight performance

Canon EOS 1DX: some aspects of Dynamic range and Noise

100% crop of Golden Eagle at baitAfter blogging a review of the Canon EOS 1DX some people asked me wether I can subscribe what is written there and wether it is possible to show proof of what is said, that the dynamic range has improved significantly over the Mark IV.

Some tests in photo laboratories show, that Dynamic range of Canon EOS 1DX benefits from having “only” 18 million pixels with a full frame sensor. For this you get a high dynamic range and a better signal / noise ratio. The test showed a total dynamic range of nearly 11 stops at the low ISO settings in a RAW file. At 100 ISO RAW files, they found a usable dynamic range (while taking into account noise) of 7 stops and at a 6400 ISO jpg file still 6 stops.

The sensor of the Canon EOS 1D X use a new feature where there is no space between the pixels, and as much as possible of the incident light is actually converted into signal.  This is new in a professional Canon Continue reading Canon EOS 1DX: some aspects of Dynamic range and Noise
