ISO Sensitivity / Noise levels (contd.)

Raw noise compared EOS 5D Mark II vs Nikon D700 vs Sony A900 (ISO 1600 - 25600)

In this RAW comparison you get a better idea of how noisy these three cameras actually are without the veiling effect of in-camera noise reduction. As seen earlier, the Sony A900 is quite a noisy camera compared to the 5D Mark II and the D700, which are suprisingly similar (we'd expect the Nikon to be less noisy, but the difference is actually very small). All the way to ISO 25,600 the D700 and 5D Mark II are very close in terms of noise and fine detail retained, with the D700 slightly better at all settings. These results, especially at the top two ISO settings illustrate how much in-camera noise reduction is applied to JPEGs, and that both the 5D Mark II and D700 have very effective noise reduction algorithms.

sRAW1 noise (ISO 800 - 25600)

Here you can see the noise performance of the sRAW1 files. Compared to the full resolution RAW files, there is no noticeable noise advantage to shooting in sRAW1 mode. Considering that more fine detail is retained in the full size RAW file, in terms of high ISO noise performance there is really no reason to shoot sRAW1 over full resolution RAW.

For the sRAW1 file, the processing steps taken are as follows:

  • Load RAW file into Adobe Camera RAW (Auto mode disabled)
  • Set all noise reduction settings to 0 (all other settings default)
  • Open file to Photoshop
  • Save as a TIFF (for cropping) and as a JPEG quality 11 for download

I work in Nyc as a fashion photographer and I have to say the the 5d series are the most used cameras out side of medium format cameras .Ive been shooting with the mark 3 for over a year after shooting with the mark 2 for 2 years great both great cameras. You can see the shots I've taken with it for my work on my website www.brianschutzaphotography.com hope it helps!! also note I only shoot RAW format.

Was it really 2009? I'm still in the first flush of my love affair with this camera. And I'm still fathoming the depths of its capability. Okay, she's got a lot of paint missing these days, but the images are still magic. Whenever I use another camera, I sigh and wonder why I didn't use the 5D2.

As I know when the original 5D debuted three years ago, it wasn't clear why most enthusiasts would want such a camera. Though it captured excellent, high resolution images, it was slower and bigger and more expensive. Today the market has changed significantly, and it's clear that the market is ready for full-frame digital SLRs that can turn out high image quality. High quality is one thing, but being a camera that can deliver high quality over a wide range of lighting conditions and different ISO settings is what makes the Canon 5D Mark II such a compelling choice, and a clear Dave's Picks.
It's really very very good.
