Sigma news and rumours: SPP 6.2.1 and firmware-updates for the DP1Q and DP2Q are now available!

During a talk two weeks ago, the owner and CEO of Sigma, Kazuto Yamaki, said that a new SPP version and firmware updates for the DPQs would be released. These updates, which increase the quality of the pictures and speed up the AF are now available for download. Since I do not dispose of any testing facilities, I could not test the AF; however, I did put the new algorithm in SP 6.2.1 through its paces. Even though the picture was taken with ISO200 and weak light, I compared it with the following photo. Due to these reasons, the noise is clearly visible in the 100% view, but even so it is one of my favourite photos.

I developed the X3F in SPP6.2 and 6.2.1 and exported it as a 16 bit tiff. Both times I used the exact same settings – everything apart from sharpness (-0.5) and noise reduction (Chroma and Luma to the far left or deactivated) was set to 0. In order to ensure comparability, I used the settings “Daylight” and “Standard” for white balance and colour mode, respectively. Afterwards I optimised the white balance, the brightness and the contrast (same settings for both photos) in Lightroom and created the 100% crops.

The following gif shows the differences in sharpness and noise reduction in more detail:

The picture developed with SPP 6.2.1 looks much sharper, but the noise is also more pronounced. As I have shown here, the colour mode “Standard” produces the highest micro-contrast, but also the strongest noise of all universally applicable colour modes. If one is prepared to forgo the higher micro-contrast in favour of better noise performance, the colour mode “Portrait” should be used. The following photo was taken with the DP2Q using an aperture of f/2.8 and ISO100, and was developed with SPP 6.2.1 (colour mode “Portrait”, sharpness -0.5).

As can be seen in the 100% crop below, the picture is sharp as a razor despite the noise being very low.

If you adjust the sharpness in LR a little more (amount 10, radius 1.5), it’s getting dangerous for your eyes. 😉

  1. […] the next couple of days I will look into the 6.3 version in the same way that I have done here with the SPP 6.2.1 version. […]

  2. […] huge difference when comparing 6.3 and 6.2.1. I was hoping for a noticeable increase in sharpness, like between 6.2.1 and 6.2. Unfortunately, this is not what happened. Even with a lot of good will, there is barely any […]
