A few days ago SIGMA published new firmware updates for lenses. The four new editions are models with Canon EF and Sigma SA mounts. The updates are said to have led to improvements concerning the auto-focus as well as to a reduction of the operating noise of the shutter lamellae. Sigma has published firmware updates for four of its lenses with Canon EF and three models with Sigma SA mounts.
There are updates for the following lenses, whereas the first three have been improved for SA and EF bayonet mounts and the 24-105mm lens can be downloaded for Canon EF bayonet mounts only.
17-70mm F2.8-4 DC MACRO OS HSM
18-200mm F3.5-6.3 DC MACRO OS HSM
18-300mm F3.5-6.3 DC MACRO OS HSM
24-105mm F4 DG OS HSM
SIGMA promises an improved AF performance in particular in connection with the lens adapter MC-11, which I’ve already tested for you recently . In connection with Sigma’s sd Quattro cameras the speed of the auto-focus, in particular, is said to have been enhanced.
Another improvement will make all the video enthusiasts among you very happy! With Canon EF mounts, AF exactitude in the LiveView and video modes are said to have been upgraded. Besides that, the operating noise of the shutter lamellae in the video mode was reduced, which has improved the sound while recording videos.
There’s also an update available for the Adapter MC-11. It enables the use of the upgraded lenses.
A few days ago, Sigma published firmware updates for the DP Quattro series. As can be seen in the change log below, this time around the focus was on the speed of the auto focus and on the compatibility with Eye-Fi memory cards. Since I was still on holiday when the news where published and only had the combo SD1/18-300 C with me, I could not install the new firmware version 1.06 on my DP2 Quattro to test whether the AF speed had really been improved.
Today I finally got around to doing this and I have to say, my first impression is indeed rather positive. The boost in speed feels much bigger than when the firmware was updated to firmware version 1.02. The DP2 Quattro focuses accurately and sufficiently fast even at f/2.8, ISO3200 and an exposure time of 1/10s or longer. And it does that without the assist light and with the smallest AF area selected. The DP3 Merrill takes more than twice as long under the same light conditions, and even then the camera often runs through the entire focus range before finally giving up. As soon as one goes outside, however, the advantage of the DP2Q lessens somewhat, as can be expected. The Quattro certainly is no Olympus OMD in terms of AF speed, but after all the firmware updates, it is noticeably faster and much more reliable at focusing than the DP3M.
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.
Sigma released three firmware updates – two for the DP1 Quattro and DP2 Quattro, and one for the 150-600mm f/5-6.3 Sports. Every FW remedies a single bug, respectively. You can read the short changelogs below.
Today Sigma has released the SPP Version 6.0.6 and a new Firmware Version 1.02 for the DP2 Quattro. The changelogs look promising. After the update, the camera is supposed to focus more reliably on dark, low-contrast motifs and it is supposed to get a “what you see is what you get” live view mode. SPP 6.0.6 is supposed to no longer have the „Beer Garden“ bug – at least that’s how I’m interpreting the text – resolution and saturation of the red channel are supposedly improved and a bug regarding multiple (external) hard drives has supposedly been fixed.
When I reported about the 24-105mm f/4 two weeks ago, I nourished hope that Sigma would present this and many more lenses at the PhotoPlus Expo. But things turned out differently. Sigma officially presented the lens even before the exhibition, at a RRP of €999 and available at the beginning of November. Instead of further lenses, I now have three smaller Sigma updates and news for you.
