In preparation for CP+ in Japan this month, Canon is set to announce new consumer products. We reported that the EOS 80D was coming in February, and along with it will come what may be a new kit lens, an EF-S 18-135 f/3.5-5.6 IS USM (the recent patent may have been for this lens) along Read more…
Adobe has had a rash of high profile bugs over the last few months, and it appears another major bug has been found in the latest version of Adobe Creative Cloud, an update Adobe has ceased from pushing out to users.
From Ars Technica:
The deletions happen whenever Mac users log in to the Adobe service after the update has been installed, according to officials from Backblaze, a data backup service whose users are being disproportionately inconvenienced by the bug. Upon sign in, a script activated by Creative Cloud deletes the contents in the alphabetically first folder in a Mac’s root directory. Backblaze users are being especially hit by the bug because the backup service relies on data stored in a hidden root folder called .bzvol. Because the folder is the alphabetically top-most hidden folder at the root of so many users’ drives, they are affected more than users of many other software packages. Read the full article
Backblaze users reported the issue in large numbers, but the bug can affect everyone.
Adobe has confirmed the bug
An Adobe spokeswoman issued a statement that read: “We are aware that some customers have experienced this issue and we are investigating in order to resolve the matter as quickly as possible. We are stopping the distribution of the update until the issue has been resolved.” The version that appears to be causing the deletions is 22.214.171.124, Pusin said.
If you’re running the affected version, it’s advised you don’t login to Creative Cloud until an update/fix is available.
Sigma is now teasing two lenses for a February 23, 2016 announcement.
The first is the larger “world’s first” lens. In the above image, it has been hypothesized that the lens has both a zoom and focus ring in the outline. Which is making a lot of the internet thing it’s a faster than f/2.8 short telephoto zoom.
We’re told this about the bigger of the two lenses.
The bigger one is indeed a zoom lens, but not a 24-70, not 70-200 and not a 85-135 or a 50-135/50-150
The second in the image above is a smaller prime lens. Sadly, it looks too small to be the 85mm f/1.4 Art series lens. It could be a lens for a mirrorless system(s).
*Note: Most of this information comes from the Sigma Hungary Facebook page, which I cannot find at the moment due to very slow internet access.
Canon is once again talking about their 250mp image sensor that they showcased at the Canon EXPO back in September. This time, they’ve presented a paper at the ISSCC 2016 Conference (All About Sensors).
Hirofumi Totsuka of Canon presented a 250 Mpixel APS-H size imager : 1.5 um pixel pitch (4 sharing) made in 0.13 um technology node. The device is consuming 1.97 W at full resolution 5fps. An interesting build-in feature of this sensor is the following : ALL pixel signals are converted by column SS-ADCs with a single ramp, but in front of the ADC, each column has its own PGA that can be switched to 4x or 1x gain, depending on the signal level. So when the pixels are sampled, a first check is done to look whether the signal is above or below a particular reference level, and then the right gain of the PGA is set to 1x or 4x. Simple method, but I think that the issues pop up in the reconstruction of the signal at the cross-over point between the two settings of the PGA.
This sensor does not mean that the APS-H sensor size is returning. We imagine that whenever the 250mp sensor comes to market, it will be in a full frame application.
