The update of my A7c to firmware 2.01 failed. I follow every steps as on the sony website, open the system software updater, connect the camera without trying on. Turn on the camera with ensure the USB connected as mass storage mode, click next to the next step (Check the version). At first it shown “Verifying the connection of the camera and computer for update. Please wait… ” After a few mintues, but only find it shown that “Could not update. Complete the following procedures to update again…”
I followed the steps again, but failed again and again. I am using the USB cable came with the camera.
Good day Tim,
I’m a tad concerned of my A7C original battery depleting higher than normal just from extensively tweaking the camera settings, I even placed it in flight mode. I’l see how many shots I can pull from tomorrows shoot which shall be way to actually gauge performance.
My worries are that I might need extra batteries just to handle video work alone.
Are there any other updates included? I’d really appreciate having the ability to set the default function of the back wheel or dial to ISO, which would mitigate the ergonomics problem posed by lack of a front dial, when using primes that have an aperture dial on the lens.
Hey Tim. No other updates that I’m aware of, but you can already customize the rear wheel quite a lot. This section of the online help guide might help you to achieve what you want to do.
Sony’s A7C Firmware Update 2.00 instructions state: “For Mac users only macOS 10.14, 10.15 and 11 are supported”. What about the last macOS Monterey (version 12.0.1)? Will it work?
Hi Ricardo. I don’t have this Mac version installed yet to try myself I’m afraid. I’d just try it, you’ll soon find out if it doesn’t work.
I did and it worked.
Great! 🙂
