<p>The weekend is almost here, and you know what that means -- it's time for our weekly Firmware Friday roundup of all that's new in the world of camera updates. This week, we have several fairly straightforward updates to report on from Casio, Panasonic, and Sigma.</p><p>First up, Casio: The Japanese company is best-known for its watches, calculators, and keyboards in the USA, having discontinued its camera line here some years ago. In other markets, though, Casio still sells digital cameras, and four models in its unusual, swiveling EX-TR-series camera line have just received new firmware. In all four cases, there is but one change: improved reading of MicroSD cards. It isn't clear whether the improvement is in terms of read performance or read stability, but either way it's a worthwhile change for EX-TR series owners. Grab the updates at the links below:</p><p>Casio's EXILIM EX-TR350 digital camera.</p><p>Panasonic, meanwhile, is offering updated firmware for its Lumix DMC-GX7 compact system camera. There is only one change listed in the release notes, but it's an important one: improved stability whenever the camera is powered on. Get the firmware for Windows or Mac OS computers from Panasonic's Joint Update Service for Four Thirds website. (Scroll down, read the license, then click the 'accepted' button. You'll see the GX7 listed on the resulting page, along with a link to its firmware download page.)</p><p><a href="http://www.imaging-resource.com/news/2013/09/20/firmware-friday-casio-panasonic-camera-sigma-canon-mount-lens-updates">Keep reading...</a></p>
