With the same sensor as the earlier GX8, the Panasonic GX9 isn't a huge update, despite the three-year gap between models. While minor updates may not mean current owners should rush out for the upgrade, for photographers in the market for a mirrorless camera under a grand, the GX9 still has a few features worth considering for the price tag.
The GX9 sports a 20.3 megapixel Micro Four Thirds sensor that can also record 4K video at 30 fps. True to Panasonic's reputation, the GX9 also includes a five-axis image stabilization system for steadier handheld images. Speed isn't the best in class with just 6 fps if you want to use continuous autofocus.
Panasonic has built in their 4K photo modes that turn video into stills for extra features, including post focus and focus stacking. The company also added a new mode to record action sequences and overlay the action into a single image. And while the 4K video is good, the GX9 doesn't have the endless recording (or rather, the ability to record until the battery dies) and 4K videos are cut short of 30 minutes and the frame rate is the slower 30 fps compared to the company's pricier models.
One of the biggest changes falls under design -- the GX9's electronic viewfinder tilts, along with the three-inch LCD screen.
The Panasonic GX9 shares more in common with the GX8 than it does new features. But, for photographers looking for a stabilized camera body with 4K for under $1,000, the GX9 fits the bill. For more video features, consider the GH5 or GH5s. Similarly-priced competitors include the Fujifilm X-T20 with a larger sensor but no in-body stabilization and the faster Sony a6300.
