The firm’s latest 4K camera is the Lumix DMC-G7. A successor to the two-year-old G6, the G7 is a brand-new camera that packs in the newest Panasonic tech.
The mirrorless Micro Four Thirds camera is compatible with 24 interchangeable lenses. Like many of Panasonic’s latest models, the big upgrade in the G7 from its predecessor is the ability to shoot 4K video (QFHD, 3,840 x 2,160 at 30p or 24p). And if consumers aren’t ready for 4K content yet, they can downsize to Full HD in the meantime. But one feature Panasonic is heavily touting is the ability to shoot 4K Photo. From a 4K/30p video, you can extract an 8-megapixel image (the camera crops into the 16-megapixel sensor). The 4K Photo feature, part of what Panasonic calls “New Hybrid Photography” (the ability to shoot regular photos, 4K photo, and 4K video), is designed to help you easily achieve this.
In the G7, Panasonic is introducing three new 4K Photo modes: 4K Burst Shooting, 4K Burst Start/Stop (S/S), and 4K Pre-burst. The idea behind these burst modes is, of course, to help the user always get that momentous shot. With 4K Burst Shooting, the camera shoots 4K photos (at 30 frames per second) continuously for as long as you hold down the shutter button. With 4K Burst S/S, the camera begins shooting at 30 fps when you press the shutter button once, and stops when you press it again; this mode is designed for longer wait times.
With 4K Pre-burst, the camera shoots 60 images from both before (yes, before — it begins recording when the camera registers a half-press of the shutter button) and after you press the button, helping you capture the moment in case you aren’t quick enough. And to give users quick access to these 4K drive modes, Panasonic added a 4K Photo option to the mode dial.
As for video recording, the G7 has an “endless” 4K recording time, letting you keep recording until you run out of memory or the battery dies; normally with 4K, there’s a 30-minute limit for each video clip. The built-in mic is now able to record stereo sound when the noise-reduction option is turned on. And, there’s a feature that lets you mark a favorite moment as you’re shooting, by pressing the Function 2 button; this helps you easily reference those scenes when in post-editing. And, a first for a Lumix camera, the G7 supports UHS II memory cards.
The G7 uses Panasonic’s newly developed 16-megapixel sensor and the latest Venus Engine image processor, borrowed from the GF7 and GH7 cameras, respectively. These components allow the camera to shoot in high-resolution, with less noise, Panasonic says, and improve image quality over its predecessor. The Venus Engine also helps to improve image quality when shooting with a small iris (aperture) opening.
“The Venus Engine image processor with quad-core CPU enables high speed signal processing. The advanced Multi-process NR (Noise Reduction) applies effective noise reduction and detail processing according to each component frequency. Plus, newly added Random Filter reduces chromatic noise in the image even more naturally. As a result, ISO 25,600 is achievable. The Venus Engine also improves accurate reproduction of each color not only in color phase but also in saturation and luminosity. In addition, the Venus Engine in LUMIX G7 excels in diffraction compensation making the resulting image crisp and clear even when shot at a small aperture.”
The G7 is designed to be an entry-level DSLR alternative, with performance and features to match or surpass DSLR. Panasonic’s contrast autofocus system has been greatly improved in speed (as fast as 0.07 seconds) and accuracy versus earlier systems. Incorporated Depth of Defocus technology (introduced in the GH4) helps to shorten focusing time by calculating “the distance to the subject by evaluating two images with different sharpness levels while consulting the data of optical characteristics of the current lens at that moment.” Burst mode is also improved, at 8 fps (single autofocus point) or 6 fps (continuous autofocus).
Another new feature is Starlight AF. By calculating the contrast value of each AF zone, the G7 can shoot the night sky with autofocus. Panasonic says the camera can shoot in low light, down to -4EV, which is equivalent to moonlight. Other autofocus features include Face/Eye Detection AF that focuses on the eye; Pinpoint AF for magnifying an area for precise focus; and a new AF Tracking algorithm that recognizes the color, size, and motion vector of a moving object.
Other notable specs include a max 1/16,000th of a second shutter speed; easier Wi-Fi pairing by removing the need to enter a password; wider panorama image capture (sacrificing image height for more width); OLED electronic viewfinder (EVF) with 2,360K-dot resolution, plus the ability to use the touch-panel on the LCD while using the EVF; 3-inch, flip-out, free-angle LCD with 1,040K-dot resolution; and DSLR-like ergonomics.
The G7 competes with mirrorless models like the Olympus OM-D E-M10 and Sony Alpha A6000. Panasonic describes the target user as someone in his/her 30s and 40s, who’s stepping up to a camera for shooting mainly memorable scenes with family and friends. For the U.S. market, Panasonic will sell the G7 in two kits, one with a 14-42mm kit lens for $800 (available in black or gunmetal), and one with a 14-140mm kit lens for $1,100 (black only). Because Panasonic is targeting new customers with the G7, no body-only option will be available at launch.
