Panasonic DMC-GH4EB-K Compact System Camera (Body Only)

Product Information

For [4K] or [C4K] video output, use an HDMI cable that has the HDMI logo on it, and that is described as"4K compatible". In the hand. On the physical side of things, if you're familiar with the GH3, then the GH4 has practically no learning curve in terms of handling and ergonomics. Despite the drastic weight- and space-saving benefits that come with the average mirrorless camera compared to the typical DSLR, the GH4 is certainly on the larger end of the spectrum with a more traditional DSLR design. Auto, Daylight, Cloudy, Shade, Incandescent, Flash, White Set 1/2/3/4, Color Temperature Setting (2,500-10,000K in 100K steps) For serious professional workflows, Panasonic also created alongside the GH4 an attachable interface unit, the AG-YAGH (or DMW-YAGH for the US), shown above, providing 4K HD-SDI output with timecode, XLR audio, and DC power. This gives the Panasonic GH4 the ability to integrate very well with professional cinema and high-end video production workflows with industry-standard connections and interfaces. Since the movie modes also employ an electronic shutter, Panasonic has tried hard to reduce the rolling shutter effect by speeding up the data readout of the GH4’s sensor. I believe it’s better than the GH3, but you can still trip it up under the right – or wrong – conditions. Either way though, I’m pleased Panasonic offer it as an option for stills, as it’s a rarity on other cameras. There’s certainly plenty of situations where the subject is fairly still in a quiet environment, and under those conditions a silent camera is very welcome.

In the Multiple Exposure mode the Panasonic Lumix GH4 combines multiple frames to create a single image.

LUMIX Digital Single Lens Mirrorless Camera DMC-GH4R

Still image: Max. 2x (Aspect ratio sets at 4:3. Not effective with L size recording. Magnification ratio depends on the recording pixels and aspect ratio.) Approx. 40 images (when there are RAW files with the particular speed)/Approx. 100 images (when there are no RAW files)/Approx. 120 images (when using electronic shutter)/(depending on memory card size, battery power, picture size, and compression)

The flash settings on the Panasonic Lumix DMC-GH4 are Auto, Auto/Red-eye Reduction (when iA, iA+), Forced On, Forced On/Red-eye Reduction, Slow Sync., and Slow Sync./Red-eye Reduction. These shots of a white coloured wall were taken at a distance of 1.5m. The GH4 does have some things the A7 does not, but then again, the a7 has some the GH4 does not (I like using digital zoom on the fly for instance and having FF and APSC modes). For stills, I much prefer the A7.....and I would prefer the a6000 too at the price. IF I was a video pro with control of the lighting, then the GH4 would be a great choice.To put the new technology to the test I compared the AF speed and confidence between the GH4 and EM1 fitted with a variety of different lenses. I started with the Lumix 14-140mm zoom which is a kit option for the GH4. Fitted with this lens, the GH4 focused almost instantly and almost always without any visible hunting. When fitted on the Olympus OMD EM1, the same lens focused a little slower and hunted a little more obviously, but remained fairly swift.

There’s no GPS built-into the Lumix GH4, but the Lumix Image app can be set up to record a GPS log with your phone that can later be synced with the camera. The process has been simplified with the latest version of the Image App. In the center, the GH4 has a standard hot shoe for mounting various accessories like the Panasonic DMW-MS2 Stereo/Shotgun mic, which thanks to the new processor and software in the GH4 is now able to zoom and adjust the balance between stereo and shotgun recording angles. The hot shoe is also compatible is flash units such as the new Panasonic Wireless Flash DMW-FL580L. Flanked on either side of the hot shoe sit left and right mics for stereo audio recording. x 2160 (24p), 3840 x 2160 (24p, 25p, 30p), 1920 x 1080 (24p, 25p, 30p, 50p, 60p), 1280 x 720 (24p, 25p, 30p), 640 x 480 (25p, 30p) The pop-up flash worked well indoors, with no red-eye and good overall exposure. The night photograph was excellent, with the maximum shutter speed of 60 seconds allowing you to capture plenty of light.

But what the GH4 does have in common with the EM1 along with every single other Micro Four Thirds camera on the market right now is the same 16 Megapixel resolution. In this respect it looks like Micro Four Thirds has stalled at this resolution. Sure the latest image processors are gradually refining the output, but I’m not seeing any significant jumps in image quality from the format. Use a card with SD Speed Class with "UHS-I Speed Class 3 (U3)" when recording motion pictures in [4K/100Mbps] [C4K/100Mbps] [FHD/100Mbps] or [FHD/200Mbps]. The Fn1 button, which as with the other four Function buttons on the rear of the camera and the two soft Function buttons on the touchscreen, can be configured to activate one of 38 settings, allowing the camera to truly be customised to suit your way of working (there are "only" 10 options available for the Fn4 button). The row of white balance, ISO and exposure compensation buttons make it extremely easy to access the camera's key exposure controls, while the dual control dials makes it easy to use the fully Manual shooting mode. A 4:3 viewfinder panel with 2359k dots equates to a resolution of 1024×768 pixels, which matches the best of the electronic viewfinders employed by the Olympus OMD EM1 and Fujifilm XT1. Interestingly though, the GH4’s magnification is lower, at 0.67x compared to 0.74x for the OMD EM1 and 0.77x for the Fujifilm XT1. This means the panel is magnified more on the Olympus and especially the Fujifilm, resulting in a larger apparent image size, albeit with no greater detail. It’s also important to consider how each camera formats the panels. In use the XT1’s wider 3:2 native image shape means its images don’t fill the vertical height of the panel, which reduces its size advantage a little. But as both the GH4 and EM1 have a 4:3 native image shape which matches their panels, the Olympus enjoys a noticeably larger image when both are used side-by-side. I should also note in very low light, the GH4’s viewfinder became noisier than the EM1, and with a lower refresh rate too when panning, but the EM1’s viewfinder image was noticeably darker, so there is a case of swings and roundabouts. The Panasonic Lumix DMC-GH4's Intelligent D-range feature adjusts the exposure setting to record more detail in the highlights and shadows, with three strengths available - low, standard and high.

But while I’m happy with the 16 Megapixel resolution of the GH4, I do wonder why Panasonic continues to not deploy embedded phase-detect AF points or consider dropping the optical low pass filter. The former could greatly increase the continuous AF confidence and the latter may deliver slightly greater sharpness at the pixel-level. Is there something about the Micro Four Thirds format which prevents this, or at least discourages its engineers from doing so? Maybe Panasonic doesn’t want to sacrifice precious real estate to AF sensors and is instead developing a dual function implementation like Canon has on the EOS 70D. Finger’s crossed. The Gh4 is not far off at base so it is not a big difference. But the combination of a better sensor when it comes to DR, tonal range, colour sensitivity PLUS 24 Mpixels indeed makes a notable difference. I don't know if there are good lenses for this cam, bit if so it is a better cam for that. Auto / Intelligent ISO / 100 (Extended) / 200 / 400 / 800 / 1600 / 3200 / 6400 / 12800 / 25600 (Changeable to 1/3 EV step) As it sits at the top of Panasonic's camera line-up, the GH4 is aimed at experienced photographers and, naturally, it has the usual program, aperture priority, shutter priority and manual exposure modes. However, there's also Panasonic's Intelligent Auto (iA) mode to help less experienced photographers and the Creative Control options that apply digital filter effects (Rough Monochrome and so on) to JPEG images.
