After a year of daily use, I can honestly say the GH4 is performs exceptionally well across the entire range of features packed into a lightweight, weather-sealed body. The sensor and processors capture native 4K video, time-lapse photography and portraits particularly well. We are impressed with the ability to record powerful moments nature, news, travel, and family events right away, increasing with impact as we learn the camera. The overall size/convenience to power ratio is tipped way into the owner's favor. At one point I found myself in an intense urban setting overseas, and was very thankful to gather UHD video clips and quickly stash the camera and low-profile 20mm lens into my cargo pocket. Time lapse photography of the night skies have been breathtaking, and the setup was quite easy. The interface is quite usable from day one and progresses from there. I have adjusted the settings and function buttons to allow quick access to the features I need most. And I am excited about features like the Cinema settings for video. From there I can choose preset options to maximize the impact of footage going straight to finish or for editing later, or customizable for anything in between. Additionally, the sheer vastness of recording options, native and adaptable lenses means I can record events at essentially any resolution and detail fit for my editing software, medium of choice or client's budget. It's not without mention that the camera does have one caveat and that's the all-too-mentioned low-light performance. Indeed, in dimly-lit situations the camera will be outperformed by other cropped or full-frame sensors, and future GH iterations will continue to bridge the gap. However there are a dozen ways to compensate, and frankly I wasn't comfortable with sacrificing the GH4's existing features for other mirrorless or full-size systems that cannot compete with the GH4's size, value or feature set. Besides, for me as a professional videographer, no image or video goes to the client or website without at least some finishing. Therefore, I edit and fine-tune before posting or publication, and some compensation and de-noising for low-light performance just becomes part of your standard post-production work flow. Not only that, but my basic photo/ video journalism kit is capable of C4K footage, NFC for distribution, weighs less than 25lbs and fits in a 25L carry-on backpack. That means no fly and cry at baggage check. To that end the camera has traveled extensively and I noticed a little peeling in the weather seal just left of the battery grip. It was repaired along with some other small adjustments under warranty and returned in 9 days. In summary, I am delighted. The only real urgency for me is getting a 4K companion B-camera as soon as possible.
