Quality and Performance:
Going down the specs list for the Panasonic GH4, about all parts of the camera have gotten an overhaul or change contrasted with the GH3. The GH4's imaging sensor has gotten some cleaning, keeping in mind it keeps the same 16.05-megapixel determination, this new Digital Live MOS sensor highlights more extensive element range with an extended ISO 100 alternative (GH3 went as low as ISO 125) and takes into account a hour long knob screen.
Panasonic has likewise said the new sensor conveys double the readout speed contrasted with the GH3, which checked in at around 100 milliseconds. The new GH4 sensor is said to have a rapid readout of under 50 milliseconds. What does this all mean? The GH4 ought to be fundamentally better at taking care of moving screen in both stills (when utilizing the electronic shade) and video with Full HD 60 outlines for every second readout.
Combined with this new sensor is another quad-center imaging processor, the Venus Engine 9AHD. The new torque furnishes better affectability with a standard ISO scope of 200-25,600 (expandable down to ISO 100), and gloats new burst shooting execution at 12fps (in AF-S mode) for up to 40 RAW pictures or 100 JPEGs. The GH4 additionally gives a major change over the GH3 with consistent AF burst shooting at 7fps (up from only 4.2fps).
Panasonic likewise asserts that the new processor delivers better picture determination, dynamic reach and more precise hues, and also doing weighty calculating for 4K video encoding and giving a help to the GH4's AF speed.
The new GH4 uses Panasonic's quick balance identify AF consolidated with another innovation call "Profundity From Defocus" (DFD), which utilizes the lens data (when utilizing Lumix lenses) to compute the subject separation utilizing the out-of-center regions of the two pictures (one close and one far). This information is then consolidated with difference AF for conclusive tweaking, all inside 0.07 seconds for fast AF execution, assisting with sheer AF speed, as well as with expanded AF following execution and consistent AF burst shooting.
The GH4 likewise includes upgrades to persistent AF in both stills and video with better precision because of better wobbling (apparently meaning subtler forward and backward modification as it constantly looks after core interest). As indicated by Panasonic, since there is no requirement for on-chip stage identify pixels, on account of DFD, the full sensor is dedicated to picture quality (no missing pixels being utilized for AF).
The Panasonic GH4 highlights numerous other centering change seen on other late Panasonic cameras like the GX7 and GM1 including Pinpoint AF and higher AF execution in low-light conditions (- 4EV). The GH4 additionally presents some new elements for the GH line including a 49-region AF matrix (up from 23 on the GH3) with the capacity to physically choose custom AF zone groupings. There's additionally a uninhibitedly re-sizable 1-zone AF mode and face and eye location AF.
While the Panasonic GH4 without a doubt components a ton of upgrades for still photography, Panasonic themselves have said the picture quality is a slight change over the GX7, yet the principle center was definitely expanding the video recording elements, execution and picture quality.
The real issue with the GH4, as with the GH3 before it, is video recording. The GH3 cleared us out with its fantastic video recording components, and now the new GH4 gives not just much higher determination video, with both Cinema 4K (4,096 x 2,160) and 4K Ultra HD (3,840 x 2,160), additionally definitely expanded video bitrates for all intents and purposes no matter how you look at it contrasted with the GH3.
