The Panasonic Lumix DMC-GX85 is a mid-range interchangeable lens camera that is capable of recording video in 4K resolution and features a Four Thirds sensor with 16 megapixels. The GX85 is known as the GX80 in many countries and regions outside of North America. In Japan, however, it is known as the GX7 Mark II.
The GX85 is positioned just below the flagship GX8, and its primary audience is comprised of amateur photographers and videographers. It sticks with the tried-and-true 16MP sensor that is used on many other Micro Four Thirds cameras rather than using the new 20MP Four Thirds chip that we saw in the GX8. Instead, it uses the chip that we saw in the GX8. Additionally, the electronic viewfinder (EVF) does not tilt, it does not have weather sealing, and it does not have a microphone input as the GX8 does.

However, the GX85 has many of the same capabilities as its older sibling, including the 4K picture mode, Post Focus, Depth from Defocus AF, and Dual I.S. In addition to that, the shutter mechanism has been completely rethought. On the GX8, which had a motor and spring combination in its shutter mechanisms, we ran across a problem known as “shutter shock,” which caused blurring when the shutter was opened and closed. This issue is remedied with the brand-new electromagnetic shutter that can be found in the GX85.
Another first for Panasonic cameras, the GX85 lacks an anti-aliasing filter in its image sensor. This should lead to enhanced detail preservation at the pixel level, but it can potentially lead to moiré if it’s not done correctly. However, Panasonic asserts that the new Venus Engine image processor has been particularly calibrated to fight moiré and false color, and in our testing, we discovered that it performs a decent job of achieving these goals.
Dual I.S. is available on the GX85, just like it is on the GX8, and it combines sensor-based image stabilization with lens-based IS. The GX85, on the other hand, includes a 5-axis sensor IS that also corrects for rotation, in contrast to the GX8, which only has a 4-axis sensor IS. Another benefit that the GX85 has over its older sibling is that it is able to employ Dual IS when recording 4K footage, whereas the GX8 is unable to do so.
There is some debate as to whether the GX85 should be referred to as the younger sibling of the GX8 or the genuine successor to the GX7. The fact that the GX85 is known by a variety of names depending on where you are simply serves to add to the confusion. The chart that can be found above appears to provide evidence for both of these points of view: the GX85 makes use of the same field sequential EVF as the GX7 does (albeit it does not tilt), as well as what is likely the same sensor (sans AA filter). A pop-up flash is included, however it does not include weather sealing or ports for a microphone or headphones as the GX7 does.
However, aside from its sensor and electronic viewfinder (EVF), the GX85 shares a number of its essential components and specifications with the GX8, including its 49-point autofocus system, the ability to record 4K video, and a burst speed of 6 frames per second with autofocus. Therefore, regardless of how you look at it, the GX85 compares rather favorably not just to its fellow Panasonic products but also to the other brands in its class.
