We have been waiting for a video like this. We like both of these cameras but they’re different and one will excel over the other depending on your purpose. The obvious advantage of the GX80/85 is the IBIS and the obvious advantage of the Sony is sensor size and AF.
Olympus’s $350 action camera is built to be rugged which does make it physically larger. It’s nice to see some more competition in this area as GoPro’s prices were getting out of control. This video camera has a small sized sensor which is standard for this kind of camera, and it features a waterproof and “crushproof” build.
This is an interesting comparison as these two cameras are similar in price even though they differ significantly in form factor. If you’re going to go for the Blackmagic then it makes more sense to get the 4.6K version unless budget prevents you.
The Panasonic GX85/80 is the goldilocks of Panasonic’s recent offerings. The G7 was and is great for the price, but it lacked IBIS. The GX8 is a good camera, but it’s large and its IBIS is more limited than we would like. The GX50/80 is small, has great IBIS, and is attractively priced. This is by far our favourite 4K capable camera Panasonic has released since the GH4. This also bodes well for the future GH5.
Do read EOSHD’s review of this wonderful camera. We are mostly in agreement. However, Andrew doesn’t touch on dynamic range and we don’t have a good side-to-side comparison with the Sony A6300 yet.
The Xiaomi Yi 4K Action Camera is an interesting and more affordable alternative to GoPro’s offerings. It features a Sony IMX377 image sensor and it can record at 4K at 30FPS (60mbps). Price is around $200.
We prefer the Sony A6300 for image quality (despite its rolling shutter and over-heating) to the Sony RX10 II but there are cases where the zoom range of the RX10 II will be more applicable to your shooting purposes.
Here are some highlights that matter to us:
- H.264 encoding 4K at 60Hz and decoding 4K at 120 Hz and 8K at 30Hz
- HEVC encoding 4K at 60Hz and decoding 4K at 120 Hz and 8K at 30Hz
- 10-bit HEVC encode and decode and 12-bit HEVC decode
This means that the above specs will trickle down to more affordable cards to use in a home theatre PC system. 10-bit 4K at 60Hz is the minimum standard we like as a future-proof specs that should last a person until 8K era.
