About me:

Attended Zefram Cochrane high school in Bozeman, Montana. After I took a gap year to explore the rings of Saturn, it was time to buckle down and enter Starfleet Academy. I decided to pursue a double major in warp core theory and xenolinguistics. After a challenging four years, I received a commission as an ensign on the USS Bozeman II (NCC-1941-A). I was promoted to lieutenant 3 years later and was given the title of assistant chief engineer on the Bozeman II. Four years later, I was promoted to lieutenant commander and chief engineer of the Bozeman II, the position I currently hold.

Holistic Photog: I wouldn't assume that the 880Mbps Prores HQ on this camera beats the 400Mbps h264 All-I 10 bit on the GH5s. A lot of people seem to be making that assumption, but don't forget that h264 is a much more efficient codec. It's entirely possible that the 400Mbps h264 is packing in more detail, better motion rendering, and more latitude for grading than Prores HQ.

Some discussion here:

If that's the case, then you have to shoot RAW on this camera to beat the GH5s, and all the bitrate and file size issues that that entails. If that's what a shooter wants to do, then more power to you, but I sure wouldn't assume Prores is going to do it until actual, real world comparisons to the GH5s come out.

Then why include the Prores, if the whole point is RAW? Just a pointless inclusion? The fact is that there's a quite substantial difference in storage space requirements and even the media that you can record to if you use RAW. RAW is far more demanding.

The issue is that people seem to think that the Prores will also outperform the GH5s, and my point is, it may not, and it may even perform worse. There are probably a substantial subset of potential buyers who will use Prores, not RAW, and would be put off by the thought of having to use RAW.

That changes the whole equation IMO. You should know the relative performance of all the codecs on both cameras if you're trying to decide between them.

Also, I should mention that I've read reports that Panasonic might have made the GH5s RAW capable with a firmware upgrade, if they felt they needed it. It might be possible for that camera to get RAW if they felt a substantial threat from BM. I don't know for sure but it could be interesting.

Andre-ju: I'm very excited about this new 4K Blackmagic Pocket Cinema Camera. I have used the first version and it has some of the best HD output I have seen in a small form camera.

I love the styling on this one too. Most manufacturers go with a lookalike of another current camera or don't bother with lines at all. People get used to boring and predictable design, so kudos to Blackmagic for thinking about an alternative design to the boxy devices.

LingoDingo: So what do the Panasonic GH5/GH5s offer that the BMPCC 4K doesn't ?

- 2 to 3 hour battery life ( BM looks like it's 30-60 minutes )
- 3.68m-Dot OLED Viewfinder
- 5 axis IBIS ( the best IBIS for video work )
- Flip-out / rotatable LCD screen
- Weather proof body
- Dual XLR audio inputs ( with the $400 accessory )
- Exceptionally good GH5s noise-reduction up to ISO 25,600
- Panasonic reliability ( BM has had reliability issues in the past )

I think this new BMPCC 4K camera is an incredible bargain at $1300, but I don't see it replacing the GH5/GH5s for everything.

FLruckas, doesn't the GH5 have all of the features LindoDingo listed? He didn't cherry pick anything. They're all available in the GH5. The GH5s lacks IBIS. That's it.

Weird that they don't even list the weight. But the thing is a behemoth.

It seems capable of very good detail, even at max focal length.

Impressive for 360mm EFL in a pocket cam.

Theelderkeynes: I don't buy the Panaleica 15mm sharpness over the Sigma 16mm comment. As always evidence based analysis:

https://www.lenstip.com/412.4-Lens_review-Panasonic_Leica_DG_Summilux_15_mm_f_1.7_ASPH_Image_resolution.html

N'est pas?

Look at the DxO results for more accurate results. They have more sophisticated methodology for lens tests.

The 15mm is one of the sharpest corner to corner lenses in the system.

I don't like to look at lenstip for sharpness/resolution tests, but rather all the other testing they do. DxO for acutance/sharpness and lenstip for all the stuff DxO doesn't test.

tamras29: Forgive my ignorance, but what is the advantage of this beast overs a
Panasonic HC-VXF990 4K Camcorder at a third of the the price?
Interchangeable lenses I get, but what else am I missing?

7.5x crop factor vs 2x crop factor. The area of the GH5s sensor is more than 14x the camcorder sensor.

But, yeah, other than that, they're completely identical.

Why is it that you guys never do a proper comparison (in terms of hit rate) between DFD and OSPDAF mirrorless and DSLRs.

It appears that the hit rate on this camera is really as good as anything on the market, and I honestly don't think Olympus and Fuji would perform as well here. And it's my impression that Panasonic is dinged in the ratings for not going with OSPDAF even when your results don't bare that out.

The reasoning that this camera isn't as good for sports as PDAF doesn't follow from the success rate you achieved with this camera. I'd like to see Olympus, Fuji, and Sony in a head to head comparison here. I suspect the G9 will fare VERY well.
