@endotoxic A often overlooked aspect of Micro 4/3 vs full frame or even more so apsc is that the m4/3 sensor is by design not as wide. So your kind of missing a major part of the equation that by choosing m4/3 for stills you accept this design decision. Many of us that came from medium format actually like this as it gives us a print friendly ratio we enjoyed with medium format. The difference when comparing just vertical height compared to apsc is significantly less. Oddly enough the loss of width is more daming in video where 16 x 9 is the accepted norm. Such a shame Panny abandoned the multiaspect sensor for this reason. Something I have missed is tethered shooting with CaptureOne that I hope will change with the GH5. Here is a 4K still from GX85 not even a proper still. I think we sometimes make false limits because there might be something a little better most clients could care less about equipment,

Just a question regarding SD cards for the GH5

I know that UHS II V60 orV90 cards are recommended for the GH5. Is that only for the 400 mbit neccessary or also for the "normal" video with 150 mbit. I have SD cards with 95 MB/s. Are the fast enough for the 150 mbit video? And if not, can one use a fast UHS II card for video in one card slot and the other 95 MB/s card in the other slot for photos? I know that this assigning is possible.

Alexa advantage is not only pixel size. It is also, and mainly, sensor response curves (filters they use define it).

I think there is something to dr and highlight roll off that always stands out for me more than anything else in the image. And I think a lot have the same feelings .. a used Alexa is 14-15 thousand in eBay these days which is really amazing ,that even after 6-7 years of its release its holding that much value ,and that is considered a steal for that old of technology .. the Panasonic image has improved ,from gh1 tell gh5 , but I would not say it's leaps and bounds ,it's the resolution that they have focused on ,and dr seemed to be least of the concern ,the main reason I moved from dslr to black magic cameras 3 years ago was the dr and codec ..let's not kid our self ,the Alexa is the king of image ,and usually you can spot it right away ,for some reason sony ,red ,and black magic has not gotten the magic recipe to compete with Alexa in terms of dr and highlight roll off for some reason or another ..hope that changes .

@endotoxic

Any modern interchangeable lens large(r) sensor digital camera is good enough most professional photographic applications, including the MFT format, since it gives you very large set of creative controls and generally very good image quality, except for certain very narrow and specialised applications . Mind you, the 135 film format, frequently addressed as the 'full frame' today, was created as news gathering, more portable, cheaper compromise to the 120 and large format photo standard, and the same issue always persists, what is 'enough' im the compromise.

The situation that we have, statement that MFT is not pro format in photography comes more from the artificial gaps and margins created by the industry, than by the real value and capabilities of the gear. So without precise definition of the specific situation where the MFT cameras underperform, and how exactly, it is mostly generalisation.

@Scot

yup i do only video. Though my company represents some pro fashion photographers. Neither of them use m4/3.

I use gh4 for small projects and do some pictures from the same work at the same time. That is the advantage of the system.

Personaly the format of the sensor is good enough for video even i have a thread about why i think is the best format cos is the same size of your retina.

But for Photography you encounter real best results from bigger sensors.

BUT I RECOGNISE IF m4/3 sensor tech could be applied on full frame size, we would have an exelent results. Better than current ff senzors I Think

There are lots of specs to consider but when you look at the image from a Sony 6500 or 6300 and compare it to any Panasonic there's a small but present IQ gap. I would have switched over at the latest upgrade round but I can't deal with the overheating, plus I have a boatload of lenses....

@1917

Some people here dont understand that DR can be higher on m4/3 sensors. Then as you said BMPCC "is black magic". Cos when i have worked on those cameras, the sensor size on it throw me more than GHs series. Even on 10 bit. and m4/3 is bigger sensor that super 16.

@1917, " I do not know any guy who bought gh4 for photo"

I bought two GH4's for both photo and video work. :)

@davedv all that numbers means nothing. You wrote that nex-5 has 12.2 stops))) Just look on footage and you will see big difference between gh4 and pocket/bmcc dr and color, and HUGE difference between gh4 and ursa 4,6k. A7s log is not usable because of 8bit (marketing).

BM sensors are 12 stops for Cinema cameras and 15 stops (barely) for Ursa. The Ursa body is twice the price of a GH5 with lens. It's time people realised that comparing a dedicated movie camera to a still camera with video options is just plain old f**ing ridiculous. I have seen the images from the x5s and colour graded them on a professional job. The specs look great but the images needed way more work than a GH4 or GH5. There is more to a camera than specs!

@davedv @caveport I dont understand one thing - are BM sensors gifts of god or aliens from another planet with their 13-15 steps? Im shure they soon will make compact camera from their cropped 4,6k sensor. Even x5s mft cam for copters can make 13 steps and 5k, and shoot in prores 4444xq + raw.

It seems like improvements in the dynamic range of Micro 4/3 sensors are happening at about the same pace as for other sensor sizes like APS-C.

For example, if you look at the sensor DR numbers from DxOMark:

Micro 4/3

• Panasonic GH2 (released 2010): 11.3 stops
• Olympus OM-D E-M1 Mark II (released 2016): 12.8 stops
• Improvement: 1.5 stops

APS-C

• Sony NEX-5 (released 2010): 12.2 stops
• Sony a6500 (released 2016): 13.7 stops
• Improvement: 1.5 stops

So basically in 6 years we have seen an increase of 1.5 stops of dynamic range.

It's true that the APS-C cameras are about 1 stop better than the Micro 4/3 cameras of the same generation, but that's roughly what you might expect given the larger sensor size.
