Panasonic 4K GH4 possibly coming next Spring...

Going a bit further off-topic: although it helps but is not as critical to video, Olympus in particular has a secret weapon that is helping convince pro stills photographers to take a serious look at adopting the OM-D EM-1 in their work: their 5-axis in-body image stabilization (IBIS) system. People say that it is the best built-in camera/lens IS there is right now, and it works for any lens you have, regardless of vintage. The numbers that I have seen indicate at least a one-stop improvement on Canon's OIS. This can be very helpful for some types of shooting, including those that benefit from more usable low-light exposure.

This is the best explanation that I've read yet of why a professional photographer would choose to shoot Micro Four Thirds instead of Full Frame: http://lindsaydobsonphotography.com/...vs-full-frame/
 
Yep, I shoot a TON of science, food, tech, demonstration, and other close-in, macro-style stuff. It is definitely not a weak point of m43 systems.
 
I love the size of the Micro 4/3 sensor. Perfect balance of shallow depth of field and usability. Couple that with small, lightweight and inexpensive f/0.95 lenses, and I have a unique look to my photos and videos that won't kill my shoulders in the process.

Now I just want all that with 4K resolution. :)

But you can't expose at f/1.8, so you need 4 times as much light, which could be the difference between 2,000 watts of light and 8,000 watts of light.

In theory, with a sensor with 4 times the area, you can push the ISO up by 2 stops and you won't have any more noise. Of course, that's theory, and won't translate exactly to the real world, mainly because bigger sensors are slower to read and video mode usually resorts to things like line-skipping, which kills this big-sensor ISO advantage. But when read-out is the same, the rule holds (remember how the 5D2 could be pushed up to ISO 3200 but the 7D only to 1600? also, in stills, compare OMD-EM1 with A7 and you get about 1.5 stops of high-ISO advantage for FF)

Edit:
For the record, I don't want a FF sensor in my next camera. I want APS-C, with a mirrorless mount that allows me to put a speedbooster in front of it. That way I still have the advantages of a smaller sensor (faster readout), plus the FoV and DoF of FF (which I need because my lens set is all vintage glass that was designed for FF, and using it on a smaller sensor leaves me short of a wide angle option that keeps the look of the rest of the set) (the one advantage of FF that I wouldn't be getting, is sharpness, but I don't care about that one so much, you need lots of mpix to notice the difference between a real FF sensor and an APS-C sensor with speedbooster, tests here)

So -- as said before, the only magic you need to get the identical same field of view and the identical same DOF as a S35 sensor, is to open your iris by (a tiny tick more than) one f-stop.

In fact, if you run the math, you have to multiply by the crop factor. Same as with FoV.
Test here.

Thank You :)

Seems like you will have to wait for Panasonic to share their video engine with Fuji while they work on sensor development.

Until then, if you want the best video quality in a "SLR" form factor, the Panasonic GHx is still the way to go. And hopefully after Friday, even more so.....:thumbup:
 
I don't need a specific form factor, but I will definitely insist on a DSLR budget!!

Right now, my two biggest hopes are:
* that at some point Canon will have to start using sensors with as much DR as Sony/Nikon, and those cameras will probably still be able to record RAW through ML
* that Fairchild, the makers of the sCMOS chip inside the original BMC, are presenting a new generation of this sensor just next week (here) and it may be bigger than the first one; it would probably take a year for somebody to bring out a camera using it, but given how many sensors BM has bought from them, they may have given them a head start
Which means: I will probably keep my current camera until 2015 at least...

edit: maybe if this new Panasonic gets well over 12 stops of DR in RAW stills and either offers a log mode keeping all that range, or directly records RAW video...

4/3 Rumors says announced, not released. Considering they only had a mockup at CES, I would be really surprised if they released it this Friday. =)

I have a feeling Panny wants this out the door as soon as possible to take orders in before losing market share to various outer 4k cameras coming along.
I saw this on my FB. It was Defy Gimbal saying hinting that they had the GH4k on their G2 gimbal.

If it's just a GH3 with a 4K mode...meh. I'm with the camp that would rather see improved codecs and DR than 4K. 4K is a nice buzzword to sell more cameras, so I can see why they would go that way, it's just not that exciting to me.
 
This camera will have a whole new sensor than the Gh3. So while it will look like a Gh3, it can't be a Gh3 due to sensor. For those saying "I wish it was just a video camera with no stills mode", why not wait for a proper 4k camera that is just a video camera? I'm gonna bet that this camera ships before the end of the month because Panny is hurting and they want to beat the oncoming cameras that offer 4K.

??? This I can't really understand. If someone doesn't like the stills mode just don't go there. Simple. Don't use it. On the GH line it is clear that stills are secondary. To me a 4K camera with the GH functionallity and ergonomics is just fantastic. And any intelligent person understands that software as well as hardware developments in this area are still evolving. Codecs, sensors, etc. will continue to improve. Let's hope the GH4K brings many of these improvements with it now.

We will soon find out, won't we? Then it can be discussed with factual knowledge.

Yeah, that's true. Just thought maybe you might have a guess or 2. Feels to me like the GH3 pushed a lot of new things into a new weather sealed body, and it feels like it just came out, plus this is a speculation thread...waste of time, maybe so - but I always find it interesting to see what people might think.
