    Does the speed booster happen to come FREE when you buy the P4K?  If not then why the $1,000 cheaper comments from P4K owners?  This is not correct information to be spreading. 

    Sorry these prices are in Canadian $.

    P4K  $ 1749.00 + 13% tax =  $1976.00  https://www.vistek.ca/store/423994/blackmagic-design-pocket-cinema-camera-4k

    P6K  $ 3349.00 + 13% tax. = $3784.00  so the difference is $1808.00.  I can buy a Metabones speed booster 0.64X EF to M43 for $700.00

    The field of view will bit a bit wider with a P4K + Speedbooster. The crop with a P4K + Speedbooster = 1.28 (0.64x) or 1.42 (0.71x) vs. a standard super35 crop of 1.5-1.6.

    The P6K sensor is larger and is able to capture 6K raw images and some faster frame rates than the P4K. Most everything else is very similar / same. Also, I have seen comments to the effect that a 6K image downsampled to 4K makes up for the Bayer pattern and will produce a "true" 4K image. So, theoretically the P6K image may be a bit better than the P4K.

    Plus, you get bragging rights, since many people bash the P4K because it *only* has a M4/3 sensor. They won't be able to say that about the P6K (/sarc) :grin:

    The crop factor will be 1.26 ( 1.9 X 0.64)  vs 1.56.  So if you have FF EF lenses, P4K with SB could be better choice. $1000.00 cheaper too.  

    As for the image quality,  P6K downsample from 6K to 4K for  better image quality, but  don't you think the speed booster  when it concentrates the light/image  comes through the lens on the m43 sensor will increase the final image quality closer to 6K downsampling 4K ?

  3. This camera is going to lead the FF hybrid market with the Raw out put to Atomos ninja V this summer . 

    I use GH5 with Leica branded lens but would like to have more flexibility in colour grading. I was going to buy a  BMPCC 4k but after hearing the Nikon raw out to Prores RAW, I am seriously considering  to buy this camera.  The colour science seems better than Lumix S1.

    wouldn't it be amazing if panasonic worked together with metabones to make a 0.55x speedbooster so that they could hit the full frame audience 

    i think it will be technically difficult task given the clearance between the sensor and the mount. If you go more narrower, the Speedbooster will protrude and hit the sensor.  BMPCC 0.58X barely fits and you may also get soft corners and vignetting

    But does the 0.58X Speed Booster work with the 2x crop instead of 2.2x?

    Yes it does, I shoot pictures and occasional 1080P video.  Only issue i am having is with this setup is when a wide angle lens is used, the corners are slightly softer ( out of focus) if you focused in the middle of the frame. No issue with 35mm and up.  4K Crop on GH4 is actually 2.3 not 2.2. The plus side is 2 stops light gain, FF coverage and the FF Bokeh.

  5. Bravo Panasonic. i am already Using  a 0.58X BMPCC F mount Speed booster with my GH4. Now it is  With GH5,  i will have  0.58X 2 = 1.16 FF crop factor which is almost like a FF image and the 10Bit 4.2.2 is  a bonus!   Ready for preorder :)

  6. GH5 Would be an awesome camera to me if 

     The sensor is bigger than M43 like the one JVC use.

    10bit 4:2:2 internal processing and HDMI out with like the GH4.

    Better internal codec and colour science with more info for post work.  

    Manual  focus Zoom  in  option while recording.

    Better slow-motion options.

    Slightly bigger body than GH4 and Do not make it smaller than GH4.

    One  or two extra stops of light sensitivity over GH4

     

    Panasonic can also add dual base ISOs and IBIS  if they feel like giving us more :)

     

    The only thing that is going to make the GH5 popular like GH4 is the sensor size. not 6K.

  7. i do not think that Canon will not bring decent 4K video function in their DSLR lineup. They need to up sell their C XXX lineup to all the Canon faithful.

    That could be a reason they may not have C-Log in  1DX II plus that 500 Mbps MJpeg Codec is not gonna help either.

     

     

  8. Thanks for the review part 1 Andrew!  

    I wanted a FF 4K internal recording camera for very long time  to complement my GH4, i thought that Sony A7S II was my answer but these findings make me bit worried as i have put money down to preorder one here in Canada. i hope they fix these issues with a firmware update asap. i feel now that i should wait till the 5D Mark IV release. i want a FF 4K Video and OK Photo Camera. If i buy A7R II, Using Speed booster with S35 mode for video, then if i have to take a FF still, i have to remove the speedbooster, not practical at all, also when shooting with Speedbooster + Wide angel lens combination with minimum aperture, you get so much chromatic aberration.

  9. I am a very satisfied GH4 owner....... that does not mean i don't drool over A7s full frame glory.

     

    Would love to find out how they intercut in 4K mode. i guess i have to wait till the Shogun to hit the market.

     

    If the footage are indistinguishable,  An A7s is going to be in my tool box as B camera no matter what my wife says  ;)

     

    The Great thing is i can use the same lenses with speed boosters.
