    If BRAW is tied to Blackmagic FPGA that is a completely 360 degree turn away from ASIC and your power economy goes out the window.

    If ProRes RAW encoding also needs FPGA hardware, the heat management and battery life problems again scupper that.

    Speaking as an experienced FPGA design engineer, if you can implement it in an FPGA you could put into an ASIC (or into software, depending on how fast you need your processing to run).

    There is nothing magic or special about FPGAs other than their basic ability to be user programmed/re-programmed, which is their 'Unique Selling Point'. That makes them very attractive for low to medium volume products which need high-throughput data processing - instead of sinking a lot of up-front development capital into an ASIC. It also makes it a lot easier and cheaper to fix bugs and add features after you've launched the product.....

  2. The S1H firmware 2.0 update is now available from the Panasonic download page - https://av.jpn.support.panasonic.com/support/global/cs/dsc/download/index4.html

    (without the "RAW Video Data output over HDMI" function "due to some technical issues yet to be resolved")

    Quote

     

    Enhanced video functions / improved performance

    - Downconverted output over HDMI during [6K]/[5.9K]/[5.4K] video recording is available.

    - In Creative Video mode, it is possible to disable the operation of starting/stopping video recording by pressing a shutter button.

    - In Creative Video mode, it is possible to set [Rec Quality(My List)] from the control panel.

    - The value of noise reduction in [V-Log] in Photo Style has been expanded to [-1]. It suppress afterimages previously occurred in some situations.

    - It is possible to prevent the enlarged view window of MF Assist to be output over HDMI.

    - There were cases where color banding appeared in 4:2:0/10-bit video recording in some situations. This bug has been minimized.

    - There were cases where the REC RUN time code did not count up when the video was not recorded on an SD Memory Card but was recorded on an external device over HDMI. This bug has been fixed.

    Changed of operating specifications

    - To prevent improper operation, touch-control is disabled for [Delete All] operation in playback mode. Only cursor buttons can be used for [Delete All] operation.

    Improved AF performance

    - It is possible to set [AF+MF] in AFC mode.

    Improved compatibility with Panasonic interchangeable lenses

    - It is possible to assign functions to the lens’ Fn buttons when the Panasonic LUMIX S PRO 70-200mm F2.8 O.I.S. (S-E70200) is mounted.

    Improved compatibility with Sigma interchangeable lenses and mount converter

    - It is possible to assign function to the Fn buttons of Sigma L-Mount interchangeable lenses.

    - When attaching a lens using the Sigma MC-21 mount converter and [Image Stabilizer] > [Lens] is set to ON , Body I.S.(Image Stabilizer) suppresses roll movement.

    Other added functions

    - [Backlight Illumination Period] has been added to the menu of Status LCD. [ON1] prevents the LCD backlight to be turned off.

    - It is possible to select the card slot to save the JPEG images developed by in-camera RAW processing.

    - [0.5 SEC] has been added for an option of [Duration Time (photo)] in [Auto Review].

    - [Off (Disable Press and Hold)] can be assigned to the Fn button. It disables operation when the button is long-pressed.

    - Fn button can be used for checking aperture effect while the button is pressed.

    Other improvements

    - There were rare cases where the camera froze during [Segmented File Recording] or during recording at 400 Mbps under a particular set of conditions including the type of SD Card used. This phenomenon has been improved.

    - Aperture and shutter speed can be controlled using front/rear dials when the rear monitor is set to OFF.

    - There were cases where F value control failed depending on the maximum F value when non-Panasonic L-Mount lens is mounted. This bug has been fixed.

    I'd edit in 4K and export your finished edit in 1080p. Or just add the 4K footage to a 1080p timeline. No sense it degrading the quality by adding unnecessary transcoding the work flow. 

    I'd fully agree with that - it also means you can crop/zoom/re-frame/software stabilise with little quality loss (for 1080p output).

    Incidentally - if you need to convert 4k at 24p/25p/30p to double frame rate, the 'SVPcode' capabilty of SVP (SmoothVideo Project) is worth a look - I used it recently to up-convert 4Kp25 from the G80 to 4Kp50 to intercut with 4Kp50 from my G9 (final edit was 1080p50). It only costs $25 (for a 2 computer license) and as it uses FFmpeg for encoding, in theory you can output the converted footage in any of the encoding formats FFmpeg supports e.g. ProRes. If you intend to up-convert the footage, i think it's better to shoot it with a shutter speed matching the up-converted frame rate e.g. use 1/100s for 25p - that will look better and also provides sharper frames for the software to work with when it does the motion interpolation.

    I found the g80 for around 300€ used

    At that price, if it's in decent condition, just buy it... Then add a few cheap 3rd part batteries, V30 rated SDXC cards (for 4K) and some cheap but good lenses and go out and have fun!

    (I own a G80, G9 and GX80 - the G9 will beat the other two hands-down for video quality but the G80 is smaller and lighter, and the GX80 is the one I usually pick up if I want to take a camera with me 'just in case'. Which one is my favorite - hard to say, it depends on the situation...)

  5. Based on a quick look at dealer prices for *used* G6, G7 and GX80 in the UK, the G6 is maybe £120-160 (but there are not than many listed), the G7 around £250 and the GX80 around £200. 

    On that basis, unless you can find a really good deal on a G6 or you need a mic input, I'd go for a used GX80.

  6. I'd agree with most of the above suggestions (having owned most of the cameras mentioned) - personally I'd go with the LX100 or GX80/85 and take a small/cheap audio recorder with a mic input to workaround the lack of mic input on those. The GX80/85 has the advantage of USB charging so that's one less thing to take with you, and the video autofocus is much better than the LX100, if that matters.

    If you are considering the GH1 then add the G6 to list - as Andrew commented in his review years ago, it's a 'GH2 redux' with good 1080p (up to 50/60p) plus a mic input,  lightweight, and it's very cheap secondhand (as are 3rd party batteries and USB chargers for them). No IBIS though so you need stabilised lenses or a tripod.

    As a general versatile 'travel camera' I've taken a GX80 plus 14-140mm Panasonic zoom lens a few times - overall smaller than some 'superzoom' cameras, dual-IS, nice to use, EVF+tilt LCD, good 1080p and 4k video with excellent stabilisation and USB charging - what's not to like?

  7. Apologies if this has already been mentioned, but I was just looking at the Lumix firmware update page and noticed an update for the S1H was added on 10th December (version 1.1) - https://av.jpn.support.panasonic.com/support/global/cs/dsc/download/index4.html#

    The change log:

    Quote

    Expanded compatibility with Profoto wireless transmitters

    - Profoto wireless transmitters "Air Remote TTL-O/P" and "Profoto Connect-O/P" can be used.

    * All functions may not be available depending on the situation.

    Performance improvement

    - There were cases where block noise increases depending on the subject in HFR (High Frame Rate) mode. This bug has been fixed.

     

  8. I've been using 'SanDisk Extreme PLUS 128 GB microSDXC Memory Card + SD Adapter' in a G80 at 100 Mbps &  a G9 at 150 Mbps (4k50p) recently on a long trip. Note that they are only 'V30' video rated - this means they should sustain a minimum of 30 Mbytes/sec write speed (=240 Mbps), so are not suitable for 400 Mbps.

    See here for SD card video speed ratings - https://www.sdcard.org/consumers/choices/speed_class/index.htmlhttps://www.sdcard.org/consumers/choices/speed_class/index.html

    I'm saying that $1k is nothing compared to what people are spending on upgrading cameras that are already fine (and those cameras were to replace other cameras that were probably also fine)!

    But that upgrading is what pays for the development costs of the new cameras - if people didn't buy them there wouldn't be A7IV/EOS-R/S1/Z6 etc. to drool over... ? (nor would there be loads of cheap second-hand camera bodies available for those on a tight budget).

  10. With Sony, Canon, Nikon and Panasonic all now seriously in the full-frame mirrorless market, there's the inevitable price war going on, so the 'street price' for a new 24 megapixel camera body seems to be settling at the 1500-2000 $/£/€ price level. Panasonic can't be too far out of line with that pricing if they want to sell the S1 in reasonable volumes.

    Re. them selling off the chip business - I'm not that surprised, they are a small player in it, fabrication plants are very capital intensive things and the chip business can be very cyclical. As Mokara says, it doesn't stop them designing their own chips and having them manufactured by a 'foundry' - that's how most chip companies work anyway (even some major players like Broadcom, Qualcomm, AMD etc. are 'fabless'). I think Panasonic are (sensibly) far more interested in fast growing markets like rechargeable battery production for vehicles than chip making.

    Wouldn't the lowlight in the G80 at 1080 be better than from a G5/G6?

    Yes, it is (and the G9 is even better). Due I suspect to a mixture of more sophisticated noise filtering and some sensor performance improvement.

  12. Good deal on a Panasonic G9 body plus accessories for £899 at WEX in the UK - https://www.wexphotovideo.com/panasonic-lumix-g9-digital-camera-with-25mm-lens-dmw-bgg9e-battery-grip-and-2x-dmw-blf19-1723562/

    1080 isn't good in the G85?? I thought it was decent (at least compared to how poor the a6300 did its 1080 vs 4K....)

    IMHO, it's quite decent, but it does suffer from some aliasing e.g. on brickwork/roof tiles etc. perhaps contributed to by it being a bit over-sharpened. On the plus side, I've never noticed any moire.

    Put it another way, I've owned the G5 & G6 and I don't think the G80 1080p looks much better overall than those two, just a bit different (it looks sharper and punchier but I think you pay for that with some occasional moderate aliasing problems).

    Would have put more pressure on the G85 prices to come down.....  (I want one!)

    The street price of the body-only version of the G80 has almost halved in the UK over the last three years (so it's not much more than the G7 now), so I suspect it's almost bottomed-out.

    I'd watch for cashback offers over December/January, especially if Panasonic do a 'double-cashback' promotion for a short period as they sometimes do (I got that on my G9 back in April during the last 'Easter' period promotion).

    The poor G95. What a blunder. 

    The G90/G95 does have unlimited video record time and V-Log L as standard, and it's a bit smaller and lighter than the G9.

    But I agree - it's too expensive in comparison to the G9 and GH5 (and almost twice the price of the very capable G80/G85).

    I can't see many people buying one when they could get a G9 for the same price or a GH5 for only £150 more...(based on current UK street prices).

  16. Now it's out, the updated user guide for firmware V2.0 lists a few more updates than were mentioned in the news release (European English version is here -  https://eww.pavc.panasonic.co.jp/dscoi/DC-G9/EG_EC_EF_EB/DC-G9_DVQP1406ZC_full_eng.pdf  - see the 'Firmware Update' section at the end, page F-10 onwards - there are 20 new user guide pages to cover the changes!)

    In particular, recording to MOV files (with LPCM audio) has been added, including FHD 10-bit 4:2:2 25/30/50/60p at 100 Mbps and 4k 10-bit 4:2:2 24/25/30p at 150 Mbps.

    The 10bit 4:2:2 4k recording can be in HEVC (72 Mbps MP4 with AAC audio and HLG video) or H264 (150 Mbps MOV with LPCM audio).

    Edit: either that, or the "motion blur" on the Canon is blurring from compression as well. More motion will strain interframe compression more, so lots of movement will make for a less detailed frame overall. The Canon might be suffering there.

    It might also be using temporal filtering (before compression) which can smear motion in some circumstances - remember we are talking about a consumer-grade T6i DSLR here.

    DesslerLord - have you tried applying softening/motion blur filters during editing to the 4k footage from the modern cameras?

    More likely to be to do with tax laws I would have thought.

    Not the for the 10 minute 4k 50/60p limit.

    As a G9 owner I'm quite looking forward to the update - and yes, having waited for the G90 to arrive in the market a while back, it wasn't a hard choice to buy a G9 instead, the 4k 50/60 capability and top-notch IBIS is far more important to me than the extended record times of the G90...and I paid less for the G9 than I would have for a G90 ?.

  19. In the UK, Panasonic are now offering £400 cashback on the S1 & S1R family, plus a free Sigma MC-21 Mount Converter (Canon EF to L-Mount) with the body-only versions e.g. an S1 body-only is £1799 after cashback. However it looks like the free DWM-SFU2 firmware upgrade offer has ended...

    Park Cameras and Wex are also offering 10% off the lenses.

    I’m very grateful for the responses. Thankyou. But can you be more specific? You have suggested a lens without explaining how they relate to my needs as I specified. I can’t understand your choice without this. 

     What lenses do you already own?

    It sounds like this is daytime use, so I guess low-light isn't really an issue (and you want in-focus background, so you don't need a large aperture lens)?

    The standard Panasonic 'kit' zooms (the 12-32mm 'pancake', the 12-60mm and various 14-42mm versions) are all fairly 'wide-angle' capable - these are cheap to buy used as they are very common.

    If 12 mm isn't wide enough then you are getting into more serious wide-angle lenses - some possibilities have already been mentioned. Even then, 7-8 mm as about as wide as you can go without it becoming a high distortion 'fish-eye' lens.
