    rawshooter got a reaction from austinchimp in Fuji H.265 vs Blackmagic Pocket 4K ProRes 422   
    ProRes is factually a derivative of MPEG-2, that's why it's so light on CPUs. It compensates its old codec technology through high bitrates, thus the generally good quality.

    h264 and h265 will always be better than ProRes at the same bitrates, provided that a decent codec implementation (with high profile and 10bit color depth) is being used.
    So the question is whether 400 Mbit/s h265 (in the case of the Fuji XT-4) for 4K/25p video is visually as good as ProRes HQ at 737 Mbit/s for the same resolution and frame rate... 
     
    EDIT: The real issue with h264 and h265 are not the codecs themselves, but that manufacturers - treating them as consumer codecs - bake all kinds of overdone image processing (aggressive denoising, artificial sharpening, pushed contrasts) into material recorded with them. ProRes, being conversely treated as a "pro" codec, doesn't get those over-processed images. This is why we think that ProRes is better...

    rawshooter got a reaction from Sharathc47 in What next for Sigma? What would you like to see?   
    My wish list:
    Either bring the electronic shutter of the next fp to the performance level of the Sony A9 or add a mechanical shutter to make the camera more usable for stills photography, too. Get rid of the 0.1s shutter lag. Implement compressed CinemaDNG in non-US regions where RED's patents don't apply; in the US, simply block them in firmware. With compressed CinemaDNG, 6K RAW image recording could even work on SD cards. Implement Log, and apply the Log curve to 10bit and 8bit RAW so that its recorded values are more sensibly distributed (and the material can be better graded without falling apart). Work with software manufacturers to have the Log curve supported in their programs, including Resolve and its "Color Space Transform" function. Provide IDTs for ACES. Replace the back wheel with a more solid wheel that stays in place and doesn't accidentally rotate. Replace the AEL button with a wheel that can be pushed in - so that there would be 3 wheels in total, for shutter, aperture and ISO control, or alternatively audio level control. Allow simultaneous focus peaking and zebras, and focus magnification during recording. Replace, if possible, the micro HDMI port with a full-size HDMI port. Make the "Tone" and "Color" buttons user-definable. Make the photo shutter button user-definable in cine mode and vice versa. Stick to the same, tried-and-tested Sony 24MP FF sensor.

    It is a very basic, stripped-down camera.

    (No EVF, no mechanical shutter, only two dials and only one customizable button, no Wifi, no Bluetooth, no IBIS, no phase-detection AF, no high flash sync speed, no dual SD card slots...)

    Yes it is a disgrace.
    But that's often what happens when sales, accountancy and marketing department staff are expedited to the top of the camera over the heads of senior engineers.

    It's really a pity that Olympus threw decades of its expertise in making compact and optically brilliant FF lenses out of the window when they switched from analog to digital. I agree that they could have had a brilliant future as an all-systems lens maker (instead of a single-system camera maker).
    Manual focus OM lenses are still among the best vintage lenses you can buy and adapt to your camera, since their optical formulas were optimized for compact size, low contrast (=high DR) and high resolution.

    It's a f*ing disgrace for the legacy of Yoshihisa Maitani, Olympus' genius camera and lens designer (who created the original analog Pen/Pen F system, the original 35mm OM system, the fantastic Olympus compact rangefinder cameras and the brilliant Olympus XA).

    The G100 is a pretty clear indicator that Panasonic is putting no more significant development into MFT. It's just recycling old components, including the PCB - the camera still has USB 2.0...
    I wouldn't expect the GH6 to get more than a CPU upgrade (with the same current-generation ASICs developed for the full frame cameras), but otherwise the same electronics and maybe even the same sensor.

    This is unfortunately no longer true for fully electronic mirrorless lenses - which not only depend on system-specific protocols to function at all, but also heavily rely on in-camera digital geometry and vignetting correction. 
    When a mirrorless system falters, you can pretty much throw away the lenses. (As it happened before with Nikon 1 and Samsung NX.)

    The main problem with the camera's RAW video still persists, even with external ProRes RAW/BRAW: It doesn't record a pixel-to-pixel 6K sensor image, but scales down the RAW from 6K to 4K - so that you get a pseudo-Bayer pattern with all kinds of visual/line skipping artefacts.

    Just installed and tested the firmware, with the following results:
    - CinemaDNG recordings now have proper synchronized audio in Resolve, but Resolve still doesn't recognize them as CinemaDNG sequences, only as DNG stills sequences with attached audio. I.e. it does see them as clips, but only as folders containing DNGs, and you need to recursively import them ("Import folders and subfolders").
    This also means that you cannot use Sigma fp's CinemaDNG in the Cut module.
    - In stills mode, the 0.1s shutter delay is unchanged. (Which also means the image you see frozen on the display after pressing the shutter is not the image that gets recorded/stored - you can test that by shooting a digital stopwatch.) So I guess this is a hardware issue and unfixable. 😞

    Jip is not a company that will continue building cameras or lenses - they buy up brands like "Vaio" from Sony to sublicense them for cheap no-name products.
    The brand Olympus will stay with Olympus for the (now) core business of medical equipment.
    Olympus imaging brands such as OM-D, Zuiko and Pen will soon appear on smartphones, selfie sticks and the like, ending up like Polaroid and Rollei did before.
    Olympus' camera technology is now history, like Yashica/Contax in the past.

    IMHO, nothing beats the Godox SL60W if you want a cheap light with good light quality/color rendition, and one that works like a proper film light (with optional fresnel lens, beauty dish, soft box) which can be used as both a hard and a soft light.
    So far, it has completely been in a budget-vs-quality league of its own, like only few other pieces of video gear. (Others would, for example, be the Canon EOS-M with MagicLantern RAW, the Rode Video Micro and the Sigma 17-50mm/2.8 zoom lens).
