    Hey now, 300nm used to be a cutting-edge process... all the way back in 1996 or so, but it was certainly cutting-edge back then!

    (To be fair, 90nm processes aren't exactly new either - they've been around since roughly 2004 - but still, quite the difference)

    For a 36x24mm FF sensor, 300nm vs 90nm process really make very little if any difference to image quality. There are more important contributors.

    CMOS sensors are not CPU, there's no constant need to shrink the die.

    Hi,

    Thanks for this. I'll take that support non-native, as an add-on, but is this only on the Lab?  The motors wouldn't work with the Crane 2?

    Desk

    Crane 2 has its own focus motor, while Crane 3 Lab/Weebill Lab have their own motors for both focus and zoom, at the same time.

    Does anyone know if there's a gimbal which allows follow focus and zoom control support for the XT3?

    Desk

    Zhiyun Weebill Lab/Crane 3 Lab support it, by providing two motors for zoom and focus control.

    Please post photo examples. 

    And the reason I ask is I just shot an entire short at an open field/horse barn and graded the entire project using GHALEX and there is not one trace of banding. Not even in the outdoor shots going directly into a blue sky, all the way to a way underexposed inside the barn office and even then it was just fine. 

    Even before on the old thread, I was unable to make my Fuji's footage band at all. I am coming from shooting on Sony's.. so I know what banding is! Is it entirely possible that you have a bad copy? I have googled and googled and you are the only person I have found that has issues with banding on a Fuji system. Every search I have done for it has brought up issues with photo and the ES, but nothing for the 10bit video. 

    I've seen a couple complaints regarding F-log banding/blocking on DPReview forum. Most people don't care though, not everybody is an image quality purist.

    Doesn't look like a hardware problem so bad copy is very unlikely.

    I don't know if this has been addressed here but I'm finding some issues with flog with the xt3. Has anyone experienced these "pink splotches" before? These were shot in 10bit H.265. I'm finding that the HLG doesn't suffer from this issue. I placed a lut to emphasize the issue. Any help would be appreciated!

    Yes this issue was discussed extensively on this forum, see my post comparing F-log and HLG. There's something wrong with Fuji's F-log implementation, could be flaws in the encoding parameter. The solution is to shoot HLG instead, it's completely clean and in my opinion also offers better colourimetry than F-Gamut.

    Please report this issue to Fujifilm by sending these photos along with a description http://www.fujifilm.com/contact/

    We have to get Fujifilm's attention for a possible fix.

  6. Observation from preliminary testing GHa on X-T3:

    With F-log, even at 10bit 400Mbps, applying two LUTs (F-log to V-log then GHa linear) produces noticeable banding in the footage. The F-log banding issue was discussed in other threads but using two LUTs really accentuate these artifacts.

    HLG works amazingly well, the GH5 HLG preparation LUT is a perfect match (BT.2100 HLG is a standardised colour space so shouldn't come as a surprise). Again as discussed in another thread, HLG on X-T3 removes the magenta hue. Shades of blue have that Alexa signature cyan tint.

    Similar architecture to the Sony-Fuji 100MP medium format sensor?

    Personally I don't need 100MP stills but the technology is interesting as is all forward progress, it leads to an interesting future and is better than staying the same, otherwise we'd all be shooting 720p and 8MP stills

    Almost completely different architecture with this one being more advanced. 3.76um vs 2.91um, slim DTI, way more ADCs and they are now colour-aware (meaning significant readout noise reduction and QE boost).

    There are various 2x2, 3x3, 6x6 binning modes optimised for speed, quality or a compromise between the two.

    One of the 2x2 binning modes produces a 25MP image that even surpasses A7 III.
