  1. You must be based in Dublin ? So am I.
  2. Get highlight -2 and DR400 for the best highlight roll-off.
  3. It's only possible because of this newly released stacked sensor, IMX383. However, all those relevant readout modes are using 10bit ADC, which would seriously compromise IQ.
  4. This is what the IMX383 sensor is capable of: https://www.sony-semicon.co.jp/products/common/pdf/IMX383-AAQK_Flyer.pdf
  5. https://dronedj.com/2019/11/26/autel-evo-2-specs-drone-with-8k-6k-with-1-inch-sensor-and-thermal-options/ The three user-changeable gimbal modules for the Autel Evo 2 are: 586 gimbal: provides an 8K video camera that will take still photos of up to 48MP and records 8K video at 25 fps, 6K at 30 fps, or 4K at 30 or 60 fps with a bit rate of up to 120 Mbps. 383 gimbal: features an Ultra-HD camera with a 1-inch sensor for 6K video and still photos of up to 20MP. It will record video up to 5.5K at 60fps or 4K video at 120 fps and has an adjustable lens aperture from f/2.8 to f/11. Dual-sensor gimbal: provides an infrared camera that takes infrared images of 640 x 512 or 320 x 256 and records video at 720p at 30 fps in dual image mode. It has the same 8K video camera as described above.

    I was told that 10bit H.265/HEVC codec will be available at official launch. But looking at some raw footage, it just looks oversharpened and mushy with aggressive NR. There are some of the most brilliant engineers on the dev team but adding an imaging expert would definitely be able to take them to the next level.
  7. Non-crop 4K on X-T3 and Z6 has the same rolling shutter at around 21ms.
  8. X-T3/X-T30 already readout and supersample the sensor at 6K 50P.
  9. Seriously for this kind of shoots, X-T3 would be a B-cam, the size and weight of a rig are just unrealistic for dynamic follow shots. A-cam would be a GoPro and a drone.
  10. It'll come with V4 firmware at a later date.
  11. New firmware announcement for X-T3: ■ Firmware update for the X-T3, due to be released in December 2019 Firmware version: FUJIFILM X-T3(Ver. 3.10) Gimbal / Drone support*** This firmware adds the following function to complement the current support for still image shooting via USB communications: Starting and ending video recording Adjusting exposure settings (exposure mode, shutter speed, aperture, ISO sensitivity, exposure compensation) for video recording Making manual focus adjustments ■ Firmware update for the X-T3, due to be released in January 2020 Firmware version: FUJIFILM X-T3(Ver. 3.20) 1. Enhanced autofocus Improving the tracking performance of the eye AF frame, making it easier to attain accurate autofocus on the eyes Improving face-detection performance when there are faces of different sizes within the same frame, making it easier to attain accurate autofocus Improving autofocus capability on a foreground subject even when there is a mixture of foreground and background subjects within a frame, causing the foreground subject to go out of focus, e.g. when shooting flowers against a busy background 2. Capability to save up to 9,999 pictures in each folder Until now, the number of pictures that can be saved in a folder on an SD card was limited to 999. This update will raise the limit by ten times to 9,999 pictures.
  12. You can use Interframe Noise Reduction, since you're not going to film crazy action shots, it'll be very effective in controlling noise.
  13. Correct. But if that’s relevant to what we are discussing here, all films should be shot with just one super wide focal length and just crop in post for different shot sizes.
  14. From a pure technical point of view, 50% of the 65mm mojo is the shift in relationship between FOV and perspective - a 50mm lens mounted on Alexa 65 has a wider 35mm FOV but maintains a 50mm perspective - often described as some kind of grandness or panoramic quality: capturing more without the wide angle look. The other 50% is of course the shallower DOF.
  15. CMOS sensors generally perform the best in daylight balanced source. There are quite a few high quality high CRI LED lights available, like this: https://store.yujiintl.com/collections/high-cri-led-lights/products/led-corn-bulb-for-photography-and-studio-lighting
  16. You're clearly using the wrong LUT. The latest official Canon Log LUT pack from Canon website is "canon-lut-201902.zip" and most of them are tagged version 1.1 or 1.2. And if you use "CanonLog-to-BT.709_BT.709", yes it'll clip like that, this one does not have any tone-mapping. Use the one with "BT.709_WideDR".
  17. Based on my analysis, 4K DNG RAW is oversampled from full 6K readout, this is possible because this so-called "RAW" is already in-camera debayered RGB format.
  18. BS. In terms of colour spectrum, the LCD panel has no effect on the backlight, the panel is literally millions of tiny windows that open or close to modulate the backlight. CFL produces some IR and UV, yes it's broader but they are not in the visible spectrum, and the spikes are all over its SPD. Because our eyes can interpolate colours in between sharp RGB spikes and camera sensor can't, that's a big problem and it does matter.
  19. "Camera sees RGB so it might be fine" - Nah it's not fine. HP, TVLogic and Sony all used RGB LED backlight for their high end products at some point. This is the backlight module with individual RGB LED modules, not RGB pixels in the panel! Old LCD typically have CCFL backlight, it's even more spikey and discontinuous than LED. Quantum dot produces even sharper RGB spikes so non of these are suitable as high quality lighting sources.
  20. Nah. RGB LED backlight was once a very high-end technology reserved only for reference monitors, characterised by three distinct spike in its spectral power distribution. It doesn't have a good CRI due to its discontinuous spectrum, as it's intended to "trick" the human eye which is a tristimulus system (only respond to R, G, B and interpolate everything in between). High CRI/TLCI requires full spectrum light source and some high end white LED backlight can indeed provide.
