  2. 1. The pixel-level read node design is similar to IMX610, only the implementation is different and dictates that it has fast conventional read speeds. 2. The physical pixels are 49 megapixels and the entire sensor is natively designed to be 49 megapixels, reusing the 4.2um BSI pixel design and using both analogue binning and digital binning together to achieve a 12 megapixel sensor. 3. IMX510 disables the all-pixel readout mode, so there is no possibility of an all-pixel readout, and naturally it cannot achieve 2x2 OCL AF, which is the biggest difference between it and IMX472. 4. Dividing IMX510's logical pixel into four physical pixels. The readout is achieved using 1:2 analogue binning before PGA and digital binning after ADC. The specifics are: A. 48 physical megapixels, divided into upper left, upper right, lower left and lower right in-group pixels. B. 24 mega pixels are read, binned in the form of upper left + lower right, upper right + lower left, dual stream 14bit readout. C. 2:1 pixel binning in the digital domain to generate 12 megapixels at 15bit, discard 1bit to 14bit output. D. The readout speed is around 21ms, approximating 48fps; when the precision is reduced to 12bit, 96fps can be achieved. E. The ADC does not have an 11bit mode, so it cannot achieve the faster 24M 11bit -> 12M 12bit. F. The digital binning discards 1bit of precision regardless of the mode of output, a waste of performance deliberately designed into IMX510. G. In one video mode, the internal readout of two 3.84K/128fps 12Bit ADC streams are digitally binned, but the resolution is not twice that of 3.84K. The precision and resolution are wasted. 5. Due to the uniqueness of the readout mode, IMX510 cannot achieve any 2x1 OCL in-group AF, and the orthogonal readout pixel groups cannot be used for phase detection. Therefore the only phase focusing design for the IMX510 is masked PDAF. A focusing method using 2x2 OCL AF will only be available when the all-pixel readout mode is unlocked. 6. The hardware performance of the sensor goes well beyond the limitations of the "IMX510" name. 7. If this sensor were to be a normal Bayer sensor, the readout speed would depend only on the total number of analogue pixels before the ADC, due to the pixel readout design. Thus 48 megapixels at 24fps 14bit. For this a Modified Bayer CFA can be used, which is suitable for pixel designs with 2:1 analogue signal binning - maximising its performance and enabling dual mode switching between high resolution and oversampled high speed shooting: Crop to 16:9 to achieve 8.5K/57.7fps 12bit, 2x4.35K/115.5fps 12bit respectively; crop slightly to 7.68K/64fps 12bit, 2x3.84K/128fps 12bit. Notably, its 2x3.84K/128fps 12Bit readout truly has double the resolution and achieves IMX301-like oversampling performance (Sony F65RS). 8. The readout speed of any column-parallel ADC design of an image sensor must be scaled by the line readout speed, by the total number of pixels multiplied by the number of columns, and at the same level of precision comparing: A 48 megapixel 14bit 24fps sensor reads at a larger scale than a 12 megapixel 14bit 48fps sensor, but we cannot call it a greater total number of pixels read out, but rather a faster readout, measured by miliseconds. At a given precision, readout time (the time taken to read a frame), readout scale (how many pixels are read in a second), and readout speed (how many rows of pixels can be read in a second by a column of ADCs), are three dintinctly different and important metrics.

  3. I agree, it is a great setup.

  4. I wholeheartedly agree, and I wish I had done that with my original post. My original point was that natively, when looking at the RAW files, downsampled 1080p doesn't look much softer than native 4k. The difference is small enough not to matter unless viewed side-by-side. The difference is small, and as a result one can use a tiny Atomos Ninja Star with a Nikon Z6 to gain 10 bit log without needing a large bulky external recorder/monitor, thus making the Z6/Star combination very compelling given the price.

  5. I was hyperbolizing it a bit but what I said is true to an extent. 4K to 1080p is what you do when you are playing the file locally but uploading to Youtube it's better to leave it as 4K and add a slight NR to it.

  6. Recently posted over on reddit what is the best prosumer wireless on a budget, which is the Sony UWP-D21, and why. Thought I'd reshare it here as well, should others here be interested as well: --------------------------------------------------------- If someone can't afford pro level wireless (i.e. a receiver such as the Wisycom MCR54 / Lectrosonics DSR4 / Sony DWR-S03D / Sound Devices A20-RX / Shure ADX5D / etc plus the appropriate matching receivers) then going instead with the fourth generation Sony UWP-D is no brainer decision! (although, I'd recommend 2x UWP-D21 over 1x UWP-D27) This choice is so easy it isn't even close, as the 2nd best choice comes a long long way behind Sony. Sony gives you: True diversity receiver (no other prosumer UHF wireless has this) Has a digital compander (avoiding the issues that say for instance the Sennheisers have with their analogue compander, giving you better quality audio from the Sonys. Essentially, the Sony wireless transmission behave more comparably to how Lectrosonics Digital Hybrids do, using the same mix of digital + analogue for transmission) A slot receiver (again, no other prosumer wireless does this! Although, sadly not unislot, you'd need to get the Sony DWR-S03D instead. Hopefully Sony will bring out a UWP-D receiver one day in the future with unislot compatibility) An option of using the smart shoe on Sony cameras to feed it audio directly, skipping doing another D/A conversion, along with numerous other benefits such as being able to add more audio channels than otherwise or being able to go cableless with the receiver or not needing to do battery changes either for the receiver (these are all features entirely unique to the Sony wireless) Sony UTX-P40 Wireless Plug-On Transmitter supplies phantom power. (the Sennheiser EW100 G4 plug-on transmitter does not) Headphone output (but yet again, the standard Sennheiser G4 doesn't have this) An option for a dual receiver (again, the Sennheiser G4 doesn't have this) An option for getting it in the 941 to 960 MHz frequency range (again, the Sennheiser G4 doesn't have this, Usually only pro wireless offers products in this frequency range) Backwards compatible with all past UWP products. Just a few of these reasons would be enough to make a strongly compelling case to buy the Sony UWP-D21! (especially as Sony is priced similar to or cheaper than the Sennheiser competition) But add them all up together? Sony blows away all the competition. There are literally hundreds and hundreds and hundreds of options for lav mics for the Sony wireless just merely listed on the one B&H website alone: https://www.bhphotovideo.com/c/products/mini-microphones/ci/3779?filters=fct_compatible-with_744%3Asony%2Cfct_connector-type_745%3A3.5mm-mini-plug|3.5mm-mini-plug-locking There are zillions of accessories for the Sony UWP-D system, such as these (would you like for instance a battery pack for your Sony transmitter so that you can run it for over 24 hours? You can do that!!): https://www.hlaudio.de/sony-pro-audio/wireless-zubehoer/ Unfortunately when people hear "Sony" they think of "cameras", not audio. What most people don't realize is that Sony's name itself comes from the latin word for audio: "sonus"! Sony originally started out as purely an audio company, and has been making wireless since the 1950's.

  7. Plus you get a lot of popular 2022 convenience features at a very low price point. You really canโ€™t get full frame 10 bit PDAF and IBIS for this cheap otherwise

  8. Yeah Kye I never got that from your posts. My whole point was that downsampled 1080p looks very similar to 4k even when viewed on a 4k screen, and because of that fact, the Atomos Ninja Star makes the Nikon Z6 a pretty great camera in 2022, as you get a great image but much less inconvenience compared to most external recorder/monitors.

  9. I'm trying some really cheap Chinese lights. I actually found one really good 300W but unfortunately it only works with 220V - so if you're in 220V land look up ZSYB LED on ali express ~ $180USD!!! Comes with remote and the metrics with my C800 read very good, nanlite and aputure level. Fan is also quiet - amazing! I bought a 110V>220V transformer and it works. Only works on half power here with 110V ๐Ÿ˜ž Ordered a different one to test that is even cheaper but works with universal AC ๐Ÿ˜„ still in the mail. I have a 4x nanlite FS300 array which was amazing at the time for price/performance with the fan mod, but on a recent shoot wanted even more lights, found even cheaper lights now ๐Ÿ˜„ Am looking forward to a cheaper 600W fixture, but the current crop of 600/1200Ws are that they are overbuilt for mass market and quite heavy, 4x 300W are lighter and cheaper and take up less space so it's hard to justify getting a 600W/1200W unit, way more $$$, heavier, and takes up more space... I'm thinking at least 3 more years before we see any of the cheaper bigger boys that are lighter.

    OK, I just popped outside the back door and pointed the camera at a street light at night at base ISO 250 and DR Boost 2000 and there was no streaking visible in the viewfinder. Honestly, it's such a non-issue. Don't let it put you off. Like I said, I had totally forgotten about streaking until now, because I simply haven't seen it since the time I succesfully attempted to reproduce it.

  11. The latest I've heard if from an interview a couple weeks ago. Around the 9 minute mark: https://www.youtube.com/watch?v=mY672OZBrp0 He says they are in the middle of the second stage, and hope to begin the third stage by the end of the year or early next year. Camera body design won't happen until after the third stage. I wouldn't expect it until late next year at the earliest. I just hope it allows for some sort of video capture, especially if it can be CDNG like their fp system. foveon+cdng would be the closest thing to film in my opinion.

    Yeah, I've read about the mixed results, so I am not sure. I don't know if the original dcc17 can be connected to a powerbank, or if it can be connected only to a wall socket.

  13. Maybe too obvious, but what about the EOS M with ml in 2.5k (or 2.8k) crop? The cheapest alternative atleast.

    You'd take the Tamron 20-40mm f/2.8 over the Tamron 11-20mm f/2.8? You don't ever need anything wider than 17mm? Do the Tokina / Viltrox / Sigma sets of fast f1.2/f1.4 primes for APS-C appeal to you? They're very affordable! https://www.bhphotovideo.com/c/products/Mirrorless-Camera-Lenses/ci/17912/N/4196380428?filters=fct_a_focus-type_5738%3Aautofocus%2Cfct_brand_name%3Atokina%2Cfct_lens-format-coverage_3332%3Aaps-c-lenses%2Cfct_lens-mount_3442%3Asony-e-mount%2Cfct_zooms-primes_5903%3Aprime-lenses https://www.bhphotovideo.com/c/product/1723065-REG/tokina_szmf33_fe_sz_33mm_f_1_2_mf.html (I'm guessing more are coming soon? To fill out the set?) https://www.bhphotovideo.com/c/products/Mirrorless-Camera-Lenses/ci/17912/N/4196380428?sort=PRICE_LOW_TO_HIGH&filters=fct_a_focus-type_5738%3Aautofocus%2Cfct_brand_name%3Asigma%2Cfct_lens-format-coverage_3332%3Aaps-c-lenses%2Cfct_lens-mount_3442%3Asony-e-mount%2Cfct_zooms-primes_5903%3Aprime-lenses https://www.bhphotovideo.com/c/products/Mirrorless-Camera-Lenses/ci/17912/N/4196380428?sort=PRICE_LOW_TO_HIGH&filters=fct_a_focus-type_5738%3Aautofocus%2Cfct_brand_name%3Aviltrox%2Cfct_lens-format-coverage_3332%3Aaps-c-lenses%2Cfct_lens-mount_3442%3Asony-e-mount%2Cfct_zooms-primes_5903%3Aprime-lenses (I feel like Viltrox has the best range of AF APS-C primes for Sony E Mount, unless splurging out for the Sony branded lenses) Or TTArtisan which has lots of fast primes for Sony APS-C that are sub $100! ๐Ÿ˜ฎ (although, of course, they're only manual focus) https://www.bhphotovideo.com/c/products/Mirrorless-Camera-Lenses/ci/17912/N/4196380428?sort=PRICE_LOW_TO_HIGH&filters=fct_a_focus-type_5738%3Amanual-focus-only%2Cfct_brand_name%3Attartisan%2Cfct_lens-format-coverage_3332%3Aaps-c-lenses%2Cfct_lens-mount_3442%3Asony-e-mount%2Cfct_zooms-primes_5903%3Aprime-lenses oh just realized there is a nifty Meike 12mm f/2 Lens for Sony E at only $199! Of course with a MFT level "crop" in 120fps UHD, that's no longer ultrawide, but it is still a nifty wide angle lens with a fast f2 aperture for very little money! https://www.bhphotovideo.com/c/product/1714074-REG/meike_mk_1220cfmf_e_12mm_f_2_0_aps_c_manual.html (or go 2mm wider for more than double the cost! With the Meike 10mm f/2)
