  1. Having noticed this post again - a correction: With the recent firmware versions, both the E-M1 II and III support OM-Log400 and Flat profiles in C4K(DCI), UHD and FHD video modes i.e. they are not restricted to just C4K(DCI). Just enable 'Picture Mode' in Menu -> Video Menu -> Specification Settings. I'd love to know why you can't adjust the sharpness in those profiles though...it's blanked out in the Super Control Panel, along with (understandably) the contrast, saturation and gradation adjustments.

    Unfortunately dpreview's video resolution chart tests didn't cover 1080p. What they did find was that 4k 10-bit modes were noticably sharper than the 8-bit modes (except for 4k50p/60p, which appeared to be the same sharpness in 8 and 10-bit) - see https://www.dpreview.com/reviews/om-system-om-1-review#VD I'm waiting to see what video functionality the OM-5 strips out...

    Olympus OM-1

    On the 'Optyczne.pl' website OM-1 'film mode' review, there is a collection of straight-out-of-camera 8 & 10-bit files at the bottom of this page - https://www.optyczne.pl/59.5-Inne_testy-OM_System_OM-1_-_test_trybu_filmowego_Podsumowanie_i_filmy_przykładowe.html The list: Also some resolution test chart videos on this page - https://www.optyczne.pl/59.4-Inne_testy-OM_System_OM-1_-_test_trybu_filmowego_Jakość_obrazu.html Their opinion (Google translated) of the 1080p modes was:
  4. Such sad news, especially involving someone so young - stay strong Andrew and take your time, along with the rest of your family.
  5. The 'Fairchild Semiconductor' that onsemi bought in 2015 was a new version created by Nat Semi selling off their 'standard products' division in 1997, a reasonable amount of which derived from Nat Semi buying the original Fairchild Semiconductor 10 years earlier. As far as I can tell, that 1987 sale to Nat Semi (by then owner Schlumberger) didn't include the imaging division. Via a series of other companies Fairchild Imaging eventually became part of BAE Systems - see https://www.baesystems.com/en-uk/productfamily/scmos-sensors (The myriad start-ups, mergers, takeovers, sell-offs, spin-outs and failures of semiconductor companies over even the 40+ years I've been an electronics engineer would make a pretty complicated 'family tree' I'm sure 🙂)
  6. Given that (as far as I can see) onsemi's image sensor capability mostly comes from buying the image sensor division of Cypress Semiconductor in 2011 for $31 million (based in Belgium) and US-based Aptina in 2014 for $400 million, I think there is a reasonable chance that the Arri sensor was developed in US. As a bit of trivia, onsemi's roots as a semiconductor manufacturer go directly back to Motorola in the 1950s, so it's effectively one of the oldest chip companies in the world. (ON Semiconductor was spun out of Motorola as in independent business in 1999).
  7. Canon, Nikon, Leica and Blackmagic are more than just camera companies - they have other business lines. Of those, Canon and Nikon are probably the most exposed to market changes, due to their historically large presence in the consumer market. Leica, Arri, Red, Blackmagic & Hasselblad are niche players in the overall camera market. I think OMDS has a difficult transition to make into probably a somewhat smaller and more niche player. They do have the audio recorder side of the business as well, but doubtless some of that market has been lost to mobile phones.
  8. That's exactly what's kept me in the M43 eco-system. One of my interests is wildlife photography & video, and the Oly 75-300mm is only around 420g and 120mm long. Combine that with the ex-tele sensor crop capability and IBIS on a Pana G9 and you get the FF equivalent of 1000mm+ lens reach in a combo that fits easily in a modest camera bag or small rucksack (and the oversampled( GH5-level) 1080p on that is so good it's quite close to 4k quality). Take along the 210g Pana 12-60mm lens and that's basically 12mm to 300mm covered in two decent-quality zoom lenses that weigh less than 650g in total.
  9. I think that was inevitable really - why use scarce, expensive component supplies to make low-end, low-margin cameras when you can use them for high-end cameras like the OM-1 instead? Here in the UK, Olympus/OMDS cameras seem to be becoming almost invisible outside of specialist camera stores. The big John Lewis department store chain (which has always had sizeable camera sections in the bigger stores) has recently dropped the brand, despite keeping Canon, Nikon, Fuji, Sony & Panasonic. It'll be interesting to see how 'down spec'd' the video features are in the upcoming OM-5 compared to the OM-1 - I'd love a smaller/lighter camera with 4k50/4k60 capability... (...and OMDS please, please do something about your soft 1080p video - it's embarrassing in 2022 - and why is the OM-1 8-bit 4k video softer than the 10-bit version?)

    It doesn't - 4k is max 30p, and no 10-bit video at all. (With current firmware, E-M1 ii, E-M1 iii and E-M1 X have the same basic video specs - the differences are mostly AF and IBIS performance)

    Not mine, but there are a few 1080p 8-bit and 10-bit clips here, which might help a bit - https://www.youtube.com/user/LexTNeville/videos Also on 'Optyczne.pl' there is a 1080p resolution test movie (I don't know if any of it is 10-bit) - https://www.optyczne.pl/59.4-Inne_testy-OM_System_OM-1_-_test_trybu_filmowego_Jakość_obrazu.html - and some downloadable 1080p samples here - https://www.optyczne.pl/59.5-Inne_testy-OM_System_OM-1_-_test_trybu_filmowego_Podsumowanie_i_filmy_przykładowe.html

    Out of interest, where did you read that? The rumor stuff I've seen is talking about an OM-5 in September/October, which appears to be positioned in the E-M5 iii market segment i.e. smaller, lighter and down-spec'd from the OM-1 but probably using the same sensor. The large body E-M1X always seemed to be an aberration to me, the opposite of the traditional 'small camera body' Olympus ethos, probably driven partly by engineering necessity to get enough cooling for the dual processing chips they needed to improve autofocus performance. It's interesting (from a user demand/popularity point of view) that the used prices in the UK of E-M1X are now lower than for the E-M1 iii, despite it being a more expensive and capable camera originally.
  13. Also remember that if you initiate video recording, with the mode dial in any photo mode it ignores the exposure settings and records in 'full auto' exposure. You can force shutter priority in this situation by using the 'flicker reduction' setting in the menus to force 1/50, 1/60, 1/100 or 1/120 shutter speed, but that's all. I assume (but don't know for sure) this situation carries over into any custom presets derived/generated from photo mode. To get full exposure control for video you have to use 'creative movie' mode on the dial. Only exception to the above is '4k photo' mode, which records 4k video but uses the current photo exposure settings (as it's regarded as a photo mode). As an aside, my Olympus E-M1 ii does basically the same thing, except that it doesn't have the same 'flicker reduction' workaround, so you have to switch to 'movie' mode to get shutter priority for video (which is annoying when switching between video and stills frequently).
  14. As a budget used option, I'd also consider a used Olympus E-M1 mk2 - decent, full sensor width, 4k up to 30p, excellent DCI 4k at 24p (only), phase-detect AF, superb IBIS (probably only beaten by the newer Oly/OMDS cameras), pro-level build quality and weather sealing, mic and headphone jacks, dual SD card slots and great battery life. It also feels good in the hand. I think the 'Flat' picture profile provides better video quality than the normal profiles (there's OM-Log400 available as well). The E-M5 mk3 is essentially the same camera in a smaller, lighter body (but no headphone jack and only one card slot), but is more expensive used. E-M1 mk3 has better AF, an AF joystick and auto-ISO capability in manual video mode, but is rather more expensive used. I own the G85, G9 and E-M1 mk2 - G9 has the best video quality (including 10-bit support) and the best EVF, but the E-M1 mk2 is a great all-round package at the current used prices.

    ...also GH6 images are now available in the 'Video Stills Comparison' tool - this is OM-1 UHD 10-bit versus GH6 UHD and OM-1 UHD 8-bit versus GH6 UHD (it doesn't say if the GH6 images are 8 or 10-bit video)
