  1. In the photography stills world nobody talks about color science. Nobody says Panasonics jpegs are better than Canon or Sonys. That is because people are shooting 12/14 bit raws and you get to choose exactly what colors you want. I sort of feel in a 10 bit world straight out of camera colors are simply less important because you get so much more leeway to create the colors that you desire. Of course there will be always be people who like to shoot jpegs or straight out of camera video but then you dont really need 10 bit at all.
  2. As a Sony user, I can say that it has been pretty easy to overheat the last 3 Sony A7 cameras I have bought - particularly the A7r3 - when shooting 4k 30p video for any length of time. As such, the A7siii seems to be something of an improvement from what I have read even though it clearly does overheat in some instances. Sony were clearly asking for trouble though by stating that that it wouldnt overheat. Overall though my theory is that Sony didnt really take the 'high road' but the Canon decided to take the 'low road'. Canon probably reasoned that if Sony can put out cameras that 'overh
  3. Sony is not really in the business of selling 'cameras' but 'image sensors' - a business they dominate and until recently couldnt make enough of (smartphones now often have 5 image sensors when 10 years ago they had 1 or 2.) https://www.bloomberg.com/news/articles/2019-12-23/sony-can-t-make-image-sensors-fast-enough-to-keep-up-with-demand The camera business is simply a halo product for this business where they can show off their latest tech and be at the forefront of this business. The camera business doesnt really have to make money itself if it is promoting their image sensor busi
  4. On the A7siii - is it confirmed that 1080 120fps is pixel binned/line skipped (or both)? (Androidlad pointed this out.) I keep on reading reviews saying it is down sampled from 4k
  5. Looks like Canon made a marketing mistake, focusing on video specs - where the camera clearly has some drawbacks. As a stills camera it looks to be very impressive indeed.
  6. Going the same route. Have an A7riii and A7riv. Will sell the A7riii and buy an A7siii. Will be set for a couple of years....
  7. The Sony has an overheating cut off setting which is normal by default but can be set to high. Probably explains the different overheating results to some extent.
  8. In the latest Sonyalpharumors post there is a feature listed as: * Movie Edit add-on compatibility for Image Stabilization in post Does anyone know what that means? At first I thought it meant no IBIS but the photo shows 'stabilisation inside' written on the camera in the same place as the A7riv.
  9. I dont agree. Sony has a range of 'hybrids' from the A7riv to A9ii to A7iii to A7siii - they all make various compromises from the A7riv that is a photo camera that does a bit of video through to the A7siii which is a video camera that can take photos. Clearly if your passion is 'printing big' you dont go with the A7siii. At the end of the day the A7siii should and will be judged on how good it is at 'taking video' - IBIS, AF, resolution, frame rates, bit rates, overheating etc....
  10. The killer feature the A9 and A9ii have is 'silent shooting with a stacked sensor' - this means you get silent shooting with a very fast sensor read and no noticeable rolling shutter in the stills. Contrast that with say the silent shutter on the A7riv which is basically unusable (apart from still scenes) because of the rolling shutter. Canon and Nikon are yet to introduce mirrorless cameras with a stacked sensor. As for the lack of SLOG and other picture profiles on the A9, I thought it was a tech limitation of the shutter on the A9 rather than a software/cripple hammer issue?
  11. I am pretty happy with the specs so far. Will pair nicely with my A7riv. Would like much improved video IBIS but am not particularly hopeful.

    My webcam is rubbish. Well, actually its the webcam video that looks rubbish. My webcam is the popular Logitech C920 - which as webcams go - is a mid/high end webcam. But the image out of it really is bad (especially in low light.) And, in case you are wondering - no, I dont have anything better to do than wonder why the video out of my webcam is so bad. Watching the news when everyone is being interviewed by webcam, you realize that virtually everyones webcam is crap. And it isnt just my lighting. Admittedly my lighting was bad but I bought myself one of those Elgato key lights - be
  13. Olympus's camera division has been bleeding for years. To translate those yen figures into dollars - over the past 2 years imaging has lost US$270m dollars on US$800m of turnover. Rather remarkably this doesnt include corporate/central allocated costs that are a seperate line item (to the divisions) in the accounts. Even more remarkably, if you go back and look at when the division reported a 'gross profit' you will find that the gross profit margin was around 50% (which is quite lot higher than Apple's). You really dont get a lot of camera for your money even when the company is losing U
  14. 'Honest advertising' is an oxymoron. The entire point of modern corporate marketing is scientifically crafted deception. Camera companies starting up a fund to pay a bunch of different people and create a different bunch of shills. If you can trick people into thinking your trickery is honesty, you can trick them even better. Thinking of Olympus - at least keep it humorous.
  15. Sad - the OMD EM5 was my first digital camera - but inevitable. Olympus's camera division has only made a profit in one of the last 12 years. It is a pale shadow of what it was - back in 2008, the camera division reported over US$3bn of sales (mostly compacts). Now it is less than US$400m.
  16. Yes, sunk cost fallacy. Realistically, your crowd in 'crowd financing' is self isolating at the moment. Even those with disposable income will likely be saving it in the current uncertainty. And if they are looking to invest (and or take risk) there are plenty of stocks that are off 40% in the last month.
  17. I get that totally. But what I mean by behind the curve is - why has it taken the country so long to start testing people in large numbers? We have known about this virus for quite some time. I live in a 2nd world country - Thailand - but it has been possible for anyone to get a test here, if needed, for well over a month....
  18. It does appear to me that the US has been well behind the curve on this virus all along which is disappointing given the amount of advance warning they had. Today the US announced 1823 new cases which is a 40% increase in cases from the day before (the largest percentage increase of any country.) https://www.worldometers.info/coronavirus/ Hopefully they will get things back under control quickly...
  19. Have you considered the 'worst case' scenario? Well it turns out that the NHS in the UK have modeled the worst case. https://www.theguardian.com/world/2020/mar/15/uk-coronavirus-crisis-to-last-until-spring-2021-and-could-see-79m-hospitalised Under this scenario it is assumed that 80% of the UK's population contract coronavirus over the course of the next year. According to Chris Whitty the UK's Chief Medical Officer this could lead to 7.9m people being hospitalized and 318,000 deaths. Whilst this figure sounds (and is) horrendous it needs to be put in perspective. In 2018 there
  20. Well on a more positive note. We can see from China and S.Korea that when you tackle the problem head on with tests and restrictions you do seem to get it under control within a month to 6 weeks - hopefully numbers in Italy will start to come down. Also a major panic in the asset markets, should mean we get some great investment opportunities for those that have some cash....
  21. There is minor panic here in Bangkok. Most people are wearing masks (despite the fact that they are effectively useless for preventing you catching Coronavirus). The schools have all been shut. My 6 year old son had to self-quarantine for 14 days when he returned from a holiday in Japan. I had dinner with a friend who has a birds nest business and in February sales were down over 90% compared to January. (In China, car sales are down 83% for the first two months (YOY)). And this is despite the fact that Thailand has only had 40 cases of Coronavirus so far (mostly Chinese touris
  22. I rather suspect the simple answer to this dichotomy is that 'youtuber, actor, singer, programmer' etc were not 'career/job' options in their survey...
  23. For me Portrait of a Lady on Fire’ should definitely have been nominated for cinematography.
