  1. Yeah, I know! Some criticisms just need to answered by telling the people to get a grip ???
  2. The paid version has both spatial and temporal noise reduction. I am pretty sure the temporal NR isn't in the free version but the spatial one might be. There's a bunch of plugins with the free version and a whole bunch more with the paid one. Plus everything that's in Fusion which seems to be enormously complicated and thorough.

    Now there's a terrifying combination of words I've never heard before!! In other news, I just managed to score a good deal on a Lomo T-43 40mm f4 lens. At ~$5 including shipping you really can't complain that it doesn't have focus controls or even a mount that you can buy adapters for, so you have to make your own. On my GH5 it'll be 80mm equivalent, and will be competing with my much more expensive 55mm 1.8 Super Takumar and 0.7x focal reducer combination, but in a sense this might be more fun. My plan is to do some free-lens tests and then if it's worth investing in I'll adapt it with the ~$25 for the helicoid adapter, mount adapter, and glue that you need It might be useful to have such a small lens for 80mm - in situations where you want to keep the setup light-weight or compact.
  4. Oh yes, sorry - forgot you're the OP for a second there! I could argue that starting a thread here is inviting the random and that you should have known, but I'll let you off with a warning this time, but don't let me catch you doing the same thing next time and claiming it wasn't intended!! ???
  5. Yes. Of course, if you think of AI as the automation of thinking, then it fits with robotics, which is the automation of doing. Then you can understand what AI will do by looking at what robotics has done. Robotics has provided three main impacts: it replaced some jobs outright, it de-skilled some other jobs, and it means the owners of the machine get more of the profits. This is reflected in the current trends of there being some unemployment, but considerably more under-employment where skilled workers are forced to work unskilled jobs for less money. The rise of AI will have pretty much the same impacts, but it will do it to intellectually repetitive tasks instead of physically repetitive tasks. We're going to cause an enormous shift in the workforce and that's where the arguments for basic income are coming from. There's been a steady reduction in the number of hours worked per capita over the last 50 years (IIRC - it's multiple decades anyway) due to banning child labour, the 40-hour week, and other social changes, so automation and AI are just continuations of this trend. In the longterm, we're just not going to have enough jobs, so we need to work out how to cope with this.
  6. That is hilarious! Just what I needed first thing in the morning - a good chuckle LOL. During my uni days I had one of those long conversations that ended up following logical tangents to illogical places, and we ended up designing a sarcastic and borderline-abusive artificially intelligent personal assistant. It would be shaped like a key fob and it would do everything a PA would do, basically like a smart-phone minus the social media. During the early parts of the conversation the design was helpful, it would take notes, make appointments by talking directly with other AIPAs, order goods, etc. Then we figured that the market would eventually be saturated with competing products and that's where the sarcasm would come in - as a differentiator. Things like: "Am I busy next Thursday evening?" "Yes, you are....... I don't know why you bother, but sure" "What about Friday night?" "I'm confident you can fritter that away somehow" "Make an appointment for dinner with Suzy Friday night" "Hope springs eternal" "What am I doing after that?" "Regret... Self-loathing..." But you're right, we can get started now on the current technology ???
  7. Isn't that because most people who might entertain that thought combination are too afraid to voice it, and those that do have their megaphones taken away?
  8. Cropping in and panning / tilting / Ken Burns-ing is a digital simulation of a fixed position camera movement, like a fluid-head on a tripod. The difference is that you don't get the depth effects of the foreground moving differently to the background. If there's a movement towards or away from the subject then you also get a change in how out-of-focus the background is. Nice work! Those movements are complex and really interesting. I don't know your style or what you're trying to achieve creatively but this could really add to the right project. The key is to practice and get to terms with the feel it creates and then use it on the right projects. It reminds me of this video that was posted recently about hand-holding and camera movements, especially the combining of multiple shots into a single moving shot. Also, films with "one take" like Russian Ark where the film includes all the normal shots of a film like close-ups, mid-shots, wides, etc but does so in a single fluid movement. Obviously this isn't as extreme with your setup, but that is a whole aesthetic and would really contribute to the right projects.

    Also remember that you're comparing footage from those cameras through the compression of YT or Vimeo, unless you download the 4.6Gb file of the video @HockeyFan12 shared above. This may or may not be relevant depending on how your project will be distributed and broadcast.
  10. It's just one of the cornucopia of ways to avoid a real debate or discussion. Unfortunately, most people either don't know enough about how to debate properly or don't care enough about doing it properly, so most conversations are just riddled with dirty tactics and are almost completely devoid of genuine logical arguments. Here's an interesting list that contains 71 intellectually dishonest tactics: https://johntreed.com/blogs/john-t-reed-s-news-blog/60887299-intellectually-honest-and-intellectually-dishonest-debate-tactics But there are simpler tactics that are also very common. A great one is shifting the burden of proof. My kids do this all the time and its difficult not to fall for it. They are rude and sarcastic, you call them out about being rude, they deny being rude and instead of justifying that statement they ask "how is that rude" and try to set the context that if you can't prove it then they weren't being rude. Of course, if you fall for the trap and try to provide reasons they just disagree without any argument or proof, and of course they're never going to admit it, so you're flogging a dead horse. I don't think I saw it in the list of 71 tactics in that article. Amusingly, the author of the above says there are only two intellectually honest tactics:

    Why not just put the ef to Fuji adapter on the Fuji, and the ef to MFT adapter on the bmpcc4k, then just treat them like they're ef mount cameras?
  12. Maybe you missed the other 90% of my posts where I was also talking about armed resistance? I mean, you can avoid a real conversation by quoting a small fraction of what I said and then reply only to that if you'd like, but don't think I, or anyone else, wouldn't notice
  13. In a sense I think this is a mostly useless conversation. The value in the conversation is people learning about how other people shoot and the technical aspects of the situation, but I doubt that anything we say here will influence what we're actually given. In a sense, there are only two markets. There is the cinema market who want things like high bitrate codecs / prores capture / RAW, and consumers who want resolution and manageable file sizes. As more and more people are making video professionally and the tech advances there are a few manufacturers who concentrate on providing higher quality capture to non-cinema market segments. Mostly this is Panasonic with the GH line, BlackMagic with the Pocket 4k, and now Atomos as a bolt-on solution. Even if you want higher quality 4K, and for some reason you're not willing to get it via the Pocket 4K or external recording, 8K consumer codecs are actually a good way to get it. 8K is good because: Compressed 4K is lower quality than compressed 8K given the same bitrate (I have done tests and encoding the same material at the same bitrate and 1080 > 720 > SD) 4K displays are true 4K but 4K cameras are only true 1080 after debayering.. to get true 4K after debayering requires an 8K sensor Even if the bitrate for your 8K camera is low, for scenes where things don't move much (eg, people sitting and talking) the IQ will be quite good Even if we're talking 8K on a small sensor, if you use enough light then at base ISO your 8K image will be very nice. This might mean spending more on lighting, but it's not that great an investment and having more lighting is probably a useful thing to have anyway. If you're shooting in natural light then it'll be free. We use ND filters all the time because we have too much light! Downscaling 8K to 4K is a great noise-reduction technique and will be completely free, and won't have any of the strange effects of "smart" NR algorithms 8K will mean you need a more powerful computer, but if you're shooting 4K at higher bitrates and/or doing much grading in post you already need to use proxies to edit and grade anyway, so it might take a bit longer to render proxies and export but that's perhaps the only price you'll pay.

    I'm learning that MFT is actually both here and there.. Getting fast wide lenses without paying a fortune seems to be really difficult, but on the other hand the longer lenses are cheap, fast and plentiful. One thing I didn't realise is that longer lenses have a much shallower DoF than wider lenses, even at the same aperture. This means that if I want to match longer lenses to shorter ones, then a 50mm f2 lens can easily match the same DoF and with a SB be an 70mm or without a 100mm. I also did a quick test and found that my 17.5mm f0.95 needed 1/50 but my 58mm f2.8 on a 0.7x SB only needed 1/200 for the same scene. I'm not sure if this extra light gathering is normal of if I stuffed something up, so I'd be keen to hear from other people on this.. It's also pretty easy to get seriously long focal lengths if you're into wildlife or sports photography. The other major advantage of adapting is that you can pick whatever lens from whatever system, so in a sense all the battles between the manufacturers about pushing under-featured bodies to people already invested in your lens system is completely irrelevant. Yeah, if you spend a couple of hundred on a SB then you're kind of invested, but if you're looking at adapting lenses at the longer end then you can just buy a $15 adapter for each lens and forget about which system they come from. I was looking at a page the other day talking about the Helios 58mm lenses, and was saying that the model number is in the format of Helios 44-X where X is the resolution of the lens. I assume they made them and then graded them before marking them, but anyway, 7 is meant to be the highest resolution. They then had a little table of some of the different models that they'd tested with things like light transmission and resolution. The Helios 44-7 scored lower on the resolution test than the lower graded models. I found that quite amusing All this talk of vintage lenses is dangerous for me... I already bought a Pentax Super Takumar 55mm F1.8 M42 that I didn't need but was really curious about! Every time I look there are interesting lenses that tempt me ???
  15. Nice work. I really liked the atmosphere and colours, the Tiffen matched really nicely with the smoke too. The closing shot from inside the control room was a very nice touch too!
  16. I think it's getting more and more difficult these days to get clarity on what people deserve. You're right about the people that didn't vote, but for the people that did, the amount of misleading information around topics like this makes it pretty hard to understand what your choices really are, even if you actually care and put in time to understand the issues. The impact of the media constantly trying to trigger your emotions also doesn't help in keeping perspective.
  17. I remember the IS on my Canon 55-250mm zoom making a noise like a tiny turbine winding up every time you half-pressed the shutter. I don't know if the internal mics picked it up, but it was quite audible when using the camera, at least in some situations. It is surprising that the noise in your G80 remains when the IBIS is turned off though. If it's a software problem, perhaps resetting to factory defaults or updating the firmware might resolve the issue?

    I had a look through a few of the categories on the Pentax vintage lens site (linked in a previous post) and also did a search on eBay and nothing looked suitable. Vintage lenses seem to be common in 28/35/40/50/80/135mm and everything else is rarer, especially at the wide end.
  19. I believe it is more about religious fundamentalism rather than which religion. The Catholic Church resisted the heliocentric model of the solar system and famously kept Galileo under house arrest for the remainder of his life for supporting it, only formally acquitted by the church in 1992. Today, despite being perceived as one of the most western and scientific countries in the world, the US has a terrible acceptance of the theory of evolution, and the theory has very significant differences in the level of support based on religious preference (link). Islam has a long history of contributions to science and mathematics, and the word 'algebra' is even derived from the title of a book by an islamic mathematician (link, link). If people don't know their history then it's easy to attribute observations to the wrong factors, especially with a media that reaches for the latest and most controversial events it can find / invent. Level-headed analysis and fact-checking seem to be in short supply these days!
  20. I know.. think about how all the forums are full of angry people demanding 8K cameras! Once you understand that this progression is mainly driven by the tech companies constantly trying to find ways to make you keep buying things, then the rationale becomes clearer

    Probably the best approach is to get a FF or APCS lens and then adapt it to both systems. 7artisans 12mm f2.8 seems to be APSC and in EF mount Accura 12mm F8 The wide end is where lens choice becomes difficult on cropped sensors. I ended up solving the wide end of my GH5 setup with the SLR Magic 8mm and the Voigtlander 17.5mm because I can always use the ETC mode to make the 8mm into a ~24mm equivalent FOV, but these are both dedicated M43 lenses because I didn't want to be buying fisheye lenses.
  22. I have no problems with assessing people for entry into a country, especially if they are claiming refugee status. No-one wants to let criminals into their country, regardless of what motivates them to break the law. Unfortunately, at least here in Australia, these facilities are now being used as a deterrent to stop people from trying to seek asylum, where people are held indefinitely, refused basic medical care, and are never evaluated for entry into the country. We also distinguish people arriving by boat vs by plane. Boat people (whom Australians are terrified of) are taken to these offshore centres, but those who arrive by plane aren't. Our stance on boat people is so strong that we even got the US to take them from us... That's from the UN (link). It is the modern equivalent of putting heads on spikes at the border.
  23. Interesting. Maybe they just haven't sold enough of them to end up in the hands of people who don't value them and use them? They're a pretty niche item really, and they don't have the marketing of something like RED where every YouTuber secretly wants to vlog with one.
  24. I can understand how it's nice to think such things, but those numbers are way too low. Have a look at this: https://en.wikipedia.org/wiki/List_of_protests_in_the_United_States_by_size The largest item on the list is the 2017 Womens march with an estimated 3.3-4.6 million people. For context, that's most of the entire population of NZ. Was the march a success? Probably, but it didn't turn the political landscape upside-down or anything. In terms of how many people with guns it would take for the politicians to wake-up and take notice, who knows, but the first tactic would be to completely discredit and de-humanise them with a mass media campaign and then use overwhelming force. Each end of the political spectrum has managed to discredit and partially de-humanise those at the other extreme, despite being in the same country. Most western countries have de-humanised refugees enough to justify inhuman treatment and even offshore "processing facilities" where human rights seem to be mostly absent. Once the general populace thought they were anti-democratic anti-western extremists from the opposite side of the political spectrum to themselves, the government would treat them like any other armed group who explicitly refused to be controlled. Yes, there would be fallout, but not because having guns helped, there would be fallout because so many people died and a minority of people would be interested in why they did so, and the change would take place through the normal systems of democracy that are currently in place, not because the people with the guns ousted those in power.
