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.

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!

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.

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.

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.

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.

You're assuming that he sound quality gained would be more valuable than the compromises it would require, like size, ease of use, weight, attention from others, etc. On commercial sets these things aren't normally considerations, but are for others. @bluefonia said "These days I make films for my own pleasure - no dialogues, cleansounds only - and want to keep equipment at a minimum" so adding a boom doesn't seem to be sensible. I investigated buying a stereo mic, or making some kind of mid-side setup, but in testing the internal mics in my cameras I found them to be fine for stereo recording, so I just use a Rode shotgun mic and if I want ambience I record using the internal mics on the camera. If you buy a Rode Video Micro (or cheap equivalent) then you'll be reduced to mono sound. I have thought previously that you could combine a stereo splitter adapter and plug in two of these mics and angle them in an X-Y configuration to get a stereo signal, like this:

There seems to be a very strange understanding of military tactics and weaponry going on here. The scenario that some people seem to be suggesting is that this happens: the people learn that their government can't be trusted for some reason and decide to replace them using force they then stage some kind of guerrilla war against the government forces they win this war because they have a very large number of very low powered weapons If this scenario is really a battle for the entire country, and neither side would hold back. So it wouldn't matter how many AR-15s or even M60s you have, when the army deploys APCs, tanks, and armour-plated surface-to-surface missiles on the ground, deploys drones, helicopter gunships, and fighter planes with air-to-ground laser-guided missiles, and the navy parks a battleship in the middle of every major port city and aircraft carriers out to sea far enough to get clear airspace, the armed population will discover that even if they had 800 trillion zillion quadrillion guns that can't shoot through armour they still wouldn't be much help. Remember that when the entire population is behind a movement then it wins against the government without needing weapons. It's only when it's not a majority of the people that weapons might play a part in something. Therefore it would be more like: some people learn that their government can't be trusted for some reason and decide to replace them using force, and they then stage some kind of guerrilla war against the government forces government forces would fall back to secure facilities and would establish supply lines between facilities and intelligence services would be monitoring communications working out who the leaders were and how things are being organised, potentially shutting down key ISPs etc using superior armour, tactics, military intelligence, and weapons, the government would gradually re-take pockets of resistance The scenario being described isn't like two armies fighting, it's like a team of navy seals in full body-armour with night-vision attacking a tribe of jungle warriors armed with spears. Of course, if it was a large enough group then the government would realise that there's votes in it and so the political landscape would change radically. People don't like to see video of soldiers shooting at their own people, although the US has gotten pretty used to government forces using unnecessary force on its own citizens, the fact nothing has happened in response to that might be a clue about how power really works. So, it would change things significantly, but the fact that the people had guns doesn't tip the balance in any significant way.

Cabin bag weight is a worry for me as I never want to be forced to check any equipment. I've done a lot of reading on the subject and there are a few general approaches, but the one I like is that if it becomes a problem then move away from the people weighing the bags and then put the heavy items in your pockets to get the bag under the weight limit. They don't weigh people and so this is a good strategy if they don't know you've done it. Photographers often talk about having a photographer / hunting vest that has lots of huge pockets in their bag just in case and this is what I've done. I suspect that if you're an asshole and start filling your pockets right in front of them then you may not get away with it, so that's why I suggest moving away from them.

I buy whatever is cheapest and just make sure it's fully backed up. Also, keep your backup drive disconnected from your computer in case you get one of those viruses that lock up your data. You should also keep your backup in a different location to keep it safe from fire or theft. In having said that though, what was cheapest tends to remain cheapest and so as I've needed more space I've bought similar drives in anticipation of creating a RAID at some point in the future.

Interesting video, not only for that section but also for more useful tips, like the creative team getting to know the style of the film through the DP shooting his own feet walking through a field, and using doubles for follow-shots, even before the main actors are on-set. This might be of interest to you @mercer for improvisational short films?

If you want to avoid recording the noise then maybe the solution is an external microphone. A previous conversation about how to use an external mic while keeping the setup very compact yielded these insights... Using a Rode Video Micro you can either mount it above the camera in the traditional way like this: Or on a flash bracket by the side of the camera: or @Don Kotlos took it one step further and used velcro to attach it to the body of the camera itself:

I don't know those lenses, but I'd suggest searching YouTube and Vimeo for example video footage and reviews - there are many people who are buying vintage lenses these days so there's lots of information around. Also, google will turn up lots of good information, and remember that photographers often post images from these old lenses and so these photos give a way to see how sharp the resolution of the lens is (4K video is a series of highly highly compressed 8MP images, but 24MP high quality still images are common). I've recently found sites like https://www.pentaxforums.com/userreviews/ very useful as they aggregate reviews, give ratings, and also give price history.

The GH5 is good but not great in low-light, therefore you want to use the fastest lenses you can get. This will also mean that your depth of field will be relatively shallow - unfortunately there is no way around this with this camera. Your 12-60 f2.8 isn't a very fast lens. I would suggest either getting fast MFT lenses like the Voigtlander F0.95 series primes, or getting a speed booster and using something like the 18-35 f1.8. These will require manually focusing. I recently filmed a lot with my GH5 at night using only the ambient available lights and I found that I really needed to use my Voitlander 17.5mm f0.95 with the aperture fully open at 0.95. The alternative is to rent another camera setup that will have better low-light performance. Perhaps something like the A7SII or A7III with a 24-70 F2.8 lens. This setup would enable you to get noise-free shots with a deeper depth of field than the GH5/fast-lens combination.

I think I've worked out how we stay relatively sane and civil on these forums when talking about cameras.... We let it all out in threads like this! I mean, seriously, read this thread from the beginning in one go! ???

I'm confused. If the people need 100 million guns then who are they going to be fighting against? If it's anyone other than the US government then they'd either need a navy or snowshoes, and if it's someone to the south then they'll be completely screwed because there will be a great, impenetrable, beautiful wall in the way ???

I have this kind of setup to connect my 4K Dell to my MBP via a cable. In terms of testing it beforehand, I'm not sure how you would do that, but I also think that maybe you don't need to. If you get the RAID setup and it doesn't work with the ASRock Thunderbolt 3 at 40Gb/s then just return the ASRock and get something else that does work. Even if you have to bin it and buy another Thunderbolt card, you'd still lose less than buying your second RAID choice.

Every time I see a screenshot I always look at how much battery people have left. It's probably because my wife and kids are always screaming about having 2% left when we've only left the house 5 minutes ago, and I just wonder why they don't charge them while they're at home... 26% - that's considerably above average from what I see online, well done! My impression is that they're kind of the "zero ergonomics modular camera" equivalent of early Blackmagic. They push what can be done for the money, but the question is if they're reliable. Most of the reviews I've seen online from previous models are from people who pre-ordered really early and are receiving the camera in the first batches. The reviews typically include a mixture of gorgeous footage from the Kinefinity, nice footage of them using the Kinefinity, and shaky iPhone footage from when the camera totally bricked itself and won't turn on again, followed by a narration about how it took an hour on the phone to tech support to reset it, or how they had to send the unit back and that's why the review took 6 weeks to film. I think they've got a lot in common with the P4K in that naive people likely ordered based on specs and end up selling it when they realise the camera isn't waterproof (or something equally obvious to most people) so there might be some bargains around second-hand. However, I'd read a lot around how buggy the firmware is before parting with your money

Is this to do with the mechanisms that combine the pixels together to down-res the output to 4K from the 8K sensor?

Did they cover fully-normalised databases yet? If someone says they've studied database design (in a programming context) and they don't know when a fully-normalised database is better than a semi-normalised database, then I just assume they're lying and/or don't know anything I think it's down to the clothing. @Kisaha also said "which for my country equals to Polar temperatures" which is true for me as well because we don't have clothing that is suitable for that kind of thing because it basically never happens! The wife and I are contemplating visiting Antarctica at some point, and apart from renting some really nice lenses I think I'd also rent some suitable clothing too

In a battle between the people with 100 million guns and the government, my money is on the side with the predator drones, not with the side who can't even talk about photography equipment online without getting into an argument.

Based on the Z Cam E2 already having done it, I'm also pretty certain it can be done.. ? That's not the limit in terms of what is state of the art either... both the RED MONSTRO 8K VV and the RED HELIUM 8K S35 do 8K60, and in theory they should be able to pump enough pixels for 4K240, so either they didn't think anyone wanted it, or there's some other limitation.

No worries mate... -3 would make me pretty grumpy too! All professions, huh? ALL professions? Really? Lawyers? Lobbyists? Hitmen? ..................Politicians? ???

What setup are you thinking of investing in?
