Guest Ebrahim Saadawi Posted June 17, 2015 Share Posted June 17, 2015 1- They solved it with making the body significantly larger, with better heat management from the sensor and the sensor components them selves do not generate as much heat as the earlier ones due to the changed materials. 2- Maximum record time is 29:59 minutes. 3- The internal 4K (only UHD-3840x2160) is XAVC-S, H.264, 8bit, 4:2:0, with a 100 mega bits per second bit rate. The HDMI output is the same not 10bit. There are two options to record UHD one is using the FF sensor, with the penality of having aliasing/moire and worse rolling shutter, and a s35 1.5x crop that's absolutely clean. 4- Not sure but I do think it does have wifi capability. Double check on that one. Quote Link to comment Share on other sites More sharing options...
Guest Ebrahim Saadawi Posted June 18, 2015 Share Posted June 18, 2015 All 4K footage keys extremely well, better than 1080p 10bit 4:2:2. I wouldn't worry about keying with the A7r mkII,I'd worry more about banding and codec artefacts that will appear when pushing the exposure up as with all 8bit 4:2:0 100mbps cameras.

maxotics Posted June 18, 2015 Share Posted June 18, 2015 Are you referring to STILL or MOVIE Images in your declaration? Hybrids are expected to COMPROMISE to achieve a balance.I'm with you. I'm just pointing out that for professional MOVIE filming only, which the C100 is aimed at, the "better" hybrid specifications are misleading. zephyrnoid 1 Quote Link to comment Share on other sites More sharing options...
Gregormannschaft Posted June 18, 2015 Share Posted June 18, 2015 All this sounds great but I'll wait to hear of news from the A7S II. That and..I'm still pretty happy with what the original A7s gives me. Time to stock up on good lighting, a rig and start making some amazing films. zephyrnoid 1 Quote Link to comment Share on other sites More sharing options...
Oliver Daniel Posted June 18, 2015 Share Posted June 18, 2015 There is no denying that this looks like an impressive camera, but I'm going nowhere near the pre-order button until I've actually tried it on a professional shoot. I do that with all new cameras, throw them into the deep end straight away and start shooting a paid project. The 4k, 5-axis, Slog2 etc means nothing until it's been put through it's paces.

William Koehler Posted June 18, 2015 Share Posted June 18, 2015 yes! My hope for a7s2 is 24mp allowing for 4k apsc mode.Actually, Sony only need bump the A7S2 up to 18MP to allow for a true 4K APSC mode.If they bump all the way up to 24MP, the question quickly arises: Why does the A7 exist? The A7R2 and the A7S2 would cover all bases and the normal A7 gets squeezed out. Quote Link to comment Share on other sites More sharing options...
IronFilm Posted June 19, 2015 Share Posted June 19, 2015 This reminds me of when everybody was falling over themselves for the Sony A7r when it came out!But then along came the A7s.... I'll just wait :-DHistory will repeat itself. Jimbo 1 Quote Link to comment Share on other sites More sharing options...
amanieux Posted June 19, 2015 Share Posted June 19, 2015 why the hell do they put a 30 minutes limit on video recording on their high end 3k$ prosumer camera ? (the gh4 is half the price and has no time limit, are the gh4 and the 2 blackmagic 4k the only three sub $3000 interchangeable lens camera to be free of this 30 min limit in 4k?)

This is nothing to do with technical limits.

Heat builds up!!!you are right there is a heat issue but i notice that a tiny gopro4 enclosed in a waterproof plastic shell that is not good at dissipating heat can still record 4k for hours. even if a full frame sensor dissipates more heat than a gopro size sensor, there are obviously ways to dissipate heat in such a bigger camera body, they already have fans on pricier camera, a fan costs tens of cents.

It's about taxes: http://***URL removed***/articles/0794343949/wto-looking-at-moves-to-remove-30-minute-limit-from-digital-camerasi know there is a tax in europe but it is a 5% tax, any customer in europe would be happy to pay 5% more and have no time limit, the camera makers know that but i think they are just protecting their high end pricy market cameras at world level by applying the linit to the world. when there are no longer technical arguments to differentiate these markets they need to add artificial restrictions, like lower bitrate, time limits, remove a 50cts headphone jack etc ... the problem is that hardware R&D is driven by mass market components so progress will come from low end hardware, they will have more and more problem defending their high end market because there will no more be high end sensors . this already happend in cpu and in 3d graphic cards because there is 100x more R&D investment on these chips. camera sensor makers invest much more r&d on smartphone camera sized sensors and not on full frame sensors because they sell 10000x more smartphone sensors than full frame sensors. the other incentive to use smaller sensor is the rejection yield is so much greater on bigger sensors, i bet we will see in the next 5 years see bigger sensors replaced by multiple smaller sensors recreating better images at a lower cost with computational photography (http://linximaging.com/).

Super Members Mattias Burling Posted June 19, 2015 Super Members Share Posted June 19, 2015 i know there is a tax in europe but i was speaking of the US market.My guess,It costs more to manufacture two models with two names, separate boxes, firmware, manuals and so on when they can just make one.It will of course upset a few enthusiasts like us here and there but the absolute majority of camera buyers couldn't care less.

Julian Posted June 19, 2015 Share Posted June 19, 2015 i know there is a tax in europe but it is a 5% tax, any customer in europe would be happy to pay 5% more and have no time limit.I don't. I prefer paying 5% less and having the 30 minute recording limit I'll never reach anyway.Of course I understand there are plenty of people who'd pay the extra for not having the limit, but I don't think I'm the only one who doesn't have a problem with 30 minutes max. sudopera and Marco Tecno 2 Quote Link to comment Share on other sites More sharing options...

fuzzynormal Posted June 19, 2015 Share Posted June 19, 2015 It's funny how some say "Europe", "Africa" or "America" like it was just a countryWe can't think about everything. Americans got enough on our plate (that's literal, not metaphorical). For instance, our Olympians are changing their gender 40 years after they were in the spotlight, so you shouldn't expect us to concentrate on lesser issues.
