The magic word you are looking for is PDAF - a7SII only has CDAF

This is one advantage that I feel Avid has. Proxy mode is just a selection in a drop down menu. No extra media created, works instantly. When you're ready to export, just turn off proxy mode and export.
If a computer would be powerful enough to transcode you source media to a lower quality proxy on the fly, then you wouldn't need proxies at all. And since proxies are used when a computer is not powerful enough, there must be some files stored somewhere where you can't see them (don't fool yourself). Kdenlive for Linux uses a dedicated proxy folder and names the files by the md5sum or some hash value.
-
Then the issue is again much non-existent - do transcoding every night and you'll come home from the road ready to edit (or be ready to edit footage from the previous day).
And yes, if you can afford to shoot 1 TB per day (costly highend camera, costly portable storage etc.) you must be better off economically and should also be able to afford a respectable editing machine.

RIght, I guess that's my problem... I usually come home with 1TB and the transcoding takes over a full day of time. I guess I need a transcoding machine. My complaint is that I don't need to do any of that in Edius. I go straight to editing.
Well, if you can afford the equipment to shoot 1TB per day, then you can afford a proper editing computer. But in case you have a cheap m43 4K body, a powerful editing machine is not a given and proxies work great.
-
Been using proxies to edit 1080p files for a long time, and it really is nice. If you shoot the whole day, you can transcode them over night and you loose no time. And if disc space is a problem, create smaller proxies.

Cinema5D continues with the moaning rhetoric, yet disqualifies all PRO complainers with the official Sony statistic:
Working professionals are 16% of all buyers for the a6300 - sales are after volume and PROs are still a minority. The statistics for a6000 would probably show an even smaller percentage of PRO users.

Sony really needs to come up with a substantial touchscreen FW update - it works nice on a5100 and previous models, so they have no reason not to make it work as it should.

Nice work Dave. Whats interesting is Canon already has designed the perfect 1DC mkii sensor, the 12mp full frame from the orginal 5D. I'd love that in a 1DCII, full frame 4k with everything else you mentioned.
There is more to sensor design than just mpx count. Readout speed and noise get improved by hardware changes and not exclusively by better processing.

its slightly bonkers that a drone manufacturer is pushing the camera tech envelope more than the camera manufacturers. You need certification to fly the inspire in australia, so it's off my radar for now, but if I had it it would be a no-brainer. Next phantom could well have raw vid. Helloooo... Nikon.... wakey wakey.....
Actually, we have established why DJI can do 4K60p - by using fans and having a lot more space to work with in regards to heat dissipation. Smaller mirrorless bodies simply cannot process that much data and not overheat fast. Much the same as smartphone sensors being able to capture 4K60p for some time now, but it would fucking fry the phone with the current processing power.
-
So, is the far better heat dissipation the main reason DJI can do 4K60p? Would the cam itself overheat if used for longer than the flight time (on an Osmo)? Or is their processing so advanced (aka Samsung like) that Sony and company cannot keep up?

The main problem with smartphones is their lenses. While Pixel lens is way better than other flagships but its still far behind even a P&S camera lens. and they can't do much to improve it though, I mean its ridiculously tiny plastic!
Of course they can ... no one is forcing the entire industry to make such slim phones. Give us some semblance of a grip, thick body with larger battery and maybe even a 1" sensor like Panasonic CM1. Or Samsung could finally produce a 4K K Zoom successor. Zero innovation in hardware, just waiting for the latest Sony sensor and that's it.
-
just a quick question: would you guys consider a RX smartphone, which would be as thick as a RX100, but only feature a prime lens? I love this idea, but the Panasonic CM1 didn't really get a lot of attention
-
what about a cheap used netbook that can hold an 2.5" HDD?
-
Isn't it 24fps RAW too?
-
Now if only Samsung hadn't left the game and made a NX2 mashup of NX1 and Galaxy NX and made the camera body run Android. Youtube-level real time EIS is a reality with Pixels and having it on a high quality body would be so nice.

Here are some details on the sensor found in the Pixel. The sensor is capable of much more than what Google implemented in the Pixel.
So we have a pretty good chance of seeing a Snapdragon 830, 4K60p, HDR video, OIS flagship in 2017 and should hold out on buying the Pixels.

If you are OK with a bigger body, you might as well buy a cage with a fan built in. The compact body is perfect for the average consumer, who takes clips of 5-10 mins and primarily takes photos.
Mirrorless cams need to keep the small form factor - that it their primary appeal (for the general public). Filmmakers would never choose them if some Canon would implement an EVF with peaking, zebras, log, swivel-screen, no crop 4K, dualpixel AF etc. into their 5D body. But Sony and Panasonic filled their cams with video features and filmmakers took note.
-
Ok, so to address the sensor possibilities for the mark III version. I highly doubt that 4K60p is possible in such a small body even with LSI, so the next big thing might be increasing the FF sensor to something like 20mpx and doing a 5K full readout (like RX100V) and downscaling it to 4K, giving superior detail reproduction. 20mpx also gives you approximately 8mpx in APS-C crop and a 4K capable crop mode.
Built in ND filter seems like a stretch: the FF sensor already occupies the extreme edges of the mount and how would you physically cram a file in there? The did it on a super-35 sensor so far, but the size difference is huge.

Apparently, the smartphone's camera will be based on a new Sony-made IMX398 sensor ... the source states that the sensor is a 16MP dual-pixel affair (similar to the 12MP Samsung Galaxy S7 camera).
Maybe we can expect a new dual pixel sensor and the A6700 in about 8 months, don't buy into this A6500 mumbo jumbo (I know IMX398 is a tiny sensor, but the tech is now available to Sony).
-
Let's suppose everyone here is advanced enough to understand the pros and cons of different sensor sizes and the limitation of speedboosters and not derail the topic. This happens all the time. Some get agitated because m43 isn't getting enough love - it gets its fair share.
-
A6x00 all look the same, but they all have a different internal design. Dpreview talks about this in every hands-on article. A6500 is 5mm deeper, due to IBIS. A6300 was completely redesigned to feel more premium and for better sealing (still no guarantees about it though).

Quote"In an interesting update, there's a new menu option which changes when the over-heating warning icon appears: there's Standard or High options, the latter simply allowing the camera to keep operating even when it's getting hot, although protection will still kick-in to prevent any damage. When shooting with the earlier A6300, I found the body could get quite hot to touch, and revealingly Sony's engineers recommended using the A6500 on a tripod when the temperature warning had been adjusted - not to do with stabilisation, but because the body may become uncomfortably hot"

Sony A6500 movie and photo samples are coming in

Can you guys imagine there is a whole other group of users that thinks the AF is excellent and is looking forward to that insane buffer? A6500 is expensive, but most of its features can still be had with the A6300. R&D costs and APS-C IBIS was developed for this body only (not like FF IBIS that is used in 3 bodies) and that same IBIS should be coming to the FS series, as well as AF and super slow-motion using that LSI buffer. I'm guessing that super slow-mo bursts could be coming to the A6900 too and it will be expensive, but there will be nothing like it on the market, again.
