I think that is just for stills. I dont even think they have DMF in video mode. @jonpais 1. Well you could put focus magnify on a custom function button. 2. I am willing to bet (never used the Sony FE 85 1.8) that you will get better stabilization with the Batis 85 (my favorite video lens) because of the built in OIS - it still wont be up to Panasonic though.

Purely speculating. But I think it is very likely that Canon will put FF in its existing EF-M for APSC. The throat diameter of EF-M is 47mm which is wider than Sony E mount. This would also give an (ongoing) upgrade path from APSC to FF for mirrorless buyers.

I dont agree with the first point at all - in fact I havent bothered reading his 'jokes' because whether they are funny or not I think is irrelevant. And I definitely dont think you should sack a film director because his jokes arent funny. The second point is far more salient. What it comes down to is this. There are many things we say to our friends - call it pub talk - which can be enjoyed between us because we are friends and we know each other. But it is ill-advised/stupid/problematic to transfer your 'pub talk' to the internet because it is both bound to be taken out of context and likely to cause offense. Afterall, there are some things that you say to your mates that you dont say to your grandmother. And if your response to that is 'not really, you dont know my grandmother' - I would say 'exactly'.

I think this a good point. Brits have a very dry sense of humor and they also consider that 'jokes about pedos sort of makes you a pedo' a very strange and false equivalence. But it is dangerous territory. I have just been watching Sacha Baron Cohen's 'who is America?' and I laughed so much it bought tears to my eyes. Others, however, think he should be thrown out of the US and are threatening to cancel their Showtime subscription. So I also feel that Disney is perfectly entitled to sack Gunn if he is damaging their brand. Take Ricky Gervais - who used to insult the audience at the Emmies - even he would say 'well if they find it offensive, they wont invite me back, will they?'

Are you doing something like this?

I have always thought that Twitter was a very bad idea. I mean taking the first thought that comes into your head, immortalizing it on the internet where it can be taken out of context by random strangers, is virtually guaranteed to end badly at some point or another.....

Forgetting the rant at the end there (which may make a lot of sense) but is a totally different subject. I fundamentally disagree (in most cases) with the point I have highlighted in bold. Generally speaking, video editors 'want' as much power as possible to 'render' video. And 'as much power as possible' (as well as quite a lot of disk space) is the complete antithesis of 'small light and portable'' in every sense - battery life, sound, efficient use of cpu/gpu etc.... So what you end up with imho is a massive compromise on both usually at a very large expense. Your laptop isnt very powerful or if it is, it isnt very portable. You can add an egpu, docking station, decent display and laptop fan but all you really end up with is a feeble desktop with no portability. So if you look at all the add-ons for a Macbook Pro, they really appear to me to be trying to recreate a 'desktop replacement' in a 'minute form factor' and that is almost certainly a concept for an extremely 'expensive' solution to the underlying problem. It might be the right one for some people but I doubt it is for most. I would guess for most people who split there time from needing 'portability' and 'power' - actually two computers makes a lot of sense.

I'm not sure I agree. By the time you have bought your fan, external egpu and desktop monitor to recreate a fairly feeble desktop, you should realize that what you probably need is an iMac (pro). And if you need to save money and want to remain portable just get a fairly basic Macbook Pro 13. I used to use M43 which has a relatively small sensor. I found I was spending more and more on heavier, faster lenses that eventually I realized what I actually wanted was a bigger sensor.

A pretty strong comeback to the i9gate issue...

It certainly seems a popular product with youtube vloggers.....

I agree with you about the lens mount (but at least they put the lens release button on the right side.) Not so much about the grip being too short. Yes, I hear where you are coming from - you are used to a DSLR where your 'pinkie' fits on the grip and that feels comfortable - so it doesnt feel comfortable when it doesnt. However, I have a different experience. I have never owned a DSLR - only mirrorless - so I am used to having my pinkie under the camera. If I pick up a DSLR or even use the battery grip, it feels uncomfortable/klunky to me. But I would guess that Nikon will design their mirrorless to suit DSLR/ex-DSLR users and go with a longer grip. In fact, I suspect they will go pretty retro and their mirrorless will look something like a FF Fuji....

Ok so here is what I dont get about this.... (BTW I understand that 2000/MBs disks are great for operating system start ups.) So, say my Sony records at 100Mb/s which is 12MB/s and my Mavic Pro records at 60Mb/s which is 8 MB/s. I can download RED 4k Raw which will be 20MB/s and 160Mb/s. So what essentially use is a 2000/MBs hard disk in terms of read or write speeds for video? And I know I sound a bit of a whinger. But essentially I am in the 'dont mind spending money camp' as long as I get 'decent performance gains'. And I just feel there is a bunch of smokes and mirrors trying to sell us i9s in wafer thin laptops, egpus because we have wafer thin laptops, thermal throttling, thunderbolt 3, Titan Vs, fast ram etc without a whole of evidence it does a lot of good - and if it does what? And really I dont think everything should be setup in a way that you need a degree in particle physics to work out what you should buy.

Looks like the i9 is to be avoided....

....Or you could at least look it up....

Well here are a few numbers..... What does it cost to manufacture a camera? So here are Olympus's financials (admittedly for the whole company) Note that their gross margin is 'massively' high at 65%. Historically they used to breakout the gross margin for their cameras which was around 50%. To put that in perspective Apple's (a company that gets away with charging a lot for stuff) chugs along at around 38%. So manufacturing cameras - especially mirrorless which is just a bunch of chips on a motherboard - doesnt cost a lot (Nikon and Canon's gross margins are lower.) However, SG&A expenses are also incredibly high - these are largely fixed costs and so if you dont sell much they end up as high (Nikon and Canon's are a lot lower as a percentage.) When it comes to R&D, Olympus reports for 'imaging'.... 4bn yen (US$40m) which is around 6% of revenues (and Japanese Cos overstate R&D for taxation purposes.) And even US$40m isnt a lot... So if you take the Panasonic GH5s, I dont think there is a whole lot of cost or R&D. The sensor is made by Sony (and by most accounts) is an off the shelf security camera (Starvis) sensor. The shutter will be made by Nidec Copal, the EVF most probably by Epson etc... etc...

Actually I dont think this is true. I just downloaded some 4k REDcode RAW applied a bunch of color grading in Premiere and rendered it out. (As an aside, wow it is great fun to color grade with raw footage.) But the footage with edits played back flawlessly in Premiere. It also rendered out in real time - essentially 20 seconds in 20 seconds. That is at least 5 times faster than my Mavic Pro 4k footage. The problem a lot of us face is that we are dealing with heavily compressed codecs which massively slows down our video editing...

So a decidedly mixed bag in terms of performance. Not particularly surprising as an egpu provides a mixed bag of results on the Windows side too. Of course we are bound to see a lot of evidence about how Blackmagic's egpu improves performance in Resolve in a 13 inch Mac Book Pro which doesnt have a dedicated GPU. But as Resolve actually needs a GPU to meet its system requirement all you are really seeing is how badly Resolve works without a dedicated GPU.

It will be interesting to see his test results. One thing to note. Davinci Resolve is the only NLE (that I know of) that includes having a GPU (with 4GB memory) in their system requirement. Premiere and FCPX say a GPU is optional. My assumption would be that if you write a program that doesnt require a GPU, it is unlikely to be optimized for use with a GPU.

Broadly what I am saying is this. CPUs and GPUs do fundamentally different things. GPUs have a lot of cores operating in parallel and are good at essentially solving a single equation very fast - so graphics in games and bitcoin mining. CPUs are designed to resolve multiple equations at the same time, such as running an operating system. In general, NLEs are likely to be CPU constrained (by that I mean if your CPU is running at 100% and your GPU is running at 80%, putting in a 4x more powerful GPU will not help performance as it will simply run at 20%.) So to the extent that all NLE's are generally CPU constrained, I think that Resolve probably makes best use out of the GPU. In other words a higher end GPU might have a greater impact in Resolve rather than FCPx. You can go here if you want a lot of detailed analysis of this https://www.pugetsystems.com/ But the simple point is that NLEs are largely CPU constrained so 'more powerful' GPUs dont add much performance beyond a certain point.

And I am arguing that you are looking at the problem back to front. The 'reason' Apple computers dont use 'better GPUs' is because NLEs are not capable of taking advantage of them. They make efficient use of what they have got but if they had more, they wouldnt. (Case in point if I moved from a US$700 1080 to a US$3500 Titan V 12gb gpu, for Premiere on a PC there would be virtually no performance advantage.)

You maybe looking at the problem backwards. Apple computers may make fairly efficient use of GPUs with FCPX but, in general, they dont have very powerful GPUs to start with. So a US$4000 iMac has a US$250 Radeon 580 GPU. Probably the same reason that the Blackmagic eGPU doesnt include a more powerful GPU.

You need to bare in mind that I am more a photographer and have only attempted video in the last year. To me this video shows a lot of the A7riii (which is almost identical to the A7iii) features..... 1) Handheld video at 85mm 1.8 is a breeze 2) Video af is pretty good (note it wasnt distracted by the bright light.) 3) I dont know what the iso was but it was decently high (say 3200) and the video looks very clean to me 4) The internal mics sound pretty good to me (apologies to sound experts.) 5) Straight out of camera colors look decent to me 6) You, of course, have the full frame look...

I doubt the industry is going to go in the direction of multiple external GPUs for either gaming or video editing. I find my 8 core 145 watt cpu is the constraint on my pc rather than the Nvidia 1080 so I seriously doubt we will get to the stage that mobile CPUs are not constrained with multiple gpus. (I am admittedly using Premiere with a compressed codec.) BUT if you go here..... https://www.pugetsystems.com/ ...you will find a lot of testing and a lot of hardware recommendations. In general, they dont recommend multiple gpus (these days) even with desktop cpus. In general software developers dont have any real incentive to produce software optimized for multiple gpus because they are a very small demographic....

Yep, this is a sort of pet hate of mine. Edelkrone, for instance, only offer product manuals in video form not in text. And I can pretty much bet when I have a problem it is always somewhere with very limited internet.
