Most of the current cinema cameras and video camcorders are actually mirrorless cameras,they don't need OVF,they metering light on sensor. While Dslrs need a light metering sensor on top of the mirror to do so,and no matter how great their phase detection AF is ,it only works for stills Light metering sensorã€phase detection AF unitã€OVFã€mirror ，those parts of a dslr actuallly useless when shooting a video,but they take up 30-40% of a dslr's value, which meams 30-40% of your investments in dslr will be wasted if you are not using it for photography. And without those useless parts,they become mirrorless cameras , that is why GH4 and A7s make full use of their design,so they are better for videography not only because they provide great image quality but also there are not waste of videographers' money.

Please do not forget that 6 years ago,people did think that 5D mark II can't compete with DV cams ,because of its lack of many video-needed features (like what you mentioned as c300's advantages) But nowaday 5D series are being used in filming many different videography works,including cinema projects. The most important point is Image quality, always come the first to one's mind Canon know that well ,and that is why they only provide advance sampling for the C series ,while none of their DSLR or Mirrorless cameras get better sampling except line-skipping On the other hand, Sony and Panasonic do provide super advance sampling for their cheap DCs, like the RX10 GM1 G6 I think that Canon have to update their C series first,then comes a dslr using better sampling <_<

now I see ,there are many canon lens owners like you,hoping that canon can do something,but those line-skipping Dslrs really wasting all your good quality lens ,moreover if you think about no power-zoom , quite-AF motor and smooth focusing ring ,ect There are endless demands, dude

DSLRs are already out of date for videography,and canon cameras always have overheat issues which make 4K video and high framerate became impossible，check out the C500，then you will understand Do you actually think that canon will deliver a dslr under the price of 3000$ that can do 4K video which the cinema cam C300 doesn't provide? Come on ~The manufacturers are not playing their game in this way.

Its poor compression codec make huge unnecessary filesize, moreover it is lack of many necessary features for pro works ,and it has strong rolling shutter effects,therefore I think The 1DC is not just overpriced,it is too outdated,even its color science doesn't worth that price level

A lot of GH4 fans are gonna disappointed or oppose this test~ For A7S ,it looks like awarded the gold medal,but for many other cameras , it is a death knell!

canon has join the competition by reducing the price of their products,maybe it is the only strategy so far

Oh come on ! I thought you drawed your conclusion by some tests or videos review! How can you judge something that you did't even test it ?! There are some points you mentioned that I disagree with you : The picture profiles on A7S is way more advance,you can change internal color performance of the camera.Simulate the canon-like colour is also possible,while GH4 can't do as much as A7S can. So I don't think the Color science and skin tones are advantages on the GH4. Actually the color performances on the A7S is not bad! Moreover, A7S has much better dynamic range,people hardly see the differences between F55 and A7S in terms of DR! (see this video :

SONY a7s s-log2 test HD 1080p： I don't think that it is necessary to compare the cinelike profile with S-log2 now,S-LOG2 is really a tool for work! While cinelike profiles are NOT !

This is a comment from alex (a C300 and GH4 user),comment from www.fstopacademy.com,7S hand on shooting review: Alex said: For anyone who’s concerned about grading the 8bit of this camera vs 10bit of the GH4… I think it’s going to be a non-issue! Testing yesterday, with the GH4 recording 10bit to a Ninja Blade, I found I could push the 8 bit internally recorded image from my C300 (50 Mbit) WAAAAAY further before either fell apart! Specifically I was trying to see if I could underexpose to protect highlights in high contrast documentary interview situations. With the C300 I could push the midtones up by 25% (probably even more with a de-noiser) before I would start to feel uncomfortable about using them. The GH4, however… I couldn’t move push the midtones more than about 5% before it looked too ugly. I fiddled with the NR settings, shadows, highlights, contrast, Cine D Profile, Natural Profile, but nothing made me smile and go… “Yeah! I like that.†As he said, GH4 with IPB code perform badly in color,and I don't know whether the 10 bit will help,but it may not be worthy because it requires a external recorder to do so. In a A7S review from Newsshooter.com,W. Ashley Maddox said: it(A7S) had a natural grain look to it vs. the muddy blacks that I am seeing in the GH4. Compared to the FS700’s AVCHD, the XAVC codec is way easier to grade. so,both camera in the same 8 bit color but xavc does performs better than the IPB(the same code as AVCHD ) code on the GH4! What a shame that GH4 is not using a better code instead of IPB!

Unlike common gamma Log Files ,Cine-D file does not require a native ISO,and there is no official technical info explain how it work to reserve more DR,so thinking of it as a gamma profile is much like a joke <_<

Hey,Andrew.I have heared that the picture profile (especially the colour settings)on A7S can achieve any type of colour . Simulate the canon-like colour is also possible,not any other camera in the same price range peovide that . Sony officially provided a recommended PP file for FS100 to match with the colour of 5D2 ,but do not know if it works the same on A7S ,its content is listed below: Black level:- 15 Gamma: ITU - 709 Black gamma: range low, level + 4 Knee:manual point 75% Slope 0 color mode : ITU - 709 matrix ,level + 1 Color level: + 3 Color phas:-4 Color depth: R – 3 G – 7 B – 4 C – 6 M – 7 Y – 5 Details: + 7 when you get a A7S ,you can try it if you like . :P So,is canon still have their advantage in colour science?I doubt that~ um,then we talk about canon lens .As I know that Dual- pixels autofocus only work silently on STM lens.any other type of EF lens will make annoying noise ,which make you won't be able to record sound at the scene. That means all your non-STM type lens(Especially high-quality L lens) will be wasted for future investment, that quite disappont a lot of canon users who need AF very much. and forcing them to buy new STM lens ,moreover,you cann't expect canon to fix that problem by changing all len- motors to STM so ,yeah I know Canon make good lens ,but for future investments,not a good choice.

You do know it will cause a painful loss when you swicth from one brand to another,right?

Hey Guys ,Check this out! http://www.dxomark.com/Cameras/Ratings/Landscape Turn the filters on to compare canon cams with sony cams You can see Canon is already way behind! The 1DX(the same sensor as 1DC) only get 11.8 stops of Dynamic Range.It is differ from the 400d(which was released in 2006!) only by 0.8 stops! what canon did greatly improve in the recent 8 years ?I think mostly the Software and phase detective auto focus??! While Sony did improved GREATLY from 2006 to 2014. In 2006 ,first sony dslr A100(11.2EV)released, then today we see the a7(14.2EV) acheved a much higher score. All this bring to a much strange question:WHY sony frustrated in DSLR businesses(only got 15% market share) but still trying to be the BEST. While dslr king canon develop their image technology SLOWLY as a snail (obviously canon is not lack of money to do a better job) IF this keep going on ,canon is NOT going to bring you a promising future! Remember there is always a rule of surviving:not to advance is to go back! ^_^ If canon really want to respond to competitors,them should try very very hard ,and act fast ASAP ,before it is too LATE!(ummm, it is a little bit late actually~) :(

Recently,the launch of Olympus E-M5 has excited me! I think this camera will be  the new Four Thirds flagship.It has a superb build-in stabilizer,which may kill all steadycam systems.and its waterproof and dustproof body is great for more camera shooting positions(like under water) And  the tiny GH2 won't be able to do this ,maybe even the GH3 in near future. If the  E-M5 has much the same video quality as GH2,it definitely will be one of the best video cameras! ;D Here are some links to video samples of E-m5,check them out!

My question is the title~     For my opinion，the  3×3 binning is much like a digital low pass Filter .By binning pixel ，it cloud reduce Moire，but like the low pass Filter ，it will cause resolution loss in return.     When I saw the ISO test video shooted  by 5DM3,it showed resolution loss ,but I ddi't think it's caused by NR or out of focus.After all,the video was came from Canon Japan,which mean it is highly credible.     What's more ,as it's cuased by binning pixel,the high bit rate mode like ALL-I won't be able to make up the lost resolution,and sad to find out this function can't be disable if user wanted.     I am not a expert in this aspect,so I can't sure my opinion is absolutely correct.     Let's discuss and find the answer . :)
