Talking about rock solid performance please do not forget that GH2 had a dreadful battery life and GH3's viewfinder and screen was practically unusable for many. GH4 has come a long way and it really looks like the first DSLR(mirrorless) truly made for video. However, there are many reports about an audio bug regarding GH4... Overheating has been a big problem on certain Sony cameras so far, let's see about A7s, but I wouldn't exactly call Panasonic's GH line performance rock solid. You are right about choosing a rock solid camera and that's why companies still offer professional video cameras and not only cheaper hybrid alternatives.

Did you read the article in the first place? Hello, it is about sensor ratings...

Sony's A6000 is so much better than GH4 as a stills camera. I'm pretty sure that it is very close in video as well and all that for less than half the price! Sony is gonna say good bye and get past everybody else pretty soon...

It's funny how some people they're trying to reduce A7s qualities in favor of GH4... It feels urgent to prove GH4 is finally up there with the big boys... Right now 1080p is the reality and in 1080p world GH4 is nothing really special. Even a seriously compromised camera like 5DmkIII from 2+ years ago still holds its own against GH4. As for GH4's low light capability it's still stuck in 800 iso from back in the day... However, I really believe that GH4 is a great camera but a bit overhyped. On the other hand A7s is not out yet so we can only speculate. Enough is enough with biased conclusions, it is just a matter of time before we know what is all about. Be patient 4K is not there yet and by the time it will be there will be much better cameras than GH4, A7s etc.

I didn't elaborate about the benefits of full frame or the shallow depth of field but unfortunately you didn't get the point... I was talking about the A7s 1080p capabilities that apply to present day filmmaking. Please understand that this is an APS-C camera as well in 1080p, so that makes your comment irrelevant about shallow depth of field. APS-C is equivalent to Super35mm the filmmaking industry standard. Regarding 8bit 4:2:2, have you ever worked with C300? Do you think it is not adequate for broadcast? or have you ever seen any FS100 S-log 8bit 4:2:0 in 24Mb/s AVCHD footage? Is it not good enough for most video work? People need to concentrate on what they can properly use right now.

Right now most of us we are going to shoot 1080p for a great many projects and the A7S wins this battle hands down. On paper it looks like the most complete 1080p DSLM ever made, it offers almost everything we have ever asked for... So many, real world, filmmaking capabilities such as full-frame, APS-C, extreme low light, no nonsense decent codec (50mb/sec for 8bit 4:2:0), S-log picture profile, no need for expensive adapters, even 120frames slomo in 720p(by now obsolete...) and uncompressed output (yet only!)8bit 4:2:2. However, most people argue about the lack of internal 4K recording! Obviously 4K is the future but untill our workflow gets properly 4K with respective monitors, PCs, GPUs, TV sets etc. this camera is going to be king for the budget, indie filmmaker. I believe 4K needs a couple of years before it gets industry standard, yet people are already sold to it before they have or can even use it. We've already seen cameras that promise the future and do not deliver now(Blackmagic anyone?) and when the future comes they are already out of specs. Don't forget that next year GH4(another excellent offer) is going to look so... well, last year. Such a shame really!

This Sony ad is very misleading then, such a shame... (about 4K on APS-C) Thanx for opening my eyes.

Andrew have you realized that the Sony A7S sensor reads out image data from every pixel with both resolutions available(4K and 1080p) at both APS-C and full-frame size? Obviously you can use your Cooke lenses... No need to buy a speed booster(an extra cost for GH4 users) and you get the best of both worlds APS-C and full-frame natively. You can adapt a massive number of lenses and you can use the growing variety of Sony APS-C e-mount lenses. Then again every full-frame lens now can be used in 2 different focal lengths within the same camera. An excellent feature for those looking for lightweight packages with small footprint, documentary work etc.
