I used a new FDR-AX100 to take backup videos during a photo shoot last week as I took stills with my 1dx and d800e.

this was my processed nef off a nikon 35 1.4G


this was an ungraded screen grab from the sony fdr-ax100 4K mpeg-4 video

Very impressive. This gets back to the subject of Mark's frame grabs with the AX100. smile.gif

the D4 or even the new D4s are not impressive at all for videos.
the 1DX with less spec has better video.
BUT none of the current full frame DSLRs have videos like these two samples.
looks like an ARRI with zeiss lens

How can they claim the 4K Atomos Shogun as 4K? It has no 4K display, its very misleading & yeah I know it records 4K. There has to be a extermal 4K recording option with out a display. We don't want another display we need external 4K recording options. I guess there going after the heavy pockets first

Do you really think the 4K pro Sony F65 has a 4K display ? There is no 4K display on any 4K recorder live view display.

Clearly there's a market for stills cameras that cost more than $6k with lenses that cost more than $6k or Nikon and Canon wouldn't be selling them. You may not be in that market, but others are. So if all you wanted to say is that you didn't want to spend $6k on a camera or $5k on lens, you could have said something more nuanced, like "Anyone looking for a full frame with maximum iso range and video mode who isn't willing to spend more than $10k total including lenses will choose the A7s over the $6K D4s" or something more personal like, "I'm not willing to spend $6k on a D4s or $5k on a lens for it but I'm very interested in the A7s". Money aside, there's no doubt in my mind that the D4s is a better stills camera by far, and the A7s is a better video camera by even farther.

the best transvideo 8" monitor also goes up to 1080, that's it.

Everyone knows the pro photographers shooting at the Superbowl, Olympics etc with 600mm F4 lenses have either Canon 1D * or Nikon D4 cameras but this thread is about video mode with the full frame A7s. BTW if anyone wants to shoot low light stills with a compact full frame camera I would say the A7s is the way to go.

Precisely. Imagine how much smaller this thing would be without the display that so many users wouldn't need in the first place.

^ That's pretty funny. From what I read, I do think videographers are finding clients more accepting of small gear than they used to be.

The A7s @ 80,000 iso looks great !
Quote:
Sony let me play around with the a7s a little more. While they wouldn't let me put a memory card in the show floor prototype, they did allow me to film the output display as I ran the ISO all the way up to a remarkable 80,000 ISO.

While the Sony a7s doesn't shoot internal 4k, the low light performance on this camera is nothing short of amazing.

What's odd is that his test scene was by no means, 'low light'.

The only thing you can be sure of is that Sony 30" 4K Trimaster monitor is terrific!
At 20K, it should be,

This looks like the perfect low light lens for the A7s !

Full Frame Mitakon 50mm f/0.95 lens to be unveiled on April 20. Costs $799!

Almost three months ago we reported about the first image samples taken with a prototype Mitakon 50mm f/0.95 Full Frame E-mount lens (SAR post here). According to one of our trusted source the lens will now be launched on April 20th! And it will cost $799. That’s $220 more than their other E-mount lens, the 35mm f/0.95 lens for ASP-C E-mount cameras (they are on auction here on eBay) which doesn’t cover the FF sensor area.

While video recording a Sony rep I asked about the lack of internal 4k recording and he told me its because of heat issues that would arise in a body that small. So I guess when the technology gets better, we'll see it in a future model.

SAR: Amazing Sony A7s Low Light test video!
Quote:
Den Lennie just updated his A7s post by including an amaizng A7s High ISO test (Click here and scroll down to see the video). The screenshot on top shows you the noise at crazy 409,600 ISO. This is really a complete DARK(!) room with no light. And the video you will see that actually up to 102,400 ISO noise is acceptable!

I can't say that explanation surprises me, but they did manage to incorporate 4K into the relatively small AX100 body. The A7R is smaller still, so perhaps. But I don't think we can rule out the camera was rushed to incorporate something 4K in response to the GH4. So Sony may just not have had enough time to do things properly in regards to 4K.

Who knows, we may see a new model in 6 months that gets it right.

It is very impressive Joe, but it brings up a question, how many have a need to shoot in the dark? I know some people are actually obsessive about low light performance, and it is important, but really, how much of what we shoot is in such ultra dark environments? Surely not my kind of shooting.

In fact I often find it odd that some get excited when they can make a relatively dark area look much brighter than it actually was by raising ISO, slowing shutter speed etc.

IMO the ideal is to capture that dimly lit room as it was, dimly lit. Personally I don't see the value in trying to render it like we had the sun shining in the room. But I like accuracy and many don't.

So for those that shoot in more typical lighting situations and normally dimly lit environments and who try to keep things 'real', the Sony test is interesting, but I'm not sure how practical.

I shall now take cover as the low light fiends go on the offensive. smile.gif

I forgot to say that he also mentioned that the combination of a big chip and a small body is what can cause the heat issues. As we know, the only other 4K DSLR with a full frame chip is the Canon 1DC which has got reduced for $10,000. That is a big difference in body size and price. Basically even if the technology is their to control the heat better, it would have for sure cost more expensive for Sony to produce it. It's definitely a bummer since you need to purchase an external recording unit but the price of the A7s and Atomos 4K recorder will still be far cheaper than the Canon 1DC. Yes a bit more inconvenient as well.

Stunning video from the A7S. I can immediately see the dynamic range improvement due to the S-Log 2. This footage takes on a very film like look compared to most digital video. I was really hoping Sony would wise up and up S-Log 2 in one of their cheaper cameras.

Ken, the A7s is a showstopper for me without internal 4K recording and my VG900 shoots indoor videos on dim cloudy days with the slow 24-200mm FF zoom @ F11 and 200mm at high iso with no visible noise. The best 4K low light video I seen from the A7s was the one that had some scenes shot at 12800 iso with the slow 35mm F2.8 FE lens @F5.6.

Decision, decision for me now. It is good that I have two options to choose this coming trip. Either A7s or GH4 depending on which one has lower price?

Do you really think the full frame Sony A7s is going to have a lower price than the GH4 ? I bet the A7s will be over $2,000.

^ Joe, and that's before you add the external 4K recorder necessary for 4K recording. So whatever the price of the body, it's going to be a lot pricier than the GH4 that already has that capability.
