Yet another Sony A7S Low Light Video - Wedding Party

This time I've shot clips as high as 204800 but applied some NeatVideo.

Honestly - ISO 204800 with Neat Video outperforms my old Canon 550D (T2i) at ISO 1600.

Its insanely good.

Re: Yet another Sony A7S Low Light Video - Wedding Party

I'm certainly impressed by much of what I see coming from the A7s in high ISO modes, though for me the body has no value until I can record 4K with it since I'm very happy with the C100 in low light and GH4 for 4K in good light. Once we have a viable option for 4K from a high ISO monster then things will change. If only Sony had added internal recording.

I shot a couple of interviews last week in 4K and the ability to zoom in post is most welcome!

So, the Sony ISO @ 50K, 100K & 200K even with Neat Video is pretty damn good and would be awesome in even low light corporate shoots!

Re: Yet another Sony A7S Low Light Video - Wedding Party

We should try and get a sub-forum for this camera as a lot of us seem to be using it - I shot an entire evening reception last night with my 24-105mm f4.0 and it pretty much damn near sees in the dark. I do have a rew issues I need to get to the bottom of - one is how the exposure can adjust as you turn recording on - seems to be a couple of stops but it may be my lens/adapter combo. I also have weird posterised flashes with some DJ lights.

All in all though I love this camera - has solved quite a few issues for me.

Re: Yet another Sony A7S Low Light Video - Wedding Party

Peter, I used to take a light rig in the car with me to weddings just in case. I regularly would be in discussion with the band or venue about what the light levels were going to be. On a few occasions, lights were turned off without notice.


Now..... I don't give it a single thought!!! Bliss!


And yea, the dynamic range, EVF, zebras, and focus peaking are also very helpful!

So glad I splashed out!

Re: Yet another Sony A7S Low Light Video - Wedding Party

I am wondering if Sony just couldn't squeeze the 4K record capability into the body just so they could have it as compact body as possible . At least they should have offered an accessory option like a grip that accommodates a couple of batteries AND the 4k electronics in the grip to record 4K. That is the only reason I'm not buying into that camera. The shogun accessory is not only expensive but adds considerable size to the rig. No cigar this time.

Re: Yet another Sony A7S Low Light Video - Wedding Party

4K for weddingvideography is only useful now for it's cropping abilities in a 1080p project, if you absolutely want that then yes, the a7s is an expensive camera if you combine it with the shogun and there are much cheaper options, a a7s you would get for it's full frame and lowlight capabilities, it's plenty sharp to be useful for another few years, even at "only" 1080p and especially for weddings.

Re: Yet another Sony A7S Low Light Video - Wedding Party

People keep talking about the price of the Shogun to get 4k. But surely the price of the combo is reflected in its superiority? You can't really compare the GH4 with the A7S plus Shogun. The quality is superior in many areas, and thats why it (rightly) costs more.

The setup however might make it more impractical for weddings, but not an issue for any other video work.

Re: Yet another Sony A7S Low Light Video - Wedding Party

Right. I like many others only do weddings and having to put up with the shogun in terms of size alone would negate any small size and weight advantage the A7s would have. If that shogun is mounted within the rig along with mic and batteries and controls then we are back to square 1 looking like robocops again and being as undescreet as possible. Shooting weddings does not allow the advantage of having lots of gear regardless of size and weight, compared to a commercial shoot or any other video work where almost everything is controllable and rig size is not a concern. GH4 has almost everything except FF and lolight, Sony has almost everything except 4k rec inside.
If only that AX1000 had the A7s sensor with interchangeable lens mount..........

Re: Yet another Sony A7S Low Light Video - Wedding Party

Its a Laing P-04. Pretty good value, but truth be told - I'd recommend a Glidecam instead. I had issues with Laing. They did however send me a new gimbal which seems to have it working better now.

I'm hoping to see some 3-axis calibrated stabilisers come down in price enough to have a look at though.

Re: Yet another Sony A7S Low Light Video - Wedding Party

Well then, does anyone make a small 4K recorder without the monitor, like a small tethered SSD the size of a cigarette pack that either is screwed onto the bottom of the A7s or is velcroed to a shoulder rig, ?
What other compact options for 4K rec are there at this time ?
I am itching to purchase the A7s but this issue is delaying it.

Re: Yet another Sony A7S Low Light Video - Wedding Party

You have a dead pixel near the center down a little to the right. You can forward the clock one month for it to remap, A7s does it automatic every month. On another topic, I also have problem with certain DJ LED lights giving bad artifacts, anybody seen it yet?

Re: Yet another Sony A7S Low Light Video - Wedding Party

Sorry if this is a bit OT, but does anyone have any insight or feedback in comparing the Sony FS100 w/ the A7s?

Looking to possibly get one of the two, and just prefer the videocam body & not the DSLR. Just total comfort & preference, not knocking it. I'm a bit old school I suppose.
