An interesting new camera for UFO Hunters?

Hi All

This may be of interest to all the UFO hunters on here Sony have launched a new camera called the A7s it's a full frame mirror less 12mp camera it takes interchangeable lenses and due to the short focal plane distance (distance from lens flange to sensor) with the use of adaptors ALMOST any camera lens can be attached and used in manual mode Canon,Nikon,Leica etc etc but what is really stunning is the low light performance watch the video below moonlight and a camp fire.

If it picked up something good, it'd be dismissed as a hoax anyway. Unfortunately, we are at the point where we can make fake footage in convincing fashion.

That looks like an awesome camera. I wonder how much it will cost, is it out already? I have some older lenses I wonder if they would work. so they are turning up the ISO? what is that, is that where they get more light?

That is stunning, blew my mind a little, would like to do some tests on that, it looked like daylight when they put it on the highest settings, confused me how they have done this because all the colouration was there, this was nothing like low light photography I have ever seen before, are you sure the footage is genuine? actually take at night, I am thnking it is Sony so it must be genuine, but my mind is screaming fake when I watch it.

I will have to look into how much these cost, probably a damn sight more than my wages will cover

ISO is basically a reflection of a camera's sensitivity to light.
This camera's ISO is... off the charts. For a point of comparison, a Canon 50D Mk II (which is a professional-grade camera) has a maximum ISO of 12800.

The camera in that video maxed out at 409,000, which is... ridiculous. Ridiculous and awesome.

Awesome. Thanks for bringing it to the forum. I have a bunch of Sony lenses that I was using for a VG30, which I was disappointed with (wishing I went for the C300 instead...) but now I might have another use for them.

That video was awesome! After a little search, I found this Comparison Chart of A7, A7R, and the A7S It provides a nice rundown on these Sony cameras, but still the price for the A7S is unknown. By reducing some of its other features in comparison, do you think it may still be in the viable $2000 range?

With iso that high im worried about how well you will be able to see anything far out....might possibly be grainy but that is highly impressive considering most nights will have moon light or star light....

Yes its real if you look at sonyalpharumours you will see still images at 12800 iso with almost no noise.

In this case keeing the mp count small on a full frame sensor means the pixel size is larger and noise is greatly reduced.

Well a few of us are keen photographers and tech like this would help what would be good to see is your typical youtube light in the sky ufo video on a normal camera and with this camera side by side.

That's pretty amazing! Could I ask what might well be a stupid question, though? With that much gain in the dark areas of the image, how come the fire itself isn't totally overexposed? I would think that if the grass goes from totally black to clearly green, the fire (which is visible in the dark 1600 ISO images) would be glaring out bright white! Is there some kind of clever filtering going on in addition to the absurdly high ISO? Or am I missing something through not having sound on this PC?


Edit: maybe this explains some of it: a comment on the YouTube video:

Up till iso 100,000, everything looks fine and dandy. Anything above that is an 'expanded' iso, meaning it's digitally brightened from the shadow areas, i.e. no actual pixel detail is gained from it.

exactly my thoughts looks like there just skipping ahead an hour each time......

That can't be the case - look at the clouds. If the lightening effect was down to the passage of time then the clouds would move a lot more than that!

Well have a look at these then!!!

WOW indeed! But what is the noise level at larger shots? I would love this for some sky shots!

Happy to help SONY A7s iso test

Now is a chart containing 100% crops of ARW files converted to JPEGs with no adjustments.

That's a very impressive sequence. I wonder what the scenes are like when the camera is not static though.

well since it is a piece of video. The camera is static, most of the scene is static except for the man and his kippers, and the fire and smoke, perhaps the ideal situation. I'm actually looking right now for a full motion scene, with camera on the move and plenty of different lighting, and moving subjects, just to see how that er, pans out.

BTW, did get get a tenuous price for it of £2500, maybe around $3000+
An update on that,

Den Lennie is the man who did the video for Sony, he's pretty impressed with the camera. The link below is a sequence at full ISO in practically complete darkness, so there is noise, but it is not ambiguous to look at. For the full 4K cinematic resolution experience the camera video needs to be downloaded to a hard drive suite. Still haven't found other video in the blackout and in motion though.

I see you have the last link, I'll leave it in anyway.

Well to be honest in most situations if I had one I would be static , or it would be used on a tripod for low light stills/ timelapse work.

Pictures of the Milky Way etc would be interesting on this although you need the hard disc recorder for 4K it will record full HD to an SD card.
