10MP Ultra Lowlight Camera possible

I'm not sure about that lens. The lens specifies "Image format 1/1.7" which is pretty far from 4/3". Also I'm not sure if M43 and CS lens mount types are equivalent?

Anyway it looks like that camera, a good lens, and weatherproof enclosure would cost close to $1000 all together. I'm sure it makes fantastic video though!

According to this doc below they show 2 lenses, DH-PFL085-J12M and DH-PFL12-J12M. They don't list any specs.

http://dahuasecurity.mx/download/2017_V1_4K_starlight.pdf

The specs sheets all say micro four-thirds mount, but not sure if they have electronic contacts and power for autofocus and aperture control. If they did have electronic contacts on the lens mount then it'd be compatible with a wide range of micro 4/3 lenses already out there from olympus, panasonic and others.

They list the sensor sensitivity specs with a lens aperture of f0.95. I presume the lens they used was Voightlander Nokton series of lenses, which costs as much as the camera.
 
Actually you can zoom in on the PDF, the lenses seem to be fixed focal lengths at 8.5mm at f/2.8 and the other 12mm at f/2.0.

If you think of 35mm cameras focal lengths, equivalent to 17mm lens and 24mm lens, respectively. Those lenses appear to be manual iris and manual focus.
 
If you really want wowing look below (comparison of normal non starvis vs 4K 35mm Starvis with ISO 409,000!!)

Only issue is it's incorporated into a box camera and costs £6,000 excluding a lens! Unsure which sensor it uses as it's listed in the specs as only a 4K 35mm starvis exmoor.

Recommend viewing it at highest resolution and full screen.

The Vb770 is probably using the same sensor in the Sony A7S II camera with better cooling for 24/7 usage. Plenty of night videos on youtube on the a7s and a7s II, though the bitrate on those videos usually record at 200mbps.

Those were my initial thoughts although being CCTV, I wasn't sure if there was a security equivalent sensor under development. Either way, it would be fantastic if it could find it's way into IP cameras albeit at a far more sensible price.
 
That's a rather steep price for the SNC-VB770... From Sony's point of view, the 4/3 sensor in the IPC-HF8835F may very well be intended as the budget sensor in comparison :)

Either way, I booked a IPC-HF8835F. Not sure what lens I will go with yet though. I asked Andy if he has any pricing on the DH-PFL085-J12M and DH-PFL12-J12M yet, but I may just grab a cheap EF to M4/3 adapter to begin with so I can use my SLR lenses to play with at first.

PFL085-J12M 255USD
PFL12-J12M 355USD

Too expensive, but so the total cost for a camera is around 1000usd, LOL.

No offence but unless it needs it's own special housing due to it's unique shape or size, that doesn't add up.

The retail cost of a SD49225T-HN lite series turret is @ $340 including the sensor module.

Assuming for a second that the sensor module costs the equivalent of $100 retail, that prices the turret unit itself minus sensor at $240 retail. Therefore surely if you were as a manufacturer to build a PFL085-J12M into the turret, the retail equivalent cost should be ($340-$100) = $240 + $255 = $495, not $1,000.

Still expensive at $495 though.

I'm not sure what items you are adding together, but the PFL085-J12M for $255 is just a lens. I think Andy was saying a $700 box camera and a $255 or $355 lens = avg $1000.

These lenses are for the 4/3" sensor used in the IPC-HF8835F, not the 1/2.8" used in the SD49225T-HN.
 
I've ordered one, but have not received it yet from Andy. According to the some of the drawings in the manuals and online it shows the proper contact points for the m43 mount. I'll test that out once I get one in to see if auto focus and aperture control are available in the firmware.

Hopefully since this is a purpose built 4/3 sensor for 4k that there is no crop factor in focal length other than the 2x multiplier for m43.

I look forward to hearing of your experience with this camera. With the larger sensor size, I expect depth of field to be correspondingly smaller for any given aperture. So it may not be able to get everything in sharp focus, especially if you want 8MP worth of detail. Unless it has good auto-focus tracking.
 
I suspect during the day the aperture will stop down so the depth of field will be very deep and almost everything would be in focus. However, at night with the lens wide open, the depth of field could be pretty shallow and deciding where to focus on would be an issue.

It'd be great if the face detection AI tracking would enable autofocus at night, but then again, even regular DSLR and mirrorless cameras have problems focusing in low light, and even more so in AF servo in movie mode.
 
The ready date is Dec.5th, i think this week should be ready. There has 2 guy booked this model one is from USA, another is from DE.

The cost of the glass aside, the depth of field at an Fstop of 0.95 makes the metric mostly irrelevant to the real world operation of a CCTV camera. They also list the figure at 333ms shutter speed. Unless your target is going to stop dead still at a known point for at least 1/3 of a second then you are never going to take advantage of those numbers.

I agree. Realistically, you're going to want to restrict both aperture and shutter speed to above the minimums which in turn means you're not going to get as low a light performance as advertised.

That said, in low light of say 0.1 lux, the figures may be far more usable. Difficult to say without either detailed specs or a test by someone with one. Ultimately the focusing ability will be critical as well.
