I notice that most of the interior is in focus so I would guess that it has a small sensor. The exposure range is pretty good, the highlights and shadows look pretty good.
Maybe a three chip Panasonic model such as the HDC-TM900?
First, imho that is very nice some footage. The sharpness of the images and the dynamic range was impressive.
I would guess it is not your D5100 as I don't see a bit of moiré in any of those scenes.
My inclination would be to agree with Nick Hope that it's a GH2, based upon some recent posts you've made. However, nedski makes an asute observation that it's probably not a dslr based upon the depth-of-field.
So, I'm going to guess it's a 4K camera based upon the "clue" in the OP (resized to 720p). Maybe the JVC GY-HMQ10? Has that been released yet?
I'm no detective but, you did say 'I'm videoing you', indicating he may not have noticed. So i'm going for a DSLR format camera. DOF is deep, so possibly stopped way down, F16.. recording in 1080p downrezed to 720 for vimeo.
Which one? tough question. it has an ever so slight colour tint that we tend to see with the GH2 (its a panasonic thing?), very slight. So i'm going with that :)
I think I was misleading with the phrase "smooth aperture change". My D5100 jumps in levels of brighness when you are shooting even when I'm in aperture priority mode and the aperture size is fixed. I am in the habit about calling any change in light sensitivity "aperture change" even though these days it is more likely a change in shutter speed and gain. This is a habit left over from my camcorder days I'm sure. In this case, what I meant is that the brightness changes smoothly, unlike my Nikon which has to be locked down because it changes in jumps. Not an F3 or C300. Think cheaper.
Just watched a TV programme on ITV british TV here and it was all done with DSLRs. Prime time viewing. You could see the DSLRs in the shots, 2 cams, cut with an overhead none DSLR. Looked pretty good. So if you are getting footage that good on your iPad, the mind boggles whats coming next! Exciting times ahead indeed.
You can get footage of that quality with a phone or a $150 camcorder. Not exactly news.
Like you say, it won't do very well under less than perfect conditions, especially low light and you want to avoid that "I really look like an idiot when holding an iPad in front of my face shooting video" look.
What the future will bring ( e-mail part may already be in the newest top of the line Canons or Nikons ) is editing and e-mailing footage directly from your camera and thus eliminating any need for tablets or phones.
It will be tablets and phones pushed out of the business, not DSLRs. At least out of the portable pro market.
The difference is, Laurence's footage is way better looking quality wise than "Click on line", and thats on a BBC channel. Another bad use of of 'cheap' cameras has to be "The Gadget Show". Both these programmes are great with content (and thats really what matters right?) but the image quality of these programmes is frankly awful! Not sure how they get away with such low bitrate blocky content. This iPad footage looks clean in comparison. So i think thats the point, this is an indicator of whats comming. Phones will get better along with iPads, DSLRs and the rest... all will improve and we will be able to make professional content for broadcast from a $300 device very soon i think (a few years perhaps). But - it will acutally look as good as an F3 or c300!
Time will tell i guess.
I kind of judge cameras not just by the end quality, but by how much light it takes to achieve that quality. With my 1/3" sensor camcorder I can get excellent results indoors, but I need to light things to get that result. With the much larger sensor on my DSLR, I can usually get great results without extra lighting. I have a bunch of commercials I did with my Nikon D5100 and no extra lighting here:
iPad is already obsolete as a photo/video editing platform or anything. It was a logical step after all. You either edit for real on a laptop or a workstation or if you need on the spot edit and send you use something that really is portable and shoots better images/videos in the first place..
That's just the beginning. We'll probably see GH2 quality portables with on board edit/send features within 12 months. maybe GH3?
Just a matter of time. Flip out screen on the GH3 or 4 becomes an android device and you have a real camera with basic editing features and wireless on board. The only thing left to figure out is how to safely dispose of all those useless tablets.
