  1. I've also been thinking about this. But I think it's way too difficult...

    modern sensors in compactcameras are 4K capable. Yet no compact offers 4K video. I think it mostly has to do with the processing power. I don't think a raspberry pi would be able to get 4k video from the sensor and encode it into some usable format. I suppose the most difficult part would probably be making the firmware and making everything work together.

    Look at this 12 MP 1/1.7-inch Sony sensor for example: http://www.sony.net/Products/SC-HP/cx_news/vol69/pdf/imx144cqj.pdf
    It's been used in the newest compactcameras, like the Samsung EX2F, probably the Nikon P7700 and maybe more.

    The sensor specs: 35fps at full resolution. It also has a 4K video mode (4096H x 2160V) at 60fps. Sounds lovely.. But cameras that use this sensor aren't capable of such things.
  2. I'd love to shoot raw.

    As a still shooter I'm used to the raw format and wouldn't want to do without it. But it will take some years before raw becomes 'doable' for enthusiasts like me. Spending $3000 on a camera is not the end on then world. The investment in a extremely powerfull computer and huge storage arrays I can't justify for myself.

    If you make a living out of it or are very passionate and ambitious about what you do, then this is not such a barrier.

    It will just take some time. I think the advancements in computing power and storage size go faster than camera technology. In a few years things will look different and raw will become more accessible.

    Definitely not a 'no' to raw, but even though the camera is affordable now, the complete picture is still out of reach for me and I think the same goes for most enthusiast dslr shooters.
  3. Read this:

    If you still want to go for Canon, the 650D doesn't add much extra imo. Unless you want to use autofocus. But if you want to get serious with video you probably want to use manual focus anyway.

    Actually Sony is too late with the VG900. Sure it is potentially the best video using a dSLR sensor for under £2.5k and probably arrive in stores early next year. Why? It is because RAW capable video camera already can be had for under £2.5k even though the sensor is small such as the BMC by next year we may well see S35 version for around £3k-£4k be it from BMD or another manufacturer.
    Canon was'nt smart with their $15k FF EOS cinema standard dSLR and as a great believer of "you pay for what you get" I doubt the VG900 will come anywhere close in video quality. The VG900 will only be a modest improvement over the 5DIII and as a dedicated camcorder for the price even with FF sensor it will have a hard time challenging BMC and Digital Bolex and may prove a disaster for Sony.

    The VG900 sounds more like a high end consumercam. Like the earlier VG's. I myself for example am interested in such a camera. I'm not interested in RAW (yet), because that means buying a new computer, a huge amount of hard disks to store everything and ssd's etc.

    I think the market for video enthusiasts is pretty big. Probably bigger than the professional market that really wants RAW.
  5. Depends on the lens I guess. But you should be able to calculate it with the crop factor. For example, my 1,75x anamorphic works with 40mm on my GF3. This has a 2x crop factor, the BMC has 2.3, so on the BMC it should work (and give the same fov) with a 35mm.
  6. Ah I see the point. It's 2/3 fstop indeed.

    Fuji X to M43 is impossible, because the flange distance from the Fuji X mount is shorter than M43.
    Samsung NX is 25.50 mm vs 19.25 mm for M43. So it in theory it should be possible with an adapter.

    Also confirmed here: http://www.similaar.com/foto/lensmount/lensmount.html

    Anyway, i can't find such an adapter either, except for a rumor from 2010..

  7. I bought a Minolta MC Rokkor 58mm f/1.4 on eBay and gave it a spin with my ISCO Projection Anamorphic. I wanted to see how it handles big apertures.

    These are still images (Panasonic GF3). Most of them at f/2.8. I put in one shot at f/1.4. The photo's look really sharp to me. I also got footage, i'll be putting it together and posting it later.

    [color=#0066cc]3rd test: Even more so. 1DX is bext full frame DSLR.[/color]

    I think the 1DX footage is too much sharpened. There are a lot of sharpening artefacts. Look at the wooden poles around 18 sec. There is a distinct white line around them and even the background (which is out of focus) looks oversharpened.

    In this case I prefer the 5D3 with less artefacts.. but I guess it's a question of post production.

    Sony just announced the NEX-EA50. It comes at a complete surprise, haven't seen any rumours about this camera
    before. Which is surprising since everything Sony makes seems to be known months in advance.

    16 megapixel APS-C (shoots raw pictures too)
    E-Mount
    New 18-200mm Power Zoom
    1920x1080 in 50p/25p/50i or 60p/30p/24p/60i
    AVCHD 4:2:0 at up to 28Mbps
    Two-channel XLR audio
    ECM-XM1 Shotgun microphone is included
    Linear PCM audio; time code; user bit; and built-in GPS
    Sony’s HXR-FMU128 (128GB) flash memory unit can dock directly to the camcorder for simultaneous backup

    [u]No built in ND filters[/u]

    [b]And the best: Price 2740 GBP[/b]
    Especially considering it comes included with a mic, monitor/viewfinder (can't find info on the resolution though) and a formfactor with shoulder mount etc so you don't have to spend much on a rig..

    Available from October.

    I'm pretty new in the video world, but this looks seriously awesome to me. What do you think?

    I visit this site quite often because this site offers unique perspectives, not distorted ones. Now, I am a bit uncertained... There are so many of your previous articles praise the hack, and how the hack makes a huge difference... suddently, it is underplayed, potentially because it's done by someone with whom you disagree...

    I'm pretty sure Andrew doesn't mean it in _that_ way.

    I think he's saying the GH2 is pretty awesome even without the hack - still, the hack makes a big difference. But it's the difference from very good to great.

    The difference with a unhacked and hacked Sony potentially could be much bigger. But that's just because the Sony's aren't that good for video from the starting point (and the GH2 is).

    Oh you guys. I think if he wants to use AF and it's been working for him for the most part, just let him use AF. What's the big deal? Anyway, I have no idea what might be causing the issues off hand. Are there any common circumstances between the shots where it fails? Like, Low-light situations, moving at higher speed then usual, or low contrast in the shot etc?
    [/quote]

    Nobody is forcing him to stop using AF, but I'm pretty sure it's just a fact that AF is never going to be perfect in a situation like this.

    So if you want to use AF you have to accept the fact that sometimes it will hunt, no setting is going to change that.

    It's just the way autofocus works. It needs contrast, there might be a moment when there is not enough contrast on the AF points, the camera will lose focus, it has to start searching and the hunting starts.
  12. My first steps into the video world. I've been photographing for 10 years but found a new hobby in video :)
    This clip is made for the [url="https://vimeo.com/blog/post:513"]Vimeo 'Magic Hour' Weekend Challenge[/url].


    [media]http://vimeo.com/47478586[/media]

    Used my Panasonic GF3, learning to work around the limitations (no manual exposure).
    I hacked it with the EOSHD 44mbit hack for the GF2, seems to work fine.

    Lenses: Minolta MD Rokkor 135mm f/2.8 and 28mm f/2.8 with adapter.
    Some light colour correction (white balance / curves) in Sony Vegas.
