  1. Also guys don't forget this is a pre-production firmware, v0.5 not the final one which will ship to customers.

  2. Er...Tony...I'll be making a movie on this China Anamorphot or one just like it...15 minutes of messing around run and gun is EXACTLY what we needed to see from day one with this thing, and we need to see more of it from other adapters.

  4. As usual Andrew, your "test" shows not only the camera's capabilities but your great ability/creativity. Well done :)

  5. beautiful. I think I fell in love with your model a couple of times throughout the 2.5mins. rather than a test showing the camera image quality (we all know what great 1080p/2k and dr from cameras shooting more than 8bit h264 looks like), the piece actually highlights how use of lenses designed for the image plane they're being used on create their own amazing look. those 16mm lenses do marvellous things to the image. No other camera / lens combination would have allowed this piece to look the way it does. - the horrific black magic pocket may have been cleaner, but the shutter skew and stupid form factor would have hindered just about every creative decision you made that day. I can't afford one of these at the moment but will be sure to keep an eye out for one when they come down a bit in price.

  6. @tonyw Those blue flares aint blue flares mate. They be blue ghosts :) Internal reflections and all that... Yeah, Blue ghosts, which makes this the perfect adapter if you wanna make a PacMan movie. No kidding. Andrew Chan must be cringing if he has seen this, no comparison to the shorts put up by Sebs and elubes

  7. Stuart, I see you've met Gollum. He wants to talk to you about his precious. He might actually have less practical experience than a babysitter working under the 2nd AD and so he clicks "like" and takes his opportunity to commit irony. He must have been lost in trance, staring into his collection of glass. I expected his emergence from the shed earlier.

  8. Just when I think I've looked everywhere, I find another source and another video...one of the better looking things I've seen with the Letus, but weirdly, suffering from artefacts I'd expect to see on my LA7200. No silver bullet that says, 'buy it', yet. Still torn between diopters for the LA7200 (almost there Tito, sorry), and an SLR Magic...or both.

    Simple question about 4k

    Nyquist-Shannon sampling theory shows us that we need twice as many samples as our target frequency to prevent aliasing. This is true for audio and video and all sampled systems. For example, 48kHz audio can reproduce 24kHz without aliasing. All frequencies above 24kHz must be filtered during recording and playback (in practice higher sampling rates are used to allow for lower cost analog filters). For video we're sampling light instead of sound and the same theory applies. 1920 pixels can represent a max of 1920/2 = 960 'pixels pairs' (on/off) before aliasing. For example, a chart with black and white vertical lines can be used to measure 960 lines pairs from a 1920 image. Even if the camera sensor and chart aren't perfectly aligned, we can see 960 line pairs. When looking at even higher resolution lines, we can see more than 960 line pairs are visible, but with aliasing artifacts (e.g. on the right side of the vertical line chart): http://www.graphics.cornell.edu/~westin/misc/ISO_12233-reschart.pdf Top cameras have optical antialiasing filters which cut off frequencies effectively above the sensor aliasing frequency. These cameras exhibit very high quality images, especially important for moving images/video. While aliasing can provide a false appearance of higher detail, it's one of the give-aways the image/video is not film. If the aliasing is very high frequency, and the image is somewhat noisy, it's not as apparent (e.g. BM cameras with no AA filter). Again, top cameras have very good AA filters (changeable/removable) such as the ARRI Alexa and Sony F55. When looking at a chart we see excellent low-aliasing. The TM700 was the top camcorder (by a quite a bit), IQ-wise in its price range when it was new. 3x 2.53Mpixel sensors (no debayering or related artifacts!), Leica DICOMAR lens (F1.5 - 2.8), 1080p60 support for slowmo, an excellent power OIS, decent audio quality with an external mic (indoors- only neg. issue with camera is fan noise picked up on internal mics). It wasn't very good in low light, however a simple LED light on top of camera, with a shotgun external mic makes a nice ENG/interview camera for any lighting condition. I still have mine but haven't used it much since getting the 5D3. The 17Mbps AVCHD codec while pretty good is a bit over-compressed for large motion scenes/handheld, etc. (60p is 28Mbps). An external recorder might help but I haven't tried it. The zoom range is very impressive: 35mm-420mm (35mm equivalent). With power OIS, even at max zoom, image is pretty stable. Walking while shooting also works very well- no rig needed! :). The autofocus also works pretty well (easier for small sensor cameras). http://shop.panasonic.com/shop/model/HDC-TM700K?t=specs&support#tabs The TM900 is a newer version with slightly better IQ (looks like more contrast): http://camcorder-test.slashcam.com/compare-what-i-cmp-u-cmd-i-view-u-mode-i-docompare-u-lang-i-en-u-id-i-167-y-185-u-name-i-Panasonic%20HDC-TM900-u-bname-i-Panasonic%20HDC-TM700-u-cmd-i-vergleich.html Note comments: "Sharpness and color at the AVCHD limits". Thus the 4K GH4 with one of Panasonic's OIS autofocus lenses should be quite spectacular for doc/ENG/(narrative- some shots).

  10.   Refreshing to get a camera that is actually exciting.

  11. Cinematic-ness probably can be broken down to this: Color balancing with priority given to skin tones Lighting and adjustments to shadows and highlights to mimic the dynamic range of the human eye. Motion blur you get with 24p, People say it's because we got used to 24p in the theaters. I think it's more than that. Motion of 30p and above and can steal your focus/attention from the subject. Cross processing for complementary colors.(usually in the bounds of natural looking skin) The wide aspect ratio. And maybe reduction of chroma noise to make it look more like film grain, but that's only when noise/grain is desirable in the shot. All these are adjustments to make the image look natural and pleasing to the human eye, because images straight out of the camera look entirely different. If you miss one of these points, it starts looking to what some people may call un-cinematic. And sure, you can deviate from this if you know your limits or if you are doing something abstract. So far, it seems Panasonic is more willing to deliver better out of the box results. Canon is always trying to decide which feature to leave out so they can sell their more expensive variation.
