    • GH5 Prototype
      If that is the case, I may mess myself a little.
    • GH5 Prototype
      Discussion on Newsshooter 13 comments Photokina 2016: We ask Panasonic all the questions about the GH5   Will ; a reply to Mark Ellsworth 4 days ago "Right, but the micro43 standard is rather open about sensor size and aspect ratio. Crucially, the standard requires that the imaging area of the sensor be a specified diagonal measure. All Micro43 cameras but two have featured identically sized 4:3 ratio sensors. The GH1 and GH2 featured larger sensors that covered that diagonal in 4:3, but also 16:9 (and necessarily, 3:2 as well). Because lenses produce a circle, standardizing the diagonal ensures that every lens will still cover. Understand, this is not the same as generating 16:9 or 3:2 imagery from a 4:3 sensor, where you just throw away some of the pixels from the top and bottom of the 4:3 imaging area. This involves using fewer pixels on the top and bottom, but also additional pixels on the sides. So your 16:9 image is both shorter AND wider than a 4:3 image taken with the same camera. As regards video, this means that the effective sensor size is actually bigger, and the "crop factor" is thus less. The "crop factor" of the GH4's full sensor is 2, but the 4k video in the GH4 uses only some of the full width of the sensor, so the crop factor ends up being close to 2.3. In the GH1 and GH2, the larger 16:9 imaging area resulted in horizontal crops closer to 1.8 or 1.9, if I recall correctly. So the GH5 may be a return of the multi aspect sensor. And if it is, this would explain a few things. Namely the 6K photo mode. Nominal 16x9 6K (not full DCI spec) is 5760 x 3240, much like we call 3840 x 2160 4K. A 4:3 sensor with 5760 pixels wide would be 4320 pixels tall and thus a 24.8 MP sensor, quite different than any yet seen in Micro43. But if that width is only in 16:9, the 4:3 imager would be 20.9 MP... slightly more than half a megapixel more than in the GX8's sensor. So with a minimal reduction in pixel size, this theoretical multi-aspect sensor is possible. In addition to the benefit of 6K photo mode, there's more magic in a 5760x3240 16:9 imaging area. That size is exactly 1.5 times wider and 1.5 times taller than 3840. 1.5 is a kind of magic number in this regard. Oversampling by a ratio of 1.5 allows for computationally easy downconversion with improved color accuracy at each output pixel. Don't take my word for it either: you can look at the specs for every different version of the Arri Alexa, which generates its 1920x1080 from a sensor with 2880 x 1620 pixels (which it now allows you to record all of, a compromise in the original design that attempts to eke more resolution out of the sensor at the expense of color accuracy). In summary, it doesn't take much of a leap (basically, just Panasonic returning to multi-aspect sensor, and developing a new sensor design with pixels only marginally smaller than their current generation) to arrive at a possible GH5 with internal 10-bit 4:2:2, a horizontal crop factor of 1.8 or 1.9, vastly improved color accuracy in video (in addition to the greater color sampling rate), and a true 16:9 6K photo mode with no interpolation or computational trickery". Pretty interesting post by Will on Newshooter. He might have sort of a answer on sensor size of the GH5. Food for thought..
    • Canon C500 Is it worth 7K new?
      This is just an assumption, but I would think that they (as in Atomos) are trying to support the Canon cameras as well as Sony Cams. You can see this with so many firmware updates even with the original shogun - constantly saying the C500 is supported (with this or that update) is kind of encouraging. Also, they have more than one 3G SDI inputs now in the inferno, compared to the single input of the original Shogun - its more suited to receive dual signals. May be its not a perfect solution, but its something... not that I'm trying to defend them, but Odyssey is sounding more and more out of my reach as I read on it... The downside of the Odyssey: -After you purchase your Odyssey for $1795 - you have to pay an extra $999 for the Canon RAW license. -Even if you say... hey... $2795 is nothing... I'm already there... from all I'm reading... when you record Canon RAW - its literally 1hour = 1tb. So 2 hours = 2 tb, in comparison, you can get 8 hours with the 1DC on 2tb. So, how many SSDs are you buying for this beast? -Speaking of SSDs, Odyssey's SSD support is limited to their proprietary ones and Samsung's SSD???? -And this is the single biggest deal breaker for me... its not portable. You are looking at third party solutions of V-mount, D-tap, some third part company that will add battery plates to the odyssey... I think the cheapest add-on plate is $89 bucks... but the price of batteries is not cheap. I'm not going to list the upsides/dowsides of the Atomos, but it comes with 2 sony batteries and its hotswappable Nonetheless, whats really bugging me right now is the following statement: "Some of the links I posted above go into the specifics and unique attributes of Canon cinema RAW, which is quite different from almost any other RAW implementation since the Canon RAW has much larger data rates (moreover, ISO is baked-in and white balance is set)." Am I reading this right??? Its RAW with large data rates, but ISO is baked in and WB is set? How is it RAW then? Or rather what makes it RAW?    
    • Rectilux Core DNA - non-rotating single-focus attachment for anamorphic lenses
      Good choice in taking lens, I've found that Super Taks are a great sharp taking lens with Anamorphics. As far as the extra stretched background, that's a bonus - oval out of focus areas is why a lot of us use anamorphics (Yes, it's not the flares! You get over them very quickly once they ruin a great shot & by ruin, I mean obscure what you really want people to be looking at, & yes that's not the flares).
    • Canon 6D vs 5D MkIII vs 7D MkII for filming with EOSHD C-Log
      Visioncolor's profiles, for Canon, are the best i've ever used, VisionTech being the pick of the bunch - only needs minor tweeking & you're done. As far as BM cameras are concerned, they are 10bit Prores & not 8bit H264 - so of course their Film profile is going to be miles ahead of the majority of cameras on offer. However, if you haven't got the time to learn how to shoot a proper camera, then their Video profile setting has been vastly improved from its humble beginnings & produces a great image if you simply don't have the time to grade a lot or are used to grading 8bit H264 (NB. The bonus being that it won't fall apart like H264, because it's still 10bit ProRes). The real problem with the Micro, it seems, is that improved battery & 60p simply doesn't seem to out weigh the bad ergonomics - whatever that is meant to mean for a drone camera?
