  1. Fast apertures on the GH5 = Full frame

    You're like 90% of the way there. See if this doesn't help: The following examples would provide the exact same image, and therefore are "equivalent" assuming the camera is always in the same spot. On a M34 sensor: A 25mm 1.4 lens (and it doesn't matter if the lens was made for FF, APSC, or M43 - this is important) On a M43 sensor: A 50mm 2.8 lens, speedboosted (pretend it's a 0.5X speedbooster). (This is because you're now actually putting a 25mm 1.4 lens on the M43 once you've added the speedbooster, just like #1) On a FF sensor: A 50mm 2.8 lens - - - For #3 the ISO will have to be multiplied by the crop factor squared to get the same exposure. - - - I ran out of likes for today but this is very important for new filmmakers to know I used to think this but focal length has nothing to do with perspective, only the location of the camera and the relation to the objects in frame. The easiest way to test this is to shoot a camera at a chosen focal length, say 50mm, and then shoot from the exact same place with a lens with 2X the focal length (a 100mm lens in this example). Go into an editor and compare the full shot at 100mm to a 2X crop of the shot at 50mm. They will be the exact same image. This is no different from shooting a FF camera at 100mm and a M43 camera at 50mm. This shows how the perspective never changes if you don't move the camera, no matter what lens you're using. Seriously, try it out.
  2. B&H Flash Sale on the Sony UWP-D11 Wireless for US$399

    This is one of those deals where you don't need one but keep the mouse hovering over add to cart anyway... I agree these are great. Better than the Senny's in the price range for sure.
  3. How would you grade this?

    I've had a bad headache tonight and messing around with this provided some nice distraction Glenn so thanks. In no particular order we have- The quarter pounder with cheese: Didley Scott: Let's kick some ice: My only attempt at subtle: Mr Anderson: Aaaaand finally, "Michael get-out-of-my-edit Bay"
  4. NX1 dynamic range in 2018

    Pretty sure any camera can do SCROTography if you just point it in the right direction
  5. Guess The Camera!

    So where do I claim my prize @Benjamin Hilton? Do I just send you my address or how does this work?
  6. Guess The Camera!

    Love these games. Looks like Panasonic so I'm going to go with GH5 or EVA.
  7. Cine 4 - The terror

    @Don Kotlos & @Geoff CB Why Cine 2 and not Cine 1? Isn't C1 nearly identical to C2 but it goes all the way to 109 IRE instead of 100?
  8. Existential Career Horror

    I understand the fear, but luckily reliability, creativity, and being an easy-to-work-with person trump "free" in the long run. I've been slowly and steadily increasing my rate despite the barrier to entry getting lower and lower, and it's all because I focus on delivering more than just the video. Ever since the 5D2/7D/T2i got popular there have been clients unwilling to pay for videos, but those aren't the clients we want. Clients who are worth it will be looking for things like consistency and long track record, so as long as we keep working we'll always have that leg up on the new kids on the block. Having said that, we can't ever get complacent or sloppy or we'll get chewed up and spit out faster than you can say "vertical videos suck."
  9. I lost my GH5! - Please help answer this!

    I'd definitely try to find an S that fits your budget. Over the A7, the A7S will have a bunch of extras like 50Mbps XAVC-S, 4K out over hdmi, 120fps @720p (1.5x crop), and of course the god-like ISO performance. It really is one of the cleanest images at base ISO anywhere. I may never sell mine.
  10. Dynamic Range of ML RAW vs h.264 / h.265 Cameras?

    @Mark Romero 2 5D3 raw is best used for passion projects with long turn-arounds. The workflow is time consuming and the storage requirements are super high. You also won't get much more dynamic range over h.264. On a sensor level we're talking 11.7 stops max vs 14.5 on your D750. If you're shooting at ISO 1600 or more though they're all similar in dynamic range:
  11. The Canon C200 is here and its a bomb!

    Trick question everyone knows professionals don't use autofocus in the woods.
  12. Canon 5D mark iii RAW video 2018

    Had a go with the 3.5K: You basically have to shoot blind, and hitting focus is up to the camera gods... The only thing about using Resolve over ACR is there's no "remove chromatic aberration" button and you can see it would have been useful for this.
  13. DJI Mavic Air First Impressions

    That was at ISO 100? If so that's really not impressive. I'm sure some of it can be graded away but that severely limits the useable dynamic range. It's interesting how they're encoding. The GOP is HUGE. Definitely would worry about fast moving shots falling apart.
  14. DJI Mavic Air First Impressions

    Didn't realize you had one. Me too. So what made you get the Air? I don't think I can ever use a drone anymore without at least the 100Mbps h.265... It's game-changing.
  15. DJI Mavic Air First Impressions

    Thanks for the write-up. I'd be interested in seeing some footage if you have any. You've got a P3P, right? Which do you think you'll be flying more often? If anyone cares, my prediction, based on the Mavic Air: I think the Mavic Pro 2 is going to be everything the P4P is, maybe even with longer flight time (and of course it will fold), but they're going to leave out h.265 and variable aperture. Idk about P5P but I'd say 35 minute flight time and 4K60 will finally be h.265.
