Hi, all! I just got my new 1DX Mark II, and I would like to use a cage with it for video shoots where I'm attaching a monitor, audio recorder and wireless receivers to it. Any recommendations?
Ideally, it would keep the camera from twisting for use with follow focus units. Also, I'm looking for inexpensive if at all possible (I already spent a bunch on the camera itself!)
Thanks!

Hello, gang! I just got a 1DX Mk II and I need some CFast cards for it. Does anyone know if these will work for shooting 4K 24p on the 1DXII?
They're significantly cheaper than the faster cards, but I need to know if they'll work for 24p (I assume they won't work for 60p).
Thanks!

After seeing the DPAF of the Canon 1DX Mark II in action, I find myself seriously considering switching from my beloved GH4. If Panasonic can add a similar Autofocus to the GH5, it might keep me interested. Otherwise, I think I may need to go over to
the dark sideCanon. Which is a shame, because I have a bunch of m4/3 lenses that I love. But for my line of work (event video) the DPAF is too hard to pass up. -

Here is a really impressive demonstration of shadow recovery on the 1DX II (video and blog by Jon Roemer):
I can start to see how Cinema5d got similar overall DR numbers in its testing of the 1DC and 1DX II. If you expose for the highlights, you have a lot to work with in the shadows and midtones before hitting visible noise levels.
Wow... This is fantastic.

What's going on in the first video though? Looks like some really strange jello effect (post production stablisation, maybe?)
Holy warp stabilizer, Batman!

This is my wishlist for the GH5:
- Dual-Pixel Autofocus with face tracking
- IBIS
- 10bit 4:2:2 internal
- Multi-aspect ratio sensor
- Full size HDMI with no lag
- 4K 60p
- ISO 3200 as clean as current ISO 800
- Better implementation of V-Log that uses all the bits properly
If they give us internal 5K or 6K then even better, but I'm happy with 4K for now. The Dual Pixel AF of the 1DX Mark II is seriously tempting me to go over to the
darkcanon side... -
Another question... How easy is it to match a 1DXII (shooting in HD) with a C100?
Also, if using the Atomos Ninja or Blackmagic Video Assist with the 1DXII in HD I can bypass the 30 minute record limit of the camera, right?
-
Quick question... Does the DPAF on the 1DX Mk II work with lenses from other manufacturers (Sigma, Tokina, etc.) or is it just for Canon lenses?

Yes of course. Any Canon autofocus lens, not just USM.
Excellent, thanks. And what about non-Canon lenses? Sigma Art, etc. Would the DPAF work with those?

The difference in the sound is stark, STM lenses are dead quiet, ghost-quiet, no sound at all while operation, while USM lenses Roar in pride! The speed in stills AF the USM motor is stronger and makes powerful pushes, gets fast AF. While STM motors are physically weaker in built, and acquire final stills AF slower, all things being equal.
There's something worthy of notion: there are no STM lenses for the 1DXII, (all of them are APS-C/S35 - so won't cover the 1.3x in most cases)Except for the Canon EF 24-105mm STM IS, a variable aperture lens (not the f/4 L). (Which does send a message that Canon will release later STM FF lens)
However using the USM and all Canon lenses DPAF works 100% smoothly. Just any on-camera microphone will pick-up sound, real good ugly roaring sound...
Just to be clear... I can use any Canon USM lens on the 1DXII and use DPAF face tracking while shooting 4K video?

I actually think 6K would be great on the GH5. It lets me downsample to 4K with improved color, much like it's good to downsample 4K to 1080 on the GH4 now. Nobody is going to be displaying 6K content anytime soon, but downsampling for pristine 4K is very attractive to me. It lessens the appearance of noise and compression artifacts in the image and improves the color sampling. What's not to like?

At ISO 800 a GH4 pixel can hold 5091 electrons and has a read noise of 3.1 electrons. That means the noise in the light will exceed the read noise once you get to about 17 electrons (it's 56% efficient converting photons to electrons and the noise in light is the square root of the number of photons). So anytime the pixel is much more than 3.3% illuminated the sensor read noise isn't that big a thing. For example at 10% illumination (509 electrons) you have on average 17 electrons of noise and the rest is signal. Even if you go from 3.1 electrons of read noise to 0.5 it isn't making a significant difference (btw noise combines as less than straight addition).
So... are you saying a GH5 with a Micro 4/3 sensor can't have better ISO performance than a GH4?

See, now THAT's a good idea. Everyone and their mother already has a FF or S35 camera in their lineup... except Panasonic. If they introduce a medium format camera and lens lineup then they have the best of both worlds: Micro 4/3 for the masses and Medium Format for the fashion and commercial crowds. Why compete against Canon, Nikon & Sony?

I can't see you getting ISO 3200 as good as the GH4's 800 unless it's by more noise reduction, as it's a sensor area issue, most of the noise coming in with the light rather than being due to the sensor. I don't know if you'll get 10-bit but it's a definite maybe. I think the rest looks likely. I'd also like FHD modes that don't skip 30% of the pixels, so the aliasing/moire goes away. I suspect they will try to be close to the Ultra HD Blu-ray spec, including gamut.
Sensor size is not the only factor that determines noise in the image. The GH4 has a smaller sensor than the GH2, yet it has better performance at the same ISO. ISO 3200 is only 2 stops higher sensitivity than ISO 800. I don't think it's unreasonable to expect better ISO performance from the GH5 using a Micro 4/3 sensor.
Also, I forgot to add to my list that I want the GH5 should have 5-axis in-built image stabilizer, as long as the camera doesn't overheat like the Sony cameras. I need to be able to shoot continuous footage (not limited to 30 minutes) so if IBIS causes short record times then no thanks.

No, no, no. I don't want a Super 35 sensor in a GH5. I REALY LIKE the Micro 4/3 size sensor. It makes focusing easier than S35, yet still has enough shallow depth of field to look cinematic. I don't care for Speedboosters. I love using my Voigtlander and Lumix lenses on my GH4, and would want the GH5 to shoot on a 5K or 6K m4/3 sensor downsampled to 4K in camera. 10-bit 4:2:2 internal 4K would be an incredible way for the GH5 to separate itself from everything else in the market.
I don't want to use S35 or FF lenses. I WANT my lenses to remain small. I want my whole kit to remain small. There are tons of other cameras out there right now that use S35 or FF sensors. I don't want to pay for a large sensor if I'm just going to use a 4K crop from it because of all my m4/3 lenses. If you want S35 or FF, buy a different camera. Get the Sony A6300 or something else. Leave the GH series Micro 4/3 sensor, because there are a lot of us that find it the perfect size sensor.
What I want in a GH5 (in order of importance to me):
- Micro 4/3 sensor
- Internal 10-bit 4:2:2 4K
- ISO 3200 as good as the current ISO 800 of the GH4
- 4K 60p
- No lag on the HDMI output
- V-Log included
- Keep the same style body & battery so all GH4 accessories work

Any thoughts on this ISCO Micro 2X for use with the GH4? http://www.ebay.com/itm/Isco-Micro-2X-Anamorphic-Lens-for-DSLR-EXTREMELY-Sharp-close-focusing-light-/181444226398?pt=LH_DefaultDomain_0&hash=item2a3eeb2d5e
Which taking lens would work best with this one?

The more I think about the DVX200, the more I like it. I shoot live theatrical events (concerts, musicals, plays) and my life would be much easier if my camera had the image quality of the GH4 but with a great servo zoom lens, ND filters and XLR inputs with proper controls. Imagine that, a GH4 with the usability of my old DVX100! Assuming the reviews and footage are good, once it comes out this fall I'm probably going to get one or two of these for my business. I'm tired of dealing with still photo lenses to shoot video. I'm tired of dealing with clunky XLR adapters. I'm tired of dealing with a camera that isn't designed for video first. The DVX200 solves all of my problems in one camera.
I do wish Panasonic had ALSO introduced an AF-200 with the same specs except a m4/3 mount. But for my needs, the DVX200 is exactly what I need. I just didn't know it until they presented it!
-
I'm beginning to warm up to the DVX200. I just hope it's good in low light. If it's significantly better than the GH4 at ISO 1600 I might just get this for event shooting (which is most of what I normally shoot).
-
I'd love the idea of both an AF-200 and a GH4x: Both with the same image quality & firmware features, but the AF200 in a large body with all the requisite outputs, ND filters buttons & knobs and XLR inputs, and the GH4x with the same body as the GH4 but the same image quality for those of us that need small camera bodies.

Currently it's due April / May.
Nice. Any word on price? And which lenses do you recommend for use with the adapter and a GH4 in 4K 4:3 mode?
-
I'm very, very interested in this 2x anamorphic adapter for use with my GH4. Now, if only the GH4 could record in 24p when in 4:3 4K Photo mode...
Would the SLR Magic 25mm f/0.95 be a good match for the Anamorphot?

Bah. No 24p at all? That instantly makes me not be able to buy it. So sad...

Right now we only have the Canon 1DC for $12000 and soon the Blackmagic Production camera for $4000, in addition to the RED cameras.
Just curious how long you think we'll have to wait until DSLRs or mirrorless cameras can shoot 4K / UHD footage for around $2000. Three years? Two? One? I'm betting sometime in 2014. What do you think?

Thank you for this article (and lovely short film). All you really need is a camera, a lens, a recording medium, and a dream.
What cage for the 1DX Mk. II?

Nice find! So I just replace the rod on the side with a longer one to fit the 1DX Mark II? If so, that's a hell of a deal!
