Yeah looks like a great camera. I just bought the a7riii and I am debating whether to cancel the order...

Is a7R II in Super 35 Better than a6500 / a6300?
Don Kotlos replied to Mark Romero 2's topic in Cameras
I find the FF HD from A7rII much better than D750 as far as resolution goes. The Sony is almost as good as the oversampled image from A7sII in HD. 24/30 I haven't seen any difference but haven't used the 30p much. -
They are kind of a disappointment. They are just extended lenses that are going to be front heavy. It should be far better to get the Nikon/Canon mount with the Sigma adapter. Much easier to sell, and of course use on other cameras.

I would say an even better one without the lock for the PSMA dial Hopefully with a new sensor.

Yes, wider FOV makes the rolling shutter appear smaller for the same angular speed of the camera. -

Even if they are differences they should be fairly minimal. FF 1080p with A7rII in terms of resolution. Same A7rII is better. Additionally, with good light, you can use the FF 4K mode which has very good rolling shutter performance. Maybe A6500 is a tiny bit better? I am not sure. A6500 I think also adds sgammut3.cine which imo is the best space to work with. I am not sure there is a significant difference here either. It should be about an hour or recording for both. As far as PB test goes, the only thing that changed with the speedbooster was the angle of view, which made the rolling shutter appear smaller. But essentially it should be exactly the same as without the speedbooster. -
I didn't even know people PM like that. That is just sad.

Well, its announced. 4K, dual focus, but not at the same time. That's Canonizing for you. And if not enough, enjoy the 2.5 crop.
-
There are plenty of things that go in a camera so while these polls are fun, they shouldn't be used for generalizations. For example I don't mind about the resolution per se. I would be happy with 1080p if is coming from oversampling with no aliasing artifacts. Also dynamic range is less important once you go above 12 stops but the noise in each step might affect that. I would also place reduced rolling shutter quite high on the list. I have come to appreciate smooth auto iso as well. The list of course goes on and on and it is fairly subjective. So I could never reduce a camera to one spec.

Your mind was on the upcoming Tamron 28-70 f2.8 for Sony e mount. At least that's where my mind is ...

8bit → 10bit video with temporal noise filtering, stunning results
Don Kotlos replied to cantsin's topic in Cameras
@Attila BakosThis looks like a very good solution for banding. I had been trying just noise, but now I know that temporal noise reduction can clean it up nicely. -

Don Kotlos replied to cantsin's topic in Cameras
I dunno cantsin. I can't get past the codec limitations. For me, all this process doesn't really add anything. If you look at the hand there are terrible compression artifacts in both images, without any differences in color. Here is a comparison of few places with boosted saturation (top orig, bottom neat): I see mostly different compression. Here is the difference between the two frames: -
This sensor is not meant for consumer cameras. There is a large market for machine vision cameras that need the sensitivity of backlit CMOS sensors with no rolling shutter artifact at all. There have been many Sony CMOS sensors with global shutter. IMX249 & IMX174 are two examples that offer very good dynamic range ~75db as well. I have been using these for years now but with machine vision cameras. For consumers, there is no real need for an actual global shutter. A fast readout is more than enough. Even film has a rolling shutter, just a fast one ~5ms. And consumer digital cameras are already close to that. Take Sony A9 with its stacked sensor for example in stills mode, the readout time is ~6ms, and there is no perceivable artifact in most cases. The A7rIII in 1080p mode has 6ms. GH5s in C4K has about ~11ms. These are excellent numbers. I find anything above 20ms hard to use. For example on the other end of the spectrum, you have the jello 4K cameras such as Sony A6*** * A7s*, X-T2, NX1. http://www.dvxuser.com/V6/showthread.php?303559-Measuring-rolling-shutter-put-a-number-on-this-issue!

I don't know why they didn't also go for native c-mount: https://www.back-bone.ca/product/ribcage-rx0/

It is not about having extra batteries or not. It is how much time you get with each, for example, people routinely complain about battery performance of Sony cameras. The biggest problem is that Fuji had spent years and years arguing about the size advantage relative to FF, now they offer a camera that has almost the same crop as the top end m4/3, it is almost as big & heavy as the Sony FF equivalent with ~1/3 of the battery performance for video. Add the battery grip and now it is larger and heavier than a FF camera. Why do people always want to defend cameras until death? There are advantages & disadvantages with any camera. Let's be realistic about it so people can choose a bit wisely. Battery performance with X-H1 looks to be crap. No reason to argue against this.
-
But don't you still need to buy the 2 extra $70 batteries?
-
I think the advantages that X-H1 offers in video are 1. Fuji Eterna -> great all around colors with low enough contrast that require minimal work 2. Dual audio recording -> Omnidirectional + shotgun? Why haven't other companies done that already? 3. Expanded DR modes in video -> have to see how well this works but it sounds promising if the ISO performance is good enough. For people that want a hybrid and don't mind about FF, the X-H1 is a valid choice. The 15min clip limit and the ~35min recording time in 4K without spending ~$470 for the grip is just stupid. That makes it a $2370 large & heavy camera. I found this a bit more informative than others:
-
@EthanAlexander It is a hassle. For everyday projects, I don't want to have to change the range of all clips. Keep in mind that in most programs (if not all) the clips are not shown correctly so it is hard to preview the correct contrast/exposure of the clip before importing it into an editor.
-
Cine4 uses illegal values (0-255) and most programs do not recognize that correctly. Are you using the correct ranges? What color profile are you using? I have had a great experience with Cine/Pro modes with slight adjustments to the color depth. Also in the past, I had noticed differences in skin tones when contrast was adjusted between programs: By the way, like @Geoff CB I have also switched to Cine2 as well for most things
-
I was only comparing it to the zoom F1 or other compact recorders such as H1. If you don't need something this small or you don't want to go to F4 then I agree with you the Tascam is the best choice.
-
I found it much better than the Zooms but small it is not.
-
Unfortunately @Márcio Kabke Pinheiro you were right and I doubt we will ever see an updated GX8. Much worse EVF, no mic input, no HLG, scaled back IBIS...
-
An LX200 would also help with the sales.
-
I actually like it a lot. Smaller with tilt lcd. If they don't skim on the video part a lot and it has the IBIS from G9, it might be the first Panasonic I would probably buy.
