Is the rolling shutter faster?

I doubt slog3 is going to be better than slog2. If anything it will make it worse for skin colors since there are even less values assigned in mid gray level. Increasing the dynamic range with 8 bits is just not good for skin colors. I wish they had included 10 bits. But that might have been impossible with the current thermal envelope of these cameras. Now, the only difference between this and A7rII for my use is the better high ISO sensitivity. Maybe the overheating too since I doubt they released a video centric camera with overheating problems.

You are right in a way. They can never achieve the same quality as with a stabilized camera. The reason is that there are perspective artifacts that cannot be accounted for (no depth information) and even if they were it would require a very fancy image synthesis algorithms and again it wouldn't look as good. This method works by actually measuring the motion directly instead of inferring it from the data. So crisp images are not necessary for that. What they do need is images with very very little motion blur, cause the motion blur will have artifacts from both camera motion and rolling shutter, but it is nearly impossible to compensate. As you see in their site, they have just one cross for that exact reason. This is a great solution for wide angle shots, with most objects in far distance. You would not be able to create such a good footage with a normal/zoom lens and close focus. But I guess how many people run like that? Its a great product, but for a limited use and I think they don't make that clear in their kickstarter page. The truth is that if you do any action shots like the ones that they show, then yes it will most definitely work great.

I wonder how it will work with cameras that have IBIS.

"Unfortunately, the smudging of the color takes place quite early in the pipeline because it is evident in the Odyssey recordings as well. The h.265 compression has little effect on color detail - it just adds some extra blocky compression artefacts." http://www.migueldeolaso.com/press/2015/5/24/samsung-nx1-4k-mirrorless-camera-test

What he meant is that you can create the LUT in Lightroom (or photoshop too) that gives you the look that you want, and then use that LUT in Premiere instead of the built in color grading.

There were a lot of people that asked the same. So now Premiere CC 2015 has the lumetri color panel that provides very similar experience to grading in Lightroom.

The crop factor is irrelevant. Think about it: Take an image that is projected on the full sensor. Now you move the camera by x amount. How much the image moves on the sensor depends on the focal length of the lens. Crop it now as much as you want. The physical movement of the camera is the same, the image projected on the full sensor has moved the same as before, so the compensation by the IBIS should be the same.

Always set the actual focal length of the lens. So for a 50mm set it to 50mm. The sensor movement is independent of the crop and only depends on the focal length.

It is one thing to support a codec, and another to provide a smooth editing experience. Hopefully with the proper hardware support transcoding will not be necessary.

I agree that methods like these are not good, but it was crapware that was intended to help the stability of the computer for novices. Thats why these were a problem with only the non-thinkpad series. Definetly not malware. Also Lenovo learned and stoped puting it in new computers. Emanuel is right, fear is a bitch. Here's a hint to you - misinformation does not help.

Thanks for the input. I am not sure how much the hot shoe can withstand, maybe the did in on purpose so it does not damage the hot shoe. And that being said, it might be the reason that it didn't inherit the tiny handle from the XLR-K1M (which I would really like if it had..)

Crop mode is better. The Chris has posted some examples in another thread: http://www.eoshd.com/comments/topic/9027-sony-a7r-ii-official-user-thread/?page=9

Just tried warp stabilization on Premiere. Just for the motion analysis it takes about 30' for a less than 2' 4k clip. That is with a 8 core overclocked to 4.5Ghz machine! Not that cores matter since it is not a multi threaded computation. Now I agree with your point. I cannot imagine myself having to stabilize longer 4K footage.

Yeah, I know. My point was "Relax we were just comparing some numbers and not the cameras as a whole package" Nope. Never did that. It could very well be the case, I never claimed otherwise. But if you have evidence of this I am sure a lot of people would be interested to see it. Well now its getting silly. Enough with this gearheaded fights.

Again, A7RII during HD recording does not overheat. Where did I say that someone should buy the A7rII over the D810? Buy whatever works for you best. I am pretty sure each one has its own needs/wants. Keep in mind that DXO compares just sensors and digital processing. Cameras are much more than that. Please look again and you will see that the whole conversation was just on numbers...

I am not that sure. Personally the 4K is much more overrated than having stabilized recording. Of course I value high quality HD and definitely Olympus can work on that, but the type of shots that you can get with such a small package is very very very useful. At least to me. If you see the type of setups they had to stabilize their cameras (huge cameras by the way) and how shaky the footage can look on handheld small cameras like BMPCC you can also imaging how useful a proper IBIS system is.

You keep mentioning the overheating but I have never seen any A7rII camera overheat during HD recording. I have no doubt that D810 is a great camera and quite likely the colors will look better out of the box when compared to the A7rII, but what's your point?

The point was made specifically for the DR during video, and the A7rII can record for hours HD footage without melting like the D810.

Great picture! Since A7rII has the same DR as D5500 (and better color sensitivity) you will be able to capture the same quality of photos. Oh come on. Look at my previous comment. For less than 1% of the users. For the other 99% the much better DR in high ISO and video will be more useful. You must have found the only point in the whole review that the A7rII performs very good and not great On that note, DXO does not test long exposures, where the DR of A7RII appears to suffer the most.

In that case they will be pissing away on a big opportunity. In the worst case I hope they somehow improve the 1080p quality.

Yep thats the reason for using the Tiffen UC3... Also outdoors a variable ND of questionable quality makes it even better since both act like low pass filters that take care of the aliasing.

There was no point at which I was confused as to which is which. The difference was so dramatic that I had to double check the A7rII had the IBIS on and at the correct focal length. That is why I didn't even think of labeling the footage. The flare is because of the filter that is used with the E-M1. I guess it was only clear to the ones that have used the Olympus IBIS before... I also didn't want to comment on the huge difference between the two so I wouldn't start a fight. All I can say is that I can't wait for the E-M1II to have 4K.

It didn't even cross my mind to label the video. I said that it was late in the night... But yeah left is E-M1 right is A7rII.
