4k Video Testing

The SL catalogue says, on page 16:

 

'Another useful aid is subject tracking. Here, when a particular object is marked with a focusing point, the focus is held on this object and follows its movement.'

 

The cinema5d review says a weakness of the SL is:

 

No continuous autofocus.

 

Does this mean the continuous autofocus that works with stills does not work with video? Not a huge problem - I'd want to be able to turn continuous autofocus off if it did work, but it would be handy at times.

 

Thanks.

I agree, inability to assign a LUT for viewing L-Log is annoying. As you mentioned, I use a Sony Log2 LUT on BlackMagic Video Assist 4K, and it provides decent picture, good enough to judge focus, exposure and WB visually.

 

I am not sure if full-frame 4K is at all possible, as the hardware may not be powerful enough for it. Certainly now, when Sony a99-II can do it, we all suddenly decided that Super35 is not cool :) On the bright side, however, T lenses can be used for 4K. I've been pleasantly surprised with image quality given the size and price.

Irakly, you're apparently putting some time into this.  Any results to share yet, that show what is working for you in grading?.  I've been shooting short clips using the LUTs that come with FCP-X, and can do about equally well with my own color grading.  David Farkas tells me that he touches things up after using the Arri LUT in DaVinci or perhaps it was Premiere.  Since I want to go entirely handheld and use internal recording to the chip for some sports projects, I am just as concerned about steadiness as color at this point.  I've concluded, though, that a preamp and good microphone are pretty vital.

 

Just as a grading exercise,  here is a short clip shot in L-Log and hand-graded.

And I can't see a need to use more than the Super 35 area and the 8 MPixel found there at the moment.

Here, a couple of videos. Both graded in DaVinci Resolve Studio. Never mind the subject matter :)

If by "entirely handheld" you really mean entirely handheld, I would not really do that, especially with sports. You need at least a cage with some sort of a steadying device. Image stabilization, both internal and in P&P can do just so much.
