The 50-150 is parfocal and doesn't breath, it's essentially perfect. It's a steal at the current prices used. Did a shoot with it out on a beach handheld with AF on, incredible results.
Very interested in these Tamron's for their stabilization, rented the 35mm and the 85mm to test this weekend on my D750. Will report back with samples and impressions once they arrive today.

4K is the standard of 2016 and future proof.
Furthermore 4K is the only way to get true 1080p or 2K res out of a DSLR or mirrorless camera. None of the 1080p cameras shoot 1080p. It's just a sticker on the box. They are really shooting a pixel binned or line skipped image. The exception are the full sensor readout 1080p cameras like the A7S which down-sample better on the image processor, but shooting 4K is still preferable over this as it's future proof. In most situations you also have to shoot 4K to avoid severe moire & aliasing.
So in short, 4K was necessary to move us on from the crappy line-skipping and moire era of DSLR video.
It's not so much a resolution obsession, even if you deliver 1080p, it helps to have your acquisition quality 4K.
Now we have two kinds of 4K... that from a full sensor readout is preferable for the full lens circle to get used, whilst a crop of the sensor readout is a stop-gap until the sensor & image processor tech gets better - although sometimes it has its benefits - like a Super 35mm mode on a full frame camera, and 1.3x crop (1D C) doesn't hurt as much as a 2.3!
True, rolling shutter and heat issues can occasionally bite you on some of the lower end models, but it's still in the most part preferable to have some kind of technological progress than none. Without progress, we wouldn't get through this early phase of imperfect 4K and onto better things.
The only times I avoid 4K these days is if I am shooting hours and hours of live footage and need very small file sizes, or the other aspects of the image outweigh the benefits of the alternative 4K cameras for a particular project - such as full frame RAW on the 5D Mark III with magic lantern for the best colour and keying, or high frame rate 120fps 1080p which can be lovely for certain things.

It's just about sd-cards mostly. This bitrate is perfectly utilize nowadays sd-cards speed and works without errors or lags. I've tested now like ten 64 GB sd-cards wide variety of prices and vendors, they pretty much the same when it comes to speed of NX1 sd-card driver (? idk how it calls) and top bitrate which I can use is no more 190 for now, but I'm going to test further  
Sandisk Extreme Pro UHS I 95MB/s 64GB is fastest one that I've tested. I can use it with 190 mbps easily, it works fine, but to be sure I just fly with 180 mbps.
Strange thing, when I did first testing of bitrate hack, all of my cards goes with "card is too slow" message when I tried to record video, and first bitrate, that any card allowed me is 140-160 mbps. But IDK how, when after some shooting with 140-160 mbps bitrate I've put the same sd-card but with 180-190 mbps option, run record, it goes with same error after 3-4 secons video... and after that allows you to go with 180-190. After that it goes smooth and pretty fine with 190. Can't say the reason, I don't know it, but I can recommend this way to any testers - just go first with 200 mbps, wait for "card is too slow" message, go second time, go third, if message still appears, turn off the camera, set 190 mbps, run 1-2 record with error message, and maybe now you can do 190. If not - go to settings and decrease bitrate one step more, repeat previous step "with 1-2 errors"..
Second sweet spot of bitrates - is size of sd-card. Actually, this one works with "record limit" hack. This hack allows you to record more than 30 min video. For UHD@30 it's 76 minutes with sound and not limited without audio (one user on dpreview said that but I didn't test this yet). So, now you have 76 minutes limit, ok. And now we can set 120 mbps bitrate for UHD@30 and this is a truly sweet spot for this two hacks - now you can record like 74-75 minutes 120 mbps UHD@30 video without any fear to get the error message or crash without message at all (NX1 did this with 4K video that exceed time limit 76 min). It is very cool!
One page before I've posted the test results of my bitrate hack test. There is 4K video file that I create from two 4K footages one 80 and other 150 mbps. They just heavily destructed (only luma curve + brightness + contrast) for more visual reference, left side - 150 mbps source, right side - 80. Both recorded in UHD@30 with identical setting and environment, only difference is the bitrate. Scale to 300% for better proof and to eliminate influence of export bitrate. Can you see the difference between them? For me it's obvious, and this test - is how I actually open my eyes to see all the power of High Efficiency Video Codec implemented in H265. Highly recommend to learn about it, worth knowing. 
If by "motion cadence" cinematorgaphers means some sort of undescribed mixture of shutter speed, framerate and limits of modern encoding process, but from "artistic point of view", then I can tell, bitrate hack definitely improve this, yep. I'd say HEVC theoretically wins in this field when it comes to any lossy codec, and it improves greatily from bitrate hack. Overall quality of picture is improved, each frame is far more stable in terms of color, light - all this parameters, that goes to codec and being encoded, and this goes more smoothly, this also applies to the serial set of frames.

As for now and with latest update of Kino Seed's mod-pack I use SANDISK Extreme Pro SDXC 64GB Class 10 UHS-I U1 (95/90 Mb/s) for 250 mbps but you need to understand that bitrate actually recourse consuming option, and NX1 resourses are limited and other functions rely on them as well. So, with 250 mbps you can do very soft and slow footage without any complex scenes like smoke or fountains close-ups, fast moving objects or fast panning, So, if you intended to shoot, say, field and sky or interior from tripod without any fast pan or tilt - you be able to record like 1-2 good minutes of 250 mbps. I can manage like up to 4 minutes. And this is without sound, because with sound there is a problem with any bitrate more then 190-200, for now. With fast moving picture there is a problem - for encode this type of frame codec needs more resourses that NX1 can manage for this, so record drops with sd-card slow speed message. Presumable there is a memory problem involved and if I understand right - guys tried to manage this, but not yet and there is a big "maybe"
I think with latest script modifications and optimizations there is no big problem with any sdcard, maybe a little differences like 10 mbps so no big deal. You can use any sdcard with UHS-I or UHS-II specification

Thanks. 
I did a lot of movements in shot directly, but then for each shot I use speed ramps on FCPX. But the movements are real, from the camera, except for one or 2 zooming effects. 
It's all about playing with speed ramps at the right time during the right movement. 
No twixtor since I used 120fps and 60fps for slowmo
I took 600 clips during the 2 weeks.

Yeah man, I emailed because of your thread! 
Now we're on the Ballot!!!

Good work dude, 

Hi guys, 
I have been using the A7R II and the RX100 IV for travel in Cuba, check my video if you want to see the result. 
So far I loved the RX100 for the slowmo (I filmed everything in 120fps with it) and the A7R II was good too. The IBIS is not great but better than nothing especially when you dont have an IS lens. 
No overheating problem (this is mostly a problem for people who record long times). The biggest problem that made me sell it is ergonomics (body and menus, ..). It is atrocious. 
Also I am very disappointed with the AF. Actually my 2 biggest challenges during my trip for video were focus and ergonomics shits of the A7R. Having to set everything all the time was a pain, and the AF was not satisfying. I had no time for manual focus for the type of shots I did so missed a lot of shots because of this. I did focus manually 25% of the time though but it was a pain too. 
The only solution for me is DPAF from Canon or A6300 AF (I did not try it). 
Rolling shutter is insane on the A7R. 
I used the 60p FHD mode sometimes and also the FF mode instead of crop mode sometimes without noticing a big difference. 
I used a Pilotfly H1+ that was ok. Used it only for the RX100. 

The good thing is the combo RX100/gimbal 120fps and the A7R II for DoF shots and 4k.

Who has used this combo successfully? 
What do you think about the video? I feel horrible about how Vimeo destroyed it, the original file is SO clean on my screen... But I guess we are all in the same basket here.
 
 

Well, you can't share something that looks as nice as these and then NOT share the in-camera settings   Please, Ricardo, do share your latest settings?

Went to Porto on vacations this past week, what a wonderfull city ! Will be doing a video of it soon (trying to go for a watchtower of turkey feel). Anyway, I found a new 16-50S for 499€ and couldnt afford it, still bummed about it, but I might be able to get it, but its a shame I just got the 18-35mm...I dont really know what to do...
Also, tested some new in-cam settings, here are the graded results !













 
 

The GH4 hack will probably be the GH5. In fact, I think that was one of Panasonic's smartest moves... Listen to what the customers wanted based upon the popularity of the hacks. If Canon followed suit, the 5DIV should have 1080p Raw video. It probably won't though. 

4K can be challenging to edit on even higher end machines.  Since FCPX has seamless, built-in proxy support, your best approach is transcode to proxy on either import or afterward. This will yield a major editing speed improvement and doesn't cost anything. Procedure:
- Select clips in Event Browser 
- Right-click, select "transcode media", then pick "Create proxy media"
- In upper-right corner of viewer, click drop down triangle and select "Proxy". Do not select "optimized", since that will take up too much space in your specific situation.
- Before final export to a file, change viewer back to "optimized/original", else output will be in proxy resolution
In most cases editing H264 content (even 4K) is not extremely I/O bound due to the compressed nature. It is generally CPU bound and effects often use the GPU. However editing itself, rendering the timeline (minus effects) and exporting (ie encoding) to a file are typically CPU bound operations. So you want good I/O performance but if you are already bottlenecked on the CPU then infinitely fast I/O won't help. Using proxy media greatly reduces the CPU burden.
That said, it is good practice to have your media on a different drive than your boot drive. The HGST Touro S 7200 rpm USB 3 drive is quite good for a bus-powered drive but it's not equal to an AC-powered 3.5" external drive. You could move your media to the Touro drive and see if this helps. The 2012 MacBook Pros have USB 3.0 so at least you don't have the problem caused by slow USB 2.0 ports.

I use the 1/4 black pro mist to take the edge off sometimes. I like what it does for the highlights with rolloff and blooms. I got an 82mm one for 17.50 used  

Well, new Beta 12.5 doesn't have this problem with HEVC at all. It just doesn't support h.265 now

"Hello, Geoffrey,
I have tested with mp4 with h.265 video stream and an AAC audio stream both at 41KHz and 48KHz. It does not look like we will accept MPEG encoded audio in those formats, so it is possible that off your media has an MPEG, rather than AAC audio then there might be no audio heard in DaVinci Resolve for those clips.

Please let me know if you have any other questions regarding this matter.

Very disappointed in this, why would you say you support H265, and have to pay them a licensing fee to use the codec, then refuse footage from the one camera that shoots in it!

As Jim said, you can edit ProRes but not the DNG files.
However, I use "Raw Photo Processor 64" (its a free download) to convert the DNG files to 16-bit TIFF files. RPP has the best Highlight retrieval of anything that i've used, it has 4 different curve types (Film-like, L*, Gamma & Colorimetric Gamma), Custom or Auto White Balance (which is v.accurate), a load of TruePaper & TrueFilm simulations and so much more. Oh, did I mention that its free!
So no need for Resolve...

As a long time lurker watching the progress happen and trying out some of the hacks my self here is a brief summary of main accomplishments.
Current hack achievements in no particular order
Increased bitrate on both NX1/NX500. So far there is no consensus on the optimal bitrate. Further testing is required by experience videographers who are good at analyzing footage. Added 2.5k full sensor readout with increased bitrate on NX500. I do not own an NX500 so I am not sure what is really happening with this hack. Perhaps someone else could fill in. Removed video record time limit on both NX1/NX500. This is something I haven’t personally tested as I do not need it but reports sound like it works perfectly fine and can be used to record videos that will fill up your card. Fully electronic (silent) shutter on the NX500. Not yet working on NX1 from what I understand. There are currently three main ways to apply hacks to the NX1/NX500. The original method by running in factory mode by running a script on the SD card root called info.tg that can run other apps such as Otto K’s keyscan The WiFi method. Similar to the blue tooth method below but more risky. The best method is the blue tooth method. This is done by modifying the file /usr/sbin/bluethd in camera to execute a scripts that can run whatever other program you want. Telnet (busy Box) can be run from the SD Card to remotely execute any command on camera.  Alot of the built in camera commands have been figured out and you can now write scripts to make the camera do pretty much anything you want. Even I was able to written a few scripts .  
Current progress
Lately (past few weeks) the majority of the activity has been around trying to remove the in camera NR for video. There has also been quite a bit of talk about creating a GUI for all the hacks. If you are a programmer and are interested in getting involved I think this is likely the area where you could really help out.
  If there is anything I got wrong or missed please don’t be shy and call me out on it

regarding the sharpness: i'm starting to believe -10 = no post sharpening, like someone else suggested. i did some tests with many details and sharpening -10. i couldn't find any interpolated edge sharpening, which is usually visible by ringing artifacts. my consumption: the oversharpening some are seeing is a result of a downsampler, probably bicubic ... is there a way to change this? i don't know.

Apply my NX1 LOG LUT first as the input LUT then the DELUT as output LUT.
http://www.eoshd.com/samsung-nx1-video-settings-guide-tutorial/

I would like to see this hooked up to a Leica SL, which can actually output 4k 10-bit. 

Really nicely put together. Can I ask, how do you achieve such transitions?

Time to make this topic alive again, comon people, lets get sharing !
 
 

Would be interesting to see (or hear...) if the preamps are really capable. Saying that it´s just better than "most of DSLR preamps" is not very promising, though...
