I would imagine so. But how much more are you really getting with the SmallHD product that will change the way you operate (apart from tilting screen, which is not a function of the monitor itself)?

Seems remarkable what they have managed to squeeze in at this price point when you compare the price of accessories. 

I can actually see it outside in the daytime, and that is a HUGE advantage to having it. If you haven't used one, the difference between it and so many other monitors is great. If you have, then you know what I'm talking about. I hate that I paid that much for it, but there isn't a day that goes by that I regret the purchase. Oh, and I agree with regards to how much BM is able to squeeze in.

On (missing) AF, gimbals, speedboosters, hyperfocal distance and lens-choices. With Pocket "I" : the screen wasn't good, but it had the best peaking (Kryptonite-green). With shallow depth of field, no problem. sDoF, of course, was only possible with rather fast lenses, because crop factor was almost three. 

With a slow lens and with he said hyperfocal distance, almost the whole display became green. You wished you could reverse the peaking so that oof-areas were highlighted. Because of the size of the sensor (S16) but nonetheless relatively big pixels, it was sometimes hard to focus. 

Unfortunately, this hasn't changed. Yes, the sensor is bigger, the crop factor is just below two, but the pixels are smaller. And since hyperfocal distance works where the circle of confusion (that's us, the BMPCC fan group!) is smaller than the dimensions of the smallest picture elements, you only get HFD with very wide lenses with very narrow apertures.

HFD means absolute depth of field, fix-focus. I certainly like the idea, but not everybody will. For tripod and handheld shots (we definitely, absolutely need at least a basic rig-stabilization, never believe because it's comfortable to hold it will be okay!) we need to practice manual focussing (P4k display, if sufficient, if not with external monitor).

On a bright sunny day like today I'd strictly use HFD on a gimbal. Otherwise we'd need something like the Crane 2's follow focus and learn to operate that. This was something I dreamed about ever since I learned about steadicams. Have a big box of RC servos and miniature rig parts from my DIY efforts (originals were ridiculously expensive). 

Then again, with the existence of gimbals we stumbled into a trap. Do I really need to constantly move the camera in the Z-axis? No, I even don't consider these shots particularly cinematic any more. Whatever that means. It's time to revisit old threads on filmlook and adjust our understanding of it in 2018.

I’d like to see someone fly that on a gimbal. Or shoot discretely with it. The Veydras are fast; affordable; optically brilliant; compact; and built completely of metal. They have user changeable mounts for Sony, Fuji and micro four thirds. $8,000 for two lenses is out of reach for most of us.

To fly maybe not, that would be a really big drone :) but to install on gimbal, no problem, here is BMMSC with a 3kg + lens on a gimbal.

Of course, it depends on what you're doing. Brandon Li does the best gimbal work I've seen and often doesn't use AF at all.

Not true. He uses most of the time AF, especially when on gimbal.

the case of Brandon is more a proof that AF is amazing for video, than the contrary.

This crappy lens would actually be good for incognito shooting without a permit with the Pocket 4K. OIS and wide to telephoto in a pancake. Can be had cheap on ebay. 

To be inexpensive doesn't mean it is crappy... you know?

I've seen him comment on a 'making of' video somewhere where he specifically said he doesn't use AF, so I don't know what else to say.

I had a it for a while when I had a GH4. It's definitely crappy. 

I don't know that lens for such gross statement... But, for the goodness sake of it, can you point me any example where you may substantially testify that one?

To each focal length, glass behaves distinctly as usually happens. Different strokes for different folks is more the norm, isn't it? Or no colors in a plain B&W world, is that your shot? You know, I think we should all be eagering to hear from each other. Better facts than mere opinions though ;-)

Well it is objectively an extremely slow lens.  f/5.6 on the "long" end.  I can't think of any legendary f/3.5-5.6 lenses.  If you are looking for low light or shallow depth of field this isn't the lens for you.  And considering the in camera processing that Panasonic assumes with many of their lenses performance is sure to suffer on a Blackmagic camera that doesn't do that processing.

I have the cheaper longer version of that lens.  I only used it a couple of times before I bought a speedbooster and used my Canon 17-55mm f/2.8 IS.  I don't know about the version he linked to but reviews I've seen recommend using smaller apertures for consistent sharpness with heaps of praise at f/8 for my version.   So f/8 on m43.  Say bye to low light and shallow DOF.  I've hung onto my so I could theoretically use it as a walk around lens.  I guess I will do some landscape stuff with it with the BMPCC 4k while I figure out my lens strategy.

Having reliable AF-C is indispensible for gimbal work.

AF can cause many spoiled gimbal shots, even canon DPAF can mess up your shot at just the crucial moment.

You can pre focus and maintain subject distance and get great shots, even with shallow DOF. 

If you need more leeway, stop down a bit.

Yes, I also know "the cheaper longer version of that lens" aka usual Panasonic kit lens. No need to be legendary but also far to be crappy, as well : ) Low light and shallow DOF don't necessarily need to be photographic paramount either, even though shallow DOF is possible to achieve following the right instructions. Fast apertures obviously help but, it is not the only way to find it :-)
