A7rII has 120fps albeit at 720p, but it's there...and in full frame mode.

Currently I doubt Sony can make SD cards record 4K RAW with a new firmware. 

A 4K DNG frame without debayering is ~13MB.

24frames/sec x 13MB = 288MB/sec 

Currently the fastest minimum write speed of SD cards is U3 (30MB/sec).

So you would need around ~10:1 compression which would need a fairly specialized chip that I doubt FS5 has. 

A bit confused on this... please chime in!

So we want to shoot in S-Log on, say, any of the 4K entry level cameras (A7Sii, Rii, FS5) to get that flat profile and wide DR.  But I keep running into claims that unless you're shooting at the native ISO (1,600 for A7Sii/Rii bodies, 3,200 for FS5) you aren't getting all that DR.  I just watched Allister Chapman's presentation on FS5 and he clearly states that you ONLY want to shoot in S-Log at the native ISO of 3,200, otherwise you're just wasting space because you are NOT getting that 14 stops of DR with any other ISO.  I think I've read his comments on this as well in his A7s exposure guide too (edit: yep, just re-read it and he states the same there)

So, what's the story here?  I see everyone shooting S-Log in whatever ISO they want, but is it somewhat of a waste?  Since the floor is already so high at 3,200, the only way to control your exposure is to use NDs and to stop down (neither of which is all that desirable, especially stopping down).  But, bigger question for me is with A7Sii in low light... since I can't open any wider than my glass allows, what happened to DR when I start cranking up the ISO, to 6,400, 12,800+ while shooting S-Log?  Is my DR reduced to the point where it makes no sense to shoot S-Log?  If yes, then what are the benefits of shooting S-Log then... color grading from a flat profile?

And probably an even more important question is... since you want to overexpose (2-3 stops) while shooting in S-Log, unless you're shooting at the native ISO (the only place where you actually getting the full 14 stops of DR) you really HAVE TO shoot at native ISO, otherwise, you'd be overexposing and not have that DR to work with in post.

I'm still learning, so excuse the ignorance if these are "duhh" type questions!

Where can I find this?

thanks

Thats no problem, since the NX1 has that covered, and would still be my main camera.

I love the full frame aesthetic in Video, so matching it with the NX1 would be killer setup.

Beautiful footage Stab!!! Thing is, I want something that can be with me at all times (that can be kind of portable with a pancake). Can any of the smaller panasonics match the GH3/GH4?

Yeah, size is important. I'm leaning towards the A6000 because of the EVF (and very excited to hear about the A6100/7000/whatever they'll call it). Can anyone who owns one comment on it's "pocketablity" with a pancake?

 Thing that makes me less excited about the sony's is the lens family, but no system is perfect so...

How about the FF/S35 shortcut issue?  

Anyone got any thoughts on the samyang 14mm cine on a GH3 thus getting a 28mm equivalent?

Nikon has filed patents for a mirrorless lens for a camera with APS-C-sized sensor.

Not all of Nikon's lens patents get used in the end, so take it with a grain of salt. However, considering Sony's success with smaller mirrorless camera bodies suitable for photo & video and the current maturity of EVF's, I think Nikon is likely to be interested in getting into that market.

Oh awesome, Might look into Nikon mounts

Seems strange to rate a lens because of it's body's megapixels, thought a lens comparison site would have had more equal tests but i guess things change as the years go by.

Thanks i kinda thought that the lower score on the charts meant that something was wrong with the lens on certain mounts you see. Much appreciated.

it's unfortunate no one has made a focal reducer for the nx1 yet!  vintage olympus pen F lenses would be a very good match if you can ut together some type of cannibalised adaptor.

Hello There guys i have a simple but important question to ask.

Let's say i wanna buy a samyang 85mm t1.5, is it worth buying a E Mount base straight for my A7RII or an EF mount base than adapt that with the adapter.

Iv'e seen that some lenses have a lower scores because of there mount (nikon,sony,canon) is this because when a lens is adapted from EF to E or the other way around, it get's reduced sharpness because it simply works better on EF fit.

Curious if it's just best to keep the EF fit then adapt it to sony to guarantee the best optical performance? Or just buy an E mount glass to fit with no adapter?. Sound stupid i know but is this a known problem with 3rd party lenses? Sigma,Samyang,Tamron etc etc.

It did really annoy me in the summer...

The sunny weather mode however boosts contrast so much, it would make accurately shooting / exposing in S-LOG very tricky for a start.

The EVF in sunny weather is the way to go, ignore the LCD.

But even then the EVF is less than stella - goes invisible when you have direct sunlight coming at the camera sideways.

This video is a pure goldmine of information regarding the proper use of Sony cameras and their features, but most of this can also apply to any other camera brand. I bow to the man for this kind of simple but thorough explanation of all the features, codecs, gamma curves, gamuts etc., when and how to use them, why not to use some of them in some scenarios...

I highly recommend watching this whole video, because even if some of you guys are already familiar with most of this stuff, I'm almost certain that you will get some new useful info.

A stills body primarily targeted at video is a niche product. Not hybrid--that's common now--but primarily meant for video, with decent stills as a side bonus. Great for guys like us, but it leaves most stills shooters scratching their heads. 

Not to mention Sony's lossy RAW, abysmal battery life, and lack of tilt/shift lenses (adapted lenses are an option, but suffer from planarity issues that kill sharpness on such a pixel-dense sensor).

Does this not make you ask yourself some questions about why they are still top of the stills game?

Is it because their DR holds well over the entire ISO range, where the Sony (Nikon) chips have a great native DR, then crash and burn away from that native ISO.

I'm no tech head.... But it seems Canon are doing something right, with stills at least.
