FS5: FS5 II rumored with global shutter

I'm a big supporter of these sites, but now it's just getting out of hand, haha.

Saying the same thing about the A7SIII...driving me nuts.

Does this include the Pro Football Talk too? 'Cos I can't. I just can't quit it. Not even in the off-season.

(as to global shutter on FS5II, that would require the F-55 sensor to be passed down the line).
 
whom really needs global shutter .. non of the "high end " Arri,s have it.. even a mechanical shutter is a rolling shutter.. F65 included .. its an anomaly that the F55 has it..
With the super fast refresh rates these days I,d rather have the higher ISO.. the non global shutter "flash" band is now audiance excepted .. you see it in big hollywood films.. apart from shooting F1.. or fashion runways.. who needs it.. ? let alone Fs5 users ..

Any VFX would welcome a global shutter. While most vfx tools and artists can deal with it rolling shutter is a camera artefact we can do without. If you've ever done 3D Tracking aka Matchmoving in preparation for 3D to be inserted into a scene you can see the errors in the scene dramatically increase when rolling shutter is involved. When the 3D element is inserted into the scene it has to be warped to match the original rolling shutter warping from the camera otherwise the scene will look odd. There only needs to be a few pixels drift before the audience notices.

In the CCD days we just had to worry about lens distortion which was kids play. So I know a lot of people who'd love global shutters or rolling shutters so fast that it's irrelevant.

Big agree. I 3D track a lot of of what I shoot.

Rolling shatter is not same on every cam, meaning the refresh rate is very different... for example Arri "almost has no" RS. here is one comparison:

Also here u can see a comparison of ursa 4.6k and canon c300 II at 22:08 ... and its clear how different it is. btw ursa has same 14ms RS as fs7 has

Arri Alexa Studio has hardware shutter that acts as a global shutter....

http://www.arri.com/camera/alexa/learn/alexa_family_faq/

"...The ALEXA Studio can be used in electronic shutter mode, in which case it functions like all other ALEXAs and like described above, but it can also be used in rotating mirror shutter mode, in which case a physical, half moon shaped mirror (see image) rotates in front of the sensor. This mirror shutter has the function of a global shutter. While the light strikes the sensor, the pixels are exposed and accumulate a charge. When the mirror fully covers the sensor, the charge is read out. This eliminates any rolling shutter artifact and works just like a film camera does in terms of exposure...."
 
Rotating mirror shutter is a rolling shutter though,has to be, its rotating..dont believe the sales dept ;0.. .. doubt anyone is doing big 3d effects shots on a Fs5..?
Not arrogant unless you have seen it in that way.. I think most fs5 users would want higher ISO.. as I had mentioned as one of the main reasons not to have it.. takes up sensor real estate.. obviously I wasn't including 5d,s in the statement .. I was referring to video camera,s.. good point re wedding dp,s .. but still think they would go for the ISO in dark churches they dont have a handy 18K HMI to light :).. as apposed to the flash banding ..that really no one cares about these days .. since people have seen them in $100m + movies.. (funny that that used t be a big deal even on small budget productions).. even doc,s..

Not sure how global shutter would be better for pop video,s..live concerts ? seems be plenty of them shot with RED,s/Arri/F5,s/Fs7,s etc.. must be actually 99% of all of them.. even the dreaded DSLR.. Ive used the F55 plenty of times and the slower ISO has always been a pain.. and zero advantage for 99% of shooting situations..except for some specialized situations.. effects/ racing cars ..

Would typical FS5 users prefer 3200 ISO or global shutter and a likely much lower ISO?

I think it's worth comparing two Sony cameras, the PMW-F5 and PMW-F55. Neither of these is to be confused with the PXW-FS5, the subject of this thread. These two cameras were announced in 2012.

These two cameras have the same sensor size and resolution, but one has rolling shutter, and the other has global. Their specifications say they have the same dynamic range: 14 stops. Furthermore, the base ISO differs by just 5/8 of a stop: ISO 1250 vs ISO 2000.

Unlike most of its competitors, Sony makes its own sensors, and I feel it is a step ahead of everyone else. In 2014 they announced a line of global shutter sensors, but for the industrial market, not their own videocameras. They said these sensors used analog memory to have global shutter. Now I don't know what analog memory is, but somehow Sony's sensors have 3.5 stops more dynamic range than their global-shutter competitors (see Sony Pregius Global Shutter CMOS Imaging Performance).

In 2015, Sony announced the next generation of those industrial sensors. They had 1/3 the pixel area yet 10% greater light sensitivity than the last model. Amazing. (IMX250LLR/LQR, IMX252LLR/LQR)
 
All sensor,s are analog .. no?.. and yes I know the difference between F55 and Fs5.. really wouldn't believe a lot of this sales stuff.. all Im saying is . who or why would 99% of the average users .. even of F55,s actually need global shutter.. as the refresh rate is so high now in most decent video camera,s .. better off to have the pixels and ISO.. eg just about every movie shot ,commercial, music video/corp etc etc..
