  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Sony A7r II - 4K internal want this!!

And ... If you ask politely, I am sure they would be willing to show you their gold jewelry box filled with powdered rhino horn.
 
I got my sony a7rii today and a 28-135 lens to keep it company. Hope it will be good enough as b-cam for the epic, but i think they will cut nice. Will be great to have a small camera that is easy to bring with you.
 
What nd filter are you recomending for the 28-135? Any small kit. Would be happy to start with something like 0.6 0.9 and a 1.2
 
The 4k-in-pocket-part is really tempting, but i was hoping for more improvements and better performance in regards of stills, because that is where my priorities are. It looks like a few things got a bit exaggerated, like the AF-thing with Canon-lenses. It's better than ever but can not replace a Canon.So, i'm not going to switch from Canon to Sony yet. I will buy a 5DsR for stills and look again at Sony, when they're releasing the A7SII or maybe that 8k-thing, if rumours are true. ;)

I have that lens and I use a cavision 95-82 step down ring for 82mm filters, just because you can find much better filters at that particular size.
Like the Kenko NDX variable filter (the only variable ND that I know of that has a depolarizing element to get back natural looking skin) which I also love.
That combination affords you a good 2 regular or 3 thin filters before it starts vignetting at 28mm full frame.
Also remember to buy a cap for it. ;)
It's not perfect, but very nice.
YMMV.

How is that? Depolarizing?

From their website:

http://www.kenkoglobal.com/photo/filters/nd/variable_ndx.html

"...The Variable NDX filter changes the brightness of light using a polarized filter. This new filter uses a “polarizing effect cancellation” where a polarized filter is used, but purely for controlling the amount of light with no effect on color balance, glare or reflections...."
"...Random polarization is eliminated when natural light passes through the depolarization plate, minimizing any change in color by using 2 layers of polarizing film..."

I absolutely hate variable ND filters. Sure, they are convenient, until you sit down to watch your dailies and find them full of weird artifacts that aren't supposed to be there.
This one is a lot more predictable. It's not perfect nor cheap, but it sure is 100 better than any other variND. :)
 
I don't understand how it is possible to depolarize any polarized light without introducing some blur or fog effect.
Any one has a better understanding of this porcess?
 
Experimenting with a variable ND and I'm not impressed either. Footage/stills foggy. Not a fan.

I don't really know much about the science behind it.

What I can tell you is how it behaves in use.

In my experience, it eliminates the most common artifacts such as tinted/supressed highlights, waxy looking skin and reduced reflections.
All of the above look exactly the same at any set density for the filter regardless of the rotation angle of the filter to the lens.
I've seen few instances where something weird happens, such as some car windows developing weird patterns, but it might have more to do with the car window manufacturing process itself.
Before trying out the Kenko NDX I had a Tiffen Variable ND that I hated so much, I just ended up giving it away for free.
After the Tiffen I swore I would never be suckered into the flawed idea of the Variable ND filter again.
And a few years later I read about the Kenko and it made me curious.
In my opinion it's the only filter I would ever use in place of regular ND's

YMMV. :)

PS. It doesn't even darken LCD displays.

What Variable ND's are you guys using?

I use a cheap Chinese K&F Concept Variable ND and don't have any issues... http://www.ebay.com/itm/200993668719?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
These were all shot in 6K 6:5 ANA mode at 82fps 9:1 compression. These are all out of camera Dragoncolor/Redgamma 4 with no corrections:

When Nick Fury first got his Kowa Anamorphics we tested the different Variable ND's to see if we had any negative issues, added flares, or loss of resolution. We tested the K&F cheap Chinese VariND, a Tiffen Vari ND, and the Firecrest ND's. The Firecrest ND's were the best color wise, but with a white balance tweak to the vari ND filters they were identical. No softening or added flares from the Vari ND's. So I shot the entire above shoot with the cheap Chinese Vari ND and had no issues. Couldn't have done it without one as I was operating and pulling my own focus.

The patterning in windows is from the manufacturers tinting process. I can see it clearly with my polarized sunglasses on any car. It's not an artifact of a Variable ND alone.

Why not? The A7RII sensor is 42MP . . . 7952 x 5304 pixels. Seems like that covers 8K HD (7680×4320) with some pixies to spare

No, because it will be using the sensor in the A7R II. That is still not as good as the A7s which remains king of low light. It's still decent in lowlight and has been shown to do fairly well at 6400ISO. So maybe with better processing and some in body NR, they could possibly get it cleaner in a digital cinema housing vs. the small mirrorless A7R II.
