F65: F65 - Ask me anything

I have not done any empirical tests of the F65 but I would say its electronic shutter is "as good/bad" as the Alexa or Epic's. With the mechanical shutter going, it does what it is supposed to and renders a pretty stable image. It should be more filmlike than the F35's motion, as the F35 captures a frame globally and simultaneously (not something even film does).

The F55 has a global shutter - similar to the F35's, although not achieved the same way.

Does the F65 24f motion blur look more like film compared to the FS700 RAW , F5 , F55 cameras? Whats the science behind it?
https://www.youtube.com/watch?v=hnqANUgzzGw heres a video showing the f55 rolling shutter to be better than that of the ALEXA.

Thanks,

Take dramamine before watching that video.

The last time I felt like that was after a night of HEAVY drinking when I was about 22. Slept with one foot on the floor...
 
James, I understand Ex Machina used anamorphics with the F65, so I'm assuming there's an anamorphic mode? Have you used it and do you know how the image area compares to Alexa 4:3 and Ana Epic Dragon?

the camera supports both 1.3x and 2x anamorphics. Like any digital camera it crops the middle of the sensor though. Personally I would only want to use anamorphics on something with a 4x3 sensor. The Dragon is probably slightly better as it has a larger chip although that presents its own set of issue with spherical lenses.

apparently Sony did not want to include a 2x anamorphic mode, but it was requested so they did.
 
The F65 will do up to 60fps in full "8K" raw, and the HD modes.

60 - 120fps are only achievable in F65RAW-HFR mode. I don't know exactly what that does, but the sensor resolution is halved. Although, it is only halved to the same resolution as most "4K" cameras. It does not crop the sensor, so I must assuming it is line skipping.

In order to avoid moire issues with doing this, the camera deploys a specially designed OLPF in front of the sensor when shooting in this mode. This is why you can't use the ND wheel in HFR.

I believe this restriction was pretty much due to limitations on data rate rather than a sensor issue. The mechanical shutter also does not work above 60fps, however I tend to find stuff shot above 60fps I am normally fairly still anyway.

Hope that helps!

Technically it has to be more "film-like" because it uses a physical shutter. But like with the D21 it just doesn't move as nice as the F35. I much prefer the motion of the F35 to the F65 or F55 and Blackmagic global shutter for that matter. I believe the CCD plays a big role in that too. Whatever it is the F35 produces the best motion in the business in my opinion.

I never saw too much sense in an anamorphic mode with a 16:9 sensor. You basically lose the whole point of anamorphic.

I agree. That hasn't stopped it becoming a buzzword. I would like to thing if I shoot anamorphic, it would be on film.

Even ARRI themselves said there are no technical reasons to shoot anamorphic now, it is purely stylistic.
 
My "lightweight" setup.

In the next month I am going to try and pop to a local racetrack and get some footage of some cars or bikes or something, to share with you lovely people. So that we can have a little pool of 4K footage that has absolutely no rights or clearance issues whatsoever.
 
Couple of pics taken on that setup, wide open. 800 ISO. Dark and difficult subject. I look forward to getting the lens outdoors in the near future.

First shot graded a lot more heavily than the second

Here are a couple more shots from the short I did this month. Kind thanks to our stills guy Samuel Dore.

This shows the camera in handheld setup, hopefully illustrates it a little better for those curious about handheld on the 65.

Look's like the same load as an old Sony D600 or 790 with a wide angle and a Hytron 140, with a wireless hop, good for a 5-7 hours before the the nerves get crunched! I hope those producers treat you well.

I think that test is a little bit suspect. I don't trust any test where they manage to lose a whole batch of rushes!

Of note when shooting in Tungsten mode the F65 actually uses gain to help even out the colours, even in raw.

Well, I wouldn't throw out the baby with the bathwater.

The DIT may have pulled a boneheaded move, but Geoff Boyle and the rest of the CML gang have probably forgotten more about cinematography than most people know.
 
It is a great annoyance however as the ALEXA clearly performed better under daylight (as do nearly all digital cameras), so those were the last rushes to lose.

I don't find dynamic range under tungsten a great issue as that generally means I was in a controlled light situation anyway.
