Sky Diving

Miguel Bunster
 

Hi,

I am looking into a shoot I have coming up where some people are gonna sky dive in tandem.
The camera operators will jump with helmet cams and as I understand they use 5ds. 

I want to use sony a7sii or a7rii or a7riii for the look and auto focus, . This last part is my concern. 

Was thinking just to put a deep stop of T 8.0 and play ti safe to get the needed shots and not rely on auto focus. Planning to use a 24mm and 35mm lens, native E mount. Plus Pola and if needed ND. Ideally just Pola.

As well the tandem jumpers will be using go pros and go pro fussion cameras.

Will be shooting on the ground with Alexa when they land.

The reason of the sony's is that I have matched them better to alexa than other cameras, or better said in color timing able to bring the two close together.

Another option was the Panasonic gh5s or gh5 which i really like but don't know how the auto focus works yet. Haven't testes that but do like the camera a lot.

any input from experience skydiving people would be great!

thank you
M

(my opinion from doing this exact thing with the A7s1 few years back) - Ditch the  Auto focus -  F16 or greater - you’ll be happier…
You can test all this in a park on the ground
Also clean your sensor morning/prep day  of shoot, shoot a white wall - piece of paper - whatever at F16/22  - take it into a laptop, take a grab -  check for crap on sensor, (specks/eyelashes/pubic hair) do it again till it’s all gone. 
Maybe a pro can do better than swabbing the poop deck yourself - good luck 
my 2 cents.

I’ve used a7sii for a couple of years as a B cam and just received a BMD 4k Pocket. I now wouldn’t consider the a7sii again for video work. The colour is spot on, the images are very sharp and very clean. The dynamic range is more than respectable and the ability to shoot raw or prores miles ahead of the Sony’s.

As far as I know it doesn't auto focus but it is touch screen 'tap to focus' which works reasonably well and easy to operate. Its a smaller sensor and at a deep stop you can be confident of a good depth of field.

Just another option I thought you might want to consider.

Can’t speak to skydiving...last time I rigged a camera for that purpose was a Arri16s :)

But... have been doing a fair amount of gimbal work on the A7 cameras this year, and it’s my opinion that among the Sonys, the A7RIII has by far the most reliable autofocus. Not bulletproof, but pretty good.

Hi Miguel,

In my business hours Im a lighting manufacture (Cineo Lighting) but on the weekends im a D Licensed & PRO rated skydiver, Tandem Instructor and Wingsuit coach here in Los Angeles.

Ive worked with several camera fliers using gear ranging from fix and auto focused Sony’s to REDs to full helmet VR rigs. The camera set up youre lusting for absolutely works, my guess is that the contracted camera fliers are using their personally owned “school” equipment that doesn’t require the quality your looking to get and therefore doesn’t justify the personal cost of upgrading. The mounting can be specific to the camera / helmet combo but some mounting plates are universal to 1/4 20 threaded bodies. Auto focus absolutely works but is not a 100% success rate. Sometimes the cameras get confused with the motion and grab the earth below. Be prepared for the possibility of a 2 or 3rd attempt (for that and many reasons). From the experience of having a camera on my head in free fall - smaller the better please, those things are a literal drag.

My personal email is Trish.Maas@.... Please reach out; Id be happy to help especially if you are doing this in LA (perris?). I’ll be working there this weekend and next. Might be able to get a test done for you.

Blue Skies!

Hello,

If you decide to jump eith the A7s2, make sure to turn off image stabilization because it can’t keep up with the speed/g-forces in this situation.

Had a random conversation with a rental manager and I clearly remember they had issues with this (skydiving situation).

Cheers,

Thanks you all for your informative and kind responses!

Sorry for the delay in responding was trapped out of town working.

So they did some tests which will be repeated.

The Gopro fusion works great for its purposes.

Will test as well Go Pro Blacks ideally seven but ut seems it will be 5s.

And will go up again with the sony a7sii or Rii. to test with no auto focus and a deep stop on a 28mm or 20mm lens.

From the first test the rolling shutter seemed to much so will see how a a7rii behaves.

Will keep posted but really interesting the work with the fusion.

Best
