Video newbie Q: 4K camera with best IS
« on: March 13, 2017, 01:55:59 PM »

I'm out of the loop on video technology, so apologies if this question is dated. I'm looking for a 4K camera recommendation which has excellent in camera image stabilization. I'm going to be traveling on an extended trip where weight and bulk has to be kept to a minimum, but want to capture 4K video. This means hand held shooting 90% of the time on boats, hikes and traveling rough. Any recommendations for cameras that have really good IS built in, either mechanical or electronic of both?

Sony a7SII?

It's not really an answer to the question because I've not found in body stabilisation that helpful for the sort of motion you're describing. I've got a Sony A7RII and it certainly helps to have stabilisation, but it's just not on a par with an actual gimbal system for stuff like boats or walking along.

My go-to system is a GH4 on a Ronin gimbal but that's far too heavy for hiking with. I'd consider a Panasonic GH4 on a physical gimbal, something like this:
https://www.amazon.co.uk/Beholder-DS1-Stabilizer-Controller-Max-Weight-Handheld-Gimbal/dp/B01IT5SIOW?tag=top90f-21
(I have no experience of that particular system so do some reading around the various handheld options).


If you don't mind slightly go-pro-esque colours, and being careful with its limited dynamic range, the Osmo+ is very hard to beat:

I've only just got one but am impressed with the footage I've got so far.


Reputedly, the Olympus in body stabilisation is excellent, but I don't know how they are for shooting video.

 Cheers, Hywel

Sony a7SII?

I have a mixed view of my a7sII.

First, it can keep a central subject smooth on something like a fast 1200 hp boat running through a wake.

http://russellrutherford.com/fast_skif.mov

The central subject is level, the rest warps or jellos, though in all fairness this was shot at about 60 knots in very active conditions, though just slightly smooth walking can jello the file and panning must be kept very slow.

The motion file is  low bit rate, and will band in the highlights.   Now the standard thought would be to slightly underexpose and people rave about its low light, high iso capabilities, but mine doesn't.

In fact I did a test in London last week giving it one more chance and did some test stills at 1200 iso at night and compared it to an Olympus em1 mark II and the em1 had more detail.  The sony caked and layered the subject like pushing a file to 8000 iso. 

The battery draw on the Sony is crazy.  It will burn through 70% of a battery just setting the menu up.

Grading the Sony is tough . . . takes 7 to 10 nodes in resolve to get a decent file and is not that great on skin tones.  The only upsides of the sony is its build quality is much better than the first version.

Actually the best lens for it especially if you use any autofocus is the Zeiss/Sony 24-70 A mount with the pdaf adapter.  The issue with using the adapter is you have a very small focus area and in video set to manual exposure you can't lock down the controls.  It goes to some type of auto exposure mode and moves the shutter speed where it wants and also locks the f stop to 3.5.  Very strange.

The Olympus up till the new one was not meant for video through the battery works longer, the menu of the oly is a mess, but it doesn't jello as easily and the stabilization is very good.

Personally though I haven't tested it I'd go with the new Panasonic G5 when it's available.  The new panasonic has a 5 axis stabilization and up to 400 mb/s 422 10 bit,  vs the Sony's tops of 100 mb/s 420, 8 bit.

Once again I have not tried the gh5, but own two gh3's tested the gh4's and the file is more robust and the camera is very easy to set up.  Its like a mini 5d2.

If there is only a downside of micro 43 it's getting to super wide lenses.  There is a leica autofocus 12.5 (25mm equivalent) and if you want to be able to have softer backgrounds you usually need to go to the manual focus voiightlanders at f .95.

The nice thing about micro 4/3 with a light cage is it's easy to mount them in cars and small areas and the gh5 has full sensor readout to 4k and uhd, rather than just crop the center of the sensor.

IMO based on the original question, the Panny GHs are unbeatable and now the GH5 has in body IS.

This from PVC may be of interest. Check out the various videos, there is a lot there

Chris,

I believe your probably right, though I've been fooled before, but Panasonic seems to have thrown a lot in the gh5.  How they handle heat is beyond my knowledge, but other than that it really is a small filmmakers camera.   The cool thing is unlike Sony and Canon, they don't seem too concerned about taking away market share from their more expensive cameras.

For some work I think this camera will be ideal.

IMO
