Sony A7s II... or

I have a dilemma, I currently shoot with a Sony FS100. It's a great camera as many will attest. However, due to filming in certain confined spaces, e.g., sail boats and other maritime vessels, I need a smaller more compacted camera package. I am concerned with the overheating issue for the A7s II, and am really looking to purchase the Sony FS 5 or FS 7. Can anyone offer either camera alternatives similar to the A7s II or other work-arounds to the heating issues? Thx.

The GH4 is fantastic. It doesn't have the low-light capabilities of the A7s II, but it doesn't have the overheating issues, either. The Panasonic 7-14 f4 lens is a winner (I have one). The Olympus Pro 7-14 f2.8 also looks like a winner. You can also try your luck with a Voightländer 10mm f0.95 to get both wide angle and somewhat shallow depth of field (if that's what you are going for).

GH4 is a great camera however I've been using the Sony A7sII and it's never over heated on me. Especially when we shot in 4k in a studio with red heads heating the room it still didn't over heat. Now overheating is prone to a lot of other Sony Cameras however in my personal experience the A7sII is very good at handling it's heat.

The GH4 is still a good option, the only problems I see is the low light but if you're using it for films then you should have some sort of lighting and the other major problem is the crop sensor which can be easily fixed with some effort and more money. all in all the GH4 is way cheaper than the A7sII and both are reliable cameras to film with. I personally chose Sony since I believed it gave me more options and flexibility which in my opinion it has. The only huge problem I had with the A7sII was the lack of lenses however it seems to be catching up and now have a lot of good glass to it's name.

I've heard of overheating issues but for myself, I've never had that problem. But to work around heating issues, I've read people use external recorders.

I've used quite a lot the A7sII for video and it's a great camera for video, also it doesn't overheated easily. It happend only once and it was in hot summer (32°c), in bright sun and I was shooting an interview hand held so it was really the worst scenario, even me I was overheating :-) I had to change batteries every 10-15min so it was ennoying but it didn't forbid me to shoot. If you use a cage it help a lot.

Hey dude -

I would go with the Sony, as I imagine the Sony FS has the same SLOG as the Sony, thus much easier to match in post.

The GH4 is a bloody lovely camera too and shouldn't be over looked, perhaps look up online some shot matches from the GH4 to Sony cams to see how it is done?

Also don't forget if you're shooting on a GH4 all of the shots will be cropped as it's Micro 4 thirds sensor. However I expect you already knew that :)

I've also never really heard of the overheating problems with the Sony A7s II. I've an A7s myself and never had any problems with it at all.

Hope all this info helps and you choose the right camera for you :)

Paul Leeming's "Leeming LUT One" LUTs are designed to match the color of the Panasonic GH4 and the Sony A7S cameras as perfectly as possible.

I bought an a7Sii last April and ran into this problem after about 45 minutes of continuous recording at 75F room temperature. Sony came out with a firmware update that they said would alleviate this prob!em when used in conjunction with their expensive pistol grip.

This grip moves the battery from the camera body to the grip. So that led me to believe the battery was adding heat to the camera. I added an external 3.7V USB battery (5V works better) to reduce the load on the internal battery with the idea it would reduce the amount of heat introduced by the Sony battery.

With the firmware updated, external battery and the monitor pulled away from the back of the camera to expose the back of the camera body to ambient air i was able to record for two hours before I stopped the test without any shutdown due to heat.

A feature of the Sony firmware is to automatically stop recording after 30 minutes so I monitored the recording time and restarted it immediately after it stopped. This could be a pain if you're doing event recording but it is manageable. I wish Sony would fix this because it is not really needed.

It's not a big deal to tape a USB battery to a tripod leg. And you'll be able to record for over two hours without having to change any batteries. If you're shooting handheld I doubt you'll be doing 30 minute takes so you should not need to worry about the overheating. I really like my a7Sii. I've used it to record musical and stage performances without any overheating issues.

How are you able to deal with the extreme rolling shutter issues? I seen it in every pan/tilt on those cameras, they seem terrible at handling movement.

I have never had my a7sII overheat in any configuration, though perhaps if you ran it for a very long time in 4K mode (I have never run over an hour)... The FS5 is great but IMO the image is basically the same as a7sii/a6300 and I'm not particularly fond of it (though add the $500 upgrade and a $2k recorder and youve got 4k 60p raw on FS5).
