Overheating problem, will return it

[Komjazz]

Been using this camera for about a week, this is amazing camera, I bought it from best buy which is the last one they have in their stock.
As I also work as a musician. Be able to continue recording in 4K while control it with my phone is a must.

The unit that I got shut down often, I use it mostly outdoor and I live in Miami which is hot.

I'll return it today, sadly, this is the thing that Sony should be able to it before the camera came out. This is unacceptable for me. I paid a lot of money for this, expecting professional camera, but it's just another unreliable camera. Think about it, if you interview someone and the camera shut down between the interview, that just not good.

The camera is amazing on taking pictures, but as I say, we paid a lot of money for this. I think Sony just want push to ship and lunch this as fast as they could and they don't care. I just hope that they will come up with new firmware soon, then I'll buy it again.

If you just want to take the pictures with this camera that's great, but if Sony advertise as 4K internal recording and it does work just a little while, that's kind of not true.

Please Sony, fix this!!

Here is another person that have this overheating problem

This is just another silly attack on a compact still camera, because it isn't a full blown video camera. I think that the user would have issues with a video camera, considering the abusive conditions. Why the low overall score based on a secondary feature and why post this at all? We all know that 4K video has a 25 minute limitation as stated in the manual under noemal conditions. Helpfulness=0

Dear Dave,

I didn't mean to attack anyone or anything, I just want to point out the problem that I got from this camera. If it's not a full blown video camera, why advertised it as such?

I have FDR AX-33 and Ax-100 they work great. I didn't abusive anything why do you thinking like that?

I don't know about you, but the reason that I posted is that Sony should fix this, even it's just a secondary feature for you. And I'm sorry, I don't know that 4K video has a 25min. limitation. How about you record 4K first 10 min. stop then another 10min, stop and another 10, stop and another 10 then it's shut down? Is that call reliable for you?

If this post is not helping you then, I'm sorry.

I think it is not very fair to NOT mention the over heating recording internal 4K without mentioning that you are also controlling camera via wifi on the same breath. You did mentioned it in passing but the current draw with such a set up will cause even the battery to heat up a lot more than "usual", compounding the problem.

An external power adapter (fake battery) would probably be a good idea in such 4K wifi situation.

Thank you for your comment,

What I did is, I have an external battery that connected to the camera via USB. I'm not sure that is cause more heat or not. But that is one way that I could do like.

Best,

Without some idea of the conditions you're shooting in, this review doesn't tell us much.

Also, I hate to say it, but another Canon user with a couple of posts joined yesterday just to rag on the A7RII and say they're returning it. How many of these does that make, now?

And August in Miami isn't that hot. It's certainly not desert conditions hot, or even Oklahoma/Texas/mid-southwest hot (which was over 100 degrees and a heat index of 120 a week ago)

Places that hit over 90deg F during the summer are very common places on earth and a camera should be able to operate in those conditions. If an A7Rii cannot do this, I would say it is a design flaw.

Maybe people are not ragging on it, but are instead serious about it's problems. A lot of Canon people are probably investigating moving to the camera due to the extra DR and the supposed ability to focus Canon glass well. I would assume that not all of these people would be happy with the camera. Sony has never made a perfect product in it's history, and they always leave something out keeping a device from being perfect... And it would be perfectly logical for some Canon people to not think the A7Rii is the bees knees. It is also good for them to voice their opinion so maybe Sony gets it right next time.

If Sony is going to market the camera as a video capable camera, it should be able to perform that function to respectable standards in common conditions for those who buy it for it's video functions.

Personally I could care less about the video aspect as I prefer a real video camera form factor vs. my dslr and an erector set. But if the A7Rii cannot shoot 30min of video without shutting down, can it shoot a 2 hr star trail photo without shutting down?

If you were located in Hawaii I would be out hunting the best buys for an open box deal. I don't do video much so I could care less about heating issues.

So I'm sure there are plenty of ways to improve the performance and reduce the overheating but I have a different question.

If you use the A7RII with an external recorder like a Shogun can you basically reduce the heat problem completely? Is it engineered such that without internal recording there is no heat problem?

I ask because I'm fairly new to 4K recording and the current short run times are good enough for me know but if I do need longer times in the future is there an solution with an external recorder.

I bought the camera for stills and I don't know how much, if any 4K recording I will be doing, but I know as an engineer of mobile devices the heat problem is not going away for anyone. So has the camera been engineered in such away that an external recorder work without the camera overheating? If so great, there's a path from short to long recording times. If not then people should be cautious. It would be great if an individual who owns a A7s and Shogun could get their hands on an A7RII and do such a test.

Heat will remain as a limitation for most unless they build sensors that only have 3840 x 2160 or something larger with no extra overhead of 42 megapixels. And of course when 8K comes along the problem will be there as well.

You think those big flat cell phones came about just because you liked the large screen? They were driven by the large screen, the need to spread out the heat, and the need for large batteries to drive all the electronics. Key thing though is the thermal density of the internal circuitry is one of the biggest factors the handset and tablet guys fight every day. The high performance video guys will be fighting it every day as well.

Having to buy a shogun to shoot your kid's play in 4k is a bad solution though. That is a pretty pricey piece of equipment for a non-pro video shooter, which is the majority of people buying these cameras. The camera should be able to do it internally.

I think Sony's problems really stem from trying to push the form factor down in size to a point where it cannot adequately dissipate heat. DSLR's do not suffer from these issues, as they have a lot of room for a big heat sink. I haven't torn an A7 apart, but I assume the camera's outer shell is being used as the heatsink for the processors..... And you cannot have much of a heatsink on the sensor due to camera size, and the fact the sensor needs to stay light weight for IBIS to function well.

The A7's are simply too small and need to grow in size a bit.. This would not just help with heat dissipation but also handling of bigger lenses. The sole reason why the FE system got stuck with a 24-70/4 and 70-200/4 instead of F2.8 zoom's is because the camera isn't big enough to handle them well.

Also, I hate to say it, but another Canon user with a couple of posts joined yesterday just to rag on the A7RII and say they're returning it. How many of these does that make, now?

Sadly I think most (but not all) of the people posting negatively about the camera are astroturfers.

Unfortunately marketing companies do this all the time. I say this as someone who has been carrying an iPhone six plus in his jeans pocket for almost a year without it even thinking about bending half a micron, yet someone managed to bend theirs in only a few days (helped by the dollars of a rival phone company of course!).

There's no real way to know if posters are genuine or not - although some obviously aren't. They tend to post comments with titles like: "Is the poor image quality I'm getting the same as all those other people complaining", etc.. The mods should delete those posts.

I suppose we could ask people to post a photo of their A7rii, to prove they've got one but it would be a shame to do that. Come to think of it I don't think I have seen an actual picture of a camera from anyone here.

One would expect that too, but no complaints here.....So why would Sony be targetted only, when GH4 is a real threat for Canons APS-c cams...And quite popular...

I suspect the battery under these conditions is part of (if not the main) heat source so I am trying to suggest taking it out of the heat equation so external USB power would not help. Of course I only suggested this due to your "unusual" use of wifi phone control. In any case, there is always a price to pay for miniaturization. Too bad it doesn't work out for your application. I am holding out for A99II.

You know, I tested another Sony Action cam, which is FDR-X1000V, it's really small, I recorded the 4K XAVC S 4K: 3840 x 2160 30p/60Mbps (can't do 30p/100Mbps because of the 128GB micro SD card is not U3.) It can go on for 2 hours via I'm controlling it with my phone. It's got warm but it's still works. I know they use different sensors or system. But that's another small cam Sony make without overheating problem (with WIFI and GPS on too!)

I'm sorry that you guys feel it that way, I'm real and just normal user, I didn't work for canon, that's why I try to move to Sony. And I didn't say it a bad camera, I say it's an amazing camera for photos but not for 4K video. Is that really bad? and I also have some photo from the a7RII too. did you check my profile? Or if it's not there then just google my name "komjazz" add me in facebook. But if this is really bad I'll stop post and answer now.

Perhaps not a Canon (or other) shill, but as others have asked for details of your experience, it seems lacking in that regard. That leaves folks to fill in the blanks, so to speak!

And August in Miami isn't that hot. It's certainly not desert conditions hot, or even Oklahoma/Texas/mid-southwest hot (which was over 100 degrees and a heat index of 120 a week ago)

90+ with 70+% humidity is pretty damned hot and humid, as it was yesterday.

Places that hit over 90deg F during the summer are very common places on earth and a camera should be able to operate in those conditions. If an A7Rii cannot do this, I would say it is a design flaw.

Nope. You shouldn't expect to run 4K video endlessly with the sun beating on your gear in 90+ degree heat. That's an insane expectation, IMO. My cell phone won't even work if I leave it on a picnic table for more than 10 minutes!

Maybe people are not ragging on it, but are instead serious about it's problems.

Who cares? Can you record 4K video with another non-camcorder camera in 90-100 degrees? Another user in this thread cited 29 minutes of 4K video, so OP was either subjecting his camera to extreme conditions as mentioned here, or has a defective unit.

Thank you Steve W. for such a good comment,

I believe that is one option for now, there is some test on youtube that they use the A7RII with an external recorder. I totally agree with you, but then

1. they should advertised as this camera can record 4K 10min. (or how long that not gonna affect the camera's funtions.) and set that as a time limit. like RX100 IV that can shoot 4K just 5 min.

Agreed. Stating the capabilities honestly is a necessary requirement of any vendor. Deception will only get you angry customers. Tell it like it really is.

2. How do you know what will happen if camera overheat many times? Is it gonna damage the sensors? in the long run it's not sound good for me. But if you shoot just still then that is a camera for you.

You don't. Excessive heat can cause long term reliability problems if your not designed for it. You can manage it if you know the environment. Guys who design electronics for under the hood of a car know what its all about.

3. If they do that then it will help a lot. Because you don't want lost control (the camera shut down and nothing you can do.) of your camera.

If its going to shut down it should do it gracefully and with sufficient warning. Pushing it to the edge where it just dies doesn't work for anyone IMHO.

Best,

Kom

By the way this is a great thread no mater what people claim. For those serious about video need to know what they will get without having to buy the product and end up returning it. Keep up the good work.

I don't know if its form factor. What other full frame cameras with high pixel count support 4K video? Neither Nikon or Canon have anything in this price range that support 4K. I haven't studied the market but most appear to have Super35 size sensors with much lower pixel count.

Sony could have stuck with the A-mount and avoided some of these problems but they pushed ahead with a concept the market wanted. It has limitations put the two lens mounts have backed them into a corner in some ways. They can't support a bigger battery, f/2.8 zooms challenge the balance of the camera in some ways, but the so far I'm OK with the trade-of of the 16-35/4, 24-70/4, 70-200/4 and the 35/2.8, 55/1.8, along with Batis and Loxia. I haven't seen the 35/1.4 or 90/2.8 but based on my Canon L glass I'm sure I can translate the size.

I know I can pack my A7RII, 16-35, 55, and 70-200 in a smaller package than my 5DIII and the 16-35/2.8, 24-70/2.8 and 70-200/2.8.

The new design has what we call a power path charger. This is what allows the camera to charge the battery and power the camera. This combo can actually demand higher current and produce more heat. If its a 0.7C charger than you'll get > 700 mA for charging a battery and then what ever the camera requires to run it. So if it take 1.5A to run the electronics you may get over 2.2A into the camera. New phones with large batteries have exactly the same problem. You create too much heat inside the phone/camera.

If you can run the charger without the battery or if the battery starts out fully charge and then attach the charger you may get a lower current and then less power being used by the camera.

Or if it's not there then just google my name "komjazz" add me in facebook. But if this is really bad I'll stop post and answer now.

Perhaps not a Canon (or other) shill, but as others have asked for details of your experience, it seems lacking in that regard. That leaves folks to fill in the blanks, so to speak!

Then perhaps you look up in other comments that I already answer some details that you were asking. Did you check out my galleries? What things that I do make you said that I'm not honest with this? What more do you need or should I just delete myself and this posted from this forum? What's wrong to point out something that I don't like in this camera?? If I want to make this camera look bad, there are many other ways.

I answer most of your question if you see other comments too, there are more data and details, I'm not good at English but I still try to explain to you about my point. And I didn't say that my review is good, it's just my expreriance with the camera. I really want Sony to improve in this overheat issue, didn't you???

Please, stop looking me in bad way, that's not my intention at all, I hope we can all be friends here!

Best Regards,

Kom

So I'm sure there are plenty of ways to improve the performance and reduce the overheating but I have a different question.

If you use the A7RII with an external recorder like a Shogun can you basically reduce the heat problem completely? Is it engineered such that without internal recording there is no heat problem?

I ask because I'm fairly new to 4K recording and the current short run times are good enough for me know but if I do need longer times in the future is there an solution with an external recorder.

I bought the camera for stills and I don't know how much, if any 4K recording I will be doing, but I know as an engineer of mobile devices the heat problem is not going away for anyone. So has the camera been engineered in such away that an external recorder work without the camera overheating? If so great, there's a path from short to long recording times. If not then people should be cautious. It would be great if an individual who owns a A7s and Shogun could get their hands on an A7RII and do such a test.

Heat will remain as a limitation for most unless they build sensors that only have 3840 x 2160 or something larger with no extra overhead of 42 megapixels. And of course when 8K comes along the problem will be there as well.

You think those big flat cell phones came about just because you liked the large screen? They were driven by the large screen, the need to spread out the heat, and the need for large batteries to drive all the electronics. Key thing though is the thermal density of the internal circuitry is one of the biggest factors the handset and tablet guys fight every day. The high performance video guys will be fighting it every day as well.

Thank you Steve W. for such a good comment,

I believe that is one option for now, there is some test on youtube that they use the A7RII with an external recorder. I totally agree with you, but then

1. they should advertised as this camera can record 4K 10min. (or how long that not gonna affect the camera's funtions.) and set that as a time limit. like RX100 IV that can shoot 4K just 5 min.

Agreed. Stating the capabilities honestly is a necessary requirement of any vendor. Deception will only get you angry customers. Tell it like it really is.

2. How do you know what will happen if camera overheat many times? Is it gonna damage the sensors? in the long run it's not sound good for me. But if you shoot just still then that is a camera for you.

You don't. Excessive heat can cause long term reliability problems if your not designed for it. You can manage it if you know the environment. Guys who design electronics for under the hood of a car know what its all about.

3. If they do that then it will help a lot. Because you don't want lost control (the camera shut down and nothing you can do.) of your camera.

If its going to shut down it should do it gracefully and with sufficient warning. Pushing it to the edge where it just dies doesn't work for anyone IMHO.

By the way this is a great thread no mater what people claim. For those serious about video need to know what they will get without having to buy the product and end up returning it. Keep up the good work.

Thank you for understand my point Steve W.

Cheers,

Without some idea of the conditions you're shooting in, this review doesn't tell us much.

Also, I hate to say it, but another Canon user with a couple of posts joined yesterday just to rag on the A7RII and say they're returning it. How many of these does that make, now?

And August in Miami isn't that hot. It's certainly not desert conditions hot, or even Oklahoma/Texas/mid-southwest hot (which was over 100 degrees and a heat index of 120 a week ago)

90+ with 70+% humidity is pretty damned hot and humid, as it was yesterday.

Places that hit over 90deg F during the summer are very common places on earth and a camera should be able to operate in those conditions. If an A7Rii cannot do this, I would say it is a design flaw.

Nope. You shouldn't expect to run 4K video endlessly with the sun beating on your gear in 90+ degree heat. That's an insane expectation, IMO. My cell phone won't even work if I leave it on a picnic table for more than 10 minutes!

I didn't run it endlessly and not with the sun beating at my gear.

I used it in a normal environment. Did you read other comments about how I used it?

Maybe people are not ragging on it, but are instead serious about it's problems.

Who cares? Can you record 4K video with another non-camcorder camera in 90-100 degrees? Another user in this thread cited 29 minutes of 4K video, so OP was either subjecting his camera to extreme conditions as mentioned here, or has a defective unit.

I do care, that's why I write this review and YES, I believe that GH4 maybe can do better than that in the same condition. As I said I didn't used it in extreme conditions.

One question for you, do you want Sony to fix this? (even it's not a problem for you) or it's ok for you to let it go? Don't you want them to make a better products? better cameras? How are they gonna know about this if we (consumer) do not say that it's unacceptable to launch a product like this??

Best,
