The TRUTH About Battery Life: Sony a7 IV VS. a7S III, a7 III
ฝัง
- เผยแพร่เมื่อ 21 ก.ค. 2024
- What kind of realistic battery life can you expect out of the Sony a7 IV? How does it stack up to other popular Sony Alpha cameras like the a7S III, and the a7 III? And furthermore, are there any unique hacks or tricks that may extend battery life a bit longer when using these cameras?
In this video, I'll go through what results I found testing the battery life on the a7 IV, a7S III and a7 III and the range of results I witnessed doing various tests recording 4K 24p footage. I'll also discuss the many conditions and factors I used to make testing this as consistent as possible across each of these cameras. And, I'll discuss the one mode in particular that may help to get a little extra battery life out of certain Sony cameras.
For those thinking about cameras not covered here like the FX3, a1, a7R IV and a7R III, a9 and a9 II - all of which use the same Sony NP-FZ100 battery - this should still provide good insight into what battery life you can expect using those models as well.

I’m just barely getting into photography and somehow stumbled upon your channel. I am really grateful for your content and hope to see you Garner a much bigger following
Thanks, I appreciate that; a lot more content to come!
Good video good explanation good job short video but a lot of information 👍 thanks
Thanks John, glad you like it!
Thank you for this. Excellent comparison
No problem David, glad it helped!
Great video, thanks! What about different codecs? Maybe it's a good idea for another video to compare different codecs and settings like XAVCS vs XAVC HS or 8 bit vs 10 bit?
No problem! That's a good idea for a future video, for sure.
What are you recording on for this video and what lense are you using this looks so fantastic dude!
Thanks! This was shot on my Sony a7 IV and the 20mm G f/1.8 lens.
Very interesting comparison. I have noticed the same as you in the A74 that the battery is exhausted in less time. Maybe you have to test the same battery in the 3 models. What stabilization you use in A74?
Yeah, same exact battery in all of the models would be another interesting test. I turned stabilization off on all of the cameras, but they were just sitting statically on a table while testing anyway.
@@andrewsaraceni thanks for the reply. Which stabilization mode you use in general? (not in this test)
@@labrostraveller No problem, usually SteadyShot Standard unless I'm going handheld, and then I'll use Active. And checking the video again, looks like I actually left them in Standard mode during testing.
Hi Andrew, is this recommended battery type when I own A7S II? Thanks
Hey, no the a7S II uses an older/smaller battery, the NP-FW50: amzn.to/3QI7BSP
which one would u recommend? SB-C PD mini V-Mount from ZGCiney 99Wh 14.8V 6800mAh or Moman Power 99 V Lock D-Tap Battery 99Wh/14.4V ?
Honestly, can't say I'm familiar with either of them. I tend to stick to the bigger names for V-Mount batteries (e.g. Anton Bauer, bebob, Core SWX)
does crop mode video on the a74 effect autofocus?
No, all AF functionality works as expected in APS-C crop mode.
Thanks for the video! I recently bought the a7 IV. On day 1, I was setting up the camera. Just navigating the menus and customizing buttons. It drained the battery very fast. That surprised me. And it got super hot, but never gave me a warning or turned off. However it was very warm to touch. I had the screen out and the memory card door open to dissipate the heat. I was not sure if I needed a firmware update or something. But coming from the a7S III, I noticed the battery life and the heat right away.
Also, I'm curious How much more battery Active stabilization takes than Standard stabilization, or off?
Thanks again!
No problem! Yeah the a7 IV definitely seems to generate more heat than the a7S III; it's certainly more hot to the touch. Only anecdotal, but I haven't seen a noticeable difference running the camera between the different stabilization modes.
@@andrewsaraceni I think it has to do with the 33 megapixels and the metarials that body is made of. I think it's more plastic than the a7S III. I think that's one of the ways they were able to price it as such.
@@JamesJones10 I'm almost leaving Canon going for the a7siii, I'm a photographer who likes high iso, normally using 6400 on my 5d mk iii, and not going the expected way to Canon R5 because I don't crop, so 45mpx are a waste of storage for me. And the 12mpx from the 7siii are absolutely enough even that this camera is almost only used by videographers. The question is: anybody have an ideia of how many photos can I take with one charged battery? Thanks and congratulations for the video Andrew, hugs from Brazil!!!
@@leokerk I dont know for sure. I have taken lots of photos with the a7siii. I have never drained the battery thought doing so. I would guess around 500 photos. If battery life and the amount of you can take on on battery is what you are loooking for I would suggest the a7iii. It has the best battery life of all the a7 bodys.
@@JamesJones10 thank you so much! At BH they say the 7siii would take around 600 shots, while the 7iv 520 and say nothing about the 7iii, I was waiting for years for the Siii, amazed with the abilities of the Sii, I think this lady will make me happy! No mirror-less will be compared to a dslr, my Mk iii goes easy to 2k photos with one charge, definitely will need a battery grip!
Hello there! I bought Sony alpha 7IV and i think, its draining to fast. Is that normal with this camara? Thank you for reply :) Wish you just the best.
Depends on how fast and what recording settings (e.g. frame rate, resolution, codec) you're using. I'd check out my battery life tips video to make sure you're using the optimal settings there too: th-cam.com/video/oBxKiaeNg7E/w-d-xo.html
What camera are you using for this video
I tested the a7 IV, a7S III and a7 III, but the talking head was filmed with the a7 IV.
Using two card slots can cause the battery to run out faster?
If you're doing dual/simultaneous recording, that can have an impact on battery life.
Just bought the a7iv. Charging it for the first time felt like it took so long, after checking on google it says the charge time is 310 minutes which seems like a long time. I was charging it with the cables provided in the box. Does anyone know if buying a seperate charge dock for the batteries will charge the battery faster or does it really take that long to charge batteries on the a7iv?
Also I will be looking at buying a second battery, Is it true that the not original sony batteries make the a7iv overheat more/faster? hearing all the issues with the a7iv overheating makes me not want to buy other brand batteries since i've heard they overheat the camera faster.
Charging through the camera will always take longer. It doesn't come with the a7 IV, but it's definitely worth picking up Sony's BC-QZ1 charger for their NP-FZ100 batteries. It can charge one of the batteries in about 2.5 hours. For Sony cameras, I tend to buy Sony brand batteries only and stay away from third-party - the latter are generally more trouble than it's worth.
@@andrewsaraceni thanks for the reply. That’s what I was thinking charging the battery through the camera would take longer. Do you know if there is a difference between charging the battery with the Sony charging dock vs charging with a different brand dock for example newell?
@@EmanuelFilms No problem! Some of them might support fast charging, but others might not. Depends on the model, but I basically only stick with the Sony chargers for these batteries in particular.
Hello! Got my Sony a7iv recently, when I turn the camera off with a fully charged battery and put it away for a few hours, the battery charge percentage drops drastically on restart. Went from 100% to 59% in 12 hours without attached lens. Is that normal?
For an older Sony battery, that's not entirely unexpected. As long as it doesn't continue dropping that drastically, it should be fine. If it does, the battery might have an issue.
Thank you!! The problem is that the camera is brand new, as is the battery(( I tried another battery with this body, the result is the same, I'm afraid it's a defective camera, but I can't find similar cases anywhere
Hello sir.. Can sony a7s Mark iii record 4k 60fps up to 4 hours? I want to use sony a7siii for street vlogs in urban areas ??
You would need two batteries or an external battery (e.g. Anton Bauer Titon Base) to get 4 hours of recording.
@@andrewsaraceni Thank you. Very helpful
What does it mean when it says battery exhausted?
Time to charge your batteries. 🙂
Brand new camera took 3 hours to charge. 100% battery I played with the camera settings for 15- 2o minutes and it was already down 80% battery life is this normal
This is the a7 IV, or a different Sony camera? I'd recommend checking out another video on my channel talking about battery life tips/tricks: th-cam.com/video/oBxKiaeNg7E/w-d-xo.html
Why does one of my battery’s say Japan only & my other one says us and Canada & Japan
That's on the side of the battery? I think those are just recycling labels.
Thanks!
No problem!
