Sony FX30 vs Sony A7IV - Rolling Shutter, 4k, 1080, Slow Motion, Low Light Compared 

One of my biggest pet peeves with camera review channels is that they never give their commentary AFTER SHOWING THEIR AB test. Thank you for defining the status quo and making well-structured reviews.

I'm watching it again after 5 months and those videos are so useful in making our purchasing decisions. It's hard to find those more in depth tests. Thanks Mark!

Always grateful you do 1080 comparisons

Still dont know why no one has compared the fx30 to an a6300 or a6400 or a6500 or a6600 since those are the ones that for sure are gonna upgrade like me...

FX30 A7IV and ZV-E10 is my dream trio

Thanks for the rolling shutter test! Very helpful :-)

One of the Best channel for cameras on RU-vid:)

Great video. To me, the A7-4 is the overall winner. Best sharpness, best low light performance and about equal rolling shutter. The choice is easy :)

Now here is some comparison video🤩🤩🤩🤩

Ok, had a chance to take Gravol before the rolling shutter tests….and needed it! Both cameras did well everywhere else, with the A7IV obviously showing its FF muscles in extremely low light. It is an amazing all rounder! Still, I found I usually/slightly preferred the FX 30 in most shots. Likely just a personal preference. Another great video!

Very Very Very helpful test. Thank you very much.

Very helpful! Thanks

I'm glad you did the 1080 test. A lot of cameras don't do so well and judging from your results looks to the case with both of these too. Most of my work my client has no need for 4k, its being delivered over the web so I'd prefer the higher bitrate lower resolution and file size. In addition for multi camera work It's quicker and easier editing exporting 1080 and takes up less hard drive space too. I gather the advantage the fx30 has is lower price tag, smaller form factor, an less expensive apc lenses, while the a7IV is FF and better suited to be hybrid for video and photography withe the viewfinder.

Fast becoming one of my favorite camera channels the passion and excitement is up front and center

Great video! Finally, some questions answered that barely any other reviewer touches. Question: starting the crop comparison in 24p at 2:45 , did you switch immediately to the sigma 16mm on the A7iv or is that the 24mm FE and framed similarly? (I assume all crop tests were the Sigma 16mm on A7iv and FX30, just wanna make sure) :)

This man answering all the comparison question i had lol

Awesome video Mr Handsome! Did you run the rolling shutter test "raw" and/or through catalyst browse? Might there be additional corrections as a result?

Excellent comparison...

Awesome video. Funny enough, I’m not sure which RU-vidr said it but it does appear the A7IV is the best APSC camera you can get😂😂😂? Obviously it’s full frame but between the sharper 1080, the 4k60, the vastly improved rolling shutter, and flexibility to still shoot of course in full frame, it’s awesome. For $700 less, the FX30 still brought with it most of the A7IV plus some extra goodies. Great comparison and really appreciate the work you put in.

Thank you! You the best 🙏

Great Video, the FX 30 is a real beast :) 👍🏻

Great video, the low light test was really helpful for me. One concern I have for the A74 is the over heating issues. Have you done a stress and long use test to determine what it takes for it to overheat? Is the over heating primarily due to temperature operation or internal recording 4k for long times? Or both?

Mark - you are the SHIIIIIIIIT!!!!!!!! You do the tests I really wanna see. I subscribed!

I’m surprised. I like the FX-30 in the dark. I felt like the image was darker but it also looked cleaner to me.

Lol! Hope my wife is not watching! Great video! I'm also in the "Not enough cameras" crowd. Want to get FX30, but also have too many cameras, including the A7IV... 🤣

this one was an interesting one definitely, great video Mark ! Personally I went with the 15mm F1.4 G instead of the Sigma 16mm, I wanted the extra features and fast focusing, I'm just waiting on my camera to arrive, can't wait ! I'll compare it to my GH6 😉

Also can you please let me know if eye focus is disabled while monitoring using the sony imaging PC or smartphone app on the FX 30? Also on the fx30 when you use slow mo 4k60, does it disable Active stabilizationand, focus tracking, and eye autofocus?

Thanks for the video.

I really wanted to grab a fx30 to finally update my old a5100's and a6000. Typhoon damage ruined a lot of my gear and the upgrade will have to wait until I can replace my stuff that got ruined. This RU-vid hobby is getting expensive. Enjoyed the show, it really made staying with crop sensors appear to be a reasonable choice. Cheers.

Dude, thank you! P.S. Rolling shutter test will looks better in vertical split-screen or without cutting frames.

Great job! Thank you!

Thanks for putting some rock music in a RU-vid video in 2023! I’m open to a lot of musical styles, but I’m just sick and tired of lofi beats.

a7iv 1080p vs a7iv aps-c 1080 that was very interesting and unexpected results.

A simplified way to compact this information, The A7IV shoots slightly better images overall due to its slightly better noise performance, you can basically enjoy the same image you would get from an FX30 all the way up to 60fps in APS-C mode in the A7IV, but also benefit from the full-frame sensor for normal content at 24/25fps at the cost of rolling shutter, however, the FX30 does shoot sharper 100/120fps as it can be put in 4k however that's a 1.5x crop onto another 1.5x crop, so for some, it's not that useful, and they seem very similar sharpness wise when shooting 1080p at 100/120fps. Best Approach for my own reference later 4k - Full-Frame at 24/25fps (Looks slightly sharper than the FX30, and benefits from the full-frame sensor at the cost of more rolling shutter) 4k - APS-C at 24/25/50/60fps (Looks the same as the FX30, you can basically enjoy the same image you would get from an FX30 all the way up to 60fps) 1080p - APS-C at 24/25/50/60fps - (Is actually sharper than the FX30 at 1080p) (!) A7IV - Don't use Full-Frame when Shooting 1080p - use APS-C it's sharper. 1080p - Full-Frame - 100/120fps - (Looks very similar but the FX30, BUT the FX30 can go 4k 100/120fps which looks much nicer but also needs to crop onto its already crop sensor) (!) A7IV - Don't use APS-C when shooting 100/120fps use Full-Frame it's sharper.

Really good video. I was wondering about the rolling shutter issue if the fx30, so it was good to see. Its very cool that the A7iv has better rolling shutter in apsc mode. Is it the same speed in 60p as it is in 24p in apsc mode?

You are doing a great job Mark, thank you for your time and effort! Only the rolling shutter test was flawless you mentioned yourself. Numbers and even other tests show FX30 is better in that regard when compared to A7iv in fullframe mode. Cameras should be at same height side by side when doing that test. One other thing could be interesting in the low light test was testing the a7iv in crop mode against fx30. Lol you are too nice and we are greedy! BTW how is the 240p quality compared to 120p in 1080?

I am glad i got the FX3, next to no rolling shutter.

"Because I love to fill up my hard drives..." so true, as I sit here spending the better part of a week transferring literally 50 TB of footage from various HDDs to now bigger, better (and more expensive *sigh*) SSDs as I make the transition completely into a 4k workflow. But I digress, the 4K 120 fps of the FX30 is one of the main selling features for me and I can not wait to get my hands on it.

The more tests I see of the FX30, the happier I am. Put up against a full frame camera like the A7iv, the FX30 holds its own pretty well I'd say. I'm not big on slow motion, but the fact that you can shoot 4K 120 on the FX30 and its sharper than the full frame A7iv speaks volumes on the power of the FX30. Basically, the FX30 is more of a "cinema" camera than the A7iv, which is why I bought it. Very handsome comparison by the way. And the cameras were pretty good, too.

Great video again, Ben! Would you do a Sony ZV-1 (I know you like it :D ) vs Pixel 7/7Pro vs iPhone 14/14Pro test from an everyday use perspective? (sorry for "begging" for it it here in a comment :D)

Thanks ,but i need to see ,fx30 4k120 vs a7iv 1080 120fps to sport video 🙏

I was surprised, in my viewing, how much more detail the IV has in 4k. In fairness, the IV is one of the best "locked off" 4k cameras you can get. Gerald Undone has an A7SIII and but uses the IV for his main shot, because it provides more detailed footage. I'm leaning towards the IV, but I suspect the FX30 would be a nicer camera to to use, with better build and ergonomics for video, plus the audio handle.

Mark, this is your wife speaking, no more cameras, 50000 more subscribers and you can buy one more 😛

Man I’m so torn. Currently have the A7IV but can still return it. I’m using it 90% for sports highlight videos. The one thing I’m missing is 4:2:2 10 bit color in 120 fps and the FX30 has it. If you could only have one camera, which would you choose?

How about Rolling shutter at 1080p 120 for the A7iV?

Damn bruh! That A7iv is as sharp as a razor. I had high hopes with the FX30 but I am disappointed at the sharpness.

Very good test. The only complaint I have is that the cropped comparisons could have been about 3 - 4 seconds longer. I think slow, specially when my body is full of beer (It's friday today...).

What can be done to fix Rolling Shutter on budgets like ZV-E10 Canon R10 or Zv1.

Can you teach us how to use cine Ei?

hi,,sorry what about that famous rolling shutter on that camara fx30? is good for photography? i am choosing if that or A6600...thanks

The rolling shutter is horrible on FX30. It is bad on A7iv too but atleast A7iv is a hybrid. FX30 is supposed to be a cinema camera. Why would Sony put a 26mp sensor in FX30 when its other cine/video cameras have just 10mp to 12mp therefore resulting in minimal RS.

Finally good a7iv 1080p 120p test

I just bought the a7iv. It was the same price as the fx30. I intend to keep the sigma 16mm and sell the other lenses for a 35mm fe

if only A74 have internal fan for heat dissipation, it will be perfect, especially for tropical area

can you please in the future share with us like 10 seconds clip from each camera from the test, via link on google drive so for nerds like me to see without youtube compression and to scale it to 500% to see what I want to see ? I like when youtuber do this and I subcribe to them all

Is the goatee grown only for testing video sharpness?

A7IV will be most people's first choice if they don't already have a camera.

Mark, thk u for ur great vids. Love ur humor too. I am in a pickle situation here. Thinking if I shud get the FX30. I hv BMPCC 4K but it's in service. Its gonna out for a while. Been going back n forth between FX30 n BMPCC 4K. I am wondering if you have used BMPCC 4K in the past. Otherwise, pls take a look and conpare the image to that of the FX30. I don't know if it's my eyes or what, but I find FX30 footages (and other Sony cameras) are kinda "flat" and lifeless. They juz dun hv the pop that BMPCC 4K does. Don't get me wrong, I know that it (FX30) is well built, feature-ful, and its tech specs re thru the roof. Yet the image char, is like flat to me. :( Meanwhile BMPCC 4k (even with its all shortcomings), render images that somewhat hv this palpitable 3D look, alive, and re very pleasing to the eyes. It's similar to the "Leica look". Pls compare it when u hv time. Thx. Keep up the great work.

FX30 looks a tad oversharpened than the A7iv. Looks very much like a smartphone image. On a budget, FX30 is great. If one can stretch the budget, the A7iv is a more organic image in APS-C mode. That said, there's always vintage glass to soften things up.

The FX30 is a very niche camera

I would say I prefer the FX30.

Is clear to me , i have to wait for a7 V…….

1. You use sigma 16mm vs 24mm Gmaster? Why not the new Sony 15mm ? 2. Again, you use the FF 24mm G master in Apsc camera!!! Wrong decision, not the best result with an FF LENS, on Apsc camera!! For the "results", don't blame the cameras neither the lenses!!!

Apparently A6400 4K is quite a bit sharper than FX30. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fm5X92OzQJE.html

A7IV IS BETTER
