Sony FX30 VS Sony A7S III Comparison Differences

I’m going to cover the similarities and differences between the Sony FX30 vs Sony A7S III so that you can make a better decision on which camera is right for you.

Now Sony comes out with the FX30 which is kind of like the the beast of all APS-C cameras it’s the baby of the Sony FX3 so if you are thinking to get the FX30 or to go for a full-frame camera and spend the money more and get A7S III.

the A7S III is a perfect camera for its price but when we look at the Panasonic S5 that has everything you want features the best stabilization in a camera in that range.

the Sony A7 IV which is a hybrid camera with great autofocus and when we compare with S5 the Panasonic S5 have an amorphic support they both shoot 10-bit 4:2:2 4K 60 but in my case A7 IV is a little bit better in certain ways.

So, if you are coming from a camera like Sony A6400 which is an amazing camera that features an aps-c crop sensor except ne thing I don’t like has no stabilization and you want to switch with an APS-C camera like FX30.

You can includ lenses, SD cards it’s got an amorphic mode built into it, a full-frame camera and is priced less money than the FX30.

the FX30 has a great stabilization but this Panasonic S5 has the capabilities of twice or three times also you can use the eye piece with S5 and the viewfinder whereas the FX30 does not have a viewfinder and you mast use an external monitor.

I think the Panasonic S5 is the way to go it’s not really that expensive but it’s nothing compared to the Sony FX3 but now lets stick about FX30 and A7S III and see which camera is right for you.

What Are Similarities Between Sony FX30 vs Sony A7S III?

When it comes at similarities both cameras have a Bionzx XR processor and Dual Base ISO only difference is the Dual base ISO is different the Sony FX30 comes in at 800 and 2500 whereas the A7S III comes in at 640 and 12 800.

When it comes to video similarities both cameras can shoot in 4k up to 120 and 1080 up to 240 only difference here is when shooting in 4k 120 the FX30 does have a small 1.6 crop and the Sony A7S III has an even smaller 1.1 times crop.

Both cameras can shoot in 4:2:2 10-bit in terms of Lens both use Sony E-mount, the same batteries, both features five axis in-body stabilization, both have the same Max shutter at 1/8000 both use the same memory cards and have built-in flash, both have a full-size HDMI out and, microphone and headphone ports for monitoring your audio.

When it comes to screen both have fully articulating touchscreen LCD display swhich three inches but they are different in resolution the FX30 display has 2.36 million dots whereas the A7S III only has 1.4 million dots.

Both cameras have Wi-Fi and USB but the FX30 actually has a Gen 2 USB which will be twice as fast as the A7S III. Both cameras have the same exact sensor the EXMOR R CMOS but they are different in the size the FX30 is a APS-C and the A7S III is full frame.

What Are Differences Between FX30 Over A7S III?

When we compare both cameras and see differences that come from both its is really where you’re going to find which one of these two cameras is better for you its really matter what differences we looking for the outsides and the ergonomics.

the difference between the FX30 and the A7S III is the sensor size FX30 being aps-c and A7S III being full frame, also there is a big difference when it comes to the price you can buy two bodies of the FX30 for the price of one A7S III.

the FX30 is video cinema line whereas the A7S III is made more for the hybrid shooter so you’re going to get a cooling fan with the FX30 for longer shoots without any overheat, whereas the A7S III just has passive coolin which you can shoot in 4k 60 and 4K 120 in hot weather with no overheat.

But I can say when you shoot in 4k 120 with FX30 in the blazing sun probably you will facing with heating issues because the FX30 is a cinema camera wich features five different mounting points like lights microphones and monitors whereas the A7S III doesn’t have any mounting points except the quarter Mount.

the A7S III is a camera more for hybrid shooters and doing photography the FX30 has 26 megapixels whereas the A7S III has 12 megapixels and that’s more than half.

EVF

In terms of the EVF comparison A7S III comes with an evf because the A7S III is more of the hybrid shooter camera whereas the FX30 does not so when it comes to me it’s not surprising that the FX30 doesn’t have an evf because it’s made first for video first.

Autofocus

When it comes to autofocus the A7S III comes out on top because the FX30 has 495 Focus points and the A7S III has 759.

And when it comes to dialing in the focus the FX30 has something the A7S III doesn’t have and that’s Focus mapping and its just a way better to figure out what you’re focusing if you’re shooting with a lower aperture.

ISO

In terms of picture profiles the A7S III does have Cinetone but it doesn’t have cine EI and when you shoot an S-log-3 and you use dual base ISO you’re going to get a very similar look than that cine EI.

Another thing when you are shooting with higher ISO there’s going to be a lot more noise compared to camera with a full-frame and this is a huge difference between APS-C and Full Frame cameras.

Lowlight Performance

When we compare atthe lowlight performance FX30 definitely will be better out of the a7s III because it is a full frame sensor.

Lenses

Because the FX30 is aps-c camera the lenses that you’re going to buy coming a lot cheaper than buying full-frame lenses like the A7S III so that means you can buy more lenses and you can also use full-frame lenses, it means the FX30 is more cost effective.

Weight and Size

the weight of both cameras when you include the battery and the memory card the FX30 comes in at 646 grams and the A7S III comes in at 699 grams there’s not much of a weight difference except if you put a monitor on the A7S III it starts to get pretty heavy. When it comes to the size difference the FX30 is alittle bit wider a bit shorter but more deep in comparison with A7S III.

Price

Sony FX30 VS Sony A7S III Price

So, when it comes to the price the A7S III is priced at $3,500 at BH Photo, and you can find the same price at Adorama whereas the FX30 is Priced at $1,800 at BH Photo and the same price at Adorama.

This is a really big difference in prices but I believe if you want to use the XLR Mount handle thing which is really great especially if you’re using XLR microphones or anything like that it’s more expensive and it’s coming at $2,200 for FX30.

Which Cameras is Right for You?

The A7S III is full frame and it has a viewfinder compared to the FX30 which is just an amazing video camera both of these cameras are excellent for weddings so FX30 is camera for someone who might be upgrading from the Sony ZV-E10 or the Sony ZV-1.

So, you will get a better low light performance out of the A7S III but the FX30 would be an awesome B camera especially when you’re outside getting some of those slow motion shots.

Why You Should Buy FX30 Over A7S III?

Both cameras have two memory slots so the two card slots on both of these cameras are a huge benefit and the reason why you should buy the FX30 over A7S III is because it does offer so much more than the A7S III.

Why You Should Buy A7S III Over FX30?

the Sony A7S III is a great choice for people who do hybrid shooting video and photography and the FX30 is going to be a great Cinema line or if you’re out there doing documentaries.
