Sony FX6 Rig vs. Sony FX3a: Which One is Right for Your Production Needs?
Choosing Between the FX6 and FX3a for Filmmaking
When it comes to Sony’s cinema lineup, two cameras dominate the conversation for independent filmmakers, people working without a Hollywood budget, and run-and-gun shooters: the Sony FX6 and the Sony FX3a. Both cameras offer full-frame sensors, incredible low-light performance, and professional-grade video quality, but they serve different needs in the production world.
This blog is a pretty basic breakdown of what you can expect with the FX6 vs. the FX3a. I will not be diving into codecs on this blog because TBH I usually shoot in DCI but honestly just don’t want to get into it with this blog. I think the most important thing to note here are that the FX6 has built-in ND filters while the FX3a does not, and that FX3a can take photos while the FX6 can’t!
I’ve used both of these cameras for different productions and honestly I think that they’re both amazing cameras - you’ll be happy with whichever camera you end up going with. However, I’ll just admit that I think that the FX6’s image just looks better. I don’t know exactly why, maybe be cause while shooting with it I feel a little more inspired to get sick shots - but that’s just how I feel.
TL;DR
Look, if you need a compact camera with a small profile and you don’t mind using an ND filter on your lens - the FX3a might be the right fit for you. The FX3a is a powerful camera that produces a beautiful image - one that is practically identical to the FX6. It’s a serious piece of equipment that can stand on its own. PLUS, and this is important to some of us, the FX3a can take photos while the FX6 cannot! In my opinion, that gives the FX3a major brownie points. I am in no way a photographer, but sometimes when I’m on set I like to snap a few photos and share those with clients! Other things to note about the FX3a - it a has a built-in cooling system and can record longer than 30 minutes, or until your cards run out, and this is the choice for gimbal shooters. It punches above it’s price point. It really delivers close to the FX6.
The FX6’s biggest benefit is that it has built-in ND filters that make run-and-gun shooting a bit easier, and it offers a lot more room on the body to onboard accessories.
Truly, these are the biggest differences between the two cameras. Audio capabilities - same. Image quality - practically the same (no one but the most nit-picky professionals can tell the difference). END OF TL;DR!
