Sooo, just catching up on this thread. I’ve been shooting real estate and events for years now, and honestly, i’ve tried basically every wide-angle combo for the Sony FX3. For your situation on the DJI RS 3, here is what I recommend based on my experience: * Sony FE 20mm f/1.8 G: This is highkey the secret weapon for gimbal work. It’s super light so your motors won't struggle, and that f/1.8 is *literally* a life saver for dim interiors. Over the years, I've found it has much less edge distortion than the zooms at their widest, which makes your architectural shots look way more professional, you know?
* Sony FE 16-35mm f/2.8 GM II: This is amazing for versatility, but it's heavier. Plus, if you zoom in or out, it can sometimes throw off the balance of the DJI RS 3 slightly, which is annoying mid-shoot. In my experience, the 20mm prime gives that "cinematic" feel more easily because the glass is just so sharp. Anyway, if u prioritize low light and easy balancing, go for the prime! gl!

Seconding the recommendation above for the 20mm! Honestly, if you're doing a lot of gimbal work on the DJI RS 3, the Sony FE 20mm f/1.8 G is basically the perfect middle ground for price and performance. I've used the Sony FE 16-35mm f/2.8 GM II and while it’s incredible glass, the shifting weight when you zoom can be a REAL headache for your gimbal motors if you aren't careful... it just feels safer to stick with a prime for long shoots. A few practical things to consider:
* The 20mm is much lighter, which saves your arms during long event days.
* That extra stop of light at f/1.8 is HUGE for dimly lit architectural shots where you can't always set up lights.
* It’s way more budget-friendly than the GM II, leaving room for other gear. I mean, it really comes down to whether you need that 16mm width, but for most real estate work, 20mm on full-frame is plenty wide without looking too "fisheye." gl with the choice!

I've had a bit of time to think about this and honestly I'm super satisfied with my current setup. For total reliability on a gimbal like the DJI RS3, the Sony FE 16-35mm f/2.8 GM II is hard to beat. It's surprisingly light and the autofocus is just rock solid... I've never had it hunt on me during a shoot. If you're doing a lot of real estate tho, I've been really happy with the Sony FE 20mm f/1.8 G too. It works so well in low light and it's basically weightless on the gimbal.

• 16-35mm: Better for events where you need that zoom range quickly.
• 20mm: Better for tight interiors and low light situations. Both lenses handle distortion really well on the FX3 so you dont have to worry much about that cinematic look. If you can swing the price, the zoom is more of a workhorse, but that 20mm is a fantastic value and honestly feels a bit more nimble when you're moving fast. Let me know if you have more questions about how they balance!

In my experience, wide glass shifts the center of gravity on UR gimbal. Basically:
1. Do u prioritize low-light f-stops?
2. Or focal flexibility?
Dont forget edge distortion!
