Hey everyone! I’ve finally made the jump into the Sony ecosystem and recently picked up an FX3 as my main powerhouse and an a7S III to serve as a matching B-cam for my freelance video projects. I am absolutely blown away by the low-light performance and the autofocus, but I’m hitting a bit of a wall when it comes to my lens kit—specifically on the wide end.

Most of my work involves high-end real estate walkthroughs and "run-and-gun" travel documentaries. I currently have the 24-70mm GM II, which is a fantastic workhorse, but I’m finding that 24mm just isn't wide enough when I'm trying to capture tight interior spaces or expansive landscapes. One thing that’s been bothering me is the slight 1.1x crop when shooting in 4K 120p on these sensors; it turns my 24mm into something closer to a 27mm, and I’m losing that immersive feeling I need for my slow-motion b-roll.

I’ve been doing some research, but I’m feeling a little overwhelmed by the options. I looked at the Sony 14mm f/1.8 GM, but I’m worried it might be a bit too specialized and the bulbous front element makes using standard filters a headache. On the other hand, the 16-35mm f/4 PZ G seems perfect for gimbal work because of the internal zoom, but I’m concerned about the f/4 aperture when I’m shooting in moodier, dimly lit interiors. I also keep hearing people rave about the 20mm f/1.8 G for its balance of size and sharpness, but is it wide enough to justify the purchase?

I’m really looking for that "sweet spot" of fast autofocus, minimal barrel distortion, and a weight that won't kill my arms during a 10-hour day on a DJI RS3. For those of you who are daily driving the FX3 or a7S III for professional video work, what is your absolute favorite wide-angle lens that balances image quality with practical usability on a gimbal?
