I Shot at f/4 All Weekend to Test the Fuji GFX100RF Hype… Here’s What I Learned

There’s a lot of buzz around the new Fuji GFX100RF—a compact medium format camera that’s got everyone talking. But before getting swept up in the hype, I decided to run a real-world test. I spent an entire weekend shooting my Nikon Zf with the 26mm lens locked at f/4, to simulate the kind of shooting limitations I’d face if I switched to the GFX100RF and its native 40mm f/4 setup. This video is part technical, part practical—breaking down not just what works on paper, but how it feels to shoot in low-light, indoor, ambient conditions where fast glass and high ISO headroom matter. If you’ve ever wondered whether full-frame with fast lenses and cleaner high ISO might still be the better tool for your creative workflow—this one’s for you. ⸻ 💡 Key Insights Covered: • Full-frame vs. Medium format: Real-world aperture performance • Why sensor size isn’t the whole story • ISO ceilings, light falloff, and tonal roll-off explained • How to test a camera system before buying it • Why the Nikon Zf + f/1.7 beats GFX100RF + f/4 for my use case • Tips for making the most out of what you already have ⸻ 📸 Gear Used in This Video: • Nikon Zf • NIKKOR Z 26mm f/2.8 (shot at f/4 entire weekend) • Nikon Z 28-400mm f/4–8 • Nikon Z 28-75mm f/2.8 • Step-up ring + Magnetic CPL/VND Filters • Photometer • ARCA Swiss Tripod Plate • Adobe Lightroom + Software Lace for styling • iPhone (BTS / B-roll capture) ⸻ 🔗 Follow My Work: 📷 Website → www.hotshotstudio.com 📸 Instagram → www.instagram.com/hotshotstudio01 🎞 TikTok → www.tiktok.com/@hotshotstudio01 📷 500px → www.500px.com/p/hotshotstudio #FujiGFX100RF #NikonZf #FullFrameVsMediumFormat #GFX100Test #PhotographyGearTest #FStopChallenge #CameraComparison #LowLightPhotography #NikonZSeries #GFX100RFReview #HotShotStudio01 #RealWorldTest #PhotographyTips #GFXAlternative #MirrorlessCameras #CreativeTools
