What We Like
+Sharp image quality throughout the image circle at f/4 with excellent optical design
+Dual STM autofocus system operates smoothly and quietly with good AF speed
+Extremely compact and lightweight at 130g, ideal for handheld VR shooting
+Affordable entry point for stereoscopic 3D content creation compared to professional alternatives
+11.8mm baseline length mimics human eye spacing for natural parallax and immersive VR effects
+Works seamlessly with Apple Vision Pro and Meta Quest 3 for 3D/spatial content playback
Worth Knowing
−No optical image stabilization; relies on camera body IBIS for stabilization
−Currently limited camera compatibility (primarily EOS R7, with R50 V support)
−No weather sealing, limiting outdoor durability in challenging conditions
−Servo autofocus not supported; focusing must be completed before recording starts
