⚠️Reminder ！TTL Flash with Auto Exposure, NO HSS Funtion: The IT20 supports TTL (Through-The-Lens) metering, allowing for automatic flash output adjustment based on the scene's lighting, making exposure faster and more accurate. However, please NOTE:This flash does not support High-Speed Sync (HSS). To ensure proper flash synchronization, we recommend using a shutter speed of 1/160s or slower. ⚠️Lens Barrel Shadows Notice: The Godox IT20 is designed with portability in mind and is best paired with short focal length lenses. Using telephoto or large lenses may cause lens barrel shadows in your photos.To avoid this, we recommend adding the Godox TTL Hot Shoe Riser(Sold Separately), which raises the flash by 30mm for better clearance and Keeps TTL function. It also tilts 0–90°, making it easier to use direct or bounce flash. Ultra-Compact TTL Flash: The iT20 offers fully automatic TTL exposure metering in a compact form factor—just 1.6 x 1.6 x 1.3 inches and 1.6 oz, perfect for creators who want powerful lighting on the go. Manual & TTL Dual Mode with Quick Switch: Switch effortlessly between TTL and Manual modes using the dedicated M/TTL button. Fine-tune your lighting with six output levels (1/32 to 1/1), adjustable in ±⅓ stop increments for precise exposure control. Built-In Rechargeable Battery with Fast Recycle: Equipped with a built-in USB-C rechargeable lithium battery, the iT20 S delivers up to 700 full-power pops and features a 1.5s recycle time—with full recharge in just about one hour.
