Canon Speedlite 600EX-RT. This strobe is a high-performance flagship model made by Canon, used even in professional settings. Regarding its condition, as described in the operational checks below, the strobe functions can be used, but there are two issues. Please purchase only if you understand that it is a "for parts" item. If you use it wirelessly without frequently turning it on and off, the impact should be minimal. ◾️Reasons for being "for parts"◾️ ・The power button is faulty and doesn't stay in place. It won't turn off even when set to off, so you'll need to remove the battery cover and disconnect the battery contacts to turn it off. (Image 11) ・The rubber on the contact part is deformed, and it won't connect unless pressed in. (Image 8) ◾️Operational Checks◾️ ・Flash OK (Light output adjustment confirmed) ・Zoom operation OK ・Wireless flash OK ・Wide panel and catch light panel operation OK ・Power button: As mentioned above, there is a problem. ・There is a rattling sound inside the strobe, but it doesn't particularly affect its use. ■Included Items ・Strobe body (Batteries not included) ・Original case ◾️Specifications◾️ ・Maximum Guide Number: (ISO100) 60 (at 200mm zoom) ・Zoom Range: 20-200 mm I have many Canon products for sale; bulk purchases are welcome! ↓↓ #sara's Canon product list -------------------------------------------------- Canon SPEEDLITE 600EX-RT 【For parts】
