About this item
  • 【Important Usage Notes】⚠ This is a fully manual lens with no electronic contacts. After attaching the lens, switch your camera to ​Manual (M) mode​ to avoid "no lens" errors. If the error persists, enable ​​"Release shutter without lens"​​ in your camera menu (commonly found on Nikon/Sony models).
  • 【Professional Manual Focus Experience】Ideal for enthusiasts who enjoy full creative control. This 420-800mm f/8.3 lens requires manual adjustment of shutter speed, ISO, and focus – helping refine your photography skills and unlock artistic potential through a hands-on approach.
  • 【Super Telephoto Zoom Performance】A specialised full-frame zoom lens with a adapter ring. Features include precise manual focusing with a large focus ring, internal focus mechanism, and UMC multi-coating to reduce flare and aberrations. Aperture automatically adjusts with focal length (f/8.3 at 420mm to f/16 at 800mm). Accepts 62mm filters.
  • 【Compatible with Canon EF/EF-S Mount】Works with a wide range of Canon DSLRs including: Rebel series: T8i, T7i, T7, T6, T5i, T4i, T3i, SL3, SL2, etc. EOS models: 90D, 80D, 77D, 6D Mark II, 6D, 5D Mark IV, 5D Mark III, and others.
  • 【Ideal for Distant Subject Photography】Perfect for capturing the moon, wildlife, birds, architecture, aircraft, and landscapes. Note: As a manual lens, the aperture is not set by the camera and may display as "F--" or "F00" – this is normal.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
