Video Description

In this follow-up video, I revisit the autofocus performance on the Blackmagic Cinema Camera 6K Full Frame — but this time with a twist. When Blackmagic first introduced continuous autofocus, I tested it using the Sigma MC-21 EF-to-L mount adapter and a Sigma EF 24–35mm lens. The results were far from impressive. But after switching to a native Sigma 28–45mm f/1.8 L-mount lens, everything changed. ✅ Face tracking now works ✅ Focus holds steady during movement ✅ Usable in professional studio and YouTube setups (with the right accessories) 👉 Subscribe if you want more deep dives, camera tests, and filmmaking tips! #Blackmagic #CinemaCamera6K #AutofocusTest #CameraReview Tech discussed in today's video ( links are affiliated and help with the content creation for this channel): Blackmagic Cinema Camera 6K: https://bhpho.to/3V77ELO https://amzn.to/4bLIecg Sigma 28-45mm f/1.8 DG DN Art Lens (Leica L): https://bhpho.to/4cWUs1Z https://amzn.to/462rJa6 The battery grip I use: https://amzn.to/4iTbWji Sigma 28-45mm f/1.8 DG DN Art Lens (Leica L): https://bhpho.to/4cWUs1Z https://amzn.to/462rJa6 The ND Filter I use: https://amzn.to/3LokyiN My Studio A Camera: https://amzn.to/3SEYlBc My A Cam Lens: https://amzn.to/4dQbz6r The Key Light I Use: https://amzn.to/3WRZl7j The Softbox I use: https://amzn.to/3T1BVuf As an Amazon Associate, I earn from qualifying purchases.
