Fast, Accurate Eye AF and Real-Time Tracking Support
Full compatibility with Sony’s Eye AF and Real-Time Tracking systems ensures precise focus on eyes and faces, even when subjects are moving erratically. The VXD drive’s rapid response and minimal focus breathing make the lens ideal for both portraiture and video interviews. This level of integration matches or exceeds that of Sony G and G Master lenses.
- This allows creators to maintain critical focus on subjects, reducing missed shots and simplifying post-production workflows.
Minimal Focus Breathing for Video Applications
The Tamron 35-100mm F2.8 Di III VXD is engineered to suppress focus breathing, maintaining consistent framing as focus shifts during video recording. This feature is essential for professional video production, where smooth, cinematic focus pulls are required. Compared to previous Tamron zooms, the A078 offers improved performance for hybrid shooters.
- This ensures seamless, distraction-free footage for interviews, documentaries, and narrative filmmaking.
67mm Filter Thread for System Integration
The lens uses a 67mm filter thread, matching other Tamron Di III zooms and primes, allowing for efficient use of ND, polarizer, and variable filters.
