CameraBeta had the opportunity to speak with YONGNUO’s R&D staff about this lens and they told:
- Designing a zoom lens is difficult.
- Zoom lens manufacturing requires stricter precision, and even the slightest deviation can lead to deterioration in image quality.
- Coating is also important as it also affects backlight resistance.
- The 12-31mm has a minimum focusing distance of 13mm, and the 32-35mm has a minimum focusing distance of 50cm.
- Correcting distortion was difficult, but it is corrected by the body.
