Red Dot Mark for Accurate Alignment

Full Manual Control for Precision and Flexibility

Manual control is at the heart of this product. With full manual focusing, aperture priority, and infinity focus, you have the flexibility to adjust your settings precisely. The manual infinity focus allows for precise focus adjustment, especially in scenarios where slight temperature changes might affect the focus.

Infinity Focus Position

The infinity focus position is designed with precision in mind. The position of the infinity mark (∞) on the telephoto or super telephoto lens is shifted slightly to the positive side. This adjustment ensures that you can still achieve accurate focus even when temperature changes cause focus shift.

Moreover, a shifted range is denoted by an L-shaped line, helping you to understand the potential shift range.

Key Tips for Best Results

When shooting at infinity, always check the focus through the viewfinder to ensure optimal clarity and detail. This precaution is crucial for maintaining the precision of your lens at the furthest focus point.

Our product is engineered to meet the highest standards of quality and performance, ensuring that your photography sessions or videography projects are nothing short of perfect.
