Autofocus lenses and cine lenses are both types of camera lenses, but they have some key differences:
Autofocus lenses are designed for still photography and are optimized for quick and accurate focusing. They typically use a motor to adjust the focus and are controlled by the camera’s autofocus system. They are faster, more accurate and less noisy than manual focus lenses.
Cine lenses are designed for motion picture and video production, and are optimized for smooth and precise focus and aperture adjustments. They typically use manual focus and aperture rings that are geared for smooth operation and accurate control, which is important for video work where focus pulling is common. Cine lenses are also built with a consistent aperture, which means the size of the aperture stays the same throughout the zoom range. Other factors include minimised focus breathing which is common with compact auto focus lenses.
Build quality: Cine lenses are typically built to higher standards than autofocus lenses. Cine lenses are designed to withstand the rigors of professional use, whereas autofocus lenses are designed for consumer and prosumer use.
Size and weight: Cine lenses tend to be larger and heavier than autofocus lenses. This is due to the fact that they are built to higher standards, and use more metal and glass in their construction.
Compatibility: Autofocus lenses are typically designed to be used with specific camera mounts, whereas cine lenses are designed to be used with a variety of camera mounts, as well as with manual follow focus systems, which allows for more flexibility.
Price: Cine lenses tend to be more expensive than autofocus lenses, due to the higher quality components and construction.
It’s important to note that, cine lenses are a great choice for professional videographers and filmmakers, but autofocus lenses are more suited for still photography and amateur videographers.
