Which camera systems is this lens compatible with?

What is a parfocal lens?
A parfocal lens maintains focus while zooming. This means you can zoom in or out without the image losing sharpness, which is crucial for cinematic shooting.
How does the 16-blade iris contribute to image quality?
The 16-blade iris creates a more rounded and aesthetically pleasing bokeh (out-of-focus areas), providing a smoother transition and avoiding harsh polygonal shapes.
Troubleshooting
Lens not mounting correctly
Verify that the lens mount type (Sony E-Mount) matches your camera body. Ensure no obstructions are present on the mount of the camera or lens. Align the red dots and twist gently until it locks.
Focus is not sharp at certain focal lengths
Confirm the lens is a parfocal lens and that you are not experiencing focus breathing issues. Ensure the camera's autofocus settings are not interfering if using AF. Manual focus should remain consistent when zooming.
Bokeh appears irregular
The iris has 16 blades for rounded bokeh. Irregularities might occur at very small apertures or with strong out-of-focus highlights. Ensure the aperture is set appropriately for the desired bokeh effect.
Filter slots are difficult to use
Ensure you are using filters specifically designed for the rear slot or the 77mm front thread. Handle filters gently and ensure they are seated correctly without forcing them.
