DZOFILM Pictor 50-125mm T2.8 Lens - PL Mount and EF Mount

No, the DZOFILM Pictor 50-125mm T2.8 is a manual cinema lens designed for manual focus and zoom control. It does not support autofocus.

A parfocal lens maintains focus throughout its zoom range. This means you can zoom in or out without needing to re-rack focus, which is crucial for many cinematic applications.

T2.8 refers to the maximum aperture of the lens, indicating the amount of light it can transmit. 'T' stands for transmission, which is a more accurate measure of light throughput than 'f-stop' for cinema lenses.

The lens features 16 T2.8 iris blades, which help create a smooth and circular bokeh. To achieve softer bokeh, use a wider aperture (lower T-stop number) and ensure your subject is sufficiently separated from the background.

This lens is designed for PL and EF mounts. You would need a compatible PL-to-E mount or EF-to-E mount adapter, but ensure the adapter supports the necessary physical clearance and does not introduce optical compromises.

The minimum focusing distance for this lens is 0.4 meters (approximately 1.3 feet), allowing you to get relatively close to your subject for detailed shots.

The DZOFILM Pictor 50-125mm T2.8 lens weighs approximately 1.6kg (around 3.5 lbs).

Ensure you are using the correct mount (PL or EF) for your camera and that the camera's mount is clean and free of debris. Check that the lens mount locking mechanism is fully engaged.

Verify that the lens is set to its parfocal mode. Ensure there is no focus breathing compensation active if your camera system offers it, as this lens is designed to be parfocal out-of-the-box. Check for any physical obstruction or damage to the zoom or focus mechanisms.

Check if the aperture control is freely moving. Ensure no external force is applied to the aperture ring. If the issue persists, it may require professional service.

Confirm the lens is clean. Ensure the focus is accurately set. Check camera settings for sharpness and contrast, as these can also affect image appearance.
