DZOFILM Pictor Lens Bundle A - White

A parfocal lens maintains focus as you zoom in or out. This means you can change your focal length without losing sharpness on your subject, which is crucial for dynamic shots and efficient shooting.

Focus breathing is the apparent change in field of view when adjusting focus. Minimizing it means the image frame doesn't visibly 'breathe' or expand/contract during focus pulls, resulting in a more professional and less distracting image.

These lenses are designed for Super 35 sensors. While they can be mounted on full-frame cameras (with the appropriate mount adapter), they will exhibit significant vignetting. For full-frame use, you would typically need to shoot in a crop mode or accept heavy cropping in post-production.

The 20-55mm lens covers a wide-angle to a standard zoom range, ideal for establishing shots and general coverage. The 50-125mm lens covers a standard to a telephoto range, perfect for tighter shots, portraits, and bringing distant subjects closer.

The mount is designed to be user-interchangeable. Typically, this involves unscrewing the current mount while supporting the lens, and then screwing on the desired mount until it is secure. Refer to the product manual for detailed instructions.

The lenses feature a 16-blade iris designed to produce a soft, pleasing bokeh. This creates smooth transitions between the in-focus and out-of-focus areas of the image, enhancing subject separation and adding a cinematic quality.

Ensure the EF mount is securely attached. Check camera body contacts for dirt and clean if necessary. Try a different camera body if possible.

This may require professional servicing. Do not attempt to force the ring. Contact DZOFILM support or a qualified repair technician.

Check for any obstructions around the zoom mechanism. Ensure the lens is clean and dry. Extreme temperatures can sometimes affect performance; allow the lens to acclimate.

Confirm you are using the lens on a Super 35 camera or smaller sensor. If using on a full-frame camera, ensure the camera is set to its Super 35 crop mode. Vignetting is expected on larger sensors.
