Overview
The Apex 1.33x Auto-Focus is an anamorphic lens series from manufacturer Blazar Lens, marketed by Blazar as the world's first anamorphic lens with autofocus. Anamorphic lenses horizontally compress the image, allowing a wider field of view to be captured on a regular sensor and de-squeezed to widescreen in post-production; this creates the characteristic oval bokeh shapes and horizontal flares typical of the look.
The series is aimed at mirrorless cameras with S35/APS-C sensors. The comparatively moderate squeeze factor of 1.33x is a deliberate design decision: according to the manufacturer, stronger anamorphic compression makes autofocus systems more difficult to function, which is why Blazar opted for 1.33x for the AF series.
Technical Specifications
At launch, the series includes two focal lengths (35 mm and 50 mm). Both share the following key data:

Further features according to the manufacturer:
- Focus ring in cinema standard 0.8 (Mod 0.8) with 180° rotation, suitable for follow focus units
- Focus-by-wire system with seamless switching between autofocus and manual focus (AF/MF)
- Real-time tracking and eye-tracking via the camera's AF system
- Low focus breathing (manufacturer specification below approx. 1.5%)
Mount Options
The lenses are offered for several mirrorless mounts. Confirmed mounts include Sony E and Leica/L-Mount (including Panasonic Lumix, Blackmagic); depending on the market, the manufacturer also lists Nikon Z, FUJIFILM X, and Canon RF.
On-Set Use
The Apex AF is aimed at productions that want to combine the anamorphic widescreen look with the speed of autofocus – for example, small crews, documentary and run-and-gun situations, or solo operators. The combination of AF with eye-tracking and continuous focus is not available with classic, purely manual anamorphic lenses and replaces a separate focus puller in these scenarios. For classic narrative work with focus assistance, the cinema-standard manual focus ring is available in parallel.
