The Venus Optics LAOWA 24mm T14-40 Full Frame 2x PeriProbe Cine Lens captures sharp magnified shots with full frame camera sensors using their Canon RF-mount and has a focal length of 24mm. Its periscope-style lens tube with interchangeable ends features an aperture range of T14 to T40 for a deep or shallow depth of field. Use it underwater or in tight spaces, thanks to its waterproof front barrel and slim profile. A lens construction of 28 elements in 19 groups creates a smooth, circular bokeh with minimal focus breathing. The lens can rotate 360° along the axis to unlock the orientation ring and create spinning shots. Both the focus and iris rings have 0.8 MOD cinema-standard gears for intuitive manual controls. A 1/4"-20 thread at the end of the 15.7" lens allows you to mount fill lights or other accessories. Built-in LEDs in the lens tips provide a ring-light effect to your shots.
