Related Questions and Answers

Q: 1. Is this adapter compatible with any other model PL lenses?

A: The Venus Optics Laowa 0.7x Focal Reducer for Probe Lens (PL to X Mount) is designed particularly for the Venus Optics Laowa 24mm f/14 Probe Lens (ARRI PL, Cine-Mod Version), and it is not guaranteed the quality and fitment will retain if using third party PL lenses.

Q: 2. Is the Sony HDVF-EL20 compatible with the Sony HSC-100R? Is it the same as discontinued HDVF-20A?

A: The Sony HDVF-EL20 4k viewfinder will work with the Sony HSC-100R. The HDVF-EL20 is a full color OLED viewfinder, and the HDVF-20A was Black and white and HD only.

Q: 3. Does it work with the periprobe lens?

Q: 4. Would this work with the Atlas Orion?

A: I tis not known if the Venus Optics Laowa 1.4x Full-Frame Expander (PL to PL) works with Atlas Orion Series lenses. One check you can do is use this simple gauge. If the lens' rear element clears this gauge, it is likely the lens will work. Only testing will tell for sure.

Q: 5. Will it work on the Canon 8-64mm T2.4?

A: The Venus Optics Laowa 1.4x Full-Frame Expander (PL to PL) is only intended for use with the Laowa OOOM 25-100mm T2.9. The Canon 8-64mm T2.4 s16 lens would likely not work with it. Even if it could mount, there would be significant vignetting as the adapter is meant for a super 35 lens.

Q: 6. Will this work with the nanomorph lenses as well? Is there a measurement for the max flange depth that will work with this?

A: The Venus Optics Laowa 0.7x Focal Reducer for Probe Lens (PL to MFT Mount) is optimized for the probe lens, so it can’t be used with the Nanomorph Lens.

Q: 7. What other lenses may work with the focal reducer (PL to RF)?

A: The Venus Optics Laowa 0.7x Focal Reducer for Probe Lens (PL to R Mount) (B&H# VE07FRPL2R) is a highly specialized focal reducer designed to fit and work well only with the Venus Optics Laowa 24mm f/14 Probe Lens for ARRI PL (Cine-Mod Version) (B&H# VE2414PL). While it's possible that you may get it to work to your satisfaction with other lenses, we cannot endorse their use as damage to the optical element in the focal reducer could result. The major concern has to do with an invasive rear element in the PL lens coming in contact with the element in the focal reducer. Moreover, even if one could be sure of the fit, the result may suffer from more softening or chromatic aberration than some customers would consider acceptable. As is often the case, however, you are welcome to try the focal reducer and to return it within 30 days with an RMA authorization and accompanied by all of the original packaging. It would also need to be in the same condition in which it was received. Returns policy details: https://bhpho.to/3utL5n1
