Related Questions and Answers
Q: 1. Is there any advantage to using PL over EF mount for use on a Canon C500 mkii?
A: PL tends to be a stronger locking connection over EF. Also, the Canon C500 camera has a PL mount version that may require you to work with PL lenses.
Q: 2. I'm impressed with this lens but how do I get more contrast out of it? and more color? It's rather plain-looking. Filters?
A: The IRIX 150mm T3.0 Macro 1:1 Cine Lens (Canon EF, Feet) is neutral in color and has good contrast generally speaking. You can add color filters to the lens or in post. You can shoot more contrasty lighting or add contrast in post.
Q: 3. Would it be better if I use the ef-mount version on a mft sensor camera (gh5) with a speed boost or would it better to use mft version of this lens?
A: it is always better to use the native version of the lens.
Q: 4. does this lens work with the Canon 5d mk iv autofocus?
A: This is a manual focus cinema lens. it does not auto focus.
Q: 5. I want to mount this lens on my PL-mount ZCAM camera and on my EF-mount Blackmagic 6K Pro. Which adapter ring is best?
A: There are two options that would allow you to mount a PL lens like the IRIX 45mm T1.5 Cine Lens to your Black Magic Pocket 6K Pro. The best option is from Wooden ( BH #WO274700) which would convert your P6K to a PL mount camera. Also there are PL to EF adapters ( BH #FOPCEAAP ) that could also be an option. Please note that the IRIX lens has not been tested with the FotodioX PL to EF adapter.
Q: 6. Can I use this lens for still photography as well, switching back and forth from video applications?
A: While this is a manual focus cinema lens you can still use it for photography.
Q: 7. can i use this on my black magic pocket 6k?
A: Yes you can.
Q: 8. Is the lens mount user-swappable?
A: This lens is not user-swappable. I recommend going to Duclos Lenses for professional mount conversion and calibration. They offer the IRIX lenses in ARRI PL, Canon EF/RF, L-Mount, Micro 4/3, Nikon Z, and Sony E mounts.
Q: 9. Will Irix release L, Z, and RF mount lenses in their regular photography line of lenses?
A: We have not heard of any imminent plans for those particular lens mount options.
Q: 10. Is this considered a FF lens? So on a S35 chip the focal length would be 1.5x magnification?
A: Yes, the IRIX 45mm T1.5 Cine Lens covers full frame sensors. There will be a 1.5x crop factor when using this lens on cameras with a Super35 sensor.
