## Questions & Answers

**Q: What, exactly, is the difference between the $99 vers and the $199 vers?**
A: the one with ring allows you to assign another function to the ring.  e.g. exposure compensation.  Giving you extra flexibility.

**Q: Does this adapter affect autofocus of the R series cameras under challenging conditions--like a bird in flight against busy background?**
A: The adapter has no glass, its main function is to set the proper distance between the sensor and the EF lens.

**Q: will this adapter work with  sigma 18-35mm f1.8 art dc hsm lens for canon and will work with sigma 30mm f1.4 contemporary dc dn lens for sony e ?**
A: This adapter should work with the sigma 18-35mm for Canon EF mount but the image won't cover all of a full-frame sensor because DC lenses are made for smaller APS-C sized sensors. You can enable crop mode in your EOS R camera to only use part of the sensor.

No, this adapter is not for Sony mount lenses.

**Q: Add doesn't mention rf...it just says r-type which is confusing. that's not the standard term. so this product allows me to attach ef to my r5?**
A: Yes this lets you mount EF lenses to R Series Cameras like the R5.
