Does your Mount work with EF-S lenses as well as Other 3rd party Canon compatible lenses like Sigma and Tokina?
Yes the Mount works with any EF and EF-S lens that is Canon compatible. We have tested several Sigma lens and have had no problems. We havent had a chance to test any Tokina lenses yet but I assume as long as they are following the Canon lens protocol properly there shouldnt be any problem. I will post an update to this faq as soon as we can test a Tokina Lens. 3.
