## Questions & Answers

**Q: Will this adaptor work with a canon rebel t1i using your 420-800mm zoom lens?**
A: Yes, this T mount to C works with Canon rebel t1i using our 420-800mm zoom lens

**Q: Has anyone had an issue with locking this into the camera?**
A: YES! DOESNT LOCK INTO PLACE! Worthless!

**Q: Is the size of the other end of the adpter (i.e. not the camera connected end) always the same for with T2 adapters?**
A: The T-mount lens mount is a male 42mm .75mm thread pitch screw mount with a 55mm flange focal distance.  It was introduced by Tamron, hence "T" mount, about 1957.  Other manufacturers used the standard.  Soligor called theirs the "T2" mount. As far as I know all "T-mount" lenses fit all properly made "T-Mount adapters".  After around 1962 the standard was changed to a conical thread, but I've never found a T-mount lens that didn't fit any T-mount camera or T-mount adapter that I had.

**Q: Will this fit rebel t3 to adapt to samsung 50-200mm lens?**
A: The purpose of this particular adapter is to connect a T-mount (a 42mm .74mm pitch thread screw mount with a 55mm flange focal distance) manual lens to a Canon EOS camera.  I am unaware that Samsung ever made their 50-200mm lens in a T-mount version but if they did it will work.
