Great product, Great service
I bought two of these light strips, I had an issue with one I contacted the seller and they shipped out a new set immediately. Great customer service as they stand behind their products.

Q
is this EF to RF adapter and suitble to canon eos r100
A
yes 
Q
How much does the adapter weigh?
A
About 300g,0.66 Ibs. 
Q
I have a canon ae1 camera with alot of lenses will i be able to use those lenses on my canon eos t7 camera?
A
The adapter for a EOS body to a Canon FD manual is the adapter needed. The Canon AE1 uses the FD/FL lens mount. The one I purchased works without a hitch. Mine is a K&F Concept Pro lens mount for Canon FD, FL lenses. From a F1 to a 5D Mark 4 with no issue. 
Q
Will this adapter work with the canon eos-r?
A
no it will not the eos-r has a different mount 
Q
I tried to remove the lens adaptor and it is stuck to my lens. Can anyone help me with this?
A
The adapter clicks on the lens. It has a small dark gray colored lever (not the white plastic tab to change aperture), level to the outer edge of the bottom ring accessible when removed from the camera, grab the whole adapter with your left hand and push the lever in with your thumb, and while pushing, rotate the lens with your right hand to remove it. You need to push in that lever to unlock the lens.
