question
For the Sony a6500, what is the exact crop factor after using this sped booster? Id like to know exact (or close approximations) in reference to 35mm, so I can purchase lenses accordingly.
The resulting crop factor is 0.89. To make things easier as you go forward in your photography, forget crop factor and just know the mm for wide, medium and tele for each sensor size you are using. The Sony a6500 has a APS-C sized sensor so for it: 18mm=wide, 32mm=medium, 65mm tele. Think this way and you will not have to calculate the FOV (Field Of View) of a sensor you are not using.

You dont need an adapter to use Full Frame E-Mount glass on a a6500. This adapter is only for EF Mount glass.

No, you can't adapt Sony E-Mount lenses onto a Canon EF-Mount because physically, the flange distances are not compatible with adapters.
