A third-party extender would be needed as the Canon models only connect to Canon L models, and not even all L-lenses. You might want to identify the specific lens and extender your considering along with the camera model. You may find there's no technical options for many camera, lens, extender configurations, assuming you desire to maintain auto-focus functionality.

There has not been a tele extender made that improves image quality. Image quality is already degraded for a non-L lens, it just get worse with a tele extender.

Extenders work fine in certain situations. I use a 1.4x extender when shooting sports at times when I need the extra reach using a Canon 70-200f4 lens. It works great, yes you will get some degradation but not that much. The 2X converter forget it, sold mine results were terrible. If using a Canon lens use a Canon Converter, Tamron use a Tamron converter for the best results.
