After I asked you about the extender fitting on the Canon ef70-300 f/4-5.6L, I went to the Canon site and they say the extender will not work on this lens. I am interested if the extender will work but do not want to damage the lens
Red, I remember reading that people were using that combo so I looked it up. You’re right, it’s not recomented. They were only using it at the longer ranges because at shorter focul lenghs it does make contact. They were using it with a hose clamp to keep it from zoning into the short focul length. Sorry about that!!
