It may take a bit of looking, but there are adapters that actually screw on to the front of the lens, like a filter ring and then allow you to reverse the lens and bayonet it into your camera body. You, of course, lose the AF and metering data... and also
trust your lens' filter threads to support and hold the relatively massive weight of the lens.
Blessed are the those who have faith... because if you do this with a good-sized zoom... you will need it.

TIMBER!!!
