Not CV but the lenses are......
The other day I bought this Sony A7 for Jade and this adapter arrived today....It allows her to use her "L" glass on the Sony.
Sony now seems to be the camera of choice for under 30 somethings.....

I see no need to toss out the "L" glass for stuff that costs more, often weighs more and is larger....and may or may not be much better image wise.

Best, Ben
