Hi all!
I have lurked here for a good while, but now I have a question the internet has not been able to answer.
I have a chance at a sigma 500mm f4.5 apo from the year 1990. it is for CANON EF mount, BUT it is for film cameras only- thus it is VERY cheap and supposedly useless. There are adapters for EF to NEX that supposedly will control canon's electronically controlled aperture, but here's the stump. will these adapters work with a "film only" AF lens? I do not care abour AF working, as the NEX focus peaking is fabulous... but that darn aperture needs to work. I may just need to buy the lens and a adapter and see, cause I am dying to see if it works.
example of the lens

So yeah I hope I can figure this out!!
