Video test with the tricked f/3.5 limitation for autofocus.

A99 A77 A57 Autofocus “hack” to get around the F/3.5 limitation for autofocus. Use at your own risk! from Shawn C. on Vimeo.

Shawn (Click here) made this video to proof how the aperture limitation removal trick from Portreti is working. There are some limitations with the hack:
1. Your lens will be wide open all the time. You cannot stop down at all. If your lens is soft wide open, you might be better off manually focusing.
2. Leaving the spring stretched out could damage your lens over time.
3. Be careful when you do this.

Thanks Shawn and Portreti!
