Although I "like" autofocus lenses, I'm just not comfortable with them.

They don't always focus the way I want. They don't always focus at the same thing I am looking at. They don't always decide on what is in focus or out of focus the way I decide.

Much of the time an autofocus lens can be helpful but I find that, just as much of the time, I have to figure out some way to trick the lens into focusing the way I want it to. This programmable lens seems like a neat idea but, to be honest, it just seems like another thing I'd have to learn how to trick into working the way I want it to. A lot more expensive and time consuming, too.

To be honest, I'd rather just turn a dial or twist a ring until I get things to look the way I want them to. :|
