I've got a record player. On that record player, I can flip a switch from 33 to 45 rpm. There's also a dial where I can fine-tune the pitch by making the record spin slightly faster or slower. That's how I see the firmware crap on lenses. If you don't need to adjust it, that's fine, but, if you know what you're doing, you can tweak it however you want/need. I personally don't have any auto-focus lenses because I don't shoot anything where autofocus has a distinctive advantage over manual focusing, other than being a bit faster. I don't hate technology in my stuff, generally, unless it starts interfering with what I want or telling me "No, this is what you want"
