Since I have turned 50, my near range vision is no longer any good and I need reading glasses or bifocals now for reading, but fortunately my infinity vision (which is what a camera finder requires) is still 20-20 so I dont have any problem MF focusing even without glasses at this point.

Maybe I need to start setting aside some money for a future Lasik procedure. I truly dread the day when my eyeballs finally betray me.

Forty years ago I could manual focus any lens, every time. I could even pull focus on a car moving toward me. But eyes wear out faster than old manual lenses.
