17.2 we are registered in the state of colorado. ∞ pos : the rail position where the focus would be set to infinity. it’s not even a choice, you have to go through all the options anyway! it’s fairly easy to do because the texture is so soft. if this position is lower than the upper limit then it’s value becomes blue. my sense of timing is legendary. unfortunately, too many don’t realize there is a real reason behind these rules until it is too late. there is no way on earth that i am going to part with $439 for a version upgrade.
