I have no medical opinions, but my eyesight definitely isn't what it used to be either. I mostly use the 4x5 now because I am doing personal projects, but when I use my Leica, basically, I am focusing by "best estimate" - that is, a lot of time I do not see a perfect aligned image any more, but it's still easy to say "OK, this is clearly really off, and if I crank this way it is also clearly off, therefore, while somewhere in the middle here looks bad to me still, it must be the in-focus because it is the best of the bad" And usually I still nail focus that way, even at 1.4 Good luck On Sat, Aug 27, 2016 at 1:56 PM, Rei Shinozuka <shino at panix.com> wrote: > > > First, "Hi" to the LUG and the many friends I've met here.
