When I first started shooting LF again, after an absence of more than 15
years, I thought this lens was discouragingly unsharp.  I'd hold a print up
close, and the definition just wasn't what I recalled from my old kit.  Then
I held the print out at arm's length one day -- whoa! That's better! I
hadn't realized that my glasses (only acquired about eight years ago) don't
allow critical focusing at 10 inches, the way my plain eyeballs did back
when I was in my twenties andthirties. This aging thing really bites :}

It's amazing what can be accomplished with just pencils and paper, given
enough determination and patience.
