I don't remember who sang the song originally (Fred & Ginger, Bing?),
but my mother, an eternal optimist, used to hum it even amidst
thunderstorms and tornados. And it's about that time of year when
I start humming it again too as the nights get clearer, colder, and
brighter for astrophotography.
But even if you don't know the song or can't even hum with waxpaper
taped on a comb, you can still get the picture right with a Series IV 'Stiletto' focuser. The new Series IV will get your camera in perfect focus in a matter of seconds. (And those seconds can be precious when it feels like your knuckles are freezing off.)
The Series IV uses precision ronchi gratings calibrated to the exact
backfocus or film plane distance of your camera. It's easy to use and
does away with all the guesswork in focusing. And it will work with
any model camera you have (CCD, 35mm, MF, or Video) or any camera you
will come to have. It's upgradeable, and interchangeable mounts are
available for just about all cameras. And since the Series IV comes
precalibrated, no fiddling is necessary on your part.
