Anyone know of a source for the USAF Optical Test chart? Something in the $20.0 0 range? Edmund Scientific has apparently stopped carrying it. Least that's wh at the gal on the phone said today.

You can download David Jacobson's approximation: http://www.cs.berkeley.edu/~qtluong/photography/35mm/usaf If you have software which understands postscript you can print the chart yourself. Otherwise I would be happy to put the printout in the mail for you.

Thanks a BUNCH!

Additionally, somehow or other Bob Atkins accessed a catalog citation for it on-line at Edmunds and I placed an order. We'll see if I get it. When I go to their on-line catalog it indicates that that portion is under construction. Whatever.

But Thanks a lot Tuan - if they drop the ball I will have your pdf version which I've printed out.

Hi Sean, Edmund Scientific sells it (about 40inx30in).

Hey Alan!

Thanks, got it Thursday from Edmund in the mail. Don't know why but I couldn't access it on their webpage. Bob Atkins got me a link and I ordered it Monday, I think it was.
