Does anyone know where i can get a Siemens Star Chart for Back Focus Adjustment?
I am putting a lens on my new camera for the first time.
How big does the chart need to be?

Heh, I had to look up what that was. :blush:
B&H sell several:
(Ignore the obvious "star maps" for star-gazing)

Thanks! boy those are pricey.. but i guess if you change lenses alot it might be worth the investment.
