Re: [APML] Focusing a 500mm telephoto lens



Hi all,
thanks for your replies! I follow the discussion as it goes on: very 
informative and useful.
I'll also look into something like J. Mirtle's method which looks quite 
effective and simple; then buying a KEF will be my second step should I not 
be happy with the first method.

Best regards and Happy Easter,
Emmanuele
