Does the Askar FRA300 have back focus requirements
Hi all,
Looking at pulling the trigger on an Askar FRA300 but am confused by what I’ve read regarding back focus.
I’ve read that because it’s a Petzval design back focus isn’t an issue and you don’t have to worry about it.
On another site it lists the back focus at 71mm, implying it is something you have to cater for.
Any one have any idea which it is?
