Hi,
I've just picked copy of sigma 70-200 apo dg ex f2.8 lens but I'm experiencing front focus at 200mm wide (a little)and back focus at 70 wide (quite alot)
I've used the k10d debug menu to resolve the BF issue with my fa 50 1.4 but how can you resolve front and back focus issues within the same lens?
Is it more likely a camera or lens issue? both are out of warranty but if the
lens is faulty I should be able to return it.
Anyone come across having front and back focus issues on the same lens? if so what did you do to fix it?
Any pointers would be most gratefully received
Cheers
Steve
