You weren't wearing your glasses in real life. That might explain the (apparent) bad performance of the lens compared to simulations? /jk

My dad is giving photography lessons, and one of the constants are people realizing during session one that they, in fact, do need glasses when the autofocus does not agree with their eyes.

When I borrow my dads camera for the odd shot at times, I totally relly on AF, if I went by the view finder I am almost blind... Same thing the other way round!

Sounds like you need to adjust the viewfinder diopter.

[hef19898]

Yeah, we did! Using the other person's viewfinder on the other hand... Well, I trust AF in those cases!

That's the advantage of an electronic viewfinder :)
