particles inside new lens acceptable?
Recently indented a new sigma wide lens and upon inspection found >4 big visible particles inside lens elements. Rejected the lens and request another new one.
Question is, what if the next new lens also have particles inside? Am I being to criticle if I keep rejecting the lens until a particle free lens is given to me?
I know optically, the image will not be much affected by the particle.

CP did a 1 to 1 xchange.
this time round,
my 2 kids were with me,
so guy from CP check for me.
look straight into the lights n say ok.
sad that i trusted his method.
reached n used my method n found A LOT OF LITTLE SPECKS!
now lens with canon for 5 days n still waiting.
shame on canon n CP in this instance.

I think the 50mm f1.8 gets dust in easily. However, I don't think image quality is affected, unless they are really huge!
