could think of at that moment..
anyway, if that's the case, it should be looking for a copy without any focusing issues
instead of saying 'u got yourself a sharp copy', 'my lens is not sharp, gotta return it'....
as it is quite misleading which kind of makes ppl think that although it is the same brand
and model but they may not get a good copy.. :x
in addition, focusing issues can be calibrating while an unsharp lens is kind of irreversible
as the glass has already been 'fixed' inside the lens? still kinda new to this but this on my
pls do correct me if i am wrong.. hope u do understand what i am trying to express..
if you are buying a new lens, of course you don't want to go thru the hassle of having to go to service center and have them calibrate and troubleshoot. So pple like to buy a lens that is sharp from the shop. The term sharp is usually refering to able to focus correctly.
Normally checking the physical conditions to ensure there is no physical damage to indicate a drop/impact/shock to the lens. Then check for fungus/scratches/obvious marks/big white elephant on the optical elements. And finally shot near, mid and far to see if the IQ is acceptable. These are what I will do.
You can't imagine how we guys tested our lenses when we shot films. Got LCD and still complain not sharp.
Home is where the heart is.
That's what you call tolerance.
It would be impractical to produce exactly the same product in mass production.
