    I take pleasure in turning her knobs, makes her grind and screw her on all the time. After abusing her, I proudly moist her front and wipe her like a baby to keep her clean and spank.

    May I know what do they mean by that? does that mean if i got 2 exact same lens of same
    brand, same model but the IQ I will get from the 2 lenses may still differ? is it like
    buying pokemon booster pack? packaging may be the same but the cards inside are different?
    you rock... link this to pokemon? sharp copy, imo, is one that doesnt have focusing issues and my copy of the lens will render sharp images...

    lol.. this shows that pokemon still exists in the adults world.. jkjk.. just that it is what i
    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
    mind currently..

    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.

    I don't test at every aperture. But if you want, you can spend more time on it.

    u have to compare the whole country stocks that is available to get the sharpest copy that is my advise, because you may get a sharp copy in this shop but who knows, somewhere out there, it lurks an even sharper copy!

    You can't imagine how we guys tested our lenses when we shot films. Got LCD and still complain not sharp.

    That's what you call tolerance.
    It would be impractical to produce exactly the same product in mass production.

    Manual focus lenses no need to test, all sure good. Problems exist only with AF lenses. Never shot an AF lens on film, so I do not know how those guys managed, bless them.
