Hmm sorry.. i tried looking around..cant find any of these..only able to find advice for buying 2nd hand lenses. Erm..so if i were to buy a new piece from the shop..what should i look out for? Yea..forget about the please bring your camera so to test it out.. and make sure there is no defect and looks new/clean..
I heard members saying about the 3rd party.. lenses sometimes dont have consistent QC..so even if the lens are new..Some can appear to be sharper than the other? Im kinda surprise and worried after reading that line.
So..how do i know the 1 im holding (assume its opened from a brand new box) has passed the QC and is a sharp copy? Since i dont own the lens prevs.. i wont actually know how sharp is sharp or how bad is bad?
Or did i mis-understand the whole thing. If so please enlighten me.. So what about if i only buy lenses from the own big brands..for eg. Canon/Nikon/Sony. Does these brands ensure their QC standards better? Is the (not so sharp/problematic lens) less likely to happen as i believe as long they are of the same kind they should work the same in term of sharpness etc.
Sorry if i seems abit over. As in too worried. So..what do i have to look out exactly to know im buying a good copy?
Thanks for reading. Much appreciated.
