As a newbie here, i still dun understand calibration. As i google, calibration needed when there is focus issue.
So is all lens sold come with free calibration? i call up a shop to ask for pricing and term and condition, for tokina , there is free 2 time calibration, for Tamron, there is nil, when i ask why, , was told tokina got problem so got free calibration.
So why is it so? if tokina got calibration issue, is it a product of lower quality. From i google, tokina is better than Tamron, yet it dun have calibration issue?
mine is nikon, so fro nikon lens, is there calibration issue, and if needed, need to pay too if under warranty?
please enlighten me. thanks
