coz my el-cheapo siggy 70300 dun haf APO... last time i research wat is it actually..
from my understanding.....
the sensor capture the images in 3 different color RGB.. and each color has its own wavelength..
as it is in wave form... it travel at different speed to reach the sensor...
if ur lens dun haf APO correction... the image later on will looks like all 3 color fall not on the same spot..
easier to notice at newspaper ker... when they print the image different ink doesnt match the previous ink place..
err.... got wat i meant ar bro??
In simple non-technical terms, can just say the color reproduction is not vivid (i.e. quite pale) even if you bump up the saturation to the max. So, anything lens that touches near 300mm length it's best to invest in an APO, otherwise the lens should just stay in the dry box.from my understanding.....
