缺點:
-u can see the inside part of the lens when u shift it to farest left or right, unacceptable design
-light sensor cannot sense properly after u when u shifting or titling the lens
-should be largest apertune 2.8 as this price
-price very expensive
評價:
i think this lens is for patient photographer, not active person.
should be always together with the tripod abt this lens
and this one on 5D is too wide, for 1.6 is much better
45mm that one is better for FF, ex: modeling, landscape ,macro......
nice lens , i give 4 star becoz the price is too high.
