我剛買了支TAMRON18-270.但當我影相後
發現放大了相片後有點蒙.我是用單點對焦的,
請問是機還是鏡問題呢?自己能調較嗎??

會不會是手震而又未開防震呢?

不是.開了.且而是在白天的.不放大看是清.
但放大後蒙了..

用腳架日光好再試罷. 有時兩方面問題都有.

有點蒙:
some of the possible causes
1. back/front focus issue (on cheap Canon bodies, XXXD etc.) --- camera problem
2. lens quality, may be the lens is not sharp at the wide aperature --- lens problem
3. handshake --- human problem, try to shoot with flash, see see whether the same result occurs, if no, then handshake problem
4. object has low contrast or only horizontal pattern but not vertical pattern or vice versa --- camera problem, the design of the AF sensor not accurate
5. u used PL, not CPL and u focus on a reflecting object which fools the AF of the DSLR --- human+camera+filter problem
