TuTu_CaR said:Hi guys,
I just realised for my KM 17-35mm lens, alot of times, the photos come out, my subjects are OOF. the ones in focus are those things are at the back...
is this lens suffering from the so called back-focus problem?
how to remedy? how to confirm?
TuTu_CaR said:my 24-105 and 50mm no problem
100mm marco only use MF so dunno
this 17-35 seems to make my foucsing very difficult..
during wedding table shots have to use MF to be certain
during candid shots, this lens always seem OOF
even though the camera show the focus dot and i focus locked onto the subject....
think i try on a ruler.... if really got problem how?
TuTu_CaR said:hmmmm
okok
i try 2molo night again....
i tot even at F2.8...the point i focus on should be sharp....
then the one at the back should be blur......
nvm i try again loh

tokrot said:yes, i did almost the same test and had the same results last time. I thought it was the lens prob until I read some one mentioned tricky focusing with wide angle. I think it's quite normal for wide angle. You can set aperture to f4 ( in my case) and above to correct the OOF problem (to increase DOF). Correct me if I am wrong.![]()
