Hi all brother and sister and friends,
Need yr help,I am attach 4 pictures take by two different lens (Canon 28mm-135mm f3.5-5.6 USM IS and Simga 17mm-35mm f2.8-4.0 EX HSM lens).
Using same setting at f4.0 ,Shutter speed 1/20,ISO 200,without flash and mount on tripod.
I personnal found that using Simga lens,the picture is blur and soft compare to Canon lens at the same distance (35mm).
My main worry is anythings fautly to my Simga lens and the picture is out of focue point.
Any comment and advise are most welcome.
Thanks and Regards
