Hello all,
I just purchased the above lens from John 3:16 at funan today and noted some "issues" with it and need to clarify with experts here if this is normal.
1. I had a problem getting the focusing to be sharp. I tried doing a simple portrait of my wife and concentrating on her eyes and even when using a tripod with my 350D mirror lock, i couldn't get the photo to be really sharp (every photo with f1.8). Tried to focus on some text printed on the canon box and nope, doesn't seem to be sharper than the lens kit that came with the camera. I tried mf instead and photo was noticeably sharper. tried auto focusing on some other text on a piece of paper lying on the table and noted that the text where i focus did not appear sharper than the text that were nearer towards me. tried many many times with f1.8 on various subject with tripod and proper lighting.. sometimes can focus sharply but mostly not as good as when i use mf. is there anything wrong or is this wat i should expect from a sub 100 bucks lens?
2. There is a very noticeable 1mm dust or scratch mark IN the lens..not on the front or back glass surface but on some glass element within the lens. The mark is noticeable for even a newbie like me to point out after careful looking at the lens. is this normal for this lens?
what would u do if u r in my situation?
thank you very much
