problem with my 24 1.4 II L Lens
May 2, 2012

Hello guys, I dont normally post here, but knowing you are all experts makes me want too,

Ive been having a problem with my new lens, I didn't think I had this problem so bad until recently, now it's maybe my own paranoia, or I do have a problem, i'm not sure what to think really, I own a 5D Mark2 and my lens a Canon 24 1.4 II L Lens, I'm finding at 1.4 I have to take 5 or 6 images to achieve focus that in the hope 1 will have achieved good focus, I understand 1.4 is so shallow its going to be tough anyway and on a poor AF camera as the 5D2 i'm going to have problems, but I think this is just 2 soft, and allot of the time, the camera misses completely, I just don't get it, after spending so much money, i'm getting a but sick of Canon, and I maybe to blame, Now I use a center spot focus and lock and recompose, and this may be a problem, or not, I do think the camera used to lock focus better, is it possible a camera over time, lose focus, I have tried front and back focus tests on a tape measure, and the focus seems fine, I know I should stop down the lens slightly, but I don't see why I can get a semi sharp image at the right distance on 1.4, for that money I think you should be able too, last week, I took a picture of a friend at the side of his hair just on a grey bit above his ear, and it missed so much and I achieved focus on his forehead, I did more tests and the camera could not focus on hair, even though it was a good contrast for the camera, so I though maybe there's certain things canon sensors have trouble with, so today, I went for a walk with mum, to a forest to see the bluebells, it was a bad day, and nothing great to photograph, so I took some pretty crappy shots of a bluebell and noticed a ladybird on it, so i though ok this could be nice, anyway, this ladybird was moving very slowly and I have 1/1250 shutter, the first 2 where so bad, I could hardly believe my eyes, you can see the images here,

you can hit a large size to see close enough,

what are your thoughts, you can see 2 pictures out of the 4 that are slightly okish, and 2 so badly off,

please visit my website, to understand this isn't user error , or in fact it maybe I have no idea

what do you guys think,

for nearly 3500 pounds worth of kit, should I be getting results like this, Im so deeply unhappy, do i send my camera lens to canon to have a look, i'm not sure, or is this what u get for your money, I believe I would get a better result with a much cheaper micro 4/3rds camera,?

thanks for your time to any one who replies

Kindest regards

Louis

PS sorry for the typos im terrible at spelling
