鏡頭舊了,就比較大机會出現這問題,24-70的歷史比24-105長久很多,所以多點發生也正常,一枝用了＋年,一支兩年,都係買50d,1系和5系m2,就可以自己tune番正.

My newly bought 24-70 suffered too.
I visit the customer service twice and it spend 1 month to correct it.
Although it is a old design lens, I don't know why Canon don't modify it to prevent focus problem in the new problem as they fix the bug of the camera.

Canon EOS 50D 下放了自動對焦微調功能，按個別鏡頭進行調整。The new Canon's Body will include this function to adjust and solve
走焦問題.

Many people said their 24-70 suffered focus mainly at 24mm.
My 24-70 suffered at 70mm but correct focus at 24mm. I don't think this can be corrected with simple adustment of the body.
