Hi everyone!

Recently I've been noticing my 400D tends to back focus alot more than usual, regardless of which lens I use. Though also I've been taking alot of low light pics, but then I was just wondering. Is the phenomena of back focusing considered part and parcel or is it something that needs to be addressed and fixed like a dirty sensor?

How much back focusing is abnormal will depend on how much you cabn accept. for me i demand perfectly focusing, that's why ,by feeling i always manually compensate by turning the focusing ring.

Get it fixed. I would not accept any amount of back focus.
