After getting my Canon EOS 400D Digital back from service, I took a lot of shots with it. There is no back focus issue. However, I still face fail to focus lock issue as I mention at Check Canon EOS 400D Digital with EF 50mm f/1.4 USM back focus issue post.

I took lot of my sister baby photos lately. I faced lot of fail to focus lock issue. I did not use flash on baby. I used ISO 800 and above in low light room. But still failed to focus lock sometime. Is this a common issue with Canon EOS 400D Digital?

I am not satisfied. Therefore, I did some test on it. I took wall as sample. I cannot get a focus lock with built-in flash and without even with ISO 1600. Same applied to plain surface. However, I could get focus lock easily with my Canon Speedlite 580EX II even in very low light environment. Below is the shot I take with Canon Speedlite 580EX II. Is my Canon EOS 400D Digital having focus issue? Or just Canon Speedlite 580EX II is too powerful in focusing?

I have focus problem with my Canon EOS 400D Digital. It does not perform well in low light even using a very fast lens like EF 50mm f/1.4. It have occasional focus hunting in low light environment issue. I am not sure why. It just cannot get a good focus lock. And sometime I did not get a good focus. The photo look like focusing the back of my main object. Therefore, I ran some test on its back focus issue. How to test back focus issue? I use the focus test chart from http://focusTestChart.com. It is very useful.

Here are the result I got.

Updated with Canon response…
Media Transfer Protocol (MTP) USB protocol allow the camera more versatility when connecting to different operating environments. It may be better for the camera to have extra modes like this one, than to not have them embedded in the Menu.
