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?
