Many recently introduced digital single lens reflex (DSLR) cameras have a new shooting mode called Live View. Live View mode is nothing new for digital cameras. Actually, almost all compact (point and shoot) digital cameras have them. Most people know how slow the auto focus (AF) on P&S camera is. Is Live View really useful for DSLR cameras? Read More…
It was almost a year ago when the news broke that some Canon EOS-1D Mark III DSLR cameras have issues with auto-focus in certain shooting situations and there was even a recall. Now Canon has publish a behind-the scenes story about what happened in its Canon Connection issue #4. It is definitely an interesting read. What I found most amazing is the following:
Canon – and I suspect most any company in any industry – is not prone to go out and announce a problem unless there’s a solution to go along with it. This is particularly true for a product that is selling well, and the the majority of customers weren’t having a problem with.
Nice excuse! We can feel sorry for the poor souls who had to suffer through the headaches and pains of dealing with the AF problems. Unfortunately, what was said is likely true.

The layouts of the auto focus (AF) sensors in the viewfinders of some Canon, Nikon and Sony DSLR cameras are compared with rule-of-the-third grid lines superimposed, thanks to the DPReview forum member Matt Cham.
If you want to shoot with the rule-of-the-third composition, you may find it a little bit tricky on these viewfinders to auto focus at exactly the 1/3 points. The focus and recompose technique can still be useful, even with so many AF sensor points on some models.
