Re: Canon 30D focus autofocus accuracy with f/1.8 lens



I recently bought the 350D with the 18-55 kit lens. I too am
disappointed with the auto focus results, far too many shots are fuzzy
and are simply not in focus. I've been looking at some of the pics
taken with my old point and shoot Sony...hate to admit it but they
compare favourably. I'm reluctant to splash out on a lens in case
matters don't improve.

I got the 50 mm f/1.8 AF lens for my new Canaon 30D.

It is much sharper than the 18-55 zoom that comes with the
camera, at f/3 to f/8 or so.

The autofocus works good enough on three dimensional
objects. I'm using only the central focus spot.

But for flat subjects like books or walls, or more
importantly focusing on a subject all of which is
effectively at infinity, it is nowhere near good enough.
Is this to be expected? I have to manually focus, which is
not exactly easy with the flat matte screen with no focus aids.

What good is autofocus if it does not work? Why don't they
have visual focusing aids like in my old Minolta X-700?
