Wracając do sprawy AF w 550d, niestety mam pewne przesłanki, aby uznać że problem ten trapi również inne aparaty Canona, włączając w to 7d.

Cytat z http://www.expertreviews.co.uk/digit...canon-eos-550d

The auto-focus system has nine points, with the centre being a cross-type f/5.6 point with extra sensitivity at f/2.8. Most of the time the AF system worked well and focuses very quickly, but occasionally we found that it would front focus. This is where the camera focuses slightly in front of your intended subject and is the same issue we saw with both the 450D and 500D. It isn't a major problem if you're using relatively small apertures, but if you're looking to buy fast glass (with a maximum aperture of f/2.8 or larger), it's something to watch out for.

Koniec cytatu.

Z przykrością - potwierdzam
