Hi,
Lens ive had for about a year its a canon 18-55 kit lens.
I was using auto AF (all points)
And the photo was only croped slightly. Just the excess water.

I know the kit lens isnt that great but it should produce a better image..?

Then I suppose it boils down to the AF settings.

Handheld should have produced better, prehaps I wasnt steady enough?

Would a tripod sort this out?..I think so, but not always enough time to set one up.
