I'd say it's due to the f/2.8.
Try with a small aperture (f/8.0) to get a larger depth og field (DOF)
The "soft" grass in the lower corners (whitch is closer to you), is due to the small DOF.

Not really... it's actually a feature that a lot of people would pay extra to get even less of ! :lol:

Portrait for example where you want the subject to remain sharp in contrast to the blurry background, ie shallow DOF... For landscape you would want the reverse, ie larger DOF to maintain everything in focus like Fly advised.

Hi,

Not sure if your camera has it but mine has a portrait mode - this apparently makes the edges a little softer but keeps the focus in the centre.

Is it possible that the camera could have been in this mode by mistake??

Just a thought...
