Having a bit of fun, definitely a difference between the iPhone and the 450D!
A great day out with fellow pbasers smit10pics and mcgarva where they took me around their 'stamping ground' new locations to me. They are always suitably appalled when my iPhone comes out to record the location, so I thought, lets do a comparison - on the basis of this my iPhone will still only be recording the location, mind it did take 5 minutes to clean the 450D image of all the dust spots on the sensor!
