I have two copies of the 18-55lens right now and will be returning one of them.  people mentioned make sure you get a good copy that iS sharp.  How do I test this?  I'm new to this and just want to make sure I keep the better copy.

Simple version of the test - turn OFF OSS lens stabilisation, sit the camera on a steady table/counter, center focus, center metering, ISO 100/200, 2 second timer on the shutter, focus on a dollar bill or wine bottle  label, and take a shot with each lens at e.g. 24mm f5.6 (this lens' sweet spot) with the camera in exactly the same position for both. View the results at 100% (jpg in Windows picture viewer > Actual Size is fine). If one has more fine detail, that's the one to keep!
