E520 or E620 kit?

[chrismaddox3d]

Hi i am new to the forums my name is Chris,
I am looking at both the E520 kit and the E620 kit on amazon.
Olympus Evolt E520 10MP Digital SLR Camera with 14-42mm f/3.5-5.6 and 40-150mm f/4.0-5.6 ED Zuiko Lenses[/B]
or
Olympus Evolt E620 12.3MP Live MOS Digital SLR Camera with Image Stabilization and 2.7 inch Swivel LCD w/ 14-42mm f/3.5-5.6 and 40-150mm f/4.0-5.6 ED Zuiko Lenses
There is like $166 difference in price,
Is there that much difference between the 2 SLR cameras?
This is my first SLR to ever own.
I plan on taking it with me to Shanghai China This summer to take some nice photos,
Also i heard that these cameras can use other brand lenses example like canon?
Any help would be much appreciated,
Thanks,Chris
