Here is a look at the specification, side-by-side:

I can see why it is difficult to decide.
At this point I would suggest that you go to a camera store and get your hands on both cameras. This will often help you decide.
Additional lenses have nothing to do with the amount of megapixels.
One conversion lens will entend the maximum optical zoom by about 60 percent.
One conversion lens will change the focal length to wide angle (you can get more people in the picture).
Good quality conversion lenses cost a little over $100 each.

Hi
I'm completly torn about what camera to buy, I've done the research and have narrowed it down to two options, the Pansonic LX1 or Canon A620.
I'm looking for something relatively small, since I'm more likely to carry it in a purse than my pocket it doesn't have to be that small, but still light. I'm trading in my old film SLR which I have never learned to use well enough to get full use, however, I don't want to give up the manual options for when i feel like doing a little more with the camera. So I'm still looking for something full featured.
I've been leaning towards the Panasonic LX1, but I'm a bit concerned by the reports of noise, and also there is no lens thread. However the quality of the lens seems way above others, and it has the 16:9 aspect ratio which is very cool, and it is both smaller and lighter.
Alternatively I'm considering the Cacon A620 because I can buy an additional tele lens. but again, it is slightly larger...
However I've never used an extra lens on a compat camera, how well does it really work, how much difference does it make, and is it really need with a 7 or 8 Megapixel camera?
Thanks!
