Hi Welcome aboard.
What focal length are you looking for, personally I find wide angle more useful than a longer zoom.
the Panasonic as its got a 24-384 zoom instead of the Canon 310 which is 28-225. The 24 wide angle is worth having. But there is a Canon 300 it comes with 24-120 zoom.
I would pick that instead.
The Panasonic sounds like a great package, the canon may have the edge in image quality, see Gordon`s review. "Patchy image quality even at 100 ISO. Noisy throughout ISO range."
I would be deciding what size body I wanted and then look for wide angle zoom starting at 24 and decent IQ with good performance in low light, not having a lens cap is nice.
