I'm still trying to pick an upgrade for our family camera. I was picking between RX100 or an LX7. RX100 is a bit more expensive hence I was still hoping the price would drop a bit more. Then I chance upon new cameras ie. Canon S120 and Canon G16. I'm still not sure how it differs. The difference I can see is the aperture. S120 has (F1.8-5.7) G16 has (F1.8-2.8) and size. I was told the lower the number, the better. I'm also trying to figure out which has a faster speed on shot to shot time. I don't know which spec to look out for. I happens in my Canon Sx240. I click one shot, then it seems to process a few seconds before it can allow me to click another shot. By that tiime the moment is lost and this happens a lot during school programs. Hence this speed is important for me. What terms among the spec should I look into? Which among the cameras has the fastest shot to shot speed? Is the new S120 better than the LX7 in low light situations? Hope someone can enlighten me with your insights or experience. Thanks.
