I want to buy a camera which is good for low light situations. Initially I looked at an entry level Nikon DSLR, (D3200, D3100, or D5100) but noticed that the lens supplied in the kit has a maximum aperture of f3.5. I then looked at two of the cameras in the Nikon CoolPix range, the P7700 with an f2 lens and the P310 with an f1.8 lens. However the P310 with the larger maximum aperture has a smaller sensor than the P7700. And I think that both of these sensors are smaller than that in the DSLR. So given the combined effect of aperture and sensor size, (and other factors???) which of these three cameras is better for low light photography?
Thank you in advance
