Hello
I'm very new here, and fairly new to digital photography. I bought a Canon G7 digital compact for general purpose photography and although it is great to use and very convenient, I have been a little disappointed with the image quality sometimes, especially at higher ISO settings, with too much noise evident when conditions are a little on the dim side.
From what I've read the issue could be too many pixels on too small a sensor (10 Mpx in this case). Apparently this means that the individual photosites on the sensor are smaller than on, say, a 6 Mpx camera with the same size sensor. It seems that sometimes less really is more.
This leads to my question. Nikon is offering £60 cashback on various dSLRs purchased with a kit lens. This makes the D40 just £270 (double that number to get the US dollar figure) with the 18-55mm lens, which is quite a lot less than I paid for the G7. I understand it is an entry level dSLR with a limitation on lens compatibility, but I assume the lower number of pixels (6 Mpx), on a larger sensor than the G7, should mean that noise is less of a problem and I should get a bit more dynamic range. In addition, from what I've read the ability to shoot in RAW is very attractive. At that price it is hard to resist.
However, for £390 (after cashback) I could get the D40x, which is almost identical except that it has 10 Mpx and the lowest ISO is 100 rather than 200. I'm wary of the higher pixel count because of my experience with the G7, but the lower ISO might be worth having. This also seems like quite a bargain, and my budget doesn't really stretch to anything more than that.
Can anyone help me with this decision? I don't think I need 10 Mpx, but if there isn't much of a downside then I wonder why I shouldn't get the D40x for the lower ISO.
Many thanks
Kevin
