[quote name='mkg12']Digital SLR's are better for low light conditions, no question, compared to point and shoot cameras, correct? Maybe I have it wrong. There is more glass yes, but the lens is much bigger so it is able to gather more light.[/QUOTE]
If we're just talking about camera (lens) vs light then no. Pound for pound compacts handle light better, the lens is smaller, closer to the plane of capture, they get a better depth of field but all of this comes at a price and that's usually image quality but with lower resolutions it might not even matter. Judging from the specs of the
cyber-shot the lens at it's furthest point is 72mm from the sensor but it's equivalent in 35mm format is 432mm, that's 6x the distance and that's just the length. The diameter of the lens goes up as well. Just for the telephoto aspect of it you're looking at a lens that's roughly 13.75" in length and 6.5" in diameter that weighs close to 12lbs. So you have it right the lens is MUCH bigger and much more
expensive
[quote name='mkg12']So what is your solution to noise? I guess he can keep it at a lower setting. I mean all digital cameras will have noise if you turn up the ISO. He can play around with other settings. Low light is low light though.[/QUOTE]
You're right, there's not much you can do, light is light. You have to know how to approach each type differently. What I would suggest is taking a course in photography, especially if you're going to be dealing with DSLRs. You need to know how to deal with it in a manual sense, trust me the automatic settings are never your friend. I would even suggest taking a film based course (SLR) if you can't find a digital based one that deals
specifically with DSLRs. Film is where it started and all the rules of lighting and metering still apply. I'm not saying you can't just "point and click" with a DSLR but you'll be much happier if you know what you're doing.
