Was going to buy the SX40 tomorrow but it looks like I will probably pass...

I've never encountered the problems you describe and have done quite a bit of night photography. if you can point me to resources i'd be interested in reading them.

[quote=JoeM]One of the things I want to do is take night photos at higher ISOs in very low light, like the reviewer. Looks like the SX40 will not be able to handle that.

I'm a bit confused about this need. The limitation is dependent upon shutter speed. If shutter speed is longer than 1 sec then you need to use a tripod. if you need to use a tripod then 1s or 15s doesn't really matter.
I'm still a bit confused myself and still trying to learn about shooting in low light so maybe you or someone more experienced could clarify a bit.

From what I have read, higher ISO has noise no matter but the noise is a little more uniform (much like film grain) where long exposures at low ISO settings can cause chunky and colored noise. Although I haven't tried it yet, I've read that Noise Ninga or stacking can reduce the noise in higher ISO shots and that technique is preferrable when taking star shots/ night sky shots and others at night.

I have taken photos with my Rebel XT at night with very little light available that were shot at ISO 400 with a 4 sec exposure. From what I am reading here, I would not be able to do this with the SX40.
Here's a couple of things I've looked at:

Would appreciate your thoughts.
