OK, here's what I've purchased since my last post. I upgraded to a Nikon D300s DSLR. This replaced my D200 which is now my backup camera. The main reason I purchased this camera was the high ISO ability. This suits my photo style very nicely since I do lots of late might photoshooting.

Also, I just purchased a uber Nikon lens, the AF-S Nikkor 24-70mm f/2.8G ED. Wow, this lens far exceeds my expectations. I took it out as soon as it came in. Plug alert, I purchased it from B&H Camera in NYC. This piece of glass is to replace the Tamron 28-75mm f/2.8 that I posted about earlier. The Tamron is a fine lens, it's just that it didn't focus fast enough (or at all) in very low light situations. In most lighting or photo situations the Tamron will work fine, but I needed something speedier, and I think I found it. Love it so far. The downside is the huge price (I do this as a hobby so $1,750 is huge) and the weight. It's one of the heaviest lenses I have.
Here is a low light, hand held shot I took the other night. I had the camera set at apeture priority, f/2.8 and auto ISO.
