My personal preference:

for a DSLR, I prefer Nikon because the parts are easily available in my area, especially the lenses from third party like Tamron and Sigma, which can save me more money than buying the original Sony or Pentax lenses. Pentax and Sony lenses are just difficult to acquire in my area.

for PNS…
I like the Canon S95 and S90 a lot. I prefer them than any PNS out there because both cameras can fit in my jeans pocket, which means that I can have a camera every time. An alternative for them, if the price is too high would be the Lumix FH20 < >, For extended zooms, that would be a toss-up between the Canon, Nikon, and Lumix.

Let me start off by saying Nikon D5000 my first DSLR. I wanted to be able to take great pictures of my newborn + I wanted get into amateur photography. DSLR have always seemed a bit intimidating but once you take the time to check out the features and read some of the manual (I'd be lying if I said I read the whole thing) it all comes together and the results are great pictures.

Mine came with the 18-55mm and its definitely does a great job. I eventually added a 55-200mm and a fixed 35mm lens to my bag. The one thing to know about this camera when it comes to upgrading your lens is that the D5000 does not have an auto-focus motor IN the camera. You'll need to get a lens that has the AF-S motor built into the lens. This is a very important detail. If you're buying a lens, make sure it says DX and AF-S.

The HD video capabilities have been a great and useful feature of this camera. I've taken tons of video of my newborn in 740p. Be sure to go into your video menu and actually select 740p. For a while I was wondering why my videos weren't looking so great. It helps to read the manual.
Another thing about recording video. You won't be able to auto focus while recording. You'll have to focus first, then record. Otherwise you'll have to set it to manual focus and adjust on the fly. I just record from a fixed position.

For a beginner like me, the camera has a wide range of preset options from standard portrait, to pet portrait, food setting, sports setting and many more. It also has manual settings that you can customize. I'm glad to say I've moved from preset to manual in just a couple months.

Overall, I have been completely satisfied with this purchase. Its probably the first time I've bought something and didn't have buyer's remorse. If you purchase this camera, take the time to learn about its nifty features.
