Nikon has again impressed me. I'm not looking at this camera as an experienced photographer, but as a dad who's grown daughter is looking at an (affordable) D60 as a way to graduate from a archaic P&S to more serious family photography. The point where my experience comes in is I'd like this in my bag with a 35mm f/1.8 AFS . For my daughter, I'd love to give her this camera; economy different and I would but sans the 35mm.
I think that Nikon has again slotted a camera into the existing lineup so it doesn't have to "replace" the ones currently in the post-production pipe-line. The current ones on the shelf still have their place and take-rate on this model may help make the decision on what falls off the production line - I'm sure they already have this figured out.
For the sensor wise consumer, there's now a D90 and a lesser costly D90, the D5000. The numbering is going to garner some attention over the sales counter as this is a break with the traditional.
I think the D5000 will have lot to offer the entry to mid-level consumer and there are some features I'd consider for myself.
Roger It is still ISO, aperture and shutter speed, right? "Nikonians membership - My most important photographic investment."
