I like it a lot, compared to the dslr’s it replaced it’s got far superior high iso capabilities, af is a lot faster and both the viewfinder and rear lcd are great- the resolution of the lcd means you can accurately check focus etc right away. Wireless flash is fantastic as well- first time I’ve had the opportunity to use off camera flash, and it’s a whole new world. Better than a new lens in my opinion.
Downsides are that the lenses at the price points I can afford don’t seem to match the quality of my previous setup, and it hasn’t got weathersealing- at the time I thought that I’d rather save some money, and get a smaller body, than forego the weathersealing- I’m not sure I’d make that call again though. I’m now terrified of getting the stuff wet.
I bought a brand new one a couple of months back off ebay when I had a paypal discount voucher, and I’m glad I did- £705 for body and 18-105mm, which was about £40 under the best high st price then, and paypal gav me 10% off of that, but I think that Nikon have adjusted their rrp’s again in the last week since the announcement of the d5000, with the d90 going up a fair bit. I guess you know to check camerapricebuster- that Amazon price is a few quid under the best price the site was showing when I bought mine, but in light of the rrp increase stuff may go up. Kits only come with the 18-105mm I think- anything else is cobbled together by the shop.
