Have a Nikon D70 along with a 50mm 1.8 & 18-200 zoom. Thoroughly enjoyed it, and really pleased with some results (within a very amateur realm!). But getting slightly frustrated at a couple of things - the LCD display is v small, so when 'playing' it's often hard to get a decent impression of what the picture will look like, and as such, unsure of what settings to change. It seems a bit noisy above ISO 400. And can struggle a bit when blowing up pics as file size is pretty small.
But overall it's been great. Want to stick to Nikon because of lenses. So is a step up to a D90 significant enough (it seems it'll start to resolve above issues) or are there other Nikons to consider?
Many thanks
