Nikon's stupidly small sensor and pretty much complete point and shoot controls ethos go against everything the CSC is about in my opinion.
Cool, thanks. We were looking at the Sony's. I'll try and find a 5n although there's no built in flash with that is there?
Super fast AF, the deep focus field and good performance at ISO3200 makes it very well suited for close quarters reportage work. Nikon are so close to creating a system that pros would want to shoot with, its a shame that it seems they're going down the consumer route with this.
The Sony's are nice but as soon as you want a fast prime or a telephoto you suddenly end up with a huge camera setup again, you might as well just go for an entry model DSLR. Even the slow 18-55mm dwarfs the cameras. Limited lens choice to date
Nikon 1 are lighting fast in all aspects and the IQ is top notch given the sensor size. Entry level orientated bodies so far and not many lenses either.
M43, mature, plenty of lenses, some nice small fast primes. The older bodies are cheap but have relative poor IQ, the new models with the 16MP sony sensor appear to rock. with both Olympus and Panasonic making lenses, as well as 3rd party manufactures like sigma and SLR magic due to the more open standards, there should be plenty of lenses to come. They have now figured out how to make high quality lenses in small sizes. M43 got a lot more attractive in he last 6 months.
The rest are all a bit limited in some way, even if the cameras are nice. Samsung CSC line is very nice but how quijcly can they release new models and lenses? Same goes for Fuji X. The Canon M has an aging sensor and the so called hybrid Af with phase detection is really bad.
There just is no comparison between sizes on the Sony's and DSLR's. they are just so much bigger and heavier however the bigger the lense of course the camera gets bigger but the same is true with a dslr.
Really you need to go and try a few out.
The Panasonic GX1 can be had pretty cheaply now and plenty of lenses available for M4/3. £500 would get you body with the standard 14-42 kit lens (not the power X lens) with maybe enough cash left over to get the 20mm prime as well.
But as said go try a couple out and see what you like.
