Am very close to pulling the trigger on one of these cameras as, sadly, I just do not enjoy using my SLR anymore
The swapping on lenses has become too much of a hassle and the kit takes up too much space in my hand luggage on trips.
Before I get rid of the kit (400D, 50mm prime, 10-20 Sigma, 55-250 IS and 18-55 kit plus Crumpler bags) , will I get similar image quality- granted it is a smaller sensor but the sample pics I have seen look fantastic.
Probably the closest in terms of IQ is the 40D.
Similar number of pixels.
40D is better at ISO 100, X10 is better at high ISO.
X10 lens has WAY better IQ than the older Canon kit lens.
Both the X10 and 40D are capable of producing decent A3 prints, but in terms of pure IQ the 60D/7D with the latest kit lens has them beat.
There is also a mindset thing....
People don't think twice about resting a DSLR on a wall, etc, to steady the shot, but will happily use a P&S one handed at arms length.
If you want the best possible IQ, then you have to make a conscious decision to stop treating it like a toy, and start treating it like a proper camera.
Maybe it was just me
Edited to add.....
I'm soon off on a camera club tip to Copenhagen; I'm only taking the X10.
This is despite one of my top 3 images from 2011 being taken on last year's club trip to Portugal.
The is X10 good enough to produce that image printed to A3; or I'd be also taking a DSLR.
Things have moved fast!
Last year everybody had a DSLR and a few people also has a P&S with them for convenience (mine was an LX3).
This year everyone is using a P&S as their main camera and a few people are taking their DSLRs 'just in case'.
