I'm a dummy when it comes to DSLRs, having used compacts for
most of my life. But the mirrorless SLDs look attractive to me as a
bridge to SLRs, and the low-light photos appear to be better
too.
I can see how the GF1's low light performance would be a leap
ahead of that of point-and-shoots, but ultimately the Four Thirds
sensor isn't great at low light and I expect that it would only be
a matter of time before you were dissatisfied with its low-light
performance.
If you're looking to jump to DSLRs, I'd recommend just getting
one instead of going via an SLD. Keep in mind that the lenses
and other bits of kit wouldn't be compatible unless you stayed with
Olumpus DSLR bodies, and to be frank they're good but not
great.
All in all, speaking from experience, incremental improvements
come with the risk of ending up being more expensive if you go
whole hog. I went from this:
to this:
to this:
and finally to this:
If I'd gone straight for the 5D from the get-go, I'd have saved
a good couple of grand. If you figure you're going to get a
DSLR, bite the bullet and go straight for it - you'll do yourself a
favour.
