truly.. a good and pure confession by prosumer migrate to DSLR..

my advise.. get a TT or gathering.. group photo activities.. learn more about how to use this camera..

search more in internet.. manual.. post ur picture.. let them critic.. ask if u not understand.. but be sure.. u read manual first..

if u in limited budget.. just get sb400..(around rm400-500) it small.. purely compatible with ur camera..

one thing... using dslr.. u will end up with choices of lens
u can have a purely WIDE angle.
or.. telefoto..
or wide open aperture.. perhaps up to 1.4
or small aperture F22..or more for landscape..
or fish eye
or mm

BTW i'm still with my S3IS.. kekekek

i think u have enough justification here to read..
never regret on your purchase... if u have passion in photography.. definitely getting dslr is a next step...

thevoip.. 1.2?? .. RM$$$$$$

go for 18-200 ... one lense.. cover it all..

digital darkroom?

mmm.. personally.. in the early stage, almost all picture i took mus be edited.. but now lazy enough to do so.. just play bit with curve and crop.. that all.. unless u need super power picture like super kewl HDR effect, or else..
