This camera is awesome
this is my very first slr.

i had a canon ixus 60 and LX3.
after a few weeks of reading in internet ... kenrocks well .. amazon review ..dpreivew ... and others ...i decide to go for it ... never regret it
i was even trying my friends camrea pentax k10 , 550d ..
pentax was heavy ...550D is about the same weight but it somehow looks bigger than 3100 and of cos ard 1200 ... better live view ( 230k dots vs 100K+ dot ) ...well..i m ok with that..
it "really" is light camrea . . i brought it to my trip and strap around and shoot... for me, weight is a concern.
i don't want to carry heavy camrea all day when traveling and scrolling around donwtown ... (may be for now..i guess )
for me , i didn't really need/want those bells and whistle of those higher end , as i m just starting in photography...
bought from tk photo ...
i was at the same time searched for prime lens
35mm af-s 1.8 DX caught my eye.
read lots of review about that lens and yep, i am pretty convinced that it will be my 1st prime .
it actually happen ...lol
i bought d3100 (with kits) + 35mm prime len @ tk photo..
that len is a beaut . . . low light is great ...sharp..
another thing i likw about this d3100 is it has range finder ...when u do manual focusing , it has an range indicator that go left and right till it has total focus .. pretty neat feature ...
i really do recommend this light weight competent camera for ppl like me who jump to dslr from p/s
cost
weight
feature
and buy 35mm 1.8 .... trust me ...
and buy filter..... really ... i realise the benefit of it , when i do travel .... i have less worry about my len being scrtach and hit ...as i don't have bag ... i feel that it is an extra step and take out and put in ... ( may be i haven't caught rain with this camrea yet..ahahah)
for the price of ard 1200, u would get d3100 + 18-55 + 35mm f1.8
