oh I so sorry, my buget is around 3k, I want to buy a DSLR cuz I want to be a photographer, and I know that it will be a huge investment that why I need some advice in buying one DSLR
First let me be clear about myself. Me a newbie too not some expert or master. And I think I will share with you what a newbie like me was thinking.
Second, I think your big headache is not on what to chose (atleast not the big part of it.) but which way you are heading to, with your new gear. Like myself, When I first lay my hand on my prosumer H50, I start to fall "in love" with photographing. Than about a year later, the lens and flash is starting to become a contraint factor for me. And it was during this time that I found out I like Nite landscape & portrait shot more than other shooting.
Therefore I venture into this DSLR field and got myself a D90 (with 18-105 kit), a 50mm, a 35mm & a SB600 to start off with.
I feels D90 is a nice to hold camera (including button layout and reach of all button) compare to 500D at my time of purchase. (I narrowed down my choice to C or N only).
I need the 50mm mainly for my portrait shot and the 35mm mainly for nite landscape, although I do use 35mm for portrait too. I prefer prime lens at this moment. And a decent external flash is important for my portrait so i got a sb600.
No zoom lens I owned other than the kit lens and it did cover 90% of what i am shooting most of the time.
Allow me to voice my humble advise.
Maybe you can start off with a prosumer or budget DSLR first to understand yourself more in relation to photographing. That might lay a clearer path for you down the road to spend wisely on what you should get. And I belive by that time, you wouldn't be asking what you are asking now.
