MashAllah. Congrats. great thinking. I too will get a f1.8 soon. and my aim is to get good quality lens before i get a decent body. for f1.8 prime i have 2 options DX is simple prime with no autofocus (9k) but FX Nikkor f1.8 is with autofocus and is the best quality prime in 1.8 (26k) and will greatly compliment to the lens dept for future investments...
do share its reviews, some picturs of the lens itself and the results...
