I wanna purchase my first DSLR . After a lot of web research I have narrowed down my options to Nikon D5100 /5200 . After reading the specifications for both models i could figure out that D5200 has few advances over D5100 (i) 39 AF points (compared to 11 in D5100) (ii) 9 cross type sensors(compared to 1 in D5100). Would the extra AF points and cross type sensors actually stand out and make an impact, for which i should invest some extra bucks(which is to some extent crossing over my budget) in D5200 over D5100?
