between the d600 and the d7100 - i will hold of for now.
almost bought a d600 a few months back. talagang babayaran ko na lang sa counter pero nagdalawang isip ako. that same day kasi lumabas yung d7100 and i got to test it first hand sa b&h photo NY. natigilan ako kasi after ko silipin sa ipad yung pics from both cameras - using 50mm 1.4 - i cant see any difference.
way before that, i sold my d90 because after using the fuji x100, the d90 cant compete in IQ and dynamic range. it was a 2-year gap bago nalamangan ng point and shoot yung d90. but what i've seen with the d600 and d7100, i think kaya pa mag improve ng DX sensors in a shorter period of time.
i'll wait one more year for the next DX body to come out and i'll probably get that instead of FX. yung pera kong nasave from buying a d600 will go to the best DX lenses instead.
