I am a beginner dslr user and i am confused between d3200 and d5100 and a37 as they all lie in my budget,i have read some forums about how to choose a camera but i am still confused.I donot low light photography too much and most of what i capture are landscape photos and sometimes moving objects[I mean with moving objects splashing of seawater or somebody running but i do not mean very fast objects like cars]
