50mm f1.8 is a cheap lens to start with.. being a college student like me, I dun have money to buy more 'dua-dua-jia' lenses but I love to shoot portraits though. would that make a good portrait lens? as the bokeh is quite good leh - oops advertised myself liaoz.. hope that yu guys can help me on this. as now I am considering to buy an EF 75-300mm f/4-5.6 III.. or should I buy others? please give me some guidance on this. thanks guys.
