Thanks torak for all your info.
But seems like 50mm & 35mm is popular in this market.. But can I say if I would like to take wider, I hv to choose 35mm! But 50mm is sharper? Correct me if I'm wrong..
I don't think I will choose macro lens. As I would like experience on portraits first.. To experience, and step by step..
I never tried the 35mm before, but for the 50mm its very sharp.
However, dont be over concerned with sharpness. The reviews for the 35mm is pretty good as well, so dont let this be ur primary concern.
If u r taking a single person portraiture shot, then i think the 50mm is good enough even when used indoors. For outdoors, its not an issue at all, since u got so much more space to move about.
Personally, both focal lengths are fine for portraiture, u wont go wrong with either of these 2 lenses. But I recommend the 50mm due to the fact that its very cheap (less than $200), and as a beginner its best not to waste too much money 1st IMO.
