hey fellow CSers... i just got my canon 10D about a month ago and been borrowing my friends lens since then.. So now, kinda decided to buy my FIRST lens.. Yay!! So i need all your advices as to decide what lens to buy as a first lens..(been considering 50mm f1.8 and 28-105mm f2.8-4) Unfortunately, i got a tight budget that is below S$800 (since still new in photography, so decided not to go all out first) yup, so feel free to share your experience from your past and give me a good advice... Thank you in advance...
