Hi everybody; I've bought a Pentax K10D body without its kit lens according to my friends' advices which tell the kit lenses were not good enough. So do you have any advice for me to buy which lenses. Or I plan to buy; 1.Sigma 17- 70mm F2. 8- 4. 5 DC MACRO lens and 2. Sigma 70- 300 Apo DG Macro lens These lenses are suitible with Pentax K10D and i have enough money for them. Do you think these are good enough for a beginner like me or can you advice any other? Thank you very much..
