Hi all! I'm new to this forum and pretty new at this photography lark. I own a Nikon D5000 and I have the kit lens 18-55 VR 3.5-5.6, a Sigma 70-300 5.6 and my lovely Sigma 10-20 4-5.6 wide angle. I currently enjoy taking landscape pictures but I am wanting to try something new. I was thinking about macro and/or portrait photograhy and I am a little confused what would be an ideal all round lens for this type of shooting. I understand that longer focal length lenses are better for portraiture, but I am hoping someone could advise me on a lens that would be suited for both aplications. I was looking at the sigma Sigma 70mm f/2.8 EX DG and I think that would be my limit to my budget. Could anybody advise me if this would be a good option or is there better alternatives available? Unfortunately I dont live near any decent camer shops so I wouldnt be able to go a try them out for myself. Many thanks!
