Still new, still many questions. I am looking to replace the 18-55 kit lens that came with my D80. Just want a little sharper glass. All of the listed below are within my budget so to speak so I am just trying to get feed back on people that have used or could suggest a good replacement. Her are my narrowed down choices: Tamron SP 28-75mm f/2.8 XR Di LD-IF Autofocus Zoom Lens for Nikon AF Sigma 24-70mm f/2.8 EX Aspherical DG DF AutoFocus Standard Zoom Lens with Hood for Nikon AF Cameras Sigma 28-70mm f/2.8 EX DG AutoFocus Wide Angle Zoom Lens for Nikon AF-D Cameras Sigma 24-60mm f/2.8 EX DG Aspherical AutoFocus Standard Zoom Lens with Hood for Nikon AF D Cameras Nikon 24-120mm f/3.5-5.6G ED-IF AF-S VR (Vibration Reduction) Wide Angle Telephoto Zoom Nikkor Lens Sigma 17 - 70mm f/2.8-4.5 DC HSM Macro AutoFocus Wide Angle Zoom Lens for Nikon AF Cameras I like the last one (sigma 17-70) as it offers the macro feature as well as a wider 17mm option. I am already going to get the sigma 10-20 or 12-24 for landscape as it would be a favorite to shoot. Any pros or cons form folks here that have experience with these or suggestions? And as for renting the lens, I have looked all over town and called... no one rents them here. A few places will let you walk out and demo a lens but it gives you no real world perspective in a given situation. I am also not opposed to anything that might not be listed. I really dont want to go over 700 for the lens but would consider it. I like saving a little to buy extra accesories. Thanks in advance! PS... I dont use spell check!
