I got my new lens today. It's the Sigma 70-300mm F4-5.6 APO DG Macro. I got hung up using the macro tonight as you can see. Getting clear shots with this at full zoom is going to be a challenge. Tripod and release are a must.
My kit at this point is pretty well set with the Nikon D70, the kit 18-70 Nikon lens, and the above Sigma lens.
